on appeal from the court of appeal for quebec

Municipal law -- By-laws -- Regulation and restriction of pesticide use --  Town adopting by-law restricting use of pesticides within its perimeter to specified locations and enumerated activities -- Whether Town had statutory authority to enact by-law -- Whether by-law rendered inoperative because of conflict with federal or provincial legislation -- Town of Hudson By-law 270 -- Cities and Towns Act, R.S.Q., c. C-19, s. 410(1).

The appellants are landscaping and lawn care companies operating mostly in the greater Montreal area, with both commercial and residential clients.  They make regular use of pesticides approved by the federal Pest Control Products Act in the course of their business activities and hold the requisite licences under Quebec’s Pesticides Act.  In 1991 the respondent Town, located west of Montreal, adopted By-law 270, which restricted the use of pesticides within its perimeter to specified locations and for enumerated activities.  The definition of pesticides in By-law 270 replicates that in the Pesticides Act.  Under s. 410(1) of the Quebec Cities and Towns Act (“C.T.A.”), the council may make by-laws to “secure peace, order, good government, health and general welfare in the territory of the municipality”, while under s. 412(32) C.T.A. it may make by-laws to “regulate or prohibit the . . . use of . . . combustible, explosive, corrosive, toxic, radioactive or other materials that are harmful to public health or safety, in the territory of the municipality or within l km therefrom”.  In 1992 the appellants were charged with having used pesticides in violation of By-law 270.  They brought a motion for declaratory judgment asking the Superior Court to declare By-law 270 to be inoperative and ultra vires the Town’s authority.  The Superior Court denied the motion, and the Court of Appeal affirmed that decision.

Held:  The appeal should be dismissed.

Per L’Heureux-Dubé, Gonthier, Bastarache and Arbour JJ.:  As statutory bodies, municipalities may exercise only those powers expressly conferred by statute, those powers necessarily or fairly implied by the expressed power in the statute, and those indispensable powers essential and not merely convenient to the effectuation of the purposes of the corporation.  Included in this authority are “general welfare” powers, conferred by provisions in provincial enabling legislation, on which municipalities can draw.  Section 410 C.T.A. is an example of such a general welfare provision and supplements the specific grants of power in s. 412.  While enabling provisions that allow municipalities to regulate for the “general welfare” within their territory authorize the enactment of by‑laws genuinely aimed at furthering goals such as public health and safety, courts faced with an impugned by-law enacted under an “omnibus” provision such as s. 410 C.T.A. must be vigilant in scrutinizing the true purpose of the by-law.

By-law 270 does not fall within the ambit of s. 412(32) C.T.A.  There is no equation of pesticides and “toxic . . . materials” either in the terms of the by-law or in any evidence presented during this litigation.  Since there is no specific provision in the provincial enabling legislation referring to pesticides, the by-law must fall within the purview of s. 410(1) C.T.A.  By-law 270 read as a whole does not impose a total prohibition, but rather permits the use of pesticides in certain situations where that use is not purely an aesthetic pursuit.  Based on the distinction between essential and non-essential uses of pesticides, it is reasonable to conclude that the Town by-law’s purpose is to minimize the use of allegedly harmful pesticides in order to promote the health of its inhabitants.  This purpose falls squarely within the “health” component of s. 410(1) C.T.A.  The distinctions impugned by the appellants as restricting their businesses are necessary incidents to the power delegated by the province under s. 410(1) C.T.A.  Moreover, reading s. 410(1) to permit the Town to regulate pesticide use is consistent with principles of international law and policy.  The interpretation of By-law 270 set out here respects international law’s “precautionary principle”.  In the context of the precautionary principle’s tenets, the Town’s concerns about pesticides fit well under their rubric of preventive action.

By-law 270 was not rendered inoperative because of a conflict with federal or provincial legislation.  As a product of provincial enabling legislation, By-law 270 is subject to the “impossibility of dual compliance” test for conflict between federal and provincial legislation set out in Multiple Access.  The federal Pest Control Products Act regulates which pesticides can be registered for manufacture and/or use in Canada. This legislation is permissive, rather than exhaustive, and there is no operational conflict with By-law 270.  The Multiple Access test also applies to the inquiry into whether there is a conflict between the by-law and provincial legislation.  In this case, there is no barrier to dual compliance with By-law 270 and the Quebec Pesticides Act, nor any plausible evidence that the legislature intended to preclude municipal regulation of pesticide use.  The Pesticides Act establishes a permit and licensing system for vendors and commercial applicators of pesticides and thus complements the federal legislation’s focus on the products themselves.  Along with By-law 270, these laws establish a tri‑level regulatory regime.

Per Iacobucci, Major and LeBel JJ.:  The basic test to determine whether there is an operational conflict remains the impossibility of dual compliance.  From this perspective, the alleged conflict with federal legislation simply does not exist.  Nor does a conflict exist with the Quebec Pesticides Act, for the reasons given by the majority.

The issues in this case remain strictly first whether the C.T.A. authorizes municipalities to regulate the use of pesticides within their territorial limits, and second whether the particular regulation conforms with the general principles applicable to delegated legislation.  The Town concedes that the only provision under which its by-law can be upheld is the general clause of s. 410(1) C.T.A.  While it appears to be sound legislative and administrative policy, under general welfare provisions, to grant local governments a residual authority to address emerging or changing issues concerning the welfare of the local community living within their territory, it is not enough that a particular issue has become a pressing concern in the opinion of a local community.  This concern must be closely related to the immediate interests of the community within the territorial limits defined by the legislature in a matter where local governments may usefully intervene.  In this case, the by-law targets problems of use of land and property, and addresses neighborhood concerns that have always been within the realm of local government activity.  The by-law was thus properly authorized by s. 410(1).

Two basic and longstanding principles of delegated legislation state that a by-law may not be prohibitory and may not discriminate unless the enabling legislation so authorizes.  While on its face, By-law 270 involves a general prohibition and then authorizes some specific uses, when it is read as a whole its overall effect is to prohibit purely aesthetic use of pesticides while allowing other uses, mainly for business or agricultural purposes.  Moreover, although the by-law discriminates, there can be no regulation on such a topic without some form of discrimination in the sense that the by-law must determine where, when and how a particular product may be used.  An implied authority to discriminate was thus unavoidably part of the delegated regulatory power.

The judgment of L’Heureux-Dubé, Gonthier, Bastarache and Arbour JJ. was delivered by

1                                   L’Heureux-Dubé J. – The context of this appeal includes the realization that our common future, that of every Canadian community, depends on a healthy environment. In the words of the Superior Court judge: “Twenty years ago, there was very little concern over the effect of chemicals such as pesticides on the population. Today, we are more conscious of what type of an environment we wish to live in, and what quality of life we wish to expose our children [to]” ((1993), 19 M.P.L.R. (2d) 224, at p. 230).  This Court has recognized that “[e]veryone is aware that individually and collectively, we are responsible for preserving the natural environment . . . environmental protection [has] emerged as a fundamental value in Canadian society”: Ontario v. Canadian Pacific Ltd., [1995] 2 S.C.R. 1031, at para. 55. See also Friends of the Oldman River Society v. Canada (Minister of Transport), [1992] 1 S.C.R. 3, at pp. 16-17.

2                                   Regardless of whether pesticides are in fact an environmental threat, the Court is asked to decide the legal question of whether the Town of Hudson, Quebec, acted within its authority in enacting a by-law regulating and restricting pesticide use.

3                                   The case arises in an era in which matters of governance are often examined through the lens of the principle of subsidiarity. This is the proposition that law-making and implementation are often best achieved at a level of government that is not only effective, but also closest to the citizens affected and thus most responsive to their needs, to local distinctiveness, and to population diversity. La Forest J. wrote for the majority in R. v. Hydro-Québec, [1997] 3 S.C.R. 213, at para. 127, that “the protection of the environment is a major challenge of our time. It is an international problem, one that requires action by governments at all levels” (emphasis added). His reasons in that case also quoted with approval a passage from Our Common Future, the report produced in 1987 by the United Nations’ World Commission on the Environment and Development. The so-called “Brundtland Commission” recommended that “local governments [should be] empowered to exceed, but not to lower, national norms” (p. 220).

4                                   There are now at least 37 Quebec municipalities with by-laws restricting pesticides: J. Swaigen, “The Hudson Case: Municipal Powers to Regulate Pesticides Confirmed by Quebec Courts” (2000), 34 C.E.L.R. (N.S.) 162, at p. 174. Nevertheless, each level of government must be respectful of the division of powers that is the hallmark of our federal system; there is a fine line between laws that legitimately complement each other and those that invade another government’s protected legislative sphere. Ours is a legal inquiry informed by the environmental policy context, not the reverse.

I. Facts

5                                   The appellants are landscaping and lawn care companies operating mostly in the region of greater Montreal, with both commercial and residential clients. They make regular use of pesticides approved by the federal Pest Control Products Act, R.S.C. 1985, c. P-9 , in the course of their business activities and hold the requisite licences under Quebec’s Pesticides Act, R.S.Q., c. P-9.3.

6                                   The respondent, the Town of Hudson (“the Town”), is a municipal corporation governed by the Cities and Towns Act, R.S.Q., c. C-19 (“C.T.A.”). It is located about 40 kilometres west of Montreal and has a population of approximately 5,400 people, some of whom are clients of the appellants. In 1991, the Town adopted By-law 270, restricting the use of pesticides within its perimeter to specified locations and for enumerated activities. The by-law responded to residents’ concerns, repeatedly expressed since 1985. The residents submitted numerous letters and comments to the Town’s Council. The definition of pesticides in By-law 270 replicates that of the Pesticides Act.

7                                   In November 1992, the appellants were served with a summons by the Town to appear before the Municipal Court and respond to charges of having used pesticides in violation of By-law 270. The appellants pled not guilty and obtained a suspension of proceedings in order to bring a motion for declaratory judgment before the Superior Court (under art. 453 of Quebec’s Code of Civil Procedure, R.S.Q., c. C-25). They asked that the court declare By-law 270 (as well as By-law 248, which is not part of this appeal) to be inoperative and ultra vires the Town’s authority.

8                                   The Superior Court denied the motion for declaratory judgment, finding that the by-laws fell within the scope of the Town’s powers under the C.T.A. This ruling was affirmed by a unanimous Quebec Court of Appeal.

III. Judgments

A. Superior Court (1993), 19 M.P.L.R. (2d) 224

10                               Kennedy J. held that by-laws are presumed valid and legal. He found that By-laws 248 and 270 were adopted under s. 410 C.T.A. and, thus, did not require ministerial approval to enter into effect. Both by-laws deal with pesticides and not toxic substances and since “pesticides” are not included in s. 412(32), ministerial approval is not required. According to Kennedy J., the Town, faced with a situation involving health and the environment, acted in the public interest by enacting the by-laws in question. Consequently, the Town could rely on s. 410(1) C.T.A. as the legislative provision that enabled it to adopt these by-laws.

11                               Kennedy J. then considered the provisions of the Pesticides Act to determine whether the by-laws conflicted with provincial legislation. He found it clear that the Pesticides Act was enacted with the intention to allow municipalities to adopt by-laws of this nature. In this regard, Kennedy J. cited ss. 102 and 105 to 107 of the Pesticides Act, which envision the creation of a Pesticide Management Code allowing the provincial government to restrict or prohibit pesticides. Section 102 of that Act states that the provisions of the Code are to take precedence over inconsistent by-laws. Yet, given that the Code had yet to come into force, nothing prohibited municipalities from regulating pesticide use in the interim. Kennedy J. thus concluded that there was no conflict between the by-laws and provincial or federal legislation.

B. Court of Appeal, [1998] Q.J. No. 2546 (QL)

12                               Before the Court of Appeal, the Town conceded that By-law 248 was inoperative. Thus, only By-law 270 was at issue. The appellants challenged Kennedy J.’s ruling on two grounds. First, they argued that By-law 270 was inoperative given that it was incompatible with the Pesticides Act. Second, the appellants contended that since the regulation of toxic substances was covered by s. 412(32) C.T.A., Kennedy J. erred in finding that the by-law was enacted under s. 410(1) C.T.A. While the latter provision allows a municipality to enact by-laws considered necessary for public health and welfare, s. 412(32) C.T.A. is concerned with “toxic” materials, and states that by-laws addressing this subject matter require approval from the Minister of the Environment. Given that the Town did not obtain such approval when it enacted By-law 270, the appellants argued that the by-law was invalid.

13                               The Court of Appeal, per Delisle J.A., accepted the Town’s position that By-law 270 was enacted under s. 410(1) C.T.A.  In reaching this conclusion, the court noted that By-law 270 repeated the definition of “pesticide” that is found in the Pesticides Act. This definition makes no reference to terms used in s. 412(32) or to toxicity. Moreover, the C.T.A. itself does not discuss whether pesticides are “toxic . . . materials”, nor does it require ministerial approval for regulations relating to pesticides. No evidence was submitted concerning the toxic character of pesticides. The Court of Appeal also held that By-law 270 furthered the objectives set out in s. 410(1) C.T.A. It reiterated the statements of Kennedy J. that by-laws are presumed to be valid and legal and that there is a presumption that legislators act in good faith and in the public interest. It found that s. 410(1) is a very general enabling clause and must receive a liberal interpretation.

14                               The court agreed with Kennedy J.’s finding that the by-law was enacted by the Town in the public interest and in response to health concerns expressed by residents. The court noted that these concerns were recorded in the Town Council’s meeting minutes and manifested themselves in letters to Council, as well as a petition with more than 300 signatures. Moreover, the Court of Appeal recognized that s. 410 C.T.A. describes when a municipality may not act under its general governance powers. By-laws on subjects contemplated in the Pesticides Act were not included in this list of unauthorized areas of regulation. The appellants argued that s. 410(1) does not permit the Town to ban pesticides. The Court of Appeal held that an absolute ban would be forbidden, but that the by-law does not impose an absolute ban.

15                               The Court of Appeal then examined whether By-law 270 was in conflict with the Pesticides Act and thus inoperative. It found that s. 102 of the Pesticides Act – which states that the Pesticide Management Code and all regulations of the Pesticides Act take precedence over any incompatible municipal by-law – contemplated municipal regulation of pesticide use. The court also commented that the revised version of s. 102, as well as ss. 105 to 107 regarding the Pesticide Management Code, had yet to be enacted. As a result, it held that, as opposed to a real conflict, a potential future incompatibility between the by-law and the Code did not suffice to render the by-law inoperative.

16                               Finally, the Court of Appeal noted that, although not yet in force, the revised version of s. 102 of the Pesticides Act allows municipalities to adopt by-laws concerning pesticides, so long as these are not incompatible with the Pesticide Management Code. At the same time, even if such incompatibility arises, the by-laws can continue to be operative if they relate to landscaping activities, or if they aim to prevent or reduce injury or damage to people, animals, the environment or property. As such, this new regime would enable municipalities to enact by-laws that are more restrictive than the provisions set out in the provincial Pesticide Management Code. Based on these reasons, the Court of Appeal dismissed the appeal, holding that By-law 270 was validly enacted and operative.

IV. Issues

17                               There are two issues raised by this appeal:

(1) Did the Town have the statutory authority to enact By-law 270?

(2) Even if the Town had authority to enact it, was By-law 270 rendered inoperative because of a conflict with federal or provincial legislation?

V. Analysis

A. Did the Town Have the Statutory Authority to Enact By-law 270?

18                               In R. v. Sharma, [1993] 1 S.C.R. 650, at p. 668, this Court recognized  “the principle that, as statutory bodies, municipalities ‘may exercise only those powers expressly conferred by statute, those powers necessarily or fairly implied by the expressed power in the statute, and those indispensable powers essential and not merely convenient to the effectuation of the purposes of the corporation’ (Makuch, Canadian Municipal and Planning Law (1983), at p. 115)”. Included in this authority are “general welfare” powers, conferred by provisions in provincial enabling legislation, on which municipalities can draw. As I. M. Rogers points out, “the legislature cannot possibly foresee all the powers that are necessary to the statutory equipment of its creatures. . . . Undoubtedly the inclusion of ‘general welfare’ provisions was intended to circumvent, to some extent, the effect of the doctrine of ultra vires which puts the municipalities in the position of having to point to an express grant of authority to justify each corporate act” (The Law of Canadian Municipal Corporations (2nd ed. (loose-leaf)), Cum. Supp. to vol. 1, at p. 367).

19                               Section 410 C.T.A. is an example of such a general welfare provision and supplements the specific grants of power in s. 412. More open-ended or “omnibus” provisions such as s. 410 allow municipalities to respond expeditiously to new challenges facing local communities, without requiring amendment of the provincial enabling legislation. There are analogous provisions in other provinces’ and territories’ municipal enabling legislation: see Municipal Government Act, S.A. 1994, c. M-26.1, ss. 3(c) and 7; Local Government Act, R.S.B.C. 1996, c. 323, s. 249; Municipal Act, S.M. 1996, c. 58, C.C.S.M. c. M225, ss. 232 and 233; Municipalities Act, R.S.N.B. 1973, c. M-22, s. 190(2), First Schedule; Municipal Government Act, S.N.S. 1998, c. 18, s. 172; Cities, Towns and Villages Act, R.S.N.W.T. 1988, c. C-8, ss. 54 and 102; Municipal Act, R.S.O. 1990, c. M.45, s. 102; Municipal Act, R.S.Y. 1986, c. 119, s. 271.

20                               While enabling provisions that allow municipalities to regulate for the “general welfare” within their territory authorize the enactment of by-laws genuinely aimed at furthering goals such as public health and safety, it is important to keep in mind that such open-ended provisions do not confer an unlimited power. Rather, courts faced with an impugned by-law enacted under an “omnibus” provision such as s. 410 C.T.A. must be vigilant in scrutinizing the true purpose of the by-law. In this way, a municipality will not be permitted to invoke the implicit power granted under a “general welfare” provision as a basis for enacting by-laws that are in fact related to ulterior objectives, whether mischievous or not. As a Justice of the Ontario Divisional Court, Cory J. commented instructively on this subject in Re Weir and The Queen (1979), 26 O.R. (2d) 326 (Div. Ct.), at p. 334. Although he found that the City of Toronto’s power to regulate matters pertaining to health, safety and general welfare (conferred by the Municipal Act, R.S.O. 1970, c. 284, s. 242) empowered it to pass a by-law regulating smoking in public retail shops, Cory J. also made the following remark about the enabling provision: “There is no doubt that a by-law passed pursuant to the provisions of s. 242 must be approached with caution. If such were not the case, the municipality could be deemed to be empowered to legislate in a most sweeping manner.”

21                               Within this framework, I turn now to the specifics of the appeal. As a preliminary matter, I agree with the courts below that By-law 270 was not enacted under s. 412(32) C.T.A. This provision authorizes councils to “make by‑laws: To regulate or prohibit the storage and use of gun‑powder, dry pitch, resin, coal oil, benzine, naphtha, gasoline, turpentine, gun‑cotton, nitro‑glycerine, and other combustible, explosive, corrosive, toxic or radioactive or other materials that are harmful to public health or safety, in the territory of the municipality or within 1_km therefrom” (emphasis added). In replicating the definition of “pesticides” found in the provincial Pesticides Act, By-law 270 avoids falling under the ambit of s. 412(32). There is no equation of pesticides and “toxic . . . materials” either in the terms of the by-law or in any evidence presented during this litigation. The provincial government did not consider By-law 270 to fall under s. 412(32): see letter of July 5, 1991 from the Deputy Minister of the Environment. As Y. Duplessis and J. Hétu state in Les pouvoirs des municipalités en matière de protection de l’environnement (2nd ed. 1994), at p. 110,

[translation] . . . these subsections concerning “corrosive, toxic or radioactive materials” in no way limit the other more general powers granted to municipalities that could justify municipal intervention in relation to pesticides.

As a result, since there is no specific provision in the provincial enabling legislation referring to pesticides, the by-law must fall within the purview of s. 410(1) C.T.A. The party challenging a by-law’s validity bears the burden of proving that it is ultra vires: see Kuchma v. Rural Municipality of Tache, [1945] S.C.R. 234, at p. 239, and Montréal (City of) v. Arcade Amusements Inc., [1985] 1 S.C.R. 368, at p. 395.

22                               The conclusion that By-law 270 does not fall within the purview of s. 412(32) C.T.A. distinguishes this appeal from R. v. Greenbaum, [1993] 1 S.C.R. 674. In that case, various express provisions of the provincial enabling legislation at issue covered the regulation of Toronto sidewalks. The appellant was therefore trying to expand the ambit of these specific authorizations by recourse to the  “omnibus” provision in Ontario’s Municipal Act. Moreover, that provision, s. 102, stated that “[e]very council may pass such by-laws and make such regulations for the health, safety, morality and welfare of the inhabitants of the municipality in matters not specifically provided for by this Act as may be deemed expedient and are not contrary to law . . . .” (emphasis added). The Court thus held in Greenbaum, at p. 693, that  “[t]hese express powers are . . . taken out of any power included in the general grant of power”. Since the C.T.A. contains no such specific provisions concerning pesticides (nor a clause limiting its purview to matters not specifically provided for in the Act) the “general welfare” provision of the C.T.A., s. 410(1), is not limited in this fashion.

23                               Section 410(1) C.T.A. provides that councils may make by‑laws:

(1) To secure peace, order, good government, health and general welfare in the territory of the municipality, provided such by‑laws are not contrary to the laws of Canada, or of Québec, nor inconsistent with any special provision of this Act or of the charter.

In Nanaimo (City) v. Rascal Trucking Ltd., [2000] 1 S.C.R. 342, 2000 SCC 13, at para. 36, this Court quoted with approval the following statement by McLachlin J. (as she then was) in Shell Canada Products Ltd. v. Vancouver (City), [1994] 1 S.C.R. 231, at p. 244:

Recent commentary suggests an emerging consensus that courts must respect the responsibility of elected municipal bodies to serve the people who elected them and exercise caution to avoid substituting their views of what is best for the citizens for those of municipal councils. Barring clear demonstration that a municipal decision was beyond its powers, courts should not so hold. In cases where powers are not expressly conferred but may be implied, courts must be prepared to adopt the “benevolent construction” which this Court referred to in Greenbaum, and confer the powers by reasonable implication. Whatever rules of construction are applied, they must not be used to usurp the legitimate role of municipal bodies as community representatives. [Emphasis added.]

24                               The appellants argue that By-law 270 imposes an impermissible absolute ban on pesticide use. They focus on s. 2 of the by-law, which states that: “The spreading and use of a pesticide is prohibited throughout the territory of the Town.”  In my view, the by-law read as a whole does not impose such a prohibition. By-law 270’s ss. 3 to 6 state locations and situations for pesticide use. As one commentary notes, “by-laws like Hudson’s typically target non-essential uses of pesticides. That is, it is not a total prohibition, but rather permits the use of pesticides in certain situations where the use of pesticides is not purely an aesthetic pursuit (e.g. for the production of crops)”: Swaigen, supra, at p. 178.

25                               The appellants further submit that the province’s adoption in 1997 of s. 463.1 C.T.A., which states that a municipality may get permission to introduce pesticides onto private property, indicates, by virtue of the principle of expressio unius est exclusio alterius (express mention of one is the exclusion of the other), that the province did not intend to allow municipal regulation of pesticides. I find this argument to be without merit, since, even if this subsequent enactment were  considered to instantiate prior legislative intent, there is absolutely no implication in s. 463.1 C.T.A., a permissive provision, that it is meant to exhaust municipalities’ freedom of action concerning pesticides.

26                               In Shell, supra, at pp. 276-77, Sopinka J. for the majority quoted the following with approval from Rogers, supra, § 64.1:

In approaching a problem of construing a municipal enactment a court should endeavour firstly to interpret it so that the powers sought to be exercised are in consonance with the purposes of the corporation. The provision at hand should be construed with reference to the object of the municipality: to render services to a group of persons in a locality with a view to advancing their health, welfare, safety and good government.

In that case, Sopinka J. enunciated the test of whether the municipal enactment was “passed for a municipal purpose”. Provisions such as s. 410(1) C.T.A., while benefiting from the generosity of interpretation discussed in Nanaimo, supra, must have a reasonable connection to the municipality’s permissible objectives. As stated in Greenbaum, supra, at p. 689: “municipal by‑laws are to be read to fit within the parameters of the empowering provincial statute where the by‑laws are susceptible to more than one interpretation. However, courts must be vigilant in ensuring that municipalities do not impinge upon the civil or common law rights of citizens in passing ultra vires by‑laws”.

27                               Whereas in Shell, the enactments’ purpose was found to be “to affect matters beyond the boundaries of the City without any identifiable benefit to its inhabitants” (p. 280), that is not the case here. The Town’s By-law 270 responded to concerns of its residents about alleged health risks caused by non-essential uses of pesticides within Town limits. Unlike Shell, in which the Court felt bound by the municipal enactments’ “detailed  recital of . . . purposes” (p. 277), the by-law at issue requires what Sopinka J. called the reading in of an implicit purpose. Based on the distinction between essential and non-essential uses of pesticides, it is reasonable to conclude that the Town by-law’s purpose is to minimize the use of allegedly harmful pesticides in order to promote the health of its inhabitants. This purpose falls squarely within the “health” component of s. 410(1). As R. Sullivan appositely explains in a hypothetical example illustrating the purposive approach to statutory interpretation:

Suppose, for example, that a municipality passed a by-law prohibiting the use of chemical pesticides on residential lawns. With no additional information, one might well conclude that the purpose of this by-law was to protect persons from health hazards contained in the chemical spray. This inference would be based on empirical beliefs about the harms chemical pesticides can cause and the risks of exposure created by their use on residential lawns. It would also be based on assumptions about the relative value of grass, insects and persons in society and the desirability of possible consequences of the by-law, such as putting people out of work, restricting the free use of property, interfering with the conduct of businesses and the like. These assumptions make it implausible to suppose that the municipal council was trying to promote the spread of plant-destroying insects or to put chemical workers out of work, but plausible to suppose that it was trying to suppress a health hazard.

(Driedger on the Construction of Statutes (3rd ed. 1994), at p. 53)

Kennedy J. correctly found (at pp. 230-31) that the Town Council, “faced with a situation involving health and the environment”, “was addressing a need of their community.” In this manner, the municipality is attempting to fulfill its role as what the Ontario Court of Appeal has called a “trustee of the environment” (Scarborough v. R.E.F. Homes Ltd. (1979), 9 M.P.L.R. 255, at p. 257).

28                               The appellants claim that By-law 270 is discriminatory and therefore ultra

vires because of what they identify as impermissible distinctions that affect their commercial activities. There is no specific authority in the C.T.A. for these distinctions. Writing for the Court in Sharma, supra, at p. 668, Iacobucci J. stated the principle that:

. . . in Montréal (City of) v. Arcade Amusements Inc., supra, this Court recognized that discrimination in the municipal law sense was no more permissible between than within classes (at pp. 405‑6). Further, the general reasonableness or rationality of the distinction is not at issue: discrimination can only occur where the enabling legislation specifically so provides or where the discrimination is a necessary incident to exercising the power delegated by the province (Montréal (City of) v. Arcade Amusements Inc., supra, at pp. 404‑6). [Emphasis added.]

See also Shell, supra, at p. 282; Allard Contractors Ltd. v. Coquitlam (District), [1993] 4 S.C.R. 371, at p. 413.

29                               Without drawing distinctions, By-law 270 could not achieve its permissible goal of aiming to improve the health of the Town’s inhabitants by banning non-essential pesticide use. If all pesticide uses and users were treated alike, the protection of health and welfare would be sub-optimal. For example, withdrawing the special status given to farmers under the by-law’s s. 4 would work at cross-purposes with its salubrious intent. Section 4 thus justifiably furthers the objective of By-law 270. Having held that the Town can regulate the use of pesticides, I conclude that the distinctions impugned by the appellants for restricting their businesses are necessary incidents to the power delegated by the province under s. 410(1) C.T.A. They are “so absolutely necessary to the exercise of those powers that [authorization has] to be found in the enabling provisions, by necessary inference or implicit delegation”; Arcade Amusements, supra, at p. 414, quoted in Greenbaum, supra, at p. 695.

30                               To conclude this section on statutory authority, I note that reading s. 410(1) to permit the Town to regulate pesticide use is consistent with principles of international law and policy. My reasons for the Court in Baker v. Canada (Minister of Citizenship and Immigration), [1999] 2 S.C.R. 817, at para. 70, observed that “the values reflected in international human rights law may help inform the contextual approach to statutory interpretation and judicial review”. As stated in Driedger on the Construction of Statutes, supra, at p. 330:

[T]he legislature is presumed to respect the values and principles enshrined in international law, both customary and conventional. These constitute a part of the legal context in which legislation is enacted and read. In so far as possible, therefore, interpretations that reflect these values and principles are preferred. [Emphasis added.]

31                               The interpretation of By-law 270 contained in these reasons respects international law’s “precautionary principle”, which is defined as follows at para. 7 of the Bergen Ministerial Declaration on Sustainable Development (1990):

In order to achieve sustainable development, policies must be based on the precautionary principle. Environmental measures must anticipate, prevent and attack the causes of environmental degradation. Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation.

Canada “advocated inclusion of the precautionary principle” during the Bergen Conference negotiations (D. VanderZwaag, CEPA Issue Elaboration Paper No. 18,  CEPA and the Precautionary Principle/Approach (1995), at p. 8). The principle is codified in several items of domestic legislation: see for example the Oceans Act, S.C. 1996, c. 31 , Preamble (para. 6); Canadian Environmental Protection Act, 1999, S.C. 1999, c. 33, s. 2(1) (a); Endangered Species Act, S.N.S. 1998, c. 11, ss. 2(1)(h) and 11(1).

32                               Scholars have documented the precautionary principle’s inclusion “in virtually every recently adopted treaty and policy document related to the protection and preservation of the environment” (D. Freestone and E. Hey, “Origins and Development of the Precautionary Principle”, in D. Freestone and E. Hey, eds., The Precautionary Principle and International Law (1996), at p. 41. As a result, there may be “currently sufficient state practice to allow a good argument that the precautionary principle is a principle of customary international law” (J. Cameron and J. Abouchar, “The Status of the Precautionary Principle in International Law”, in ibid., at p. 52). See also O. McIntyre and T. Mosedale, “The Precautionary Principle as a Norm of Customary International Law” (1997), 9 J. Env. L. 221, at p. 241 (“the precautionary principle has indeed crystallised into a norm of customary international law”).  The Supreme Court of India considers the precautionary principle to be “part of the Customary International Law” (A.P. Pollution Control Board v. Nayudu, 1999 S.O.L. Case No. 53, at para. 27). See also Vellore Citizens Welfare Forum v. Union of India, [1996] Supp. 5 S.C.R. 241.  In the context of the precautionary principle’s tenets, the Town’s concerns about pesticides fit well under their rubric of preventive action.

B. Even if the Town Had Authority to Enact it, Was By-law 270 Rendered Inoperative

     Because of a Conflict with Federal or Provincial Legislation?

33                               This Court stated in Hydro-Québec, supra, at para. 112, that Oldman River, supra, “made it clear that the environment is not, as such, a subject matter of legislation under the Constitution Act, 1867 . As it was put there, ‘the Constitution Act, 1867  has not assigned the matter of “environment” sui generis to either the provinces or Parliament’ (p. 63). Rather, it is a diffuse subject that cuts across many different areas of constitutional responsibility, some federal, some provincial (pp. 63-64).” As there is bijurisdictional responsibility for pesticide regulation, the appellants allege conflicts between By-law 270 and both federal and provincial legislation. These contentions will be examined in turn.

1. Federal Legislation

34                               The appellants argue that ss. 4(1), 4(3) and 6(1)(j) of the Pest Control Products Act (“PCPA”), and s. 45 of the Pest Control Products Regulations allowed them to make use of the particular pesticide products they employed in their business practices. They allege a conflict between these legislative provisions and By-law 270. In Multiple Access Ltd. v. McCutcheon, [1982] 2 S.C.R. 161, at p. 187, Dickson J. (as he then was) for the majority of the Court reviewed the “express contradiction test” of conflict between federal and provincial legislation. At p. 191, he explained that “there would seem to be no good reasons to speak of paramountcy and preclusion except where there is actual conflict in operation as where one enactment says ‘yes’ and the other says ‘no’; ‘the same citizens are being told to do inconsistent things’; compliance with one is defiance of the other”.  See also M & D Farm Ltd. v. Manitoba Agricultural Credit Corp., [1999] 2 S.C.R. 961, at paras. 17 and 40; Bank of Montreal v. Hall, [1990] 1 S.C.R. 121, at p. 151. By-law 270, as a product of provincial enabling legislation, is subject to this test.

35                               Federal legislation relating to pesticides extends to the regulation and authorization of their import, export, sale, manufacture, registration, packaging and labelling. The PCPA regulates which pesticides can be registered for manufacture and/or use in Canada. This legislation is permissive, rather than exhaustive, and there is no operational conflict with By-law 270.  No one is placed in an impossible situation by the legal imperative of complying with both regulatory regimes. Analogies to motor vehicles or cigarettes that have been approved federally, but the use of which can nevertheless be restricted municipally, well illustrate this conclusion. There is, moreover, no concern in this case that application of By-law 270 displaces or frustrates “the legislative purpose of Parliament”. See Multiple Access, supra, at p. 190; Bank of Montreal, supra, at pp. 151 and 154.

2. Provincial Legislation

36                               Multiple Access also applies to the inquiry into whether there is a conflict between the by-law and provincial legislation, except for cases (unlike this one) in which the relevant provincial legislation specifies a different test. The Multiple Access test, namely “impossibility of dual compliance”, see P. W. Hogg, Constitutional Law of Canada (loose-leaf ed.), vol. 1, at p. 16-13, was foreshadowed for provincial-municipal conflicts in dicta  contained in this Court’s decision in Arcade Amusements, supra, at p. 404. There, Beetz J. wrote that “otherwise valid provincial statutes which are directly contrary to federal statutes are rendered inoperative by that conflict. Only the same type of conflict with provincial statutes can make by-laws inoperative: I. . Rogers, The Law of Canadian Municipal Corporations, vol. 1, 2nd ed., 1971, No. 63.16” (emphasis added).

37                               One of the competing tests to Multiple Access suggested in this litigation is based on Attorney General for Ontario v. City of Mississauga (1981), 15 M.P.L.R. 212 (Ont. C.A.). In that case, decided before Multiple Access, Morden J.A. saw “no objection to borrowing, in this field, relevant principles of accommodation which have been developed in cases involving alleged federal-provincial areas of conflict. In both fields great care is, and should be, taken before it is held that an otherwise properly enacted law is inoperative” (p. 232). He added, at p. 233, the important point that “a by-law is not void or ineffective merely because it ‘enhances’ the statutory scheme of regulation by imposing higher standards of control than those in the related statute. This is not conflict or incompatibility per se” (quoting Township of Uxbridge v. Timber Bros. Sand & Gravel Ltd. (1975), 7 O.R. (2d) 484 (C.A.)). See also P.-A. Côté, The Interpretation of Legislation in Canada (3rd ed. 2000), at p. 353 (“In some cases, the courts have held that the provincial statute does not imply full repeal of the municipal power.  The municipality retains its authority as long as there is no conflict with provincial legislation.  It may be more demanding than the province, but not less so”).

38                               Some courts have already made use of the Multiple Access test to examine alleged provincial-municipal conflicts. For example, in British Columbia Lottery Corp. v. Vancouver (City) (1999), 169 D.L.R. (4th) 141, at pp. 147-48, the British Columbia Court of Appeal stated that cases pre-dating Multiple Access, including the Ontario Court of Appeal decision in Mississauga, supra, “must be read in the light of [that] decision”.

It is no longer the key to this kind of problem to look at one comprehensive scheme, and then to look at the other comprehensive scheme, and to decide which scheme entirely occupies the field to the exclusion of the other. Instead, the correct course is to look at the precise provisions and the way they operate in the precise case, and ask: Can they coexist in this particular case in their operation? If so, they should be allowed to co-exist, and each should do its own parallel regulation of one aspect of the same activity, or two different aspects of the same activity. [Emphasis added.]

The court summarized the applicable standard as follows: “A true and outright conflict can only be said to arise when one enactment compels what the other forbids.” See also Law Society of Upper Canada v. Barrie (City) (2000), 46 O.R. (3d) 620 (S.C.J.), at pp. 629-30: “Compliance with the provincial Act does not necessitate defiance of the municipal By-law; dual compliance is certainly possible”; Huot v. St-Jérôme (Ville de), J.E. 93-1052 (Sup. Ct.), at p. 19: [translation] “A finding that a municipal by-law is inconsistent with a provincial statute (or a provincial statute with a federal statute) requires, first, that they both deal with similar subject matters and, second, that obeying one necessarily means disobeying the other.”

39                               As a general principle, the mere existence of provincial (or federal) legislation in a given field does not oust municipal prerogatives to regulate the subject matter. As stated by the Quebec Court of Appeal in an informative environmental decision, St‑Michel‑Archange (Municipalité de) v. 2419‑6388 Québec Inc., [1992] R.J.Q. 875 (C.A.), at pp. 888-91:

[translation] According to proponents of the unitary theory, although the provincial legislature has not said so clearly, it has nonetheless established a provincial scheme for managing waste disposal sites.  It has therefore reserved exclusive jurisdiction in this matter for itself, and taken the right to pass by-laws concerning local waste management away from municipalities.  The Environment Quality Act therefore operated to remove those powers from municipal authorities.

According to proponents of the pluralist theory, the provincial legislature very definitely did not intend to abolish the municipality’s power to regulate; rather, it intended merely to better circumscribe that power, to ensure complementarity with the municipal management scheme. . . .

                                                                   . . .

The pluralist theory accordingly concedes that the intention is to give priority to provincial statutory and regulatory provisions.  However, it does not believe that it can be deduced from this that any complementary municipal provision in relation to planning and development that affects the quality of the environment is automatically invalid.

                                                                   . . .

A thorough analysis of the provisions cited supra and a review of the environmental policy as a whole as it was apparently intended by the legislature leads to the conclusion that it is indeed the pluralist theory, or at least a pluralist theory, that the legislature seems to have taken as the basis for the statutory scheme.

In this case, there is no barrier to dual compliance with By-law 270 and the Pesticides

Act, nor any plausible evidence that the legislature intended to preclude municipal

regulation of pesticide use. The Pesticides Act establishes a permit and licensing

system for vendors and commercial applicators of pesticides and thus complements the

federal legislation’s focus on the products themselves. Along with By-law 270, these

laws establish a tri-level regulatory regime.

40                               According to s. 102 of the Pesticides Act, as it was at the time By-law 270 was passed: “The provisions of the Pesticide Management Code and of the other regulations of this Act prevail over any inconsistent provision of any by‑law passed by a municipality or an urban community.” Evidently, the Pesticides Act envisions the existence of complementary municipal by-laws. As Duplessis and Hétu, supra, at p. 109, put it, [translation] “the Quebec legislature gave the municipalities the right to regulate pesticides, provided that the by-law was not incompatible with the regulations and the Management Code enacted under the Pesticides Act”. Since no Pesticide Management Code has been enacted by the province under s. 105, the lower courts in this case correctly found that the by-law and the Pesticides Act could co-exist. In the words of the Court of Appeal, at p. 16: [translation] “The Pesticides Act thus itself contemplated the existence of municipal regulation of pesticides, since it took the trouble to impose restrictions.”

41                               I also agree with the Court of Appeal at p. 16, that: [translation] “A potential inconsistency is not sufficient to invalidate a by-law; there must be a real conflict”. In this regard, the Court of Appeal quoted, at p. 17, St-Michel-Archange, supra, at p. 891, to the effect that: [translation] “However, to the extent that and for as long as the provincial regulation is not in force, the municipal by-law continues to regulate the activity, provided, of course, that it complies with all the rules established by the law and the courts concerning its validity.”

42                               I note in conclusion that the 1993 revision to the Pesticide Act added a new s. 102 stating:

The Pesticide Management Code and any other regulation enacted pursuant to this Act shall render inoperative any regulatory provision concerning the same matter enacted by a municipality or an urban community, except where the provision

– concerns landscaping or extermination activities, such as fumigation, as defined by government regulation, and

– prevents or further mitigates harmful effects on the health of humans or of other living species or damage to the environment or to property.

This revised language indicates more explicitly that the Pesticides Act is meant to co-exist with  stricter municipal by-laws of the type at issue in this case. Indeed, the new s. 102, by including the word “health”, echoes the enabling legislation that underpins By-law-270, namely s. 410(1) C.T.A. Once a Pesticide Management Code is enacted, municipalities will be able to draw on s. 102 in order to continue their  independent regulation of pesticides. As Duplessis and Hétu, supra, explain at p. 111: [translation] “the Quebec legislature has again recognized that municipalities have a role to play in pesticide control while at the same time indicating that it intends to make the municipal power subordinate to its own regulatory activity”.

VI. Disposition

43                               I have found that By-law 270 was validly enacted under s. 410(1) C.T.A. Moreover, the by-law does not render dual compliance with its dictates and either federal or provincial legislation impossible. For these reasons, I would dismiss the appeal with costs.

The reasons of Iacobucci, Major and LeBel JJ.were delivered by

LeBel J. –

Introduction

44                               I agree with Justice L’Heureux-Dubé that the impugned by-law on pesticide use adopted by the respondent, the Town of Hudson, is valid.   It does not conflict with relevant federal and provincial legislation on the use and control of pesticides and is a valid exercise of municipal regulatory power under s. 410(1) of the Cities and Towns Act, R.S.Q., c. C-19 (“C.T.A.”).

45                               I view this case as an administrative and local government law issue. Although I agree with L’Heureux-Dubé J. on the disposition of the appeal,  I wish to add some comments on some of the problems raised by the appellants.  First, I will discuss the alleged operational conflict with the regulatory and legislative systems put in place by other levels of government.  I will then turn to the difficulties created by the use of broad provisions like s. 410 and the application of the general principles of administrative law governing delegated legislation.

The Operational Conflict

46                               As its first line of attack against By-law 270 of the Town of Hudson, the appellants raise the issue of an operational conflict with the federal Pest Control Products Act, R.S.C. 1985, c. P-9 , and the Pest Control Products Regulations, C.R.C. 1978, c. 1253.  The appellants also assert that the by-law conflicts with the Quebec Pesticides Act, R.S.Q., c. P-9.3.  As L’Heureux-Dubé J. points out, the applicable test to determine whether  an operational conflict arises is set out in Multiple Access Ltd. v. McCutcheon, [1982] 2 S.C.R. 161, at pp. 187 and 189.  There must be an actual conflict, in the sense that compliance with one set of rules would require a breach of the other.  This principle was recently reexamined and restated by Binnie J. in M & D Farm Ltd. v. Manitoba Agricultural Credit Corp., [1999] 2 S.C.R. 961, at paras. 39-42.  The basic test remains the impossibility of dual compliance.  From this perspective, the alleged conflict with federal legislation simply does not exist.  The federal Act and its regulations merely authorize the importation, manufacturing, sale and distribution of the products in Canada.  They do not purport to state where, when and how pesticides could or should be used.  They do not grant a blanket authority to pesticides’ manufacturers or distributors to spread them on every spot of greenery within Canada.  This matter is left to other legislative and regulatory schemes.  Nor does a conflict exist with the provincial Pesticides Act, and I agree with L’Heureux-Dubé J.’s analysis on this particular point.  The operational conflict argument thus fails.

The Administrative Law Issues

47                               The most serious problems raised by the appeal involve pure administrative law issues.  The appellants’ arguments raise some basic issues of administrative law as applied in the field of municipal governance.

48                               The appellants assert that no provision of the C.T.A. authorizes By-law 270.  If such legislative authority exists, the by-law is nevertheless void because of its discriminatory and prohibitory nature.  A solution is to be found in the principles governing the interpretation and application of the laws governing cities and towns like the respondent in the Province of Quebec.  Interesting as they may be, references to international sources have little relevance.  They confirm the general importance placed in modern society and shared by most citizens of this country on the environment and the need to protect it.  Nevertheless, no matter how laudable the purpose of the by-law may be, and although it may express the will of the members of the community to protect their local environment, the means to do it must be found somewhere in the law.  The issues in this case remain strictly, first, whether the C.T.A. authorizes municipalities to regulate the use of pesticides within their territorial limits and, second, whether the particular regulation conforms with the general principles applicable to delegated legislation.

49                               A tradition of strong local government has become an important part of the Canadian democratic experience.  This level of government usually appears more attuned to the immediate needs and concerns of the citizens.  Nevertheless, in the Canadian legal order, as stated on a number of occasions, municipalities remain creatures of provincial legislatures (see Public School Boards’ Assn. of Alberta v. Alberta (Attorney General), [2000] 2 S.C.R. 409, 2000 SCC 45, at paras. 33-34; Ontario English Catholic Teachers’ Assn. v. Ontario (Attorney General), [2001] 1 S.C.R. 470, 2001 SCC 15, at paras. 29 and 58-59).  Municipalities exercise such powers as are granted to them by legislatures.   This principle is illustrated by numerous decisions of our Court (see, for example, Montréal (City of) v. Arcade Amusements Inc., [1985] 1 S.C.R. 368; R. v. Sharma, [1993] 1 S.C.R. 650).  They are not endowed with residuary general powers, which would allow them to exercise dormant provincial powers (see I. M. Rogers, The Law of Canadian Municipal Corporations (2nd ed. (loose-leaf)), Cum. Supp. to vol. 1, at pp. 358 and 364; J. Hétu, Y. Duplessis and D. Pakenham, Droit Municipal: Principes généraux et contentieux (1998), at p. 651).  If a local government body exercises a power, a grant of authority must be found somewhere in the provincial laws.  Although such a grant of power must be construed reasonably and generously (Nanaimo (City) v. Rascal Trucking Ltd., [2000] 1 S.C.R. 342, 2000 SCC 13), it cannot receive such an interpretation unless it already exists.  Interpretation may not supplement the absence of power. 

50                               The appellants argue that no power to regulate the use of pesticides was delegated to municipalities in Quebec, either under a specific grant of power or under the more general provisions of s. 410(1) C.T.A.  The respondent concedes that the only provision under which its by-law can be upheld is the general clause of s. 410(1).  It no longer asserts that it could be supported under s. 412(32) concerning toxic materials. 

51                               As the appellants interpret a general clause like s. 410 C.T.A., it would amount to an empty shell. Any exercise of municipal regulatory authority would require a specific and express grant of power.  The history of the C.T.A. confirms that the Quebec legislature has generally favoured a drafting technique of delegating regulatory or administrative powers to municipalities through a myriad of specific provisions, which are amended frequently.  The reader is then faced with layers of complex and sometimes inconsistent legislation.

52                               In the case of a specific grant of power, its limits must be found in the provision itself.  Non-included powers may not be supplemented through the use of the general residuary clauses often found in municipal laws (R. v. Greenbaum, [1993] 1 S.C.R. 674).

53                               The case at bar raises a different issue:  absent a specific grant of power,  does a general welfare provision like s. 410(1) authorize By-law 270?  A provision like s. 410(1) must be given some meaning.  It reflects the reality that the legislature and its drafters cannot foresee every particular situation.  It appears to be sound legislative and administrative policy, under such provisions, to grant local governments a residual authority to deal with the unforeseen or changing circumstances, and to address emerging or changing issues concerning the welfare of the local community living within their territory.  Nevertheless,  such a provision cannot be construed as an open and unlimited grant of provincial powers.  It is not enough that a particular issue has become a pressing concern in the opinion of a local community.  This concern must relate to problems that engage the community as a local entity, not a member of the broader polity.   It must be closely related to the immediate interests of the community within the territorial limits defined by the legislature in a matter where local governments may usefully intervene.  In Shell Canada Products Ltd. v. Vancouver (City), [1994] 1 S.C.R. 231, the Court emphasized the local ambit of such power.  It does not allow local governments and communities to exercise powers in questions that lie outside the traditional area of municipal interests, even if municipal powers should be interpreted broadly and generously (see F. Hoehn, Municipalities and Canadian Law:  Defining the Authority of Local Governments (1996), at pp. 17-24).

54                               In the present case, the subject matter of the by-law lies within the ambit of normal local government activities.  It concerns the use and protection of the local environment within the community.  The regulation targets problems of use of land and property, and addresses neighbourhood concerns that have always been within the realm of local government activity.  Thus, the by-law was properly authorized by s. 410(1).  I must then turn briefly to the second part of the administrative law argument raised by the appellants, that the particular exercise of the existing municipal power breached principles of delegated legislation against prohibitory and discriminatory regulations.

55                               Two basic and longstanding principles of delegated legislation state that a by-law may not be prohibitory and may not discriminate unless the enabling legislation so authorizes.  (See P. Garant, Droit administratif (4th ed. 1996), vol. 1,  at pp. 407 et seq.; R. Dussault and L. Borgeat, Administrative Law: A Treatise (2nd ed. 1985), vol. 1, at pp. 435 et seq.; Hétu, Duplessis and Pakenham, supra, at pp. 677-82 and 691-96.) The drafting technique used in the present case creates an apparent problem.  On its face, the by-law involves a general prohibition and then authorizes some specific uses.  This obstacle may be overcome through global interpretation of the by-law.  When it is read as a whole, its overall effect is to prohibit purely aesthetic use of pesticides while allowing other uses, mainly for business or agricultural purposes.  It does not appear as a purely prohibitory legal instrument.  As such, it conforms with this first basic principle of municipal law.  There remains the problem of the discriminatory aspect of the by-law.  Although the by-law discriminates, I agree with L’Heureux-Dubé J. that this kind of regulation implies a necessary component of discrimination.  There can be no regulation on such a topic without some form of discrimination in the sense that the by-law must determine where, when and how a particular product may be used.  The regulation needed to identify the various distinctions between different situations.  Otherwise, no regulation would have been possible.  An implied authority to discriminate was then unavoidably part of the delegated regulatory power.

56                               For these reasons, the appeal is dismissed, with costs to the respondent the Town of Hudson.
