Reed,
J:—This
action
concerns
the
treatment
of
interest
expense
under
paragraph
20(l)(c)
of
the
Income
Tax
Act,
SC
1970-71-72,
c
63
as
amended.
The
specific
issue
is
whether
a
taxpayer
can
account
for
interest
expense
on
a
cash
basis
when
he
accounts
for
the
rest
of
his
income
for
tax
purposes
on
an
accrual
basis
and
when
his
accounting
for
corporate
financial
reporting
purposes
is
on
the
accrual
basis.
The
facts
are
not
in
dispute.
The
defendant’s
mine
commenced
production
in
commercial
quantities
in
March,
1971,
with
the
result
that
the
three-year
period
within
which
it
could
earn
income
exempt
from
tax
pursuant
to
Income
Tax
Application
Rule
28(1)
commenced
at
that
time.
Accordingly,
had
the
taxpayer
accounted
for
interest
expense
on
an
accrual
basis
for
tax
purposes,
it
would
not
have
lowered
in
any
way
its
taxable
income
for
those
years.
During
all
relevant
periods,
the
defendant
accounted
for
interest
expense
on
an
accrual
basis
in
its
financial
statements,
however
in
computing
income
for
tax
purposes
interest
expenses
were
accounted
for
when
actually
paid.
As
a
result,
reassessments
were
issued
by
the
Minister
of
National
Revenue
for
the
fiscal
periods
ending
August
31,
1973,
December
31,
1973,
December
31,
1974
and
December
31,
1975.
The
defendant
appealed
these
reassessments
to
the
Tax
Review
Board
and
that
board
allowed
its
appeal
by
judgment
dated
April
22,
1981.
The
appeals
with
respect
to
the
1973
and
1974
taxation
years
were
dropped
at
trial,
these
having
been
nil
assessments.
Thus
only
the
assessment
respecting
the
1975
taxation
year
is
still
in
dispute.
The
first
question
is
whether
there
must
be
an
identity
of
method
between
the
taxpayer’s
accounting
for
tax
purposes
and
his
accounting
for
corporate
financial
reporting
purposes
except,
of
course,
when
specifically
otherwise
allowed
by
the
Act.
The
Minister
argues
that
this
must
be
so.
I
find
this
argument
miscast.
It
seems
to
me
that
it
has
long
been
accepted
that
different
methods
of
accounting
are
used
for
different
purposes.
The
method
will
vary
with
the
purpose
for
which
the
financial
statements
are
being
prepared.
Counsel
for
the
defendant
referred
me
to
an
article
by
B
L
Arnold
entitled
“Conformity
Between
Financial
Statements
and
Tax
Accounting”,
(1981)
29
Can
Tax
L
476.
He
also
relied
on
the
decision
in
Oxford
Shopping
Centres
v
The
Queen,
[1980]
CTC
7;
79
DTC
5458.
I
might
also
refer
to
a
passage
in
Scace,
The
Income
Tax
Law
of
Canada
(4th
Ed
1981)
at
72:
It
must
be
stressed,
however
that
while
accounting
principles
are
the
basis
of
the
computation
of
profit
for
tax
purposes,
they
are
not
always
synonymous
with
business
practice;
and
income
for
tax
purposes
is
seldom
the
same
as
the
income
shown
on
the
books
of
the
business
for
its
own
purposes.
For
example,
capital
cost
allowance
is
taken
for
tax
purposes
as
the
taxpayer
wishes
(within
the
terms
of
the
Regulations)
while
for
business
purposes
capital
assets
are
likely
to
be
written
off
on
a
straight
line
depreciation
basis.
The
articles
mentioned
above
are
not
authorities
but
they
set
out
what
I
understand
to
be
the
correct
position.
A
distinction
must
be
made
between
a
requirement
that
income
for
tax
purposes
be
accounted
for
generally
in
conformity
with
accounting
principles
and
a
requirement
that
the
taxpayer’s
treatment
of
his
financial
statements
and
his
tax
returns
be
identical.
As
counsel
for
the
taxpayer
contended,
section
9
of
the
Act
is
the
starting
point.
It
provides:
Subject
to
this
Part,
a
taxpayer’s
income
for
a
taxation
year
from
a
business
or
property
is
his
profit
therefrom
for
the
year.
This
has
been
interpreted
as
requiring
a
taxpayer
to
account
for
his
profit
“in
accordance
with
ordinary
commercial
principles’’.
Profit
from
a
business,
subject
to
any
special
directions
in
the
statute,
must
be
determined
in
accordance
with
ordinary
commercial
principles.

of
National
Revenue,
[1962]
SCR
3
[61
DTC

per
Martland,
J
at
page
12.)
The
question
is
ultimately
“one
of
law
for
the
court”.
It
must
be
answered
having
regard
to
the
facts
of
the
particular
case
and
the
weight
which
must
be
given
to
a
particular
circumstance
must
depend
upon
practical
considerations.
As
it
is
a
question
of
law,
the
evidence
of
experts
is
not
conclusive.

Neonex

[1978]
CTC

for
the
rule
that
in
computing
income
for
tax
purposes
generally
accepted
accounting
principles
such
as
the
matching
of
revenues
and
expenses
should
be
adopted
unless
the
Income
Tax
Act
expressly
allows
otherwise.
There
is
no
doubt
that
ordinary
commercial
practices
and
generally
accepted
accounting
principles
would
dictate
that
the
taxpayer
in
this
case
should
have
accounted
for
the
interest
expense
on
the
accrual
basis.
Counsel
for
the
taxpayer,
however,
argues
that
section
20(1)(c)
of
the
Act
specifically
authorizes
a
departure
from
such
principles
and
practices.
This
argument
proceeds
on
two
prongs:
(1)
an
argument
on
the
specific
wording
of
the
statutory
provision
20(1
)(c),
and
(2)
an
argument
by
analogy
to
paragraph
12(1)(c)
of
the
Act
which
deals
with
interest
income.
Paragraph
20(1
)(c)
provides:
.
.
.
in
computing
a
taxpayer’s
income
for
a
taxation
year
from
a
business
or
property,
there
may
be
deducted
..
.
.
an
amount
paid
in
the
year
or
payable
in
respect
of
the
year
(depending
upon
the
method
regularly
followed
by
the
taxpayer
in
computing
his
income),
pursuant
to
a
legal
obligation
to
pay
interest
.
.
.
The
taxpayer’s
argument
is
that
the
words
in
parentheses
in
paragraph
20(1
)(c)
would
be
redundant
and
unnecessary
unless
they
were
intended
to
allow
the
taxpayer
the
option
of
choosing
the
method
by
which
to
account
for
interest
expense
without
constraint
by
ordinary
commercial
practices
or
generally
accepted
accounting
principles.
I
do
not
read
the
words
in
parentheses
this
way.
It
seems
to
me
they
do
no
more
than
instruct
taxpayers
who
use
the
cash
method
of
accounting
to
account
for
interest
expense
using
the
same
method
and
they
instruct
taxpayers
who
use
the
accrual
method
of
accounting
to
account
for
interest
expense
by
that
method.
The
literal
meaning
of
the
words
would
seem
to
require
compliance
with
generally
accepted
accounting
principles
rather
than
authorizing
a
departure
therefrom.
I
note
that
in
the
decision
rendered
in
MNR
v
Mid-West
Abrasive
Company
of
Canada,
[1973]
FC
911
at
920;

CTC

Sweet,
DJ
said
of
these
words:
Wording
to
be
considered
is
“an
amount
paid
in
the
year
or
payable
in
respect
of
the
year’’
in
section
ll(l)(c).
In
my
opinion
the
words
“paid
in
the
year’’
are
applicable
to
theose
taxpayers
who,
in
computing
income,
regularly
follow
the
cash
basis
accounting
method
and
the
words
“payable
in
respect
of
the
year’’
are
applicable
to
those
who,
in
computing
income,
regularly
follow
the
accrual
accounting
method.
With
respect
to
his
second
argument,
counsel
for
the
taxpayer
argues
that
paragraph
12(l)(c)
allows
a
taxpayer
to
choose
the
method
by
which
he
will
account
for
interest
income
without
constraint
of
ordinary
commercial
practices
or
generally
accepted
accounting
principles
because
the
wording
of
paragraph
20(l)(c)
is
essentially
identical
to
that
of
12(l)(c).
He
argues
that
paragraph
12(l)(c)
has
been
interpreted
to
allow
a
hybrid
method
of
accounting
and
therefore
the
same
result
should
follow
for
paragraph
20(1
)(c).
Paragraph
12(l)(c)
provides:
There
shall
be
included
in
computing
the
income
of
a
taxpayer
for
a
taxation
year
any
amount
received
by
the
taxpayer
in
the
year
or
receivable
by
him
in
the
year
(depending
upon
the
method
regularly
followed
by
the
taxpayer
in
computing
his
profit)
as,
on
account
of
in
lieu
of
payment
of,
or
in
satisfaction
of,
interest.
.
.
I
agree
that
there
is
nothing
in
the
statutory
wording
of
the
two
sections
which
would
indicate
that
any
difference
of
treatment
should
exist
between
them.
The
fact
that
paragraph
20(1
)(c)
refers
to
“income”
and
paragraph
12(l)(c)
refers
to
“profits”
does
not
seem
significant.
No
convincing
argument
was
put
to
me
that
there
was
an
intention
to
make
a
distinction
between
the
interpretation
of
the
two
paragraphs
by
the
use
of
these
different
words.
I
think
that
in
the
context
of
the
two
paragraphs
the
words
are
interchangeable.
What
then
does
paragraph
12(1)(c)
allow?
Counsel
for
the
taxpayer
cites
two
sources
for
the
proposition
that
a
taxpayer
is
allowed
under
paragraph
12(l)(c)
to
choose
to
account
for
interest
income
in
a
“non-matching”
fashion:
the
decision
of
this
Court
in
Industrial
Mortgage
and
Trust
Company
v
MNR,
[1958]
CTC
106;
58
DTC
1060
and
the
Department
of
National
Revenue’s
Interpretation
Bulletin
IT-396
dated
October
17,
1977.
It
is
recognized
that
the
interpretation
bulletin
is
not
authority
but
has
some
weight
as
to
interpretation.
See
Nowegijick
v
the
Queen,
[1983]
CTC
20;
83
DTC
5041
at
5044.
The
Industrial
Mortgage
case
involved
a
taxpayer
who
for
most
purposes
used
the
cash
basis
of
accounting.
Eighty-five
per
cent
of
his
income
was
interest
income,
most
of
it
from
mortgages
and
bonds.
The
only
deviation
from
accounting
on
a
cash
basis
was
with
respect
to
the
interest
from
federal
and
provincial
government
bonds,
federal
and
provincial
guaranteed
bonds,
municipal
bonds
and
the
interest
from
some
pre
1-42
mortgages
which
had
never
fallen
into
default.
These
were
accounted
for
on
an
accrual
basis.
Mr
Justice
Thurlow
(as
he
then
was)
at
1061
described
the
reason
for
this
deviation:
There
was
an
explanation
for
this
difference
in
the
appellant’s
accounting
practice
in
respect
to
the
interest
on
these
particular
mortgages.
Prior
to
1931
the
appellant’s
accounts
pertaining
to
interest
on
all
bonds,
mortgages,
agreements
of
sale,
and
collateral
loans
had
been
on
an
accrual
basis,
while
revenues
other
than
interest
on
these
items
were
being
accounted
for
on
a
cash
received
basis.
Between
1931
and
1941,
as
a
result
of
defaults
in
payment
of
mortgage
interest
and
of
the
appellant
having
taken
into
revenue
a
large
amount
of
mortgage
interest
which
it
could
not
collect,
a
number
of
changes
in
the
method
of
taking
interest
into
revenue
were
made,
each
tending
to
some
extent
to
bring
the
method
nearer
to
a
cash
received
basis
on
all
items
except
government
bonds.
By
January
1,
1942,
when
the
last
of
these
changes
was
made,
the
method
of
accounting
for
mortgage
interest
was
that
of
taking
into
revenue
the
interest
on
all
new
loans
on
a
cash
received
basis
while
carrying
on
the
accrual
basis
in
respect
to
the
interest
on
old
loans
on
which
the
interest
had
never
been
in
default.
If
the
interest
on
such
a
loan
subsequently
fell
into
default,
the
accounting
for
interest
on
it
was
immediately
put
on
a
cash
received
basis.
At
page
1064,
Mr
Justice
Thurlow
addressed
the
question
of
the
interpretation
of
paragraph
6(b),
now
paragraph
12(l)(c)
as
follows:
.
.
.
what
is
meant
by
the
word
“method”
in
s
6(b)
and
a
further
question
as
to
whether
or
not
the
appellant
regularly
followed
a
method
of
computing
its
profit.
As
I
interpret
it,
the
word
“method”
is
not
used
in
s
6(b)
in
any
narrow
or
technical
sense
but
simply
means
the
system
or
procedure
which
the
taxpayer
has
regularly
followed
in
computing
his
profit.
The
system
of
procedure,
in
my
opinion,
may
be
made
up
of
a
number
of
practices,
and
I
can
see
no
valid
reason
why,
in
a
diverse
business
such
as
that
of
the
appellant,
such
system
or
procedure
could
not
include
different
practices
for
accounting
for
revenue
from
different
activities
or
sources,
depending
on
the
nature
of
such
activities
or
sources
and
of
the
revenues
therefrom,
and
still
be
regarded
as
a
“method”
within
the
meaning
of
that
word
in
s
6(b).
In
my
opinion,
the
practices
followed
by
the
appellant
did
amount
to
a
“method”
within
the
meaning
of
the
section
and,
as
that
method
had
been
followed
by
the
appellant
without
change
for
the
seven
years
immediately
preceding
1949
and
for
1949
as
well,
I
have
no
hesitation
in
concluding
that
it
was
the
“method”
regularly
followed
by
the
appellant
in
computing
its
profit
within
the
meaning
of
s
6(b).
Bulletin
IT-396
issued
by
the
Department
of
National
Revenue
states
respecting
interest
income:
“Method
Regularly
Followed”
5.
The
words
in
paragraph
12(l)(c)
“depending
upon
the
method
regularly
followed
by
the
taxpayer
in
computing
his
profit”
are
interpreted
to
refer
to
the
taxpayer’s
method
of
accounting
for
net
interest
income
from
a
particular
source
and
not
necessarily,
if
he
is
carrying
on
a
business,
to
his
method
of
accounting
for
profit
from
the
business.
It
is
recognized
that,
for
example,
a
taxpayer
might
choose
the
receivable
basis
of
reporting
interest
on
debts
owing
to
him
that
are
fully
secured
and
the
received
(cash)
basis
for
more
speculative
investments.
Where
such
an
arrangement
was
reasonable
and
was
consistently
followed,
it
would
be
acceptable
as
a
method
of
reporting
interest
income.
While,
as
in
the
above
example,
interest
from
all
sources
need
not
be
reported
on
the
same
basis,
it
is
a
requirement
that
interest
from
the
same
source
must
be
reported
on
the
same
basis.
For
this
purpose,
“interest
from
the
same
source”
refers
to
interest
derived
from
the
same
debtor
on
the
same
type
of
obligation.
For
example,
if
a
taxpayer
owned
bonds
of
two
different
series
issued
by
a
certain
corporation,
interest
from
the
same
source
and
it
would
be
an
unacceptable
method
to
report
interest
from
bonds
of
one
series
on
a
cash
basis
and
interest
on
bonds
of
another
series
on
the
receivable
basis.
The
words
“regularly
followed”
indicate
that
there
will
be
a
consistency
from
year
to
year.
The
Department’s
Interpretation
Bulletin
seems
to
me
no
more
than
a
paraphrase
of
the
Industrial
Mortgage
case.
Counsel
for
the
taxpayer
argues
that
all
a
taxpayer
must
show
to
bring
himself
within
the
hybrid
method
of
accounting
allowed
by
the
Industrial
Mortgage
case
is
an
established
and
consistent
practice
by
the
taxpayer
as
well
as
a
multiplicity
of
lenders.
This
last
requirement
results
from
the
decision
of
Sweet,
DJ
in
MNR
v
MidWest
Abrasive
Company
of
Canada
Ltd,
[1973]
FC
911;
[1973]
CTC
548;
73
DTC
5429,
In
that
case
the
taxpayer
attempted
to
take
into
income,
interest
expense
in
the
year
that
its
parent
company
requested
payment.
Interest
on
the
loans
borrowed
from
the
parent
company
were
stated
to
be
“paid
if
requested
but
not
in
excess
of
6
per
cent”,
The
taxpayer
was
required
by
Sweet,
D
J
to
take
the
interest
expense
into
his
income
on
an
accrual
basis.
The
Industrial
Mortgage
case
was
distinguished
on
the
ground
that
(1)
it
dealt
with
interest
income
and
not
interest
expense;
(2)
there
had
been
an
established
practice
in
that
case
of
many
years
of
reporting
interest
income
on
a
“non-matching”
basis,
and
(3)
there
were
a
multiplicity
of
lenders.
In
the
Mid-West
Abraseve
Company
case,
there
was
only
one
lender,
the
parent
company.
The
decision
proceeds
at
921:
If
the
proper
construction
of
the
section
did
not
confine
the
deduction
which
taxpayers
who
follow
the
accrual
method
(unmodified)
may
take
in
respect
of
interest
to
the
year
in
which
the
borrowed
money
was
used
and
if
the
proper
construction
permitted
it
to
be
deducted
in
some
subsequent
year
(for
whatever
cause)
the
result
would
be
inconsistent
with
the
concept
underlying
the
accrual
method.
In
that
event
one
might
have
“accrual”
in
respect
of
all
matters
except
interest
and
have
a
cash
basis
for
interest.
In
my
opinion
the
wording
of
the
section
does
not
permit
such
a
result
except
in
circumstances
such
as
existed
in
Industrial
Mortgage
and
Trust
Co
v
MNR
(supra)
and
in
my
view
such
circumstances
do
not
exist
in
this
case.
I
do
not
think
it
is
sufficient
on
the
basis
of
the
decisions
in
the
Industrial
Mortgage
and
Mid-West
Abrasive
cases
to
justify
a
hybrid
system
of
accounts
solely
on
the
basis
of
a
consistent
and
established
practice
of
“non-matching”
and
a
multiplicity
of
lenders.
The
principle
I
take
from
those
decisions
is
that
both
paragraphs
20(l)(c)
and
12(l)(c)
require
accounting
in
conformity
with
ordinary
commercial
practices
and/or
generally
accepted
accounting
principles.
The
Industrial
Mortgage
case
is
entirely
consistent
with
this
view.
In
that
case,
it
seems
to
me
the
taxpayer
was
allowed
a
hybrid
system
of
taxation
either
because
(1)
he
was
transferring
from
an
accrual
to
a
cash
basis
of
accounting,
or
(2)
because
the
loans
for
which
he
adopted
the
accrual
method
were
more
secure
than
those
for
which
he
accounted
on
the
cash
basis.
That
is,
even
though
not
expressly
articulated
in
that
case
there
were
valid
reasons
founded
in
ordinary
commercial
practice
and
generally
accepted
accounting
principles
for
allowing
a
hybrid
system
of
accounting.
There
was
no
such
justification
in
the
Mid-West
Abrasive
case
and
no
such
justification
has
been
demonstrated
in
this
case.
Accordingly,
I
would
allow
the
appeal
and
set
aside
the
decision
of
the
Tax
Review
Board.
