The
Chief
Justice
(judgment
delivered
from
the
Bench):—This
is
an
appeal
from
a
judgment
of
the
Trial
Division
dismissing
an
appeal
from
assessments
under
Part
I
of
the
Income
Tax
Act
for
the
1968
and
1969
taxation
years.
The
legislative
provisions
involved
and
the
facts
giving
rise
to
the
controversy
appear
from
a
reading
of
the
reasons
of
the
learned
trial
judge
and
I
propose
to
mention
only
what
I
regard
as
relevant
to
the
view
that
I
take
of
the
merits
of
the
appeal
to
this
Court
on
the
assumption
that
one
has
in
mind
what
appears
in
the
reasons
of
that
learned
judge.
As
it
seems
to
me,
it
is
clear
(1)
that
the
appellant
is
not
entitled
to
the
section
83A
deductions
in
issue
unless
its
principal
business
in
the
1968
and
1969
taxation
years
was
(a)
production,
refining
or
marketing
of
petroleum,
petroleum
products
or
natural
gas,
or
exploring
or
drilling
for
petroleum
or
natural
gas
(hereinafter
referred
to
as
a
“gas
business”),
or
(b)
mining
or
exploring
for
minerals
(hereinafter
referred
to
as
a
“mining
business”);
and
(2)
assuming
that
the
appellant
was
otherwise
entitled
to
such
deductions,
on
the
findings
of
fact
of
the
Trial
Division
(a)
that
the
appellant’s
business
in
1964
was
a
“gas
business”,
and
(b)
that
the
“well”
sold
by
the
appellant
in
1964
was
“all
or
substantially
all
the
property”
used
by
it
in
carrying
on
that
business,
and
assuming
that
such
findings
are
upheld,
that
the
appellant
had,
by
virtue
of
the
sale
of
that
“well”
become
disentitled
to
make
such
deductions,
by
virtue
of
the
concluding
words
of
subsection
83A(8a).
On
the
pleadings
on
which
the
matter
went
to
trial,
it
would
seem
that
both
these
branches
of
the
relevant
facts
were
in
issue.
With
reference
to
the
principal
business
of
the
appellant,
see
paragraph
A(2)
of
the
notice
of
appeal
and
paragraph
A(1)(c)
of
the
amended
reply.
With
reference
to
subsection
83A(8a),
see
section
3(b)
of
the
amended
reply.
By
his
opening
address
at
the
trial,
counsel
for
the
appellant
said
that
the
dispute
was,
essentially,
“whether
or
not
that
single
transaction
in
April,
1964,
amounted
to
a
sale
of
all
or
substantially
all
of
the
assets,
in
which
case
we
admit
that
by
the
operation
of
subsection
8(a)
the
drilling
and
exploration
expenses
which
we
have
sought
to
deduct
.
.
.
flowed
with
the
property”
and
he
further
said:
“Our
position
.
.
.
is
that
was
not
a
sale
of
all
or
substantially
all
of
the
assets
of
the
company
used
by
it
in
carrying
on
its
business
of
petroleum
and
natural
gas
and
mining,
but
therefore
it
continued
to
have
the
right
to
deduct
those
drilling
and
exploration
expenses
in
future
years
when
sufficient
income
was
generated
to
justify
the
use
of
those
credits”
and,
having
said
that,
he
said
“Now
that’s
the
dispute
in
a
nutshell
.
.
.”.
.
In
effect,
as
I
understand
it,
counsel
for
the
appellant,
with
the
acquiescence
of
counsel
for
the
respondent,
drew
the
lines
of
battle
on
the
basis
that
what
had
to
be
decided
was
(a)
the
correctness
of
his
contention
that
the
principal
business
of
the
appellant
in
1964
was
not
a
“gas
business”
but
was
a
combination
of
a
“gas
business”
and
a
“mining
business”;
and
(b)
the
correctness
of
his
contention
that
the
sale
of
the
‘‘well”
was
not
a
sale
of
all
or
substantially
all
of
the
assets
used
by
the
appellant
in
carrying
on
such
business.
No
mention
was
made
in
opening
of
the
other
fact
essential
to
the
appellant’s
success,
which
was
put
in
issue
by
the
pleadings,
viz:
that,
during
the
1968
and
1969
taxation
years,
the
appellant’s
principal
business
was
either
a
“gas
business”
or
“a
mining
business”.,
The
learned
trial
judge
rejected
the
appellant’s
contention
as
to
the
appellant’s
principal
business
in
1964
and
held
that
its
principal
business
in
that
year
was
a
“gas
business”.
I
am
of
opinion
that
there
was
evidence
on
which
he
could
so
find
and
that
it
cannot
be
said
that
such
finding
was
clearly
wrong.
In
reaching
that
conclusion,
I
have
carefully
considered
the
appellant’s
contention
in
this
Court
that
the
learned
trial
judge
failed
to
give
effect:
to
a
legal
principle
established
by
MNR
v
Consolidated
Mogul
Mines
Limited,
[1969]
SCR
54;
[1968]
CTC
429;
68
DTC
5284.
As
I
understand
that
decision,
it
establishes
that
a
person
may
carry
on
a
‘‘mining
business”
by
becoming,
in
effect,
a
partner
in
the
:
‘mining
business”
of
each
of
several
companies
in
each
of
which
it
has
a
substantial
shareholding
and
with
which
it
has
an
arrangement
or
contract
under
which
it,
to
a
large
extent,
controls
the
carrying
on
of
the
other
company’s
mining
activities.
Whether
or
not
a
person
is
carrying
on
such
a
“mining
business”
must
be
a
question
to
be
determined
on
the
facts
of
each
case
and,
in
my
view,
no
facts
have
been
established
in
this
case
to
show
that
the
appellant
was
carrying
on
such
a
business
in
1964.
The
Mogul
case
does
not,
in
my
view,
have
the
effect
of
making
it
follow
as
a
matter
of
law
that
a
parent
company
is
a
company
carrying
on
a
“mining
business”
by
reason
only
of
the
fact
that
its
subsidiary
carries
on
a
“mining
business”,
the
fact
that
the
directors
of
the
two
companies
are
substantially
the
same,
and
rather
vague
indications
of
possible,
minor
uncoordinated
forays
into
mining
exploration
such
as
is
found
on
the
record
of
this
case.
Having
decided
that
the
appellant
was,
in
1964,
carrying
on
a
“gas
business”,
the
learned
trial
judge,
after
a
careful
review
of
the
evidence,
held
that
the
sale
of
the
“well”
in
1964
was
a
sale
of
“substantially
all
the
property’’
used
by
the
appellant
in
that
business.
In
my
view,
he
was
not
only
not
clearly
wrong
in
so
holding
but,
on
the
facts
as
revealed
by
the
record,
he
was
clearly
right.
In
this
Court,
as
I
understood
counsel,
it
was
argued
that
the
relevant
portion
of
subsection
83A(8a)
must
be
construed
as
not
applying
to
a
sale
of
a
single
producing
property
(even
though
it
was
substantially
all
the
assets
used
in
the
activities
of
the
business)
when
the
sale
did
not
include
corporate
books
and
records
that
would
enable
the
purchaser
to
take
advantage
of
the
section
83A
deductions
to
which
it
would
become
entitled
by
virtue
of
subsection
83A(8a)
if
that
provision
did
apply.
In
my
view,
the
relevant
words
of
the
provision
are
not
open
to
any
such
restrictive
interpretation.
I
am,
therefore,
of
opinion
that
the
appeal
should
be
dismissed
with
costs.
I
should,
moreover,
say
that,
in
my
view,
even
if
the
appellant
had
succeeded
in
escaping
from
the
provisions
of
subsection
83A(8a),
the
question
would
still
have
remained
as
to
whether
the
appellant
was
entitled
to
take
advantage
of
subsections
83A(3)
and
(3b),
in
respect
of
the
1968
and
1969
taxation
years,
having
regard
to
the
necessity
of
establishing
that,
in
those
years,
its
principal
business
was
either
a
“gas
business”
or
a
“mining
business”.
Even
if
there
were
admissions
at
trial
on
this
question
(which
is
not
clear
to
me),
having
regard
to
the
evidence,
it
would
seem
that
the
sole
profit-making
operation
of
the
appellant
in
those
years
was
“contract
drilling”,
which,
prima
facie,
is
neither
a
“gas
business”
nor
a
“mining
business”.*
However,
as
this
fact
does
not
appear
to
have
been.
considered
as
being
in
issue
at
trial,
if
it
had
become
relevant,
I
would
have
been
inclined
to
refer
the
assessments
back
to
the
respondent
for
reconsideration
having
regard
only
to
this
aspect
of
the
matter.
In
this
connection,
I
must
express
my
reservation
with
respect
to
any
suggestion
that
subsection
(3)
or
(3b)
would
apply
where
the
“principal
business”
at
the
relevant
time
was
a
combination
of
a
“gas
business”
and
a
“mining
business”
and
was
neither
a
“gas
business”
nor
a
“mining
business”.
