THE
CHIEF
Justice
(Judson,
J.,
concurs)
:—This
is
an
appeal
against
a
judgment
of
the
Exchequer
Court
dismissing
the
appeal
of
the
appellant,
North
Bay
Mica
Company
Limited,
from
the
decision
by
the
Minister
of
National
Revenue
confirming
the
reassessment
of
the
appellant
for
the
taxation
year
1951
under
the
Income
Tax
Act.
The
point
in
issue
is
whether
the
appellant
was
correct
in
not
including
in
the
computation
of
its
income
for
that
year
the
income
derived
by
it
from
the
operation
of
a
mica
mine
formerly
owned
and
operated
by
Purdy
Mica
Mines
Limited.
The
section
of
the
Act
as
applicable
to
the
taxation
year
1951
is
Section
74:
“74.
(1)
Where
a
corporation
establishes
that
a
mine
was
(a)
a
metalliferous
mine,
or
(b)
an
industrial
mineral
mine
certified
by
the
Minister
of
Mines
and
Technical
Surveys
to
have
been
operating
on
mineral
deposits
(other
than
bedded
deposits
such
as
building
stone),
that
came
into
production
of
ore
during
the
calendar
years
1946
to
1954,
inclusive,
income
derived
from
the
operation
of
the
mine
during
the
period
of
36
months
commencing
with
the
day
on
which
the
mine
came
into
production
(other
than
any
portion
thereof
in
the
year
1946)
shall,
subject
to
prescribed
conditions,
not
be
included
in
computing
the
income
of
the
corporation.
(2)
In
this
section,
‘production’
means
production
in
reasonable
commercial
quantities.’’
We
are
not
concerned
with
a
metalliferous
mine,
but
with
an
industrial
mine
which,
it
is
agreed,
was
certified
by
the
Minister
of
Mines
and
Technical
Surveys
to
have
been
operating
on
mineral
deposits
(other
than
bedded
deposits
such
as
building
stone).
The
dispute
is
whether
the
income
of
the
appellant
from
the
operation
of
this
mine
was
derived
from
a
mine
that
came
into
production
of
ore
in
reasonable
quantities
during
the
calendar
years
1946
to
1950.
The
learned
trial
judge
dealt
with
the
history
of
certain
provisions
of
the
Income
War
Tax
Act
and
the
Income
Tax
Act,
and
while
counsel
for
the
appellant
disavowed
any
suggestion
that
he
was
relying
in
any
way
upon
such
history,
it
does
not
detract
from
the
conclusion
reached
in
the
Exchequer
Court.
Counsel
did
refer
to
a
letter
of
August
9,
1951,
written
on
behalf
of
the
Director
General,
Corporation
Assessments
Branch,
to
the
appellant’s
solicitor,
but
I
agree
with
Mr.
Jackett
that
if
what
is
therein
stated
is
meant
to
apply
to
Section
74
it
cannot
affect
what
the
Court
deems
to
be
the
proper
construction
of
that
provision.
From
October
1942,
Purdy
Mica
Mines
Limited
had
successfully
operated
a
mica
mine
on
certain
mining
claims
owned
by
it
in
the
Township
of
Mattawan,
in
the
Province
of
Ontario.
After
obtaining
reports
from
certain
geologists,
the
Purdy
Company
decided
that
it
would
not
proceed
with
any
further
investigations
into
the
possibilities
of
securing
additional
mica.
In
October
1945
it
ceased
operations
and
from
that
time
to
1949
there
was
no
activity
of
any
kind
by
it
on
the
property.
James
J.
Kenmey,
having
become
interested
in
the
claims,
made
a
thorough
investigation,
as
a
result
of
which
a
lease
was
first
granted
to
his
associate,
Paul
A.
McDermott,
and
subsequently
assigned
to
Kenmey
and
two
others
who
carried
on
business
in
partnership
under
the
name
of
North
Bay
Mica
Company.
This
partnership
proceeded
to
operate
on
the
leased
claims
in
1949.
The
appellant
was
incorporated
under
The
Ontario
Companies
Act
by
letters
patent
of
January
27,
1950,
and
continued
the
operations.
By
arrangement
the
claims
were
sold
to
the
appellant
by
the
Purdy
Company
which
received
certain
payments
in
cash
and
a
10
per
cent
stock
interest
in
the
appellant
company.
The
word
‘‘mine’’
in
Section
74
should
be
construed
as
denoting
a
physical
thing.
It
was
argued,
however,
that
the
Purdy
Company
had
abandoned
the
mine
and
that,
although
the
work
done
by
the
appellant
company
is
on
the
same
mining
claims,
what
Kenmey
and
his
associates
commenced
and
the
appellant
continued
was
a
different
mine
and,
therefore,
cannot
be
said
to
have
come
into
production
as
early
as
1946.
The
evidence
as
to
what
occurred
generally
is
uncontradicted
and
is
set
out
by
the
trial
judge.
The
following
references
are,
however,
of
particular
importance.
In
cross-examination
Mr.
Kenmey
admitted
that
with
respect
to
pit
No.
3
(the
important
one
in
the
operations
of
the
Purdy
Company)
he
found
stringers
leading
off
into
the
wall
rock
and
that
the
Purdy
Company
had
exposed
another
dyke
but
had
done
nothing
about
it.
He
continued:
‘‘
Well
the
stringers
which
led
off
into
the
wall
rock,
in
my
impression,
was,
in
fact,
another
dyke
that
they
had
done
nothing
about.
Those
stringers
were,
in
fact
another
—
indications
of
another
dyke
—
I
will
put
it
that
way’’.
The
truth
of
the
matter
appears
to
be
that
as
expressed
by
the
witness
George
B.
Langford,
when
he
testified
that
the
Purdy
Company
“mined
the
ore
which
they
could
see
from
day
to
day
and
did
not
spend
the
time
or
money
estimated
to
develop
ore
for
the
mining
operations
of
the
future.
They
did
not,
until
they
came
to
the
end
of
their
ore
and
then
they
undertook
some
rather
extensive
drilling
operations
to
try
and
find
some
more
pegmatite”.
That
drilling
did
not
find
any
ore
but
Mr.
Kenmey’s
work
did.
The
mine
operated
in
1950-51
by
the
appellant
is
the
same
mine
as
that
operated
by
the
Purdy
Company
down
to
1945.
The
mine
came
into
production
of
ore
in
October
1942
and
therefore
it
cannot
be
said
that
it
came
into
production
as
late
as
1946,
the
first
year
mentioned
in
Section
74.
The
appeal
should
be
dismissed
with
costs.
CARTWRIGHT,
J.
(Martland,
J.,
concurs)
:—The
relevant
facts
out
of
which
this
appeal
arises
are
undisputed
and
are
stated
in
the
reasons
of
the
Chief
Justices.
I
wish,
however,
to
emphasize
two
matters:
(i)
that
in
1945
Purdy
Mica
Mines
Limited
had
given
up
all
thought
of
carrying
on
any
further
mining
operations
on
the
claims
later
required
by
the
appellant
and
had
removed
its
buildings
and
machinery;
and,
(ii)
that,
while
the
lens
of
mica
discovered
and
worked
by
the
appellant
was
in
close
proximity
to
one
of
those
worked
by
Purdy
Mica
Mines
Limited,
the
last
mentioned
company
had
failed
to
discover
it
and
was
unaware
of
its
existence.
The
question
before
us
turns
upon
the
construction
of
Section
74
of
the
Income
Tax
Act,
which
is
set
out
in
the
reasons
of
the
Chief
Justice.
For
the
appellant
it
is
contended
that
the
word
‘mine”
as
used
in
clause
(b)
of
Section
74(1)
means
not
‘‘a
portion
of
the
earth
containing
mineral
deposits’’
but
rather
‘‘a
mining
concern
taken
as
a
whole,
comprising
mineral
deposits.
workings,
equipment
and
machinery,
capable
of
producing
ore’’.
Support
for
this
contention
is
sought
in
the
circumstances
that
if
mine
’’
has
the
first
of
the
two
suggested
meanings,
then,
(i)
the
phrase
“certified
.
.
.
to
have
been
operating
on
mineral
deposits”
is
inapt
as
it
presupposes
an
entity
capable
of
carrying
on
operations;
and
(ii)
the
draftsman
should
have
substituted
for
the
clause
‘‘that
came
into
production’’
the
clause
‘‘that
was
brought
into
production’’.
From
this
the
appellant
goes
on
to
argue
that
the
‘‘mine’’
of
the
appellant
is
one
entirely
different
from
the
“mine”
of
Purdy
Mica
Mines
Limited.
I
incline
to
the
view
that
this
contention
is
sound;
but,
be
that
as
it
may,
the
facts
appear
to
me
to
bring
the
claim
of
the
appellant
within
the
plain
words
of
the
section.
The
appellant
is
a
corporation.
It
has
established
that
the
mine
from
the
operation
of
which
it
derived
its
income
for
the
year
1951
was
an
industrial
mine
certified
by
the
Minister
of
Mines
and
Technical
Surveys
to
have
been
operating
on
mineral
deposits
(other
than
bedded
deposits
such
as
building
stone)
that
came
into
production
of
ore
in
reasonable
commercial
quantities
during
the
year
1950.
The
argument
of
the
respondent
is,
in
effect,
that
this
would
be
so
but
for
the
fact
that
some
years
prior
to
1946
the
same
mine,
then
operated
by
Purdy
Mica
Mines
Limited,
came
into
production
of
ore
in
reasonable
commercial
quantities.
That
this
would
be
a
sufficient
answer
if
the
same
property,
to
use
a
neutral
word,
had
been
continuously
operated
as
an
industrial
mine
and
had
merely
changed
hands
I
do
not
doubt;
but
it
appears
to
me
that
in
the
interval
between
the
cessation
of
operations
by
Purdy
Mica
Mines
Limited
and
the
commencement
of
those
of
the
appellant
the
property
had
lost
the
character
of
a
mine.
What
the
appellant
acquired
was
not
a
mine
but
a
derelict
and
abandoned
property
which
it
hoped
to
develop
into
a
mine.
The
submission
of
the
respondent
is
that
if
an
industrial
mine
has
at
any
time
been
operated
on
a
particular
piece
of
property
and
been
brought
into
production
of
ore
in
commercial
quantities,
then,
notwithstanding
the
fact
that
its
operation
has
been
completely
and
finally
abandoned,
no
industrial
mine
subsequently
operated
on
the
same
piece
of
property,
no
matter
how
long
thereafter,
can
come
within
the
intendment
of
Section
74.
It
appears
to
me
that
the
construction
for
which
the
respondent
contends
necessitates
adding
to
the
section
some
such
words
as
those
I
have
italicized
so
as
to
make
it
read:
‘‘that
came
into
production
of
ore
for
the
first
time
during
the
calendar
years
1946
to
1954
inclusive’’
or
‘‘that
first
came
into
production
.
.
.
??.
If
on
consideration
of
the
words
of
the
section
in
their
ordinary
sense,
their
true
meaning
appeared
doubtful,
as
I
think
it
does
not,
it
would
be
proper
to
inquire
what
was
the
object
which
Parliament
had
in
view
as
appearing
from
the
circumstances
with
reference
to
which
the
words
were
used.
The
object
was
clearly
to
encourage
the
development
of
productive
industrial
mines
of
the
sort
described
in
the
section.
This
object
would
not
be
rendered
less
desirable
by
the
circumstance
that
at
some
earlier
time,
ore
had
been
produced
from
the
same
piece
of
property.
The
respondent
relied
on
the
following,
often
quoted,
passage
in
the
judgment
of
Ritchie
C.
J.
in
Wylie
v.
City
of
Montreal,
(1885),
12
S.C.R.
384
at
p.
386:
‘
I
am
quite
willing
to
admit
that
the
intention
to
exempt
must
be
expressed
in
clear
unambiguous
language;
that
taxation
is
the
rule
and
exemption
the
exception,
and
therefore
to
be
strictly
construed
;’’
In
my
opinion,
resort
can
properly
be
had
to
the
principle
stated
in
this
passage
only
if
the
Court
is
unable
to
determine
the
meaning
of
the
words
it
is
called
upon
to
interpret
after
calling
in
aid
all
relevant
rules
of
construction.
I
would
allow
the
appeal,
set
aside
the
judgment
below
and
the
amended
assessment
and
restore
the
original
assessment
of
September
21,
1951,
under
which
no
tax
was
levied.
The
appellant
is
entitled
to
its
costs
in
the
Exchequer
Court
and
in
this
Court.
ABBOTT,
J.:—I
would
allow
the
appeal
and
dispose
of
the
matter
as
proposed
by
my
brother
Cartwright.
Judgment
accordingly.
