The
Associate
Chief
Justice:—The
issue
in
this
appeal
is
whether
the
defendant
is
entitled,
under
Arctile
VIII
A
of
the
Canada-United
States
Reciprocal
Tax
Convention,
to
exemption
from
Canadian
income
taxation
in
respect
of
his
income
from
teaching
as
a
professor
at
St
Thomas
University
in
Fredericton,
New
Brunswick
for
the
period
from
January
1,
1970
to
June
30,
1970.
By
statute,
the
Convention
has
the
force
of
law.
Article
VIII
A
provides:
Article
VIII
A.
A
professor
or
teacher
who
is
a
resident
of
one
of
the
contracting
States
and
who
temporarily
visits
the
other
contracting
State
for
the
purpose
of
teaching,
for
a
period
not
exceeding
two
years,
at
a
university,
college,
school
or
other
educational
institution
in
such
other
State,
shall
be
exempted
by
such
other
State
from
tax
on
his
remuneration
for
such
teaching
for
such
period.
The
defendant
is
a
professor
of
English
literature.
He
and
his
wife
are
natural-born
citizens
of
the
United
States
and
had
resided
there
until
they
came
to
Canada
on
September
10,
1968,
when
the
defendant
took
up
a
position
as
a
professor
at
St
Thomas
University.
On
coming
to
Canada,
the
defendant
gave
up
his
rented
apartment
in
the
United
States
and
moved
his
household
effects
to
Fredericton
where
he
and
his
family
occupied
an
apartment
for
three
months
and
thereafter
a
house,
both
of
which
were
rented
on
a
month-to-month
basis.
They
entered
Canada
as
landed
immigrants
and
they
had
no
property
in
the
United
States
other
than
a
bank
account
in
Chicago,
but
they
still
had
family
relations
in
the
United
States
and
they
went
there
to
visit
from
time
to
time.
The
arrangements
for
his
position
as
a
teacher
at
St
Thomas
University
had
been
made
in
February
of
1968.
The
correspondence
indicates
that
the
defendant
had
sought
employment
for
the
academic
year
1968-69
but
the
arrangement
disclosed
by
the
letters
does
not
show
clearly
for
how
long
the
defendant
was
to
be
employed.
He
expected
it
to
be
for
two
terms
since
it
would
be
necessary
for
the
University
to
begin
looking
for
a
replacement
for
him
for
the
next
academic
year
not
long
after
his
arrival
if
he
was
to
be
there
for
only
one
academic
year
and
he
thought
it
unlikely
that
the
University
would
do
that.
On
the
other
hand,
when
he
arrived
he
found
that
the
University
did
not
consider
itself
under
any
obligation
to
continue
the
employment
for
a
second
year.
In
fact,
it
was
continued
for
a
second
year.
Had
the
employment
ended
at
the
end
of
the
second
academic
year,
it
would
have
been
for
a
period
not
exceeding
two
years.
But
in
March
1970
the
defendant,
after
having
made
inquiries
as
to
teaching
opportunities
elsewhere
and
having
found
that
teaching
jobs
were
becoming
hard
to
find,
accepted
an
offer
dated
February
20,
1970
of
permanent
employment
with
St
Thomas
University.
Under
this
arrangement
he
continued
teaching
there
throughout
the
remainder
of
197G
and
he
has
taught
there
ever
since,
save
for
a
year
of
sabbatical
leave
which
he
spent
in
Germany.
After
some
years,
he
was
granted
what
is
Known
as
tenure.
When
he
came
to
Canada,
the
defendant’s
intention
was
to
stay
for
only
two
years
or
two
academic
terms.
He
did
not
expect
to
like
teaching
at
St
Thomas
University
and
expected
to
return
to
the
United
States
after
the
two
terms.
But
he
and
his
wife
were
interested
in
living
elsewhere
than
in
the
American
Midwest
where
both
of
them
had
lived
up
to
that
time
and,
as
the
work
load
as
a
teacher
at
St
Thomas
would
be
less
than
he
had
experienced
in
the
United
States,
he
saw
the
proposal
as
an
opportunity
to
do
some
writing,
in
addition
to
teaching,
and
thus
to
enhance
his
reputation
and
his
chances
for
employment
at
a
more
prestigious
institution
in
the
United
States.
He
still
had
this
in
mind
when
making
inquiries
for
other
opportunities
before
he
accepted
the
University’s
offer
of
February
20,
1970
of
permanent
employment.
The
defendant
was
not
taxed
in
Canada
on
his
income
from
teaching
at
St
Thomas
University
for
the
period
from
September
10,
1968
to
December
30,
1968,
nor
for
the
year
1969.
With
respect
to
1970,
however,
the
Minister
took
the
position
that,
since
the
defendant
had
remained
in
Canada
after
June
30,
1970
and
had
continued
to
teach
at
St
Thomas
University
under
an
extension
of
his
original
2-year
employment,
he
was
not
entitled
to
exemption
in
respect
of
his
income
from
teaching
for
any
part
of
the
year
and
he
assessed
the
defendant
accordingly.
The
Tax
Review
Board,
following
the
judgments
of
the
Supreme
Court
and
the
Federal
Court
of
Appeal
in
Stickel
v
MNR,
[1973]
FC
259;
[1973]
CTC
202;
73
DTC
5178;
[1975]
2
SCR
233;
[1974]
CTC
416;
74
DTC
6268,
allowed
the
defendant’s
appeal.
In
the
Stickel
case,
the
taxpayer,
a
citizen
of
the
United
States,
who
had
lived
and
worked
there
prior
to
coming
to
Canada
in
July
1967
to
begin
a
2-year
teaching
contract
with
the
University
of
Alberta
ending
on
June
30,
1969,
did
not
return
to
the
United
States
until
March
1970
and,
in
the
meantime,
he
held
two
other
non-teaching
jobs.
On
the
particular
facts,
he
was
held
to
be
a
resident
of
the
United
States
within
the
meaning
of
Arcticle
VIII
A
of
the
Convention,
that
he
had
been
temporarily
visiting
in
Canada
for
the
purpose
of
teaching
for
a
period
not
exceeding
two
years
at
a
university
and
that
he
was
entitled
to
the
exemption
notwithstanding
the
fact
that
he
had
been
in
Canada
more
than
two
years
and
had
not
been
taxed
in
the
United
States
on
his
teaching
income
earned
in
Canada.
With
respect
to
the
interpretation
of
Article
VIII
A,
the
Chief
Justice
of
the
Federal
Court
said
at
page
261
[203,
5179]:
The
question
of
interpretation
turns
on
whether
the
words
“for
a
period
not
exceeding
two
years’’
modify
the
word
“visits’’
or
are
an
integral
portion
of
the
expression
“for
the
purpose
of
teaching
.
.
.
at
a
university
.
.
.’’.
Once
it
is
appreciated
that
the
words
that
constitute
the
second
condition
precedent
to
the
application
of
Article
VIII
A
are
“Who
temporarily
visits
the
other
contracting
State
for
the
purpose
of
teaching,
for
a
period
not
exceeding
two
years,
at
a
university
.
.
.”
and
not
merely
“who
temporarily
visits
the
other
contracting
State
for
the
purpose
of
teaching,
for
a
period
not
exceeding
two
years’’,
we
are
all
agreed
that
the
words
“for
a
period
not
exceeding
two
years’’
are
an
integral
part
of
the
expression
“for
the
purpose
of
teaching
.
.
.
at
a
university
.
.
.’’
and
do
not
relate
to
the
period
of
the
visit
as
revealed
by
the
actual
events.
In
our
view,
the
balance
of
probability
on
the
evidence
is
that
the
appellant,
who
was
resident
in
the
United
States,
had
given
some
thought
to
the
possibility
of
moving
to
Canada
before
he
obtained
an
opportunity
to
take
a
two-year
term
appointment
at
the
University
of
Alberta,
that
he
discussed
the
project
with
his
family,
who
were
not
enthusiastic
about
the
prospect
of
a
permanent
move
to
Canada,
and
that
they
reached
a
joint
decision
to
go
to
Canada
for
the
two-year
appointment
only
but
on
the
understanding
that
during
that
two-year
period
they
might
reconsider
the
possibility
of
making
their
permanent
home
in
Canada.
On
those
facts,
having
regard
to
the
necessity
of
interpreting
the
words
“temporarily
visits’’
as
including
visiting
for
the
purpose
of
teaching
for
a
period
as
long
as
two
years,
we
are
agreed
that
the
appellant
was
a
person
who
temporarily
visited
Canada
for
the
purpose
of
teaching
at
a
university
for
a
period
not
exceeding
two
years.
With
regard
to
the
question
of
residence,
the
Chief
Justice
also
said
at
page
262
[204,
5179]:
A
more
difficult
question
is
whether
the
appellant
was
‘‘a
resident’’
of
the
United
States
at
the
time
contemplated
by
Article
VIII
A.
The
respondent’s
position
is
that
this
contemplates
residence
in
the
sense
given
to
that
word
when
it
is
a
basis
for
liability
to
income
tax
and
that
it
is
a
condition
of
the
article
that
a
person
must
have
been
so
resident
throughout
the
period
of
the
exemption.
If
that
be
so,
it
is
difficult
to
envisage
what
tax
relief
is
accorded
by
Article
VIII
A
in
the
case
of
professors
and
teachers
that
would
not
otherwise
be
available
in
the
case
of
all
taxpayers
by
virtue
of
the
foreign
tax
credit
provisions
which
are,
it
is
believed,
also
contemplated
by
the
Tax
Convention
in
question.
We
do
not
find
it
expedient
to
attempt
to
formulate
any
definition
of
what
is
implied
by
the
words
“is
a
resident’’
in
their
context
in
Article
VIII
A.
No
matter
how
narrowly
the
expression
is
construed,
it
would
certainly
embrace
the
appellant
if
he
had
been
sufficiently
affluent
and
hard
hearted
to
have
left
his
family
in
a
family
home
in
the
United
States
for
the
two-year
period
and
to
have
continued
to
incur
the
expense
of
maintaining
his
community
and
social
relationships
there
during
the
period
of
his
two
years’
absence.
This
would
be
so
in
the
case
of
a
mariner
or
soldier
who
had
to
absent
himself
from
his
home
for
such
a
period
and
the
work
performed
while
away
does
not
constitute
a
relevant
distinction.
If
that
would
have
been
so
in
the
case
of
a
person
who
could
afford
to
maintain
nis
family
in
the
United
States
while
away,
and
was
willing
to
do,
we
are
of
the
view
that
a
person
who
is
on
a
two-year
“temporary”
visit
to
teach
in
a
foreign
university
was
equally
a
“resident”
of
his
native
land
for
the
purposes
of
Article
VIII
A
even
though
he
took
his
family
with
him
and
did
not
continue
to
incur
the
expense
of
maintaining
his
community
and
social
relationships
in
his
native
land.
Both
of
these
views
were
supported
by
the
Supreme
Court.
The
principal
difference
relied
on
by
the
plaintiff
as
distinguishing
the
Stickel
case
from
the
present
was
that
the
defendant
did
not
cease
teaching
at
the
end
of
the
2-year
term
but
continued
to
do
so
under
the
arrangement
which
continued
his
employment
beyond
that
period.
That
difference
by
itself,
in
my
view,
would
not
lead
to
any
difference
in
the
result.
The
relevant
time
for
the
purpose
of
applying
Article
VIII
A,
as
I
see
it,
is
when
the
income
that
is
in
question
is
being
earned
and
what
the
defendant
did
after
the
end
of
the
2-year
period
would
not,
in
my
opinion,
operate
to
deprive
him
of
any
exemption
to
which
he
had
become
entitled
in
respect
of
his
earnings
during
the
2-year
period.
On
the
facts
as
I
have
outlined
them,
I
am
satisfied
that
the
defendant,
from
the
time
he
came
to
Canada
in
September
1968
throughout
the
remainder
of
that
year
and
all
of
1969,
was
temporarily
visiting
Canada
for
the
purpose
of
teaching
for
a
period
not
exceeding
two
years
at
a
university
within
the
meaning
of
Article
VIII
A.
True,
he
had
entered
as
a
landed
immigrant.
But
I
do
not
regard
that,
or
the
inference
that
it
suggests,
as
outweighing
the
evidence
of
his
expectation
as
to
how
long
he
would
stay
and
of
his
plans
for
his
future.
He
did
not
regard
his
sojourn
in
this
country
as
permanent
and
nothing
in
the
contract
of
employment
he
had
at
that
time
is,
in
my
view,
inconsistent
with
what
he
had
in
mind.
I
also
find
that
he
continued
to
be
resident
in
the
United
States
within
the
meaning
of
Article
VIII
A
in
the
sense
in
which
it
was
considered
that
the
taxpayer
in
the
Shekel
case
continued
to
be
resident
in
the
United
States.
On
the
basis
of
these
conclusions,
it
follows
that
the
defendant
would
qualify
for
exemption
in
the
period
here
in
question
for
the
months
of
January
and
February
1970,
since
in
those
months
there
was
no
change
in
the
purpose
for
which
he
was
temporarily
visiting
Canada.
But
it
appears
to
me
that
the
same
cannot
be
said
of
his
purpose
when,
in
or
about
March
1970,
he
accepted
the
University’s
offer
of
February
20,
1970
to
continue
his
employment
on
a
permanent
basis.
From
that
point
on,
while
conceivably
it
might
still
be
said
that
he
was
temporarily
visiting
Canada
for
the
purpose
of
teaching
at
a
university,
it
could,
as
I
see
it,
no
longer
be
said
that
such
temporary
visiting
was
for
the
purpose
of
teaching
for
a
term
not
exceeding
two
years.
The
purpose
then,
as
I
see
it,
was
that
of
teaching
beyond
the
two
years
and
indefinitely
thereafter.
From
the
time
when
he
accepted
the
offer,
therefore,
which
I
take
as
at
the
beginning
of
March
1970,
he
was
no
longer
qualified
for
or
entitled
to
exemption
under
Article
VIII
A.
In
the
course
of
argument,
counsel
for
the
Crown
referred
to
two
cases
in
the
Tax
Review
Board,
Wyatt
v
MNR,
[1975]
CTC
2055;
75
DTC
72,
and
Shihadeh
v
MNR,
[1975]
CTC
2116;
75
DTC
74,
in
both
of
which
a
conclusion
which
appears
to
be
at
variance
with
that
of
the
Tax
Review
Board
in
the
present
case
and
at
variance
as
well
with
the
view
I
have
expressed
was
reached.
As
the
Wyatt
case
arose
on
the
exempting
provision
of
the
Canada-United
Kingdom
Income
Tax
Agreement,
I
need
not
comment
on
it.
On
the
other
hand,
the
Shihadeh
Case
arose
on
the
exemption
provided
by
Article
VIII
A
of
the
Canada-
United
States
Reciprocal
Tax
Convention
and
is
in
point
but,
with
respect,
it
appears
to
me
to
be
at
variance
with
the
judgment
in
the
Stickel
case
and
I
do
not
think
I
should
adopt
or
follow
it.
Before
parting
with
the
matter,
I
should
add
a
comment
regarding
the
pleadings.
During
the
argument,
a
question
arose
as
to
whether
any
basis
had
been
pleaded
by
the
Crown
for
disallowing
the
exemption
other
than
the
bare
fact
that
the
defendant
in
1970
had
then
taught
in
Canada
for
more
than
two
years.
The
fact
which
I
have
held
to
be
determinative,
that
is
to
say,
the
change
of
purpose
of
the
defendant’s
visit,
was
not
expressly
alleged.
But
it
was
alleged
in
paragraphs
5,
6
and
7
of
the
statement
of
claim,
and
admitted
in
the
defence,
that
the
defendant
entered
Canada
on
September
10,
1968
and
immediately
took
up
a
position
as
a
professor
of
literature
at
St
Thomas
University
and
that,
in
or
about
the
month
of
March
1970,
he
accepted
a
position
which
continued
his
employment
as
a
professor
of
literature
at
St
Thomas
University.
The
plaintiff
then
asserted
reliance
on
sections
2,
3
and
5
of
the
Income
Tax
Act,
RSC
1952,
c
148,
and
Article
VIIT
A
of
the
Convention.
Apart
from
admissions,
the
defence
consisted
chiefly
of
denials.
It
included
a
denial
that
the
statutory
provisions
referred
to
in
the
statement
of
claim
rendered
him
liable
to
taxation
and
purported
to
put
the
plaintiff
“to
the
strict
proof
thereof’’.
At
the
trial,
however,
counsel
for
the
defendant
in
his
Opening
statement
took
the
position
that
the
defendant
fell
within
Article
VIII
A
of
the
Convention
and
was
in
fact
exempt
from
January
1
to
June
30,
1970,
and
he
offered
evidence
to
establish
the
defendant’s
right
to
the
exemption.
In
the
view
I
take
of
it,
while
the
plaintiff’s
case
might
have
been
more
particularly
pleaded,
the
substance
of
it
is
to
be
found
in
the
allegations
that
the
defendant
was
employed
in
Canada
in
the
relevant
period
and
thereby
earned
income.
That,
as
I
see
it,
renders
the
defendant
liable
to
taxation
unless
he
can
bring
himself
within
an
exempting
provision.
For
that
purpose,
it
was,
I
think,
incumbent
on
him
to
state
in
his
defence
and
prove
at
the
trial
facts
entitling
him
to
exemption
in
respect
of
the
period
in
question.*
I
do
not
think,
therefore,
that
the
objection
that
the
plaintiff
did
not
adequately
plead
facts
disentitling
the
defendant
to
exemption
can
succeed
and,
in
any
event,
I
do
not
think
the
defendant
was
in
any
way
prejudiced
by
the
lack
of
any
such
pleading.
The
appeal
accordingly
fails
with
respect
to
the
defendant’s
income
from
teaching
in
January
and
February
1970
and
succeeds
with
respect
to
his
income
from
teaching
in
March,
April,
May
and
June
1970.
Under
subsection
178(2)
of
the
Income
Tax
Act,
RSC
1952,
c
148,
as
amended
by
section
1,
c
63,
SC
1970-71-72,
the
defendant
is
entitled
to
be
paid
all
reasonable
and
proper
costs
in
connection
with
the
appeal.
