Joyal,
J.:
—In
these
proceedings
relating
to
an
income
tax
appeal,
the
plaintiff
taxpayer
seeks
an
order
from
this
Court
for
the
production
by
the
defendant
of
certain
confidential
documents
in
its
possession.
These
documents
were
filed
by
a
large
constituency
of
Canadian
pulp
and
newsprint
companies
in
response
to
a
request
by
Revenue
Canada
which
had
commissioned
T.M.
Thomson
&
Associates
Ltd.
of
Victoria,
B.C.,
to
make
a
survey
of
pulp
and
newsprint
pricing
discounts
and
commissions
in
that
industry.
This
required
the
companies
to
make
a
voluntary
disclosure
of
very
confidential
and
sensitive
information
on
their
individual
policies
relating
to
discounts
and
commissions.
To
secure
their
collaboration,
both
the
T.M.
Thomson
people
and
Revenue
Canada
had
to
assure
the
participants
that
the
information
would
be
protected
by
the
strictest
confidentiality.
It
was
on
that
basis
that
the
information
was
voluntarily
disclosed.
It
was
analyzed
by
T.M.
Thomson
and
its
report,
hereinafter
referred
to
as
the
Thomson
Report,
was
produced
in
July
of
1987.
The
Report
is
a
summary
of
the
data
accumulated
relevant
to
its
field
of
enquiry
and
establishes
a
“reasonable
range"
of
arm's
length
pulp
and
newsprint
discounts
and
commissions.
The
Thomson
Report
would
not
have
caused
any
rumblings
were
it
not
for
the
action
taken
by
Revenue
Canada
in
reassessing
the
plaintiff
for
the
years
1984,
1985
and
1986
on
the
grounds
that
the
plaintiff's
discount
allowed
to
its
customers
was
in
excess
of
reasonable
pulp
sales
discounts
in
that
industry
and
such
excess
should
be
added
back
to
the
plaintiff's
income
for
those
years.
The
plaintiff
then
appealed
to
this
Court.
It
became
clear
on
the
exchange
of
pleadings
between
the
parties
arid
on
discovery
of
the
Crown's
witness,
Mr.
H.
M.
Becker,
that
the
Crown's
reassessment
was
on
the
assumption
that
a
reasonable
pulp
sales
discount
was
much
lower
than
the
one
allowed
by
the
plaintiff
and
further,
that
support
for
the
assumption
was
derived
from
the
Thomson
Report
to
which
I
have
referred.
An
"edited"
version
of
the
Report
was
produced
but
the
Crown
properly
objected
to
full
production
of
all
the
supporting
documents
on
the
grounds
that
it
contained
third
party
information
obtained
on
condition
of
confidentiality.
The
Crown
took
the
position
that
unless
such
third
parties
consented
to
the
production,
it
would
only
do
so
pursuant
to
an
order
of
this
Court.
On
December
3
and
on
December
7,
1990,
in
Vancouver,
pursuant
to
a
notice
of
motion
filed
on
November
20,
the
plaintiff
duly
applied
for
an
order
of
production
of
the
documents.
At
that
hearing,
which
was
held
before
me,
counsel
for
a
number
of
pulp
and
newsprint
companies
intervened
and
opposed
the
granting
of
the
order.
A
couple
of
other
companies
did
not
oppose
it.
After
hearing
the
parties
on
various
issues,
it
was
suggested
by
the
Court
that
further
discussions
take
place
between
plaintiff
and
the
intervenors.
The
plaintiff
agreed
to
withdraw
its
motion
and
I
issued
an
order
accordingly.
A
new
notice
of
motion
returnable
January
21,
1991
was
filed
by
the
plaintiff
and
it
came
on
for
hearing
before
Walsh,
D.
J.
Again,
a
number
of
counsel
appeared
and
several
representations
were
made.
If
I
interpret
properly
the
abstract
of
that
hearing,
however,
there
seemed
to
have
developed
some
kind
of
consensus
where
the
documents
might
grudgingly
be
allowed
to
be
produced
subject
to
strict
and
detailed
confidentiality
conditions.
It
was
therefore
left
to
plaintiff's
counsel
to
draft
an
appropriate
order
which
would
be
circulated
to
the
intervenors
for
their
approval.
Unfortunately
that
process
bogged
down
as
specific
terms
and
expressions
in
the
draft
order
were
inserted
or
deleted
by
all
who
had
a
hand
in
it.
Consensus
could
not
be
achieved.
And
so
the
matter
came
on
again
before
the
Court
for
judicial
determination.
Certain
it
is
that
on
the
facts
of
the
case,
there
is
no
dispute.
All
parties
agree
that
the
information
for
which
discovery
is
sought
was
submitted
by
the
several
pulp
and
paper
companies
under
an
undertaking
of
confidentiality.
The
Crown
concedes
this
and
says
that,
in
the
circumstances,
in
no
way
will
it
produce
that
information
without
an
order
of
this
Court.
For
the
rest,
the
Crown
leaves
it
to
the
plaintiff
and
the
several
intervenors
to
battle
it
out.
The
position
taken
by
those
intervenors
who
have
taken
a
strong
position
against
disclosure
is
that
such
would
be
a
breach
of
confidence
which
would
seriously
impair
their
competitive
positions.
In
analyzing
Court
decisions
in
such
cases,
counsel
refers
to
a
number
of
cases
where
a
distinction
was
made
between
the
disclosure
of
confidential
information
imposed
by
law
and
of
information
voluntarily
given.
For
example,
in
M.N.R.
v.
Huron
Steel
Fabricators
(London)
Ltd.,
[1973]
F.C.
808;
[1973]
C.T.C.
422;
73
D.T.C.
5347,
the
Crown
had
resisted
the
disclosure
of
tax
returns
and
financial
statements
of
another
company
which
had
been
used
in
assessing
Huron
Steel.
The
Court
found
that,
on
balance,
the
public
interest
asserted
by
the
Crown
was
outweighed
by
the
public
interest
in
the
proper
administration
of
justice.
On
the
onus
which
a
challenge
to
a
tax
assessment
imposes
on
a
taxpayer,
Thurlow,
J.,
at
page
812,
said
as
follows:
The
onus
which
the
income
tax
law
places
on
a
taxpayer
to
demolish
the
assumed
facts
upon
which
the
taxation
rests
is
not
so
easily
discharged
in
most
cases
as
to
permit
counsel
or
anyone
else
lightly
to
assume
or
to
accept
that
nothing
is
to
be
found
in
the
documents
upon
which
an
assessment
is
based
that
will
either
aid
the
establishment
of
the
taxpayer's
case
or
help
to
destroy
the
Minister’s
assumptions
and
when,
as
here,
the
Minister’s
assumptions
have
admittedly
been
based
on
the
returns
in
question
it
seems
to
me
to
be
manifest
both
that
the
need
of
the
respondents
for
production
of
these
returns
is
made
out,
an
impression
which
to
my
mind
is
reinforced
by
my
examination
of
the
returns,
and
that
a
very
strong
public
interest
in
keeping
them
from
production
would
be
required
to
outweigh
the
public
interest
in
the
proper
administration
of
justice
which
would
be
served
by
their
production.
Counsel
for
the
intervenors
suggests
that
another
line
is
taken
when
the
information
is
voluntarily
provided
to
the
Crown
under
strict
confidential
cover.
Counsel
cites
two
cases
from
this
Court,
Electrohome
Limited
v.
Deputy
Minister
of
National
Revenue
for
Customs
and
Excise,
No.
T-2726-85,
January
31,
1986,
which
followed
the
position
of
the
Court
taken
in
Vanguard
Coatings
and
Chemicals
Ltd.
v.
M.N.R.,
[1986]
2
C.T.C.
139,
431;
86
D.T.C.
6342,
6552.
In
the
latter
case,
Rouleau,
J.
had
this
to
say:
In
this
case
the
applicants
maintain
that
they
are
being
treated
unfairly
by
virtue
of
the
Deputy
Minister’s
refusal
to
provide
them
with
the
confidential
information
as
requested.
That
argument
must
fail.
The
applicants
have
failed
to
provide
this
Court
with
any
evidence
of
unfair
treatment;
they
have
failed
to
produce
any
evidence
to
indicate
that
the
Deputy
Minister
may
have
used
or
been
provided
with
incorrect
information
in
his
investigations.
In
effect,
the
applicants
have
failed
to
provide
any
reason
as
to
why
I
should
reverse
the
decision
of
the
Deputy
Minister
except
that
they
want
the
confidential
information
in
order
to
ensure
that
the
Deputy
Minister
has
correctly
fulfilled
his
statutory
duty
in
determining
normal
value,
export
price
and
the
resultant
margin
of
dumping.
In
my
view,
the
applicants
have
no
statutory
nor
common
law
right
to
the
confidential
information
nor
do
they
have
the
right
to
force
the
Deputy
Minister
to
solicit
their
assistance
in
the
performance
of
his
statutory
duty.
I
am
not
satisfied
that
the
Deputy
Minister's
refusal
to
disclose
the
confidential
information
in
his
possession
is
a
breach
of
any
common
law
duty
of
fairness.
On
the
factual
situation
facing
the
Court,
counsel
for
the
intervenors
conclude
that
disclosure
would
undermine
the
willingness
of
members
of
an
industry
in
supplying
proprietary
information
if
there
is
a
perceived
risk
of
prejudicing
their
competitive
position.
Further,
the
requirements
imposed
on
the
Crown
to
apply
properly
the
rules
relating
to
reasonable
commissions,
discounts
and
fair
pricing
generally
under
the
Income
Tax
Act
would
be
frustrated
if
the
voluntary
participation
of
the
members
of
a
particular
industry
was
thus
inhibited.
There
is
more
case
law
on
this
subject.
In
AMP
of
Canada
Ltd.
v.
The
Queen,
[1987]
1
C.T.C.
256;
87
D.T.C.
5157,
the
case
for
the
Crown
hinged
on
comparisons
it
had
made
between
the
profits
of
the
taxpayer
and
those
of
its
competitors.
The
taxpayer
then
applied
for
the
production
of
the
competitors'
financial
statements
to
which
one
of
the
competitors,
a
private
company,
objected.
Collier,
J.
ruled
that
the
taxpayer
had
brought
himself
within
the
principle
set
down
in
the
Huron
Steel
case,
supra,
and,
subject
to
conditions
of
confidentiality,
ordered
the
production.
The
disclosure
of
confidential
information
has
of
course
been
the
subject
of
debate
under
other
federal
statutes.
Under
the
Canadian
International
Trade
Tribunal
Act,
R.S.C.
1965,
c.
47
(4th
Supp.),
when
dealing
with
alleged
dumping
practices,
a
complainant
must
of
necessity
provide
proprietary
information
to
the
tribunal
and
this
information
would
normally
become
available
to
all
other
complainants
who
are
in
competition
with
him.
This
poses
a
dilemma
to
all
the
complainants.
They
cannot
make
their
case
without
disclosure
and
they
cannot
disclose
without
risk
to
their
competitive
positions.
The
way
out
of
this
impasse,
under
section
45
of
the
Act,
is
to
limit
access
to
such
information
to
counsel
for
the
parties
on
their
filing
with
the
tribunal
their
solemn
undertaking
not
to
disclose
to
anyone
else.
Disclosure,
however,
cannot
be
made
in
any
event
to
any
person
who
is
a
director,
officer
or
employee
of
a
complainant.
The
same
kind
of
conflict
arises
under
the
Access
to
Information
Act,
S.C.
1980-81-82-83
c.
111,
Sch
I.
In
Maislin
Industries
Ltd.
v.
Minister
for
Industry,
Trade
and
Commerce,
10
D.L.R.
(4th)
417,
the
Associate
Chief
Justice
of
this
Court
faced
the
first
third
party
review
of
disclosure
under
subsection
44(1)
of
the
Act
and
discussed
at
length
the
balancing
act
which
must
be
maintained
and
the
various
statutory
formulae
to
achieve
it.
His
Lordship
noted
particularly
the
provisions
of
subsection
2(1)
of
the
Act
which
says:
2.(1)
The
purpose
of
this
Act
is
to
extend
the
present
laws
of
Canada
to
provide
a
right
of
access
to
information
in
records
under
the
control
of
a
government
institution
in
accordance
with
the
principles
that
government
information
should
be
available
to
the
public,
that
necessary
exceptions
to
the
right
of
access
should
be
limited
and
specific
and
that
decisions
on
the
disclosure
of
government
information
should
be
reviewed
independently
of
government.
It
is
therefore
only
by
exception
that
disclosure
will
be
refused
and
the
field
of
exception
is
covered
by
subsection
20(1)
of
the
Act
which
states:
20.(1)
Subject
to
this
section,
the
head
of
a
government
institution
shall
refuse
to
disclose
any
record
under
this
Act
that
contains
(a)
trade
secrets
of
a
third
party;
(b)
financial,
commercial,
scientific
or
technical
information
that
is
confidential
information
supplied
to
a
government
institution
by
a
third
party
and
is
treated
consistently
in
a
confidential
manner
by
the
third
party;
(c)
information
the
disclosure
of
which
could
reasonably
be
expected
to
result
in
material
financial
loss
or
gain
to,
or
could
reasonably
be
expected
to
prejudice
the
competitive
position
of
a
third
party;
or
(d)
information
the
disclosure
of
which
could
reasonably
be
expected
to
interfere
with
contractual
or
other
negotiations
of
a
third
party.
The
statute
also
provides
that
any
unresolved
issue
through
the
normal
processes
of
the
Act
may
be
the
subject
of
a
complaint
before
the
Federal
Court
under
section
41.
Further,
section
47
instructs
the
Court
to
take
every
reasonable
precaution,
including
ex
parte
representation
and
in
camera
hearings
to
avoid
disclosure
while
the
merits
are
debated.
It
was
under
this
wide
statutory
umbrella
that
the
Associate
Chief
Justice
could
state
at
page
419
of
the
Maislin
decision:
Since
this
is
the
first
motion
of
this
nature,
there
were
several
procedural
questions
to
be
resolved,
and
I
heard
counsel
at
some
length
on
the
matter
of
directions,
including
in
camera
hearings,
burden
of
proof
and
cross
examination
on
affidavits
filed.
On
the
subject
of
closed
hearings,
proceedings
in
our
courts
must
take
place
in
full
public
view
and
in
the
presence
of
all
parties.
Exceptions
to
this
principle
occur
from
time
to
time,
but
must
be
kept
to
the
minimum
of
absolute
necessity.
Even
then,
directions
should
be
such
as
to
safeguard
the
public
interest
in
the
administration
of
justice,
and
the
rights
of
any
parties
not
permitted
to
participate.
In
applications
under
these
access
to
information
statutes,
the
issue
is
confidentiality,
and
obviously
to
conduct
them
in
public
view
pre-empts
the
final
decision.
For
the
present,
therefore,
there
does
not
seem
to
be
any
alternative
but
to
restrict
attendance
to
counsel
for
the
parties.
A
similar
dilemma
arises
with
the
question
of
access
to
the
disputed
documents
by
counsel
(in
this
case
for
Hunter).
Obviously,
counsel
cannot
be
expected
to
argue
intelligently
on
the
nature
of
a
document
he
has
not
seen,
yet
to
provide
unrestricted
access
could
predetermine
the
central
issue.
This
determination
will
vary
with
the
circumstances
of
each
case,
but
here,
having
examined
the
full
text
of
the
report,
I
considered
it
appropriate
to
accept
counsel's
undertaking
of
nondisclosure,
even
to
his
client,
and
to
allow
him
access
to
the
disputed
portion
solely
for
the
purpose
of
argument.
Proceedings
involving
intellectual
property
law,
as
in
patent
infringement
cases,
have
also
provoked
innumerable
instances
where
discovery
of
confidential
documents
has
been
debated.
The
experience
shows
that
such
documents
have
more
often
been
initially
examined
by
the
Court
and
if
found
relevant
to
the
issues,
have
been
ordered
produced
but
nevertheless
with
limited
access
to
specified
persons
and
with
a
confidentiality
order
against
all
of
them.
Lead
counsel
for
the
intervenors
at
this
current
hearing,
realizing
no
doubt
that
the
plaintiff
had
the
burden
of
rebutting
the
Crown's
assumption
as
to
industry
averages
on
commissions
and
discounts,
suggested
in
argument
that
it
was
not
open
to
the
Crown
to
use
the
Thomson
Report
in
making
its
assessment.
There
is
an
ingenuous
submission
for
which
counsel
finds
support
in
the
case
of
Slavutych
v.
Baker,
a
Supreme
Court
of
Canada
decision
reported
at
55
D.L.R.
(3d)
224,
where
a
confidential
document
provided
by
a
professor
with
respect
to
a
colleague's
rating
for
tenure,
was
later
used
by
the
institution's
authorities
to
dismiss
the
same
professor.
Spence,
J.,
on
behalf
of
the
Court,
found
that
no
charge
could
be
laid
based
on
that
document.
Counsel
for
the
intervenors,
by
analogy,
then
urges
me
to
conclude
that
information
provided
under
the
strictest
confidence
could
not
later
be
used
as
grounds
for
reassessment
against
the
plaintiff.
Findings
Although
the
foregoing
does
not
exhaust
the
field
of
statutory
provisions
and
judicial
comments
relating
to
the
disclosure
of
confidential
information,
it
does,
in
my
view,
establish
how
and
under
what
circumstances
confidential
information
will
be
disclosed.
As
noted
earlier,
a
Court
faces
a
veritable
impasse
in
attempting
to
respect
the
privacy
of
confidential
information
on
the
one
hand
and
on
the
other,
in
finding
some
means
of
securing
the
ends
of
justice.
In
the
case
before
me,
the
Crown's
position
in
assessing
the
plaintiff
is
based
on
the
assumption
of
what
is
the
industry-wide
average
of
commissions
and
discounts
allowed
to
buyers.
On
discovery,
the
Crown
acknowledges
that
this
assumption
is
based
on
the
Thomson
Report.
The
plaintiff,
however,
is
aware
that
it
has
the
onus
of
rebutting
the
Crown's
assumption
and
claims
of
course
that
it
cannot
do
so
unless
the
detailed
data
on
which
the
conclusions
in
the
Report
are
reached
are
made
available.
The
plaintiff
wishes
to
investigate
whether
or
not
the
analyses
made
in
the
Report
cover
comparables
or,
as
specifically
stated
in
the
affidavit
evidence,
whether
"the
data
used
to
arrive
at
the
conclusion
in
the
report
is
comparable
to
the
facts
in
the
plaintiff's
case".
There
is
no
doubt
that
in
accordance
with
contemporary
rules
governing
discovery,
such
background
information,
absent
the
issue
of
confidentiality,
would
be
produced.
In
such
circumstances,
the
sole
issue
remains
to
balance
the
needs
of
the
plaintiff
to
attempt
to
prove
his
case
with
the
needs
of
the
intervenors
to
protect
the
confidentiality
of
the
information
which
they
have
voluntarily
submitted.
A
review
of
the
case
law
dealing
with
discovery
of
private
documents,
together
with
specific
provisions
in
some
statutes
I
have
cited
dealing
with
confidentiality
processes,
indicate
clearly
to
what
extent
the
law
has
come
to
terms
with
this
kind
of
dilemma.
It
has
resolved
it
in
different
ways
but
I
can
only
conclude
that,
in
attempting
to
secure
the
ends
of
justice
in
the
face
of
the
mutually
exclusive
principles
of
confidentiality
and
disclosure,
it
simply
adopted
a
policy
of
damage
control.
On
the
facts
before
me,
it
is
very
important
to
remember
the
kind
of
assurances
that
both
the
Thomson
people
and
the
Crown
provided
to
the
intervenors
when
proprietary
information
was
voluntarily
provided.
Those
undertakings
cannot
be
taken
lightly
and
no
doubt,
any
form
of
disclosure
at
this
time
would
create
stress
among
participants
should
similar
cooperation
be
requested
in
the
future.
On
the
other
hand,
I
should
on
balance
find
that
the
interests
of
justice,
in
the
light
of
the
narrow
manoeuvring
room
available
to
a
plaintiff
in
challenging
an
assessment
under
the
Income
Tax
Act,
require
that
disclosure
be
ordered.
Such
disclosure,
obviously,
would
be
subject
to
the
strictest
possible
terms
of
confidentiality
and
would
be
in
accordance
generally
with
those
already
circulated
to
various
intervenors
subsequent
to
the
January
21,
1991
hearing
before
Walsh,
D.J.
and
which
might
have
provoked
some
degree
of
grudging
consent
among
some
of
them.
The
experience
to
date
is
that
restricted
disclosure
and
a
formal
protective
order
have
minimized,
if
not
eliminated,
the
risk
of
prejudice.
I
appreciate
that
in
the
eyes
of
the
intervenors,
the
perceived
risk
is
always
there
but
that
is
the
best
a
Court
can
do
in
all
the
circumstances
of
the
case.
The
January
21,
1991
draft
of
an
order
should
provide
the
kind
of
assurances
usually
given
in
similar
cases.
The
plaintiff
has
requested
one
change
to
that
draft,
namely
that
disclosure,
subject
to
undertakings,
be
authorized
to
two
counsel.
I
see
no
objection
to
this
but
nevertheless,
I
should
limit
disclosure
to
four
people,
namely
two
counsel
and
two
expert
advisors.
This
excludes
support
staff
for
any
of
them.
The
plaintiff
and
the
Crown
are
invited
to
submit
a
draft
order
in
accordance
with
the
foregoing
for
my
endorsement.
Costs

the
cause.
Motion
granted.
