Isaac
CJ
.:
This
is
an
appeal
from
a
judgment
of
the
Tax
Court
of
Canada
(now
reported
at
92
D.T.C.
1898)
which
allowed
the
appeal
of
Dean
Ast,
in
his
capacity
as
executor
of
the
estate
of
Harold
Ast,
deceased,
from
an
assessment
under
the
Income
Tax
Act,
S.C.
1970-71-72,
c.63,
as
amended,
(“the
Act’)
for
the
1989
taxation
year,
and
remitted
the
matter
to
the
Minister
of
National
Revenue
(“the
Minister”)
for
reconsideration
and
reassessment
on
the
basis
that
the
claim
for
a
capital
gains
deduction
from
“other
property”
pursuant
to
subsection
110.6(2.1)
of
the
Act
in
the
amount
of
$66,582.11
in
respect
of
the
disposition
of
qualified
small
business
corporation
shares
was
properly
claimed
in
the
1989
taxation
year.
Background
On
23
September
1987,
Harold
Ast
sold
all
of
the
shares
in
his
pharmacy
business
to
his
son
for
$110,000
cash,
paid
in
full
as
of
that
date.
In
his
return
for
the
1987
taxation
year,
Harold
Ast
claimed,
in
respect
of
that
disposition,
the
maximum
allowable
capital
gains
deduction
as
“other
property”
under
the
Act
as
it
stood
at
the
time,
which
for
him
was
$49,936.33.
On
13
September
1988,
the
Act
was
amended
by
the
addition
of
subsection
110.6(2.1),
which
provided
for
an
enhanced
capital
gains
deduction.
.
The
new
provision
increased
the
maximum
exemption
available
for
capital
gains
on
dispositions
of
qualified
small
business
corporation
shares.
Harold
Ast
died
on
15
October
1989;
the
respondent,
Dean
Ast,
was
named
executor
of
his
estate.
Harold
Ast’s
terminal
return
was
prepared
by
his
accountant,
Gordon
Dillon.
In
the
return,
the
estate
claimed
the
enhanced
deduction,
$66,582.11,
in
respect
of
the
September
1987
sale
of
pharmacy
shares.
The
respondent
contends
that
the
estate
was
entitled
to
claim
the
capital
gains
deduction
in
respect
of
that
share
disposition
because
it
constituted
a
disposition
of
qualified
small
business
corporation
shares
“in
the
year
or
a
preceding
taxation
year
and
after
June
17,
1987”.
The
Minister
of
National
Revenue
rejected
the
respondent’s
claim
to
the
enhanced
deduction
and
reduced
the
claim
to
$1.
Legislative
framework
In
1988,
section
81
of
the
amending
legislation
which
enacted
subsection
110.6(2.1)
read,
in
part:
(6)
Section
110.6
is
further
amended
by
adding
thereto,
immediately
after
subsection
(2)
thereof,
the
following
subsection:
(2.1)
In
computing
the
taxable
income
for
a
taxation
year
of
an
individual
(other
than
a
trust)
who
was
resident
in
Canada
throughout
the
year
and
who
disposed
of
a
share
of
a
corporation
in
the
year
or
a
preceding
taxation
year
and
after
June
17,
1987
that,
at
the
time
of
disposition,
was
a
qualified
small
business
corporation
share
of
the
individual,
there
may
be
deducted
such
amount
as
he
may
claim
not
exceeding
the
least
of
(a)
the
amount,
if
any,
by
which
$375,000
exceeds
the
total
of
(i)
the
aggregate
of
all
amounts
each
of
which
is
an
amount
deducted
by
the
individual
under
this
section
in
computing
his
taxable
income
for
a
preceding
taxation
year,
(ii)
where
the
taxation
year
ended
after
1987,
the
amount
determined
under
subparagraph
(2)(a)(iii)
in
respect
of
the
individual
for
the
year,
and
(iii)
where
the
taxation
year
ended
after
1989,
the
amount
determined
under
subparagraph
(2)(a)(iii)
in
respect
of
the
individual
for
the
year;
(b)
the
amount
if
any,
by
which
his
cumulative
gains
limit
at
the
end
of
the
year
exceeds
the
amount
deducted
under
subsection
(2)
in
computing
his
taxable
income
for
the
year;
(c)
the
amount,
if
any,
by
which
his
annual
gains
limit
for
the
year
exceeds
the
amount
deducted
under
subsection
(2)
in
computing
his
taxable
income
for
the
year;
and
(d)
the
amount
that
would
be
determined
in
respect
of
the
individual
for
the
year
under
subparagraph
3(b)
(other
than
an
amount
included
in
respect
of
the
individual
under
paragraph
(2)(d)
in
respect
of
capital
gains
and
capital
losses
if
the
only
properties
referred
to
in
that
paragraph
were
qualified
small
business
corporation
shares
disposed
of
by
him
after
June
17,
1987.
(17)
Subsections
(1)
to
(10),
(12),
(13),
(15)
and
(16)
are
applicable
to
the
1988
and
subsequent
taxation
years
except
that
(b)
the
definition
“qualified
small
business
corporation
share”
in
subsection
110.6(1)
of
the
said
Act,
as
enacted
by
subsection
(4),
and
subsection
110.6(14)
of
the
said
Act,
as
enacted
by
subsection
(16),
are
applicable
with
respect
to
dispositions
of
shares
after
June
17,
1987;
...
[Emphasis
added.]
This
appeal,
then,
turns
upon
the
interpretation
of
subsection
110.6(2.1)
with
respect
to
the
“notch”
period
between
17
June
1987
and
the
beginning
of
1988.
The
principal
subsection
of
the
amending
legislation,
subsection
81(17),
makes
the
enhanced
deduction
“applicable
to
the
1988
and
subsequent
taxation
years”,
whereas
subsection
110.6(2.1)
appears
to
make
the
enhanced
deduction
available
for
transactions
occurring
“in
the
year
or
a
preceding
taxation
year
and
after
June
17,
1987”.
Paragraph
39(l)(a)
of
the
Act
defines
capital
gain
in
a
taxation
year
as
the
amount
of
capital
gain
realized
in
that
year.
Paragraph
39(l)(a)
reads:
39.(1)
For
the
purposes
of
this
Act,
(a)
a
taxpayer’s
capital
gain
for
a
taxation
year
from
the
disposition
of
any
property
is
his
gain
for
the
year
determined
under
this
subdivision
(to
the
extent
of
the
amount
thereof
that
would
not,
if
section
3
were
read
without
reference
to
the
expression
“other
than
a
taxable
capital
gain
from
the
disposition
of
a
property”
in
paragraph
(a)
thereof,
be
included
in
computing
his
income
for
the
year
or
any
other
taxation
year)
from
the
disposition
of
any
property
of
the
taxpayer...
Decision
of
the
Tax
Court
The
Tax
Court
Judge
concluded
that
subsection
110.6(2.1)
should
not
be
narrowly
construed.
In
the
absence
of
language
linking
the
provisions
respecting
share
dispositions
taking
place
“after
June
17,
1987”
to
reserves
carried
over,
she
held
that
the
enhanced
deduction
also
applied
to
non-re-
serve
transactions
occurring
in
1987
after
June
17.
Although
there
was
evidence
that
Harold
Ast
had
claimed
the
deduction
for
the
same
disposition
in
the
1987
return,
the
Tax
Court
Judge
concluded
that
the
provision
was
ambiguous,
and
she
resorted
to
the
presumption
in
favour
of
the
taxpayer
to
find
that
the
September
1987
share
disposition
could
give
rise
to
the
claim
for
the
enhanced
capital
gains
deduction
in
his
terminal
return
in
1989.
Analysis
In
oral
argument,
counsel
for
the
appellant
and
the
respondent
agreed
that
the
provisions
of
subsection
110.6(2.1)
and
its
enacting
legislation
are
ambiguous
with
respect
to
transactions
occurring
during
the
“notch”
period.
Subsection
81(17)
of
the
enabling
legislation
provides
that
subsection
110.6(2.1)
of
the
Act
is
applicable
to
1988
and
subsequent
taxation
years.
The
appellant
contends
that
the
reference
in
paragraph
81(17)(b)
of
the
enabling
legislation
to
share
dispositions
occurring
“after
June
17,
1987”
has
the
effect
of
allowing
such
transactions
to
qualify
for
the
enhanced
capital
gains
deduction
only
insofar
as
reserves
are
carried
over
into
1988
or
subsequent
taxation
years.
The
appellant
points
out
that
for
the
1987
taxation
year,
Harold
Ast
had
claimed
the
full
capital
gains
deduction,
$49,936.33,
as
a
deduction
in
respect
of
“other
capital
property”
in
respect
of
the
September
1987
transaction.
In
the
1989
terminal
return
of
Harold
Ast,
however,
the
estate
claimed
the
full
amount
of
the
enhanced
deduction,
$66,666.67,
in
respect
of
a
disposition
of
“qualified
small
business
corporation
shares”.
.
Moreover,
in
Part
5
of
the
1989
return,
“Calculation
of
Capital
Gains
Deduction
-
Other
Property”,
the
amount
reported
as
“capital
gains
deduction
claimed
in
1987”
was
zero.
The
appellant
argues
that
the
accountant
who
prepared
the
1989
return
“moved”
the
deduction
originally
claimed
in
1987
in
respect
of
the
September
1987
share
disposition
from
the
category
“other
property”
to
the
category
“qualified
small
business
corporation
shares”
in
order
to
claim
the
1989
capital
gain
for
the
real
estate
dispositions
as
“other
property”.
The
Ast
estate
then
claimed
the
full
enhanced
capital
gains
deduction
in
respect
of
the
same
1987
transaction
for
which
the
capital
gains
deduction
had
been
allowed
in
1987.
The
appellant
argues
further
that,
since
no
reserves
from
the
September
1987
transaction
were
carried
over
into
1989,
Harold
Ast
received
no
capital
gain
in
respect
of
that
transaction
in
1989
and
was
therefore
his
estate
was
not
entitled
to
claim
the
capital
gains
deduction
in
that
year.
To
conclude
otherwise,
the
appellant
says,
would
amount
to
allowing
the
taxpayer
to
claim
retroactively
in
1989
the
deduction
in
respect
of
a
transaction
for
which
the
benefit
was
received,
and
the
full
deduction
allowed,
in
1987.
The
appellant
cites
the
Technical
Notes
prepared
by
the
Department
of
Finance
in
support
of
its
contention
that
the
enhanced
deduction
is
available
in
respect
of
a
“notch”
period
transaction
only
insofar
as
reserves
from
that
transaction
are
carried
over
into
1988
or
a
subsequent
taxation
year.
The
technical
notes
read
as
follows:
110.6(2.1).
1988
TN--New
subsection
110.6(2.1)
of
the
Act
provides
for
special
increased
capital
gains
exemption
for
individuals
(other
than
trusts)
for
a
taxation
year
in
respect
of
net
taxable
capital
gains
realized
on
the
disposition
of
qualified
small
business
corporation
shares
in
the
year
or
in
a
preceding
year
and
after
June
17,
1987.
The
deduction
permitted
under
subsection
110.6(2.1)
in
respect
of
qualified
small
business
corporation
shares
is
equal
to
the
least
of
four
amounts:
(4)
The
individual’s
net
taxable
capital
gains
for
the
year
from
dispositions
of
qualified
small
business
corporation
[sic]
shares
after
June
17,
1987,
less
any
such
amount
accounted
for
in
paragraph
110.6(2)(d)
of
the
Act.
This
provisions
permits
reserves
from
prior
years'
dispositions
of
qualified
small
business
corporation
shares
to
qualify
for
this
special
capital
gains
exemption
if
the
shares
were
disposed
of
after
June
17,
1987.
It
also
prevents
a
double
benefit
where
the
qualified
small
business
corporation
shares
are
also
qualified
farm
property-that
is,
shares
of
the
capital
stock
of
a
family
corporation.
[Emphasis
added.]
On
the
other
hand,
the
respondent
argues
that
the
Tax
Court
Judge
was
correct
to
conclude
that
the
enhanced
capital
gains
deduction
is
available
in
respect
of
all
“notch”
period
transactions.
The
respondent
argues
further
that
the
references
to
share
dispositions
“after
June
17,
1987”
make
the
legislation
specifically
retroactive
so
that
the
enhanced
deduction
is
available
in
respect
of
all
transactions
occurring
after
that
date,
whether
or
not
reserves
are
carried
over
into
subsequent
years.
Furthermore,
the
respondent
says
that
the
restrictive
interpretation
advanced
by
the
appellant
is
not
supported
by
any
statutory
language
referring
to
reserves
carried
over
into
subsequent
years.
Moreover,
so
the
argument
ran,
any
ambiguity
in
the
legislation
should
be
interpreted
in
favour
of
the
respondent
taxpayer.
The
respondent
contends
further
that
the
different
categorization
of
the
1987
capital
gain
in
the
1987
and
1989
returns
is
explained
by
the
1988
enactment
of
subsection
110.6(2.1).
He
says
that
the
September
1987
share
disposition
was
properly
characterized
according
to
1987
law
as
a
capital
gain
in
respect
of
“other
property”.
However,
he
also
says
that
because
the
enhanced
capital
gains
deduction
enacted
in
1988
had
an
explicitly
retroactive
effect,
in
1989
the
accountant
properly
took
advantage
of
the
new
legislation
by
“moving”
the
1987
capital
gains
deduction
to
the
category
“qualified
small
business
corporation
shares”,
where
the
maximum
available
was
now
$66,666.67,
in
order
to
allow
for
a
claim
for
a
1989
deduction
for
capital
gains
realized
in
1989
in
respect
of
real
property.
I
am
in
respectful
agreement
with
the
learned
Tax
Court
Judge
and
with
the
respondent
that
the
effect
of
subsection
110.6(2.1)
and
the
amending
legislation
with
respect
to
transactions
during
the
“notch”
period
is
not
clear.
On
the
one
hand,
the
provision
on
its
face
contains
no
reference
to
the
mode
or
timing
of
payment
that
would
support
the
appellant’s
contention
that
the
“notch”
period
provisions
are
intended
to
include
only
those
1987
transactions
for
which
a
reserve
is
carried
over
into
a
subsequent
year.
On
the
other
hand,
the
interpretation
advanced
by
the
respondent
is
contrary
to
the
statutory
definition
of
“capital
gain”
in
subsection
39(1)
of
the
Act.
Subsection
39(1)
defines
capital
gain
as
a
capital
gain
realized
in
the
particular
taxation
year.
Furthermore,
according
to
the
respondent’s
interpretation,
subsection
110.6(2.1)
would
allow
for
“double-dipping”
in
that
it
would
allow
taxpayers
to
claim
the
enhanced
deduction
in
subsequent
years
for
1987
transactions
for
which
they
have
already
claimed,
and
received,
the
full
benefit
of
the
1987
capital
gains
deduction.
Indeed,
this
is
exactly
what
the
respondent
attempts
to
do
in
this
case.
Taxation
statutes
should
be
construed
according
to
the
ordinary
rules
of
statutory
interpretation.
Thus
recourse
to
the
residual
presumption
in
favour
of
the
taxpayer
is
necessary
only
if
a
reasonable
doubt
about
the
meaning
of
the
taxing
provision
cannot
be
resolved
by
the
ordinary
rules
of
statutory
interpretation.
The
approach
to
be
taken
to
the
interpretation
of
taxing
statutes
was
laid
down
by
Estey
J.
in
Stubart
v.
Minister
of
National
Revenue,
[1984]
1
S.C.R.
536
(S.C.C.),
quoting
Driedger
in
The
Construction
of
Statutes:
Today
there
is
only
one
principle
or
approach,
namely,
the
words
of
an
Act
are
to
be
read
in
their
entire
context
and
in
their
grammatical
and
ordinary
sense
harmoniously
with
the
scheme
of
the
Act,
the
object
of
the
Act,
and
the
intention
of
Parliament.
Purposive
interpretation
cannot
override
the
statutory
language
selected
by
Parliament
if
its
meaning
and
application
are
clear
and
plain.
However,
as
I
have
already
noted,
the
language
of
subsection
110.6(2.1)
does
not
make
clear
how
the
provisions
affect
share
dispositions
occurring
during
the
“notch”
period.
It
would
be
unreasonable,
in
my
respectful
view,
to
conclude
that
Parliament
intended
to
allow
taxpayers
to
claim
the
enhanced
capital
gains
deduction
in
any
or
every
subsequent
year
in
respect
of
share
dispositions
occurring
between
18
June
and
31
December
1987
when
the
capital
gains
deduction
had
already
been
fully
claimed
and
allowed
for
the
year
of
the
transaction.
The
interpretation
advanced
by
the
respondent
would
result
in
an
absurd
and
unreasonable
consequence
and
should
therefore
not
be
accepted.
As
Estey
J.
stated
in
Berardinelli
v.
Ontario
Housing
Corp.
(1978),
90
D.L.R.
(3d)
481
(S.C.C.):
Where
one
interpretation
can
be
placed
upon
a
statutory
provision
which
would
bring
about
a
more
workable
and
practical
result,
such
an
interpretation
should
be
preferred
if
the
words
invoked
by
the
Legislature
can
reasonably
bear
it.
Since
the
effect
of
subsection
110.6(2.1)
and
its
enacting
legislation
with
respect
to
share
dispositions
occurring
during
the
“notch”
period
is
not
made
clear
by
the
statutory
language,
the
intention
of
Parliament
may
be
illuminated
by
the
use
of
the
administrative
interpretation,
which
in
this
case
formed
part
of
the
legislative
context.
The
appellant’s
interpretation
of
the
reference
in
subsection
110.6(2.1)
to
transactions
taking
place
after
18
June
1987
is
supported
by
the
explanatory
notes
published
16
December
1987,
after
the
tabling
of
the
White
Paper
introducing
the
legislative
amendments
that
included
subsection
110.6(2.1),
but
well
before
the
legislation
was
passed
on
13
September
1988.
Neither
the
White
Paper
nor
the
explanatory
notes
were
in
evidence
in
this
appeal.
At
trial,
the
respondent’s
accountant,
Mr.
Dillon,
testified
that
the
White
Paper
informed
his
decision
to
claim
the
capital
gains
deduction
in
1987,
and
to
claim
the
enhanced
deduction
in
respect
of
the
same
transaction
in
1989.
In
argument
before
us,
counsel
for
the
appellant
pointed
out
that
at
trial
he
had
asked
that
the
White
Paper
be
tendered
in
evidence,
but
it
was
not.
The
commentary
of
the
Department
of
Finance
in
the
White
Paper
with
respect
to
subsection
110.6(2.1)
tends
to
support
the
interpretation
sug-
gested
by
the
appellant:
“Small
business
shares
will
be
eligible
for
the
$500,000
exemption,
effective
in
1988”.
In
the
explanatory
notes,
the
Department
made
more
explicit
its
view
that
the
enhanced
deduction
was
available
in
respect
of
1987
share
dispositions
occurring
after
17
June
1987
only
insofar
as
reserves
were
carried
over
into
subsequent
years.
The
explanatory
notes
respecting
this
question
read:
Capital
gains
from
dispositions
of
shares
of
small
business
corporations
that
are
being
included
in
income
after
1987
through
the
capital
gains
reserve
mechanism
will
be
eligible
for
the
$500,000
exemption
for
small
business
shares
where
the
shares
have
been
disposed
of
after
June
17,
1987.
A
capital
gain
reserve
brought
into
income
after
1987
in
respect
of
capital
gains
on
small
business
shares
disposed
of
before
June
18,
1987
will
qualify
for
the
$100,000
exemption
provided
for
other
property.
Administrative
interpretations
such
as
technical
notes
are
not
binding
on
the
courts,
but
they
are
entitled
to
weight,
and
may
constitute
an
important
factor
in
the
interpretation
of
statutes.
Technical
notes
are
widely
accepted
by
the
courts
as
aids
to
statutory
interpretation.
The
interpretive
weight
of
technical
notes
is
particularly
great
where,
at
the
time
an
amendment
was
before
it,
the
legislature
was
aware
of
a
particular
administrative
interpretation
of
the
amendment,
and
nonetheless
enacted
it.
In
Hard
v.
Quebec
(Deputy
Minister
of
Revenue),
(1977),
[1978]
1
S.C.R.
851
(S.C.C.),
de
Grandpré
J.
observed,
for
a
unanimous
Supreme
Court
of
Canada:
That
was
the
situation
in
1954
when
the
provincial
law
closely
modelled
on
the
federal
law
was
adopted.
At
that
time,
the
provincial
legislator
was
familiar
not
only
with
the
wording
of
s.36(l)
of
the
federal
Act
but
also,
undoubtedly,
with
the
administrative
interpretation
there,
which
was
to
the
effect
that
taxpayers
in
Mr.
Harel’s
situation
could
avail
themselves
of
the
averaging
provided
for
in
the
section.
Although
the
wording
of
s.45
of
the
provincial
Act
differs
somewhat
from
that
of
s.36(1)
of
the
federal
Act,
the
concept
is
the
same.
Consequently,
when
c.17
of
the
Statutes
of
Quebec,
1953-54
was
adopted,
the
administrative
interpretation
of
the
federal
Act
gave
it
a
colour
that
the
provincial
legislature
could
not
ignore....
..1
am
not
saying
that
the
administrative
interpretation
could
contradict
a
clear
legislative
text;
but
in
a
situation
such
as
I
have
just
outlined,
this
interpretation
has
real
weight
and,
in
case
of
doubt
about
the
meaning
of
the
legislation,
becomes
an
important
factor.
The
same
reasoning
applies
in
this
appeal.
Even
though
reserves
carried
over
from
1987
transactions
are
not
expressly
mentioned
in
subsection
110.6(2.1),
Parliament
was
aware
at
the
time
the
legislation
was
passed
that
the
Department
of
Finance
considered
the
enhanced
deduction
to
apply
to
1987
transactions
occurring
after
17
June
1987
only
in
respect
of
reserves
carried
over
into
subsequent
years.
Thus
Parliament
may
be
presumed
to
have
intended
the
effect
described
in
the
White
Paper,
and
more
particularly
in
the
explanatory
notes.
The
interpretation
advanced
by
the
appellant
is
therefore
preferable
to
that
advanced
by
the
respondent.
It
is
thus
unnecessary
to
resort
to
the
residual
presumption
in
favour
of
the
taxpayer.
Gonthier
J.
observed
for
the
Court
in
Corporation
Notre
Dame
de
Bon-Secours
v.
Communauté
Urbaine
de
Québec:
Two
comments
should
be
made
to
give
Estey
J.’s
observations
[in
Johns-
Manville
Canada
Inc.
v.
The
Queen,
[1985]
2
S.C.R.
46]
their
full
meaning:
first,
recourse
to
the
presumption
in
favour
of
the
taxpayer
is
indicated
when
a
court
is
forced
to
choose
between
two
valid
interpretations,
and
second,
this
presumption
is
clearly
residual
and
should
play
an
exceptional
part
in
the
interpretation
of
tax
legislation.
In
this
case,
the
two
interpretations
offered
by
the
parties
to
this
appeal
are
not
equally
valid.
While
the
interpretation
urged
by
the
respondent
would
lead
to
an
unreasonable
result,
the
interpretation
urged
by
the
appellant
is
consistent
with
the
language
of
subsections
110.6(2.1)
and
39(1)
of
the
Act,
and
is
supported
by
the
administrative
interpretation.
Thus
the
Tax
Court
Judge
erred
in
resorting
to
the
residual
presumption
in
favour
of
the
taxpayer.
All
of
the
capital
gains
from
the
September
1987
transaction
were
realized
in
1987.
Thus
the
capital
gain
deduction
available
in
respect
of
that
transaction
was
that
available
under
the
legislation
as
it
stood
in
1987.
Harold
Ast
claimed
and
received
the
benefit
of
that
deduction
in
1987;
his
estate
was
not
entitled
to
claim
again
in
1989,
in
respect
of
the
same
transaction,
the
enhanced
deduction
under
legislation
that
was
enacted
one
year
later.
Conclusion
For
all
of
these
reasons,
I
would
allow
this
appeal
with
costs,
set
aside
the
judgment
of
the
Tax
Court
judge,
and
restore
the
assessment
of
the
Minister.
Appeal
allowed.
