Taylor,
T.C.J.:—This
is
an
appeal
against
an
income
tax
assessment,
for
the
year
1984,
heard
in
London,
Ontario,
on
March
2,
1987,
in
which
the
Minister
of
National
Revenue
disallowed
the
“personal
exemption”
claimed
by
the
taxpayer.
The
Minister's
reply
to
notice
of
appeal
read
in
part:
Statement
of
Facts
—
the
appellant
was
a
non-resident
of
Canada
who
worked
in
Canada
and
the
United
States.
—
the
Appellant’s
net
income
from
Canadian
sources
was
$25,400
and
income
from
United
States
sources
was
16,741.63
(Cdn.);
—
all
or
substantially
all
of
the
Appellant’s
income
for
the
1984
year
was
not
included
in
computing
his
taxable
income
as
the
amount
of
$16,741.63
was
not
included
in
computing
his
income
pursuant
to
the
Income
Tax
Act.
—
The
Respondent
relied,
inter
alia,
upon
subsection
2(3)
and
paragraph
115(1)(f)
of
the
Income
Tax
Act,
R.S.C.
1952,
Chapter
148,
as
amended
(the
‘Act’).
—
Of
the
Appellant’s
world
income
of
$42,141.63,
only
$25,400,
or
60.27%,
was
included
in
computing
his
taxable
income
earned
in
Canada
for
the
year,
so
he
was
precluded
by
paragraph
115(1)(f)
from
taking
other
deductions
for
the
purpose
of
computing
taxable
income.
In
testimony
Mr.
Wood
noted
that
his
Canadian
income
had
been
about
$30,000,
and
his
U.S.
income
about
$12,500
rather
than
the
amounts
refer-
enced
above
by
the
respondent.
Counsel
for
the
Minister
did
not
disagree
with
these
changes
but
commented
that
they
did
not
affect
the
basis
for
the
disallowance.
Mr.
Wood's
position
was
that
.
.
his
income
from
nonCanadian
sources
was
an
insignificant
part,
since
the
Canadian
source
income
was
from
full-time
employment
and
represented
the
majority
of
his
world
wide
income".
Both
parties
noted
for
the
Court
that
there
did
not
appear
to
be
any
recent
jurisprudence
dealing
directly
with
the
term
"substantially
all”
as
it
is
found
in
paragraph
115(1)(f)
of
the
Act:
Section
115.
Non-residents’
taxable
income
earned
in
Canada.
(1)
For
the
purpose
of
this
Act,
a
non-resident
person's
taxable
income
earned
in
Canada
for
a
taxation
year
is
the
amount
of
his
income
for
the
year
that
would
be
determined
under
section
3
if
(f)
where
all
or
substantially
all
of
the
non-resident
person's
income
for
the
year
is
included
in
computing
his
taxable
income
earned
in
Canada
for
the
year,
such
of
the
other
deductions
permitted
for
the
purpose
of
computing
taxable
income
as
may
reasonably
be
considered
wholly
applicable.
Paragraph
(d)
and
(e)
of
subsection
115(1)
provide
for
deductions
from
income
of
a
non-resident
of
certain
amounts
found
under
section
110
and
section
111
of
the
Act.
It
was
the
understanding
of
counsel
for
the
Minister
(and
agreed
to
by
the
appellant)
that
except
for
the
dispute
over
the
term
“substantially
all”
(supra)
Mr.
Wood
would
be
permitted
the
deduction
he
claimed
by
virtue
of
the
words:
(e)
such
of
the
deductions
from
income
permitted
by
section
111
as
may
reasonably
be
considered
to
be
applicable
to
the
duties
of
an
office
or
employment
performed
by
him
in
Canada,
a
business
carried
on
by
him
in
Canada
or
a
disposition
of
property,
any
profit
or
gain
on
which
would
have
been
required
by
this
subsection
to
be
included
in
computing
his
taxable
income
earned
in
Canada,
and
(f)
where
all
or
substantially
all
of
the
non-resident
person's
income
for
the
year
is
included
in
computing
his
taxable
income
earned
in
Canada
for
the
year,
such
of
the
other
deductions
permitted
for
the
purpose
of
computing
taxable
income
as
may
reasonably
be
considered
wholly
applicable.
That
view
of
the
section,
presupposes
that
the
"taxable
income"
referred
to
is
a
reflection
of
the
definition
of
“taxable
income"
given
by
subsection
2(2)
of
the
Act,
dealing
with
"resident"
persons
as
opposed
to
the
taxable
income"
as
outlined
in
subsection
2(3)
of
the
Act
dealing
with
"non-resident"
persons:
Section
2.
Tax
payable
by
persons
resident
in
Canada.
(1)
An
income
tax
shall
be
paid
as
hereinafter
required
upon
the
taxable
income
for
each
taxation
year
of
every
person
resident
in
Canada
at
any
time
in
the
year.
Section
2(2)
(2)
Taxable
income
defined.
The
taxable
income
of
a
taxpayer
for
a
taxation
year
is
his
income
for
the
year
plus
the
additions
and
minus
the
deductions
permitted
by
Division
C.
Section
2(3)
(3)
Tax
payable
by
non-resident
persons.
Where
a
person
who
is
not
taxable
under
subsection
(1)
for
a
taxation
year
(a)
was
employed
in
Canada,
(b)
carried
on
a
business
in
Canada,
or
(c)
disposed
of
a
taxable
Canadian
property,
at
any
time
in
the
year
or
a
previous
year,
an
income
tax
shall
be
paid
as
hereinafter
required
upon
his
taxable
income
earned
in
Canada
for
the
year
determined
in
accordance
with
Division
D.
One
could
assert
that
if
indeed
the
intention
of
the
drafters
of
the
Act
was
to
make
available
to
“non-residents”,
(under
the
conditions
precluded
in
paragraph
115(1
)(f)
of
the
Act
the
personal
exemption
under
section
109
of
the
Act,
this
might
have
been
so
stated
in
view
of
the
specific
reference
to
sections
110
and
111.
This
is
particularly
apt,
since
as
I
read
Interpretation
Bulletin
171
(Special
Release)
dated
September
4,
1985,
the
only
other
section
of
the
Act
to
which
reference
is
made
is
section
109.
Whether
the
wording
of
paragraph
115(1)(f)
of
the
Act
(supra)
serves
the
Minister
for
assessment
purposes
in
the
manner
expressed
by
I.T.-171
(supra)
and
used
in
this
appeal,
(as
providing
for
“personal
exemptions
from
section
109)
may
be
a
moot
point,
and
while
it
entered
into
the
discussions
held
at
this
hearing
of
the
appeal,
it
will
be
left
for
review,
if
necessary,
at
another
time.
This
Court
will
simply
address
the
question
of
whether
the
situation
as
described
by
Mr.
Wood
qualifies
under
the
term
“substantially
all”
from
paragraph
115(1
)(f)
of
the
Act.
The
Minister's
rule
(from
I.T.-171
(supra))
is
that
the
Canadian
income
should
be
at
least
90
per
cent
of
total
income
—
the
“90
per
cent
rule”.
Obviously
that
is
just
a
departmental
assessing
policy,
and
while
arbitrary
is
undoubtedly
a
useful
and
functional
mechanism
in
dealing
with
a
difficult
section
of
the
Act.
I
would
think
the
Minister
might
be
hard-pressed
to
refuse
a
claim
where
the
percentage
was
89
per
cent,
maybe
even
85
per
cent
or
80
per
cent
or
lower
—
and
that
brings
up
this
taxpayer's
position
which
ends
up
to
be
about
70
per
cent.
($30,000
out
of
$42,500).*
Clearly
the
term
“substantially
all”
does
not
lend
itself
to
a
simple
mathematical
formula.
Further
it
would
seem
to
me
that
any
particular
definition
of
“substantially”
would
be
only
valid
with
reference
to
the
specific
context
in
which
it
is
found.
In
this
case,
if
it
be
correct
that
qualifying
under
paragraph
115(1
)(f)
of
the
Act,
entitles
the
taxpayer
to
the
personal
exemption
at
issue,
then
the
options
available
to
him
to
attain
such
qualifications
with
regard
to
declaring
his
income
in
Canada
are
“all”
or
“substantially
all”.
Obviously,
if
the
taxpayer
desperately
wanted
to
obtain
the
“personal
exemption”
he
claims
he
has
the
option
of
declaring
“all”
of
his
income
in
the
preparation
of
his
Canadian
tax
return.
As
I
read
the
relevant
section,
the
Minister
then
could
have
no
quarrel
with
the
return.
From
that
I
would
deduce
that
when
a
taxpayer
chooses
not
to
declare
“all”
his
income
in
filing
his
Canadian
return,
the
non-declared
portion
must
be
so
insignificant
that
neither
its
inclusion
or
exclusion
would
make
a
“substantial”
difference
in
the
income
tax
return
in
Canada.
One
might
even
postulate
that
the
undisclosed
(foreign)
income,
of
itself,
might
not
be
sufficient
to
even
require
that
the
individual
file
a
tax
return
in
the
foreign
country.
While
that
view
does
not
place
any
mathematical
level
on
the
term
“substantially
all”,
in
my
opinion
it
comes
much
closer
to
the
description
accorded
it
by
counsel
for
the
Minister
in
this
appeal
—
“small,
unrelated
amounts,
such
as
interest
etc.”
rather
than
the
Minister’s
policy
of
90
per
cent,
and
certainly
far
removed
from
the
$12,500
out
of
$42,500
at
issue
in
the
instant
case.
It
can
readily
be
determined
that
the
“foreign”
income
has
provided
a
“substantial”
financial
benefit
to
the
taxpayer,
which
would
be
still
further
enhanced
by
the
benefit
accruing
as
a
result
of
the
personal
exemption
sought,
to
the
taxpayer
in
this
appeal.
Under
these
circumstances
the
provi-
sions
of
the
Act
that
“substantially
all”
of
the
non-resident
person's
income
be
included
have
not
been
met
in
my
view.
The
appeal
is
dismissed.
Appeal
dismissed.
