Mahoney,
J:—At
the
opening
of
the
trial,
the
parties
filed
minutes
of
settlement
which
disposed
of
all
but
one
of
the
issues
raised
in
the
pleadings.
The
defendant
is,
inter
alia,
a
building
contractor.
It
seeks
to
exclude
from
its
taxable
income
for
the
year
ended
July
31,
1968,
an
amount
of
$227,171.
That
is
the
amount
referred
to
in
paragraph
3
of
the
statement
of
agreed
facts.
The
full
text
of
the
statement
of
agreed
facts
follows:
1.
The
parties
agree
that
as
of
July
31,
1968,
there
was
a
total
of
$452,123
of
accounts
receivable
of
the
appellant
for
which
architect’s
certificates
had
to
be
issued
before
the
Company
was
entitled
to
receive
payment
and
for
which
such
certificates
had
not
been
issued
on
or
before
July
31,
1968.
2.
The
parties
further
agree
that
the
appellant
overstated
certain
accounts
payable
as
of
July
31,
1968
in
a
total
amount
of
$57,426.
In
addition,
the
appellant
incorrectly
treated
as
part
of
its
costs
incurred
in
1968
a
total
of
$167,526
in
respect
of
work
done
for
it
by
subcontractors
for
which
architect’s
certificates
had
to
be
issued
before
the
appellant
was
liable
to
make
payment
and
for
which
such
certificates
had
not
been
issued
on
or
before
July
31,
1968.
3.
The
net
effect
of
these
adjustments,
if
allowed,
is
to
reduce
the
appellant’s
1968
income
by
$227,171,
which
totally
eliminates
its
taxable
income
for
1968
and
results
in
a
loss
which
is
deductible
in
computing
its
taxable
income
for
1967.
The
defendant
rested
its
case
in
chief
on
the
agreed
facts
relying
on
MNR
v
John
Colford
Contracting
Co
Ltd,
[1960]
Ex
CR
433;
[1962]
SCR
viii;
[1960]
CTC
178;
60
DTC

[1962]
CTC

and
the
corollary
decision
in
J
P
Guay
Ltée
v
MNR,
[1971]
FC
237;
[1971]
CTC
686;
71
DTC
5423,
as
authority
for
the
proposition
that
neither
the
$452,123
accounts
receivable
nor
the
$224,952
accounts
payable
ought
to
be
taken
into
account
in
calculating
the
defendant’s
income
for
its
1968
taxation
year.
In
addition
to
the
agreed
facts,
I
have
the
uncontradicted
evidence
of
Robert
Arthur
Weavers,
an
official
of
the
Department
of
National
Revenue,
who
conducted
the
investigations
that
led
to
the
assessment
in
issue.
In
filing
its
returns
for
its
taxation
years
1962
through
1969,
inclusive,
the
defendant
consistently
reported
its
income
including
holdbacks
and
uncertified
progress
claims
outstanding
as
at
year
end
in
the
calculation
of
its
income.
For
its
1970
and
1971
taxation
years,
the
defendant
excluded
holdbacks
from
the
calculation
but
continued
to
include
uncertified
progress
Claims.
On
December
29,
1971,
notices
of
re-assessment
of
the
defendant’s
1967
and
1968
returns
were
issued.
They
dealt
with
a
multitude
of
items
no
longer
disputed
by
the
parties
but
not,
of
course,
with
the
matter
remaining
in
issue.
The
Minister
did
not
object
to
the
defendant’s
reporting
of
its
holdbacks
and
uncertified
progress
claims
as
receivable
and
payable
since,
in
the
ordinary
course
of
events
over
a
period
of
years,
that
practice
had
the
effect
of
anticipating,
rather
than
deferring,
tax
liability.
The
issue
was
first
raised
by
the
defendant
itself
in
notices
of
objection
dated
March
15,
1972.
The
defendant
claimed
the
right,
in
the
notices
of
objection,
to
deduct
“holdbacks
contingently
receivable”
in
the
sums
of
$117,552
as
to
1967
and
$90,013
as
to
1968.
The
Minister
took
no
action
on
the
notices
of
objection
and,
on
March
14,
1974,
in
a
notice
of
appeal
to
the
Tax
Review
Board,
the
defendant
asserted
that
right
in
the
following
terms:
3.
In
computing
its
income
for
the
1967
taxation
year,
the
appellant
deducted
holdbacks
totalling
$117,552.
4.
In
computing
its
income
for
the
1968
taxation
year,
the
appellant
deducted
holdbacks
in
the
sum
of
$90,013.
5.
By
notices
of
reassessment
dated
December
29,
1971,
in
respect
of
the
1967
and
1968
taxation
years,
the
Respondent
reassessed
the
appellant
and
increased
its
declared
income
by
including
the
sums
of
$117,552
and
$90,013
which
had
previously
been
deducted
as
holdbacks.
The
process
by
which
the
claimed
deduction
of
$117,552
for
1967
and
$90,013
for
1968
became
the
net
claim
of
$227,171
for
1968
alone
that
was
ultimately
in
issue
before
the
Tax
Review
Board,
and
remains
in
issue
here,
is
not
in
evidence.
What
the
defendant,
in
fact,
did
was
set
up
two
reserves
out
of
income:
one
for
holdbacks
contingently
receivable
and
the
other
for
contingent
maintenance
and
overbilling.
In
his
reply
to
the
notice
of
assessment,
filed
September
20,
1974,
the
Minister
denied
the
allegations
contained
in
paragraphs
3,
4
and
5
of
the
notice
of
appeal
and
disputed
the
propriety
of
the
reserves.
At
that
point
in
time,
the
reserves,
for
the
1968
taxation
year
only,
mentioned
in
the
reply
amounted
to
$57,428.29
for
holdbacks
and
$50,985
for
the
maintenance
and
overbilling
contingencies.
Weavers
had
understood
from
the
defendant
that
it
wanted
to
alter
its
method
of
reporting
holdbacks
receivable
and
payable.
The
method
he
understood
is
that
in
fact
adopted
by
the
defendant
for
1970
and
1971.
He
saw
no
particular
problem
with
effecting
that
change
for
the
1968
taxation
years
since
the
total
holdbacks
reported
as
receivable
and
payable
as
at
July
31,
1968,
were
practically
identical
amounts:
$57,428.39
receivable,
$57,425.82
payable.
In
the
reply,
the
disallowance
of
the
holdback
contingency
reserve
was
dealt
with
in
the
following
terms:
12.
The
respondent
submits
that
in
computing
the
appellant’s
income
for
the
1968
taxation
year
he
properly
disallowed
as
a
deduction
the
sum
of
$57,428.39
since
the
appellant
overstated
its
expenses
by
that
amount
and
as
such
was
prohibited
from
deduction
by
virtue
of
sections
3,
4
and
paragraph
12(1)(a)
of
the
Income
Tax
Act.
The
maintenance
and
overbilling
contingency
reserve
was,
however,
simply
dealt
with
on
the
basis
of
its
not
being
permitted
by
the
Act.
The
parties’
representatives
met
November
4,
1974.
Weavers
was
present.
The
statement
of
agreed
facts
was
completed
for
the
Tax
Review
Board
hearing
which
began
November
7.
It
was
at
that
meeting
that
Weavers
first
learned
of
the
defendant’s
intention
to
seek
to
deduct
the
uncertified
progress
claims
as
at
the
end
of
its
1968
tax
year
as
distinct
from
seeking
to
set
up
and
deduct
the
maintenance
and
overbilling
contingency
reserve.
By
then,
re-assessment
of
the
defendant’s
1969
return
was
statute
barred.
That
assessment
is
not
before
me
and
I
upheld
the
defendant’s
objection
to
the
admissibility
of
evidence
on
the
hypothetical
issue
of
the
re-assessment
that
would
ordinarily
have
resulted
from
the
changes
the
defendant
seeks,
by
this
action,
to
make
in
its
1968
income.
The
learned
member
of
the
Tax
Review
Board
accepted
the
argument
which
the
defendant
urges
me
to
accept,
namely:
that
the
amounts
in
issue
and
their
nature
are
clearly
established
by
the
statement
of
agreed
facts
and
their
inclusion
in
the
calculation
of
the
defendant’s
taxable
income
is
clearly
contrary
to
the
jurisprudence.
The
issue
is
not,
in
my
view,
that
simple.
While
the
Co/ford
and
Guay
cases,
to
the
extent
they
are
germane
to
the
issue
here,
dealt
only
with
holdbacks
as
distinct
from
uncertified
progress
claims,
I
accept
that
they
apply
equally
to
the
latter
type
of
accounts
receivable
and
payable
in
this
case.
In
my
view
they
are
authority
for
the
proposition
that
a
taxpayer
may
exclude
such
amounts
in
the
calculation
of
his
income
under
the
Income
Tax
Act.
They
are
not
authority
for
the
proposition
that
he
must
exclude
them
or,
to
put
in
another
way,
that
if
the
taxpayer
does
not
exclude
them,
the
Minister
is
obliged
to
re-assess
to
exclude
them.
It
is
trite
to
say
that
the
Income
Tax
Act
creates
a
self-assessing
income
tax
system.
A
person
liable
to
tax
is
required
to
prepare
and
file
a
tax
return
in
which
he
calculates
his
income
and
the
tax
payable
in
respect
of
it.
He
is
obliged
to
make
those
calculations
in
accordance
with
the
requirements
of
the
Act
and,
by
the
assessment
process,
the
Minister
is
supposed
to
ensure
that
he
does.
The
Act,
as
it
stood
during
the
period
in
issue,
provided
that
a
taxpayer’s
income
for
a
taxation
year
included
his
income
for
the
year
from
all
businesses
and
that
4.
Subject
to
the
other
provisions
of
this
Part,
income
for
a
taxation
year
from
a
business
.
.
.
is
the
profit
therefrom
for
the
year.
There
are
no
“other
provisions”
that
would
have
prohibited
the
defendant
from
including
the
holdbacks
and
uncertified
progress
claims,
outstanding
at
year
end,
in
the
calculation
of
its
profit
for
the
year.
In
the
absence
of
such
“other
provisions”,
the
profit
must
be
computed
in
accordance
with
generally
accepted
accounting
principals.
I
have
no
evidence
as
to
what
those
principals
are
and
probably
ought
not
take
judicial
notice
of
what
I
deem
them
to
be.
Suffice
it
to
say,
while
I
lean
to
the
conclusion,
on
the
evidence,
that
there
are
probably
at
least
two
acceptable
methods
of
accounting
for
the
amounts
in
issue,
the
defendant
has
not
discharged
the
onus
on
it
of
proving
that
the
application
of
different
acceptable
methods
to
successive
fiscal
periods
accords
with
generally
accepted
accounting
principles.
The
plaintiff
also
pleads
that
the
defendant
is,
in
any
event,
now
estopped
from
changing
the
basis
upon
which
the
uncertified
progress
claims
are
to
be
treated
in
the
calculation
of
its
profit
for
its
1968
taxation
year.
I
agree.
The
defendant
reported,
in
its
1968
tax
return,
income
based
on
a
profit
calculation
that
included
the
uncertified
progress
claims
made
by
and
upon
it.
That
was
consistent
with
the
way
it
had
calculated
its
profit
since
1962
and
would
continue
to
report
it
through
1971.
In
both
its
notices
of
objection
and
notice
of
appeal
to
the
Tax
Review
Board,
it
referred
to
holdbacks
“contingently
receivable”
and
“not
legally
receivable”
in
its
1967
and
1968
taxation
years.
It
did
not
refer
to
the
uncertified
progress
claims.
The
allegations
of
fact
in
paragraphs
3,
4
and
5
of
the
notice
of
appeal
are
not
true.
The
defendant
had
not
deducted
holdbacks
totalling
$117,552
and
$90,013
respectively
in
computing
its
1967
and
1968
income
nor,
by
the
notices
of
re-assessment,
had
the
Minister
increased
the
defendant’s
income
by
those
amounts.
I
considered
it
necessary
to
make
those
findings
and
recited
those
paragraphs
because,
in
these
procedings,
the
defendant
did
not
find
it
necessary
to
repeat
them,
being
content
to
take
as
its
points
of
departure
the
statement
of
agreed
facts
and
the
decision
of
the
Tax
Review
Board.
The
defendant
did
indicate
a
desire
to
change
its
method
of
accounting
insofar
as
holdbacks
were
concerned
when
such
a
change
could
have
been
effected
for
1968
at
a
time
when
any
consequental
adjustments
of
its
1969
income
could
have
been
effected
by
re-assessment.
It
indicated
its
desire
to
change
its
method
of
accounting
for
uncertified
progress
claims
for
1968
too
late
to
permit
re-assessment
of
its
1969
return.
While
evidence
as
to
magnitude
of
the
disadvantage
in
dollars
and
cents
was
not
admitted,
Weavers’
evidence
is
that
should
such
a
change
for
1968
be
permitted
without
a
complementary
reassessment
for
1969
there
would
be
a
loss
of
tax
revenue.
The
defendant
made
representations
as
to
its
1968
and
1969
profits
by
the
consistent
way
it
calculated
them.
The
plaintiff
acted
on
those
representations
in
the
assessment
of
the
returns
for
both
years.
If
the
defendant
is
permitted
to
change
its
method
of
calculating
its
1968
profit,
thereby
denying
the
representations
upon
which
the
plaintiff
acted,
the
plaintiff
will
be
in
the
position
of
having
acted
to
her
detriment.
In
essence,
what
the
defendant
seeks
is
to
change
its
method
of
accounting
for
its
profit
to
be
effective
for
its
1968
taxation
year
without
applying
the
same
method
to
1969.
That
is
contrary
to
reason
and,
in
my
view,
also
contrary
to
law.
The
defendant’s
1967
and
1968
returns
will
be
referred
back
to
the
Minister
of
National
Revenue
for
reassessment
in
accordance
with
these
reasons
and
with
the
minutes
of
settlement
filed
herein.
The
plaintiff
is
entitled
to
costs.
