Reed
J.:—The
issue
in
this
case
is
whether
the
plaintiff
is
required
to
pay
interest
on
taxes
calculated
to
be
payable
with
respect
to
a
given
year,
as
a
result
of
a
capital
gain
in
that
year,
when
the
tax
payable
becomes
zero
as
the
result
of
the
application
of
a
capital
loss
arising
in
the
subsequent
year.
In
this
case
the
plaintiff
had
available
to
it
unused
deductions
and
tax
credits
which
could
have
been
used,
in
any
event,
to
offset
the
capital
gain
in
the
taxation
year,
to
bring
the
tax
payable
to
zero,
if
the
capital
loss
had
not
been
used
for
that
purpose.
The
plaintiff,
Connaught
Laboratories
Ltd.,
filed
a
tax
return
for
its
1981
taxation
year
showing
nil
tax
payable.
In
1985
the
Minister
reassessed
the
plaintiff’s
return
and
inter
alia
added
to
the
computation
of
its
taxable
income
for
1981
a
net
capital
gain
in
the
amount
of
$275,423.
Reassessment
on
this
basis
was
not
contested.
In
1982,
however
the
plaintiff
had
incurred
a
net
capital
loss
of
$273,452,
and
was
entitled
to
carry
this
amount
back
to
be
applied
against
the
1981
net
capital
gain.
At
the
request
of
the
plaintiff,
the
1985
reassessment
was
prepared
on
that
basis
and
this
resulted
in
nil
taxes
being
payable
with
respect
to
the
1981
year.
The
plaintiff
had
with
respect
to
the
1981
taxation
year,
undeclared
scientific
research
expenditures
available
of
approximately
$12,000,000.
It
had
available
unused
investment
tax
credits
of
approximately
$3,000,000.
The
former
can
be
carried
forward
indefinitely
and
applied
against
income
in
future
years.
The
latter,
while
also
being
able
to
be
carried
forward
to
reduce
taxes
payable
in
the
future,
are
accorded
a
limited
life
for
that
purpose.
In
addition,
capital
losses
have
even
less
flexibility;
they
can
only
be
applied
against
capital
gains
for
the
purpose
of
reducing
taxable
income.
Prudent
tax
planning,
therefore,
dictates
that
the
1982
capital
loss
should
be
applied
against
the
1981
capital
gain
and
that
investment
tax
credits
should
be
used,
to
the
extent
it
is
possible
to
do
so,
to
reduce
taxes
payable,
ahead
of
undeclared
scientific
research
expenditures.
This
is
what
the
taxpayer
chose
to
do.
Subsection
161(7)
of
the
Income
Tax
Act,
R.S.C.
1952,
c.
148
(am.
S.C.
1970-71-72,
c.
63
(the
"Act")
provides
for
the
payment
of
interest
with
respect
to
the
carryback
of
capital
losses:
Where
a
taxpayer
is
entitled
to
deduct
under
section
111
in
computing
his
taxable
income
for
a
taxation
year
an
amount
in
respect
of
a
loss
for
the
taxation
year
immediately
following
the
taxation
year
(hereinafter
in
this
subsection
referred
to
as
"the
loss
year"),
for
the
purpose
of
computing
interest
under
subsection
(1)
or
(2)
on
tax
or
a
part
or
instalment
of
tax
for
the
taxation
year
for
any
portion
of
the
period
in
respect
of
which
the
interest
is
payable
on
or
before
the
last
day
of
the
loss
year,
the
tax
payable
for
the
taxation
year
shall
be
deemed
to
be
the
amount
that
it
would
have
been
if
the
taxpayer
were
not
entitled
to
deduct
any
amount
under
section
111
in
respect
of
that
loss.
[Emphasis
added.]
The
Minister
argues
that
the
plaintiff
owes
interest
with
respect
to
the
1981
taxation
year,
on
the
$273,452
which
was
not
paid
in
that
year,
even
though
as
a
result
of
the
capital
losses
incurred
in
1982
the
tax
payable
for
1981
was
reduced
to
zero.
The
capital
loss
was
not
incurred
until
1982
and
taxes
were
payable
with
respect
to
the
$273,452
for
the
1981
taxation
year.
The
plaintiff
argues
that
had
there
been
no
capital
losses
in
1982
it
would
still
have
had
no
tax
payable
that
year
because
it
would
have
used
either
the
investment
tax
credits
or
the
undetected
scientific
research
expenditures
available
to
it,
to
reduce
its
tax
payable
to
zero.
I
do
not
interpret
subsection
161(7)
in
the
same
way
as
counsel
for
the
plaintiff.
I
interpret
the
term
"tax
payable",
upon
which
interest
is
to
be
paid,
pursuant
to
that
subsection,
as
referring
to
the
tax
payable
on
the
basis
of
the
particular
way
the
taxpayer
chooses
to
compute
its
taxable
income,
when
there
is
an
option
available,
in
this
regard.
I
do
not
interpret
that
subsection
as
referring
to
tax
which
might
have
been
payable
had
another
option
been
chosen.
Had
the
taxpayer
chosen
to
use
the
undetected
scientific
research
expenditures
or
its
investment
tax
credits
then
the
tax
payable
in
1981
would
have
been
zero.
The
taxpayer
would
also
however
not
have
had
the
amounts
so
used
available
to
set
off
against
future
income
or
future
taxes
payable.
Nor
would
the
taxpayer
have
been
able
to
use
the
capital
losses
which
it
incurred
in
1982,
to
lower
taxable
income,
unless
it
realized
capital
gains
in
the
future
against
which
to
set
them.
My
conclusion
is
that
the
wording
of
the
subsection
161(7)
requires
the
interest
payment
which
the
Minister
has
assessed.
I
find
no
ambiguity
in
the
wording.
Nor
do
I
find
it
offensive
to
the
purpose
or
the
objectives
of
the
Act
to
interpret
it
as
the
Minister
has
done
in
the
context
of
the
plaintiffs
situation.
I
do
not
think
the
reasons
in
Stubart
Investments
Ltd.

The
Queen,

are
of
assistance
to
the
plaintiff,
nor
are
the
excerpts
quoted
from
the
comments
of
Senator
Hayden
when
the
Bill,
which
added
subsection
161(7)
to
the
Income
Tax
Act,
was
being
debated
(Senate
Debates,
1st
Sess.,
22nd
Pari.,
1953-54,
page
594).
Applying
the
rules
of
statutory
interpretation
set
out
in
Stubart
leads
to
the
conclusion
respecting
the
interpretation
of
subsection
161(7)
which
I
have
set
out
above.
Senator
Hayden
described
the
provision
as
being
intended
to
cover
the
situation
where
a
taxpayer
ignores
payment
of
taxes
for
one
year
in
anticipation
of
a
capital
loss
in
the
second.
He
described
the
provisions
as
being
intended
to
cover
the
situation
where
a
taxpayer
in
the
taxation
year
in
question
makes
a
profit.
The
Senator’s
comments
were
designed
to
illustrate
in
a
general
way
the
type
of
situation
which
the
provisions
were
intended
to
cover
but
those
comments
were
not
intended
to
be
an
exhaustive
description
of
the
operation
of
the
provisions.
Indeed,
the
Senator’s
comments
cannot
take
precedence
over
the
clear
words
of
the
subsection.

…
The
courts
must
deal
with
what
the
taxpayer
actually
did
and
not
what
he
might
have
done....
This
principle,
I
believe,
can
also
apply
to
what
a
taxpayer
did
not
do
and
not
what
he
might
have
done.
Counsel
for
the
plaintiff
drew
my
attention
to
a
technical
interpretation
letter,
dated
June
1991,
issued
by
Revenue
Canada,
which
states
that
with
respect
to
the
facts
described
therein,
it
is
departmental
practice
not
to
charge
interest
under
subsection
161(1)
of
the
Act.
The
facts
describe
a
situation
in
which
in
year
one,
the
taxpayer
had
a
taxable
capital
gain
of
$1,000
and
non-
capital
losses
of
$1,000.
The
losses
were
applied
against
the
gain
to
result
in
nil
taxable
income
for
the
year.
In
year
two,
the
taxpayer
suffered
a
taxable
capital
loss
of
$
1,000
and
therefore
wished
to
have
that
applied
against
the
taxable
capital
gain
of
the
previous
year,
retaining
the
non-capital
losses
of
that
year
to
be
applied
against
future
years’
income.
The
letter
states
that
the
department
allows
such
a
refiling
by
the
taxpayer
and
that
interest
is
not
charged
with
respect
to
the
capital
gain
of
year
one
because
no
tax
was
payable
under
either
the
original
or
the
amended
return.
That
fact
situation
is
different
from
the
present
one.
In
year
one,
on
the
facts
described
by
the
letter,
the
capital
gain
was
declared
and
no
tax
was
payable
because
of
non-capital
losses
incurred
by
the
taxpayer.
Thus
when
the
amended
return
was
filed
it
was
merely
a
matter
of
substituting
one
type
of
loss
for
another-the
taxable
income
remained
nil.
In
the
present
case
there
were
taxes
payable
at
the
end
of
year
one,
as
a
result
of
the
undeclared
taxable
capital
gain
of
that
year.
In
the
present
situation,
had
the
taxpayer
declared
the
taxable
capital
gain
in
1981
and
offset
against
it
the
scientific
research
expenditures
and
unused
investment
tax
credits,
it
may
be
that
the
department
would
have
allowed
the
substitution
of
the
subsequent
capital
loss
in
1982
for
those
expenditures
and
credits.
But
that
is
not
what
occurred.
This
is
not
a
situation
where
there
were
no
taxes
payable
at
year
end-taxes
were
payable
as
a
result
of
the
undeclared
capital
gain.
I
do
not
think
the
two
fact
situations
are
comparable.
And,
in
any
event,
a
departmental
interpretation
letter
cannot
alter
the
unambiguous
terms
of
a
provision
of
the
Act.
For
the
reasons
given
the
plaintiff’s
claim
must
be
dismissed,
except
for
the
difference
between
$313,135
and
$273,452
($39,683)
which
I
have
not
referred
to
in
detail
because
I
understood
both
counsel
to
agree
that
that
adjustment
must
be
made.
Appeal
dismissed.
