Lamarre
Proulx,
T.C.J.:
—The
appellant
appeals
from
a
reassessment
of
tax
in
respect
of
the
1985
taxation
year.
The
appeal
concerns
the
requirements
of
subsection
56.1(3)
of
the
Income
Tax
Act
(the
Act)
for
its
application
and
the
validity
of
a
clause
in
a
separation
agreement.
Mr.
Ron
Dilabio,
the
appellant’s
former
spouse,
was
joined
as
a
party
to
the
appeal
of
the
appellant
by
an
order
of
this
Court
issued
on
April
6,
1989
by
virtue
of
paragraph
174(3)(b)
of
the
Act.
That
order
was
issued
on
the
basis
that
it
appeared
that
a
determination
of
the
question
set
forth
in
an
application
made
by
the
respondent
pursuant
to
section
174
of
the
Act
and
dated
February
2,
1989
will
affect
the
assessments
in
respect
of
the
appellant
and
the
party
joined.
The
determination
of
the
question
follows
the
reasons
for
judgment.
Sharon
Stewart
and
Ron
Dilabio
were
married
on
October
12,
1968.
They
have
two
children,
one
born
in
1972
and
the
other
in
1975.
Irreconcilable
differences
arose
between
the
spouses
and
in
August
1986
a
first
draft
of
a
separation
agreement
was
produced
to
the
appellant.
It
contained
the
following
clause:
6(b)
(1)
The
husband
shall
pay
the
sum
of
$300.00
for
each
child
for
maintenance
of
that
child
(making
a
total
of
$600.00
for
two
children)
payable
on
the
1st
day
of
September
1986,
until
one
of
the
following
occurs:
The
appellant
reviewed
the
draft
agreement
that
had
been
sent
to
her
by
her
lawyer.
She
was
pleased
with
the
text,
except
that
she
wanted
$400
per
child
per
month
and
a
few
other
minor
changes.
In
her
lawyer's
presence,
she
initialled
the
changes
requested
and
signed
a
copy
of
the
agreement.
That
was
done
on
September
15,
1986.
The
signing
in
advance
was
made
at
her
lawyer's
request
purportedly
to
facilitate
the
lawyer's
task
in
obtaining
an
executed
copy.
The
executed
copy
is
dated
December
15,
1986
and
it
contains
the
following
clauses:
6(b)
(I)
The
wife
acknowledges
receipt
of
support
payments
in
the
amount
of
$1,035.00
for
1985
up
to
and
including
the
month
of
June,
1986
and
thereafter
the
sum
of
$600.00
per
month
until
December,
1986.
(II)
The
husband
shall
pay
the
sum
of
$350.00
for
each
child
for
the
maintenance
of
that
child
(making
a
total
of
$700.00
for
two
children)
payable
on
the
1st
day
of
January,
1987
until
one
of
the
following
occurs:
Clause
6(b)(1)
is
the
contentious
clause.
As
previously
mentioned,
the
changes
on
the
August
1986
draft
had
been
initialled
by
Ms.
Stewart,
so
that
ultimately
on
the
December
copy
all
the
changes
were
properly
initialled
by
the
appellant,
except
that
clause.
The
lawyer
of
the
appellant
at
the
time
of
the
separation
testified
to
the
effect
that
she
never
consented
to
this
inclusion
and
the
evidence
showed
that
Ms.
Stewart
who
knew
the
tax
consequences
of
such
an
admission,
never
consented
to
it
and
had
repeatedly
not
consented
to
it.
Here
are
some
excerpts
of
the
lawyer's
testimony:
Q.
Specifically
to
clarify,
did
Sharon
Dilabio
ever
agree
to
the
acknowledgment
clause?
A.
No,
because
we
had
discussed
several
drafts
where
it
had
been,
and
she'd
always
said,
No,
that's
not
correct
because
I
didn't
get
that
money."
Q.
Did
you
ever
agree
to
the
acknowledgment
clause
on
her
behalf?
A.
No.
Q.
Would
you
have
gotten
her
approval
if
you
had
had
discussions
and
made
a
tentative
agreement,
would
you
have
gotten
her
approval?
A.
Yes,
if
I'd
realized
that
that
clause
had
been
added,
I
would
have
phoned
her
immediately
before
doing
anything,
and
I'd
have
said,
"Look,
they've
got
this
clause
on
the
new
page;
what
about
it?
Q.
Would
you
have
advised
your
client
for
or
against
incorporating
an
acknowledgment
clause
in
the
separation
agreement,
and
why?
A.
Well
if
she
had
received
the
money,
it
would
have
been
fine.
But
she
informed
me
she
never
received
the
money;
it
had
been
paid
to
some
third
party,
some
of
it.
A.
He
told
me
he
was
going
to
have
the
page
re-typed.
I
don't
recall
that
he
ever
said
he
was
going
to
add
the
acknowledgment
clause.
When
the
appellant
received
the
December
copy,
she
did
not
review
it
as
she
had
done
for
the
August
copy.
She
had
been
informed
by
her
lawyer
that
only
the
changes
that
she
had
consented
to
had
been
included.
As
an
indication
that
the
appellant
never
wanted
to
make
the
contentious
admission
is
that
she
insisted
on
updating
the
starting
date
of
the
maintenance
payments.
The
lawyer
for
the
husband
in
the
preparation
of
the
agreement,
also
testified.
He
said
that
he
recalled
having
mentioned
to
the
appellant's
lawyer
that
his
client
wanted
this
acknowledgment
clause
to
be
inserted
in
and
that
she
had
agreed
to
it.
This
was
done
over
the
phone.
Nothing
else
about
that
acknowledgement
clause
has
ever
been
mentioned
in
the
husband's
lawyer's
memoranda
to
the
appellant's
lawyer.
A
letter
from
the
appellant's
lawyer
to
the
appellant
dated
January
17,
1987
and
filed
into
Court
as
Exhibit
A-5
mentions
the
impugned
clause
though
it
is
not
clear
whether
this
had
been
discussed
over
the
phone
and
had
been
agreed
to
by
the
appellant's
lawyer.
At
your
request
I
am
enclosing
a
copy
of
the
Separation
Agreement
which
you
signed
on
12th
September,
1986,
but
which
was
not
signed
in
that
form
by
Mr.
Dilabio.
As
you
know,
it
shows
the
sum
of
$350.00
to
be
paid
by
your
husband
in
monthly
support
for
each
of
the
two
children,
as
inserted
and
initialled
by
you.
I
also
enclose
copies
of
the
two
pages
prepared
by
your
husband's
lawyer
and
included
in
the
Agreement
at
his
insistence
before
he
signed
it
on
15th
December,
1986.
They
show
that
you
acknowledge
the
sum
of
$1,035.00
paid
to
you
in
monthly
support
in
1985
and
until
June,
1986.
Neither
your
husband
nor
his
lawyer
ever
discussed
this
paragraph
with
you
or
me,
and
it
seems
possible
that
it
may
invalidate
the
whole
agreement,
since
you
did
not
assent
to
it
when
you
signed.
In
her
testimony,
the
appellant's
lawyer
had
said
repeatedly
that
she
does
not
recall
the
husband's
lawyer
ever
discussing
this
insertion
of
the
acknowledgment
clause
in
the
agreement.
However,
because
of
the
fact
that
she
did
not
react
in
an
outraged
manner
to
what
would
be
an
outrageous
act
(she
tried
to
negotiate
a
settlement
with
the
husband's
lawyer,
she
did
not
advise
her
client
to
immediately
repudiate
the
agreement),
I
am
not
convinced
that
the
husband's
lawyer
had
not
mentioned
the
insertion
to
the
appellant's
lawyer.
I
find
this
confusing
and
I
believe
that
I
should
disregard
the
appellant's
lawyer's
testimony
on
that
aspect.
At
the
outset
of
the
hearing,
counsel
for
the
joined
party
stated
that
I
did
not
have
jurisdiction
to
declare
upon
the
validity
of
a
clause
in
a
separation
agreement.
That
was
one
part
of
his
statement.
The
other
part
was
that
the
burden
of
proof
was
on
the
appellant
and
that
his
client
was
in
the
position
of
a
defendant
and
that
he
did
not
intend
to
adduce
any
evidence.
I
informed
him
of
my
view
that
the
joined
party
was
not
in
the
same
position
as
a
defendant
but
rather
in
the
position
of
a
quasi
appellant
and
that
he
had
to
make
his
case.
With
respect
to
the
jurisdiction
of
this
Court,
he
argued
that
this
Court
had
jurisdiction
to
interpret
an
agreement
but
no
jurisdiction
to
invalidate
a
clause
in
an
agreement.
Counsel
for
the
respondent
stated
forcefully
that
this
Court
had
jurisdiction
to
determine
the
validity
of
the
contentious
clause
as
it
was
pursuant
to
that
clause
that
the
appellant
had
been
assessed:
the
appellant
is
appealing
her
assessment
on
the
ground
that
this
clause
is
not
valid
and
therefore
I
have
jurisdiction
to
determine
whether
or
not
this
clause
is
valid.
He
referred
me
to
sections
169
and
171
of
the
Act
and
to
sections
12
and
13
of
the
Tax
Court
Act
and
to
the
following
cases:
McMillen
Holdings
Ltd.
v.

(B.C.C.A.).
Counsel
for
the
respondent
submitted
that
in
dealing
with
an
appeal
which
flows
directly
from
an
assessment,
the
doctrine
of
collateral
attack
would
hold
that
the
Tax
Court
of
Canada
has
the
jurisdiction
to
decide
all
issues
which
are
necessary
and
ancillary
for
reaching
its
decisions.
He
stated
also
that
for
example,
the
Tax
Court
of
Canada
deals
in
issues
on
a
daily
basis
which
touch
on
matters
which
are
of
provincial
jurisdiction.
This
is
seen
through
cases
such
as,
for
instance,
those
dealing
with
partnerships,
commercial
transactions,
sales,
leasehold
interest
and
other
transactions
of
the
like.
The
Court
has
on
numerous
occasions
decided
whether
there
are
partnerships
which
exist,
whether
a
building
was
sold
at
fair
market
value,
whether
there
exists
a
valid
contract
of
sale
and
whether
there
exists
a
contract
of
employment.
These
are
all
collateral
issues
which
arise
out
of
its
jurisdiction
to
dismiss
or
allow
an
appeal,
or
vacate
or
vary
an
assessment.
I
agree
with
these
statements.
The
appeal
cannot
be
kept
in
abeyance
until
the
matter
of
the
validity
of
the
clause
is
resolved
by
the
relevant
Provincial
Court.
I
have
to
determine
whether
the
contentious
clause
is
valid
or
not
because
it
is
a
ground
of
appeal
of
the
appellant.
I
say
a
ground
of
appeal
because
counsel
for
the
appellant
submitted
in
her
argument
as
a
first
ground
of
appeal
that
the
clause
in
question
as
drafted
did
not
meet
the
requirements
of
subsection
56.1(3)
and
it
is
as
a
supplementary
argument
that
she
submitted
the
argument
on
the
validity
of
the
clause.
That
latter
ground
was
the
only
ground
that
had
been
raised
by
the
appellant
in
her
notice
of
appeal.
She
was
not
then
represented
by
a
lawyer.
Subsection
56.1(3)
of
the
Act
reads
as
follows:
For
the
purposes
of
this
section
and
section
56,
where
a
decree,
order
or
judgment
of
a
competent
tribunal
or
a
written
agreement
made
at
any
time
in
a
taxation
year
provides
that
an
amount
received
before
that
time
and
in
the
year
or
the
immediately
preceding
taxation
year
is
to
be
considered
as
having
been
paid
and
received
pursuant
thereto,
the
following
rules
apply:
(a)
the
amount
shall
be
deemed
to
have
been
received
pursuant
thereto;
and
(b)
the
person
who
made
the
payment
shall
be
deemed
to
have
been
separated
pursuant
to
a
divorce,
judicial
separation
or
written
separation
agreement
from
his
spouse
or
former
spouse
at
the
time
the
payment
was
made
and
throughout
the
remainder
of
the
year.
When
I
read
clause
6(b)(1)
of
the
agreement
in
relation
to
the
requirements
of
subsection
56.1(3)
of
the
Act,
I
find
that
counsel's
point
is
well
taken.
The
provision
says
clearly
that
it
is
when
a
written
agreement
provides
that
an
amount,
received
before
the
agreement
was
made,
is
to
be
considered
as
having
been
paid
and
received
pursuant
to
that
agreement,
that
the
rules
described
in
that
section
will
apply.
There
are,
in
my
view,
two
essential
elements
required
by
subsection
56.1(3)
in
drafting
a
clause:
there
should
be
mutual
agreement
as
to
the
amounts
received,
and
that
these
amounts
should
be
considered
as
having
been
paid
pursuant
to
the
agreement.
I
find
that
the
clause
under
study
lacks
the
second
essential
element:
mutual
agreement
that
the
amounts
received
(in
the
year
or
the
immediately
preceding
year)
are
to
be
considered
as
having
been
paid
and
received
pursuant
to
the
agreement.
This
argument
on
the
formal
requirements
of
subsection
56.1(3)
appears
to
me
to
be
reinforced
by
the
wording
of
the
last
lines
of
subsection
56.1(2)
which
says
the
following:
.
.
.
shall,
where
the
decree,
order,
judgment
or
written
agreement,
as
the
case
may
be
provides
that
this
subsection
and
subsection
60.1(2)
shall
apply
to
any
payment
made
pursuant
thereto,
be
deemed
to
be
an
amount
paid
by
that
person
and
received
by
the
taxpayer
as
an
allowance
payable
on
a
periodic
basis.
I
agree
with
the
argument
of
the
appellant's
lawyer.
Not
only
shall
the
clause
stipulate
that
amounts
have
been
received
in
the
year
or
the
previous
year
but
it
should
also
be
clear
that
the
parties
want
these
amounts
to
be
considered
as
having
been
paid
and
received
pursuant
to
the
agreement.
On
this
ground,
the
appeal
shall
succeed.
Could
it
have
succeeded
on
the
ground
of
the
validity
of
the
clause?
I
have
come
to
the
conclusion
that
it
could
not
have
succeeded
on
that
ground
and
hereafter
are
my
views
of
the
matter.
I
am
of
the
opinion
that
there
are
two
legal
questions
to
be
considered
in
order
to
resolve
the
matter
of
the
validity
of
the
clause.
One
is
the
mandate
given
to
a
lawyer
and
the
other
is
the
unilateral
mistake.
In
Bowstead
on
Agency,
15th
ed.
Sweet
&
Maxwell,
1985,
we
read
at
page
95:
The
extent
of
the
implied
authority
of
a
solicitor
to
compromise
is
however
not
clear.
It
would
seem
that
the
apparent
authority
of
a
solicitor
in
this
respect
can
only
be
supported
if
there
is
in
general
implied
authority
to
compromise
in
a
fair
and
reasonable
manner:
only
this
could
support
general
apparent
authority
to
the
outside
world.

(Sask.
Q.B.)
where
the
defendants
were
to
be
held
bound
by
the
agreement
even
though
the
terms
of
the
agreement
were
not
their
understanding
of
the
terms.
The
Court
found
that
there
had
been
no
suggestion
that
the
defendant's
lawyer
had
limited
authority
and
that
no
such
limitation
had
been
communicated
to
the
other
party
prior
to
the
signing
of
the
agreement.
There
is
also
the
matter
of
the
unilateral
mistake.

Stepps
Investments
Ltd.
et
al.
v.
Security
Capital
Corporation
Ltd.
(1976),
14
O.R.
(2d)
259,
Mr.
Justice
Grange
states
the
following
at
pages
272-73:
it
is
not
unreasonable,
in
my
view,
in
modern
commercial
relations,
to
require
the
parties,
where
an
important
amendment
is
being
made,
to
ensure
that
knowledge
of
such
amendment
comes
to
the
other
side.
I
do
not
mean
that
a
party
must
overcome
obtuseness
in
his
opposite
number
but
he
must
at
least
give
him
a
real
opportunity
to
appreciate
the
change.
And
if
the
circumstances
are
such
that
the
amendment
might
readily
be
missed
he
should
be
particularly
reluctant
to
assume
such
knowledge.
Here
the
plaintiffs
cc
'lld
have
resolved
the
whole
problem
by
a
clear
reference
to
the
amendment
in
the
correspondence
or
in
the
recitals
or
the
operative
parts
of
the
agreement
itself.
It
could
even
have
been
resolved
in
a
clear,
unambiguous,
oral
conversation
with
the
defendant's
solicitors
and
I
cannot
find
that
such
a
clear
and
unambiguous
conversation
ever
took
place.
The
headnote
explaining
that
case
says
"the
significance
of
this
alteration
was
not
brought
to
the
attention
of
the
defendant
or
his
solicitor."
And
in
The
Law
of
Contract,
2nd
ed.,
Carswell,
1986,
G.H.L.
Fridman,
Q.C.,
the
learned
author
notes
at
242-43:
It
is
not
necessary
for
the
party
seeking
to
avoid
the
contract
on
the
ground
of
mistake
to
prove
that
the
other
party
caused
or
induced
the
mistake
(although
if
such
causation
is
established
it
might
lead
to
rescission
for
fraud,
or
for
innocent
misrepresentation).
As
long
as
the
unmistaken
party
knows
of
the
mistake,
without
having
caused
it,
that
party
cannot
resist
a
suit
for
rectification
on
the
grounds
of
mistake.
The
converse
of
the
proposition
as
to
knowledge
of
the
other
party's
mistake
is
that
if
the
unmistaken
party
is
ignorant
of
the
other's
mistake
the
contract
will
be
valid
and
neither
rescission
nor
rectification
will
be
possible.
In
the
present
case,
I
would
have
been
inclined
to
find
under
both
arguments:
the
limited
lawyer's
mandate
and
the
unilateral
mistake,
that
the
contentious
clause
was
not
valid
and
even
more
so
because
the
joined
party
did
not
testify.
I
could
have
drawn
a
negative
inference
that
he
knew
of
the
lawyer's
limited
mandate
and
of
the
appellant's
unilateral
mistake.
However,
in
both
of
the
above
described
situations,
if
the
party,
who
wishes
to
raise
as
grounds
of
rescission
of
the
contract,
the
knowledge
of
the
limitation
of
the
agent's
authority
or
the
unilateral
mistake,
has
otherwise
ratified
the
agreement
after
the
discovery
of
the
unauthorized
part
of
the
agreement
or
affirmed
the
agreement
by
not
repudiating
or
denouncing
it,
or
by
adopting
other
parts
of
the
agreement,
that
party
is
bound
by
his
ratification
or
by
his
affirmation.
See
Chitty
on
Contracts,
General
Principles,
25th
ed.
paragraph
453
at
page
252.
If
the
appellant
had
repudiated
the
agreement
outright
when
she
discovered
the
mistake
or
the
inclusion
of
the
contentious
clause,
it
would
have
put
me
in
a
position
where
I
could
have
decided
upon
the
validity
of
the
contentious
clause,
but
by
not
having
done
so,
I
am
of
the
view
that
in
the
circumstances
the
appellant
is
to
be
considered
as
having
agreed
to
the
clause
in
question.
The
appellant's
lawyer
raised
also
an
argument
respecting
the
wording
of
the
contentious
clause
and
submitted
that
the
only
amount
acknowledged
is
an
amount
of
$1,035
up
to
June
1986
and
that
the
words
per
month
should
not
be
implicitly
added
after
the
figure
of
$1,035
in
clause
6(b)(1)
of
the
agreement.
She
submits
that
a
clause
of
an
agreement
when
ambiguous
should
be
interpreted
contra
proferentem.
This
may
be
so
when
the
evidence
does
not
bring
certainty
to
the
Court
as
to
the
exact
meaning
of
the
words.
In
the
present
case
the
evidence
showed
that
the
appellant
received
$300
per
month
and
that
the
husband
was
paying
the
property
charges
in
a
monthly
sum
of
$735
until
the
house
was
sold
in
June
1986
and
that
after
that
he
paid
the
sums
of
$600
per
month.
I
find
that
the
only
sense
that
can
be
made
out
of
clause
6(b)(1)
is
to
determine
that
the
words
"per
month"
are
implied.
(On
this
matter,
see
McClelland
&
Stewart
Ltd.
v.
Mutual
Life,
[1981]

S.C.R.

However,
on
the
basis
of
the
drafting
requirements
of
subsection
56.1(3)
of
the
Act,
the
appeal
is
allowed
with
costs
and
the
matter
referred
back
to
the
respondent
for
reconsideration
and
reassessment.
Determination
The
question
set
forth
in
the
respondent's
application
pursuant
to
section
174
of
the
Act
and
dated
February
2,
1989
is
the
following:
The
question
in
respect
of
which
the
Minister
of
National
Revenue
requests
a
determination
is
whether
the
whole
or
any
part
of
said
payments
were
made
by
Ron
Dilabio
and
received
by
Sharon
Stewart
and,
if
so,
whether
they
were
amounts
paid
by
him
pursuant
to
a
written
agreement
as
alimony
or
other
allowance
payable
on
a
periodic
basis
for
her
benefit
and
maintenance
and
that
of
the
children
of
the
marriage
and
whether
Ron
Dilabio
was
living
apart
and
separated
from
Sharon
Stewart,
to
whom
he
was
required
to
make
the
payments,
pursuant
to
a
written
separation
agreement
at
the
time
the
payments
were
made
and
throughout
the
remainder
of
they
year,
such
that
they
are
deductible
by
Ron
Dilabio
in
the
computation
of
his
income
for
the
1985
taxation
year
pursuant
to
paragraph
60(b)
and
subsections
60.1(1)
and
60.1(3)
of
the
Income
Tax
Act,
R.S.C.
1952,
c.
148,
as
amended
for
the
1985
taxation
year,
and
are
to
be
included
in
the
computation
of
Sharon
Stewart's
income
for
1985
pursuant
to
paragraph
56(1)(b)
and
subsections
56.1(1)
and
56.1(3)
of
the
Income
Tax
Act,
R.S.C.
1952,
c.
148,
as
amended
for
the
1985
taxation
year.
On
the
basis
of
my
findings
in
the
above
reasons
for
judgment,
I
determine
the
question
as
follows:
the
said
payments
were
made
by
Mr.
Dilabio
to
Mrs.
Stewart
but
they
were
not
made
pursuant
to
a
written
agreement:
the
written
agreement
did
not
provide
that
the
said
amounts
were
to
be
considered
as
having
been
paid
and
received
pursuant
thereto
and
therefore
they
are
not
deductible
by
Mr.
Dilabio
in
the
computation
of
his
income
for
the
1985
taxation
year.
Appeal
allowed.
