Cattanach,
J:—This
is
an
appeal
from
an
assessment
to
income
tax
by
the
Minister
for
the
plaintiff’s
taxation
year
ending
October
31,
1968.
The
issue
in
this
appeal
and
the
rival
contentions
with
respect
to
the
issue
resolved
themselves
into
a
very
narrow
compass.
The
issue
is
whether
the
principal
business
of
the
plaintiff
in
its
1968
taxation
year
was
production,
refining
or
marketing
of
petroleum,
petroleum
products
or
natural
gas
or
exploring
or
drilling
for
petroleum
or
natural
gas
within
the
meaning
of
paragraph
83A(3b)(a)
of
the
Income
Tax
Act.
if
that
is
the
case
then
the
plaintiff,
in
accordance
with
formulae
outlined
in
subsection
83A(3b),
may
deduct
in
computing
its
income
under
Part
I
of
the
Act,
in
effect
the
aggregate
of
its
drilling
and
exploration
expenses
incurred
in
the
year
to
the
extent
that
those
expenses
were
not
previously
deducted.
The
amount
of
those
expenses
total
$955,000.
Expenses
in
the
amount
of
$55,000
were
incurred
by
the
plaintiff
for
exploring
and
drilling
for
oil
in
October
1968
and
the
plaintiff
acquired
oil
and
gas
exploration
rights
at
a
cost
of
$900,000
also
in
October
1968.
it
is
admitted
by
the
Minister
that
the
expenditure
of
$900,000
by
the
plaintiff
was
for
the
acquisition
of
exploration
and
drilling
rights
within
the
meaning
of
subsection
83A(5a)
and
as
such
are
deemed
by
subsection
83A(5a)
to
be
a
drilling
and
exploration
expense
for
the
purposes
of
subsection
83A(3b).
The
pertinent
portion
of
subsection
83A(3b)
reads
as
follows:
83A.
(3b)
A
corporation
whose
principal
business
Is
(a)
production,
refining,
or
marketing
of
petroleum,
petroleum
products
or
natural
gas,
or
exploring
or
drilling
for
petroleum
or
natural
gas,
may
deduct,
in
computing
its
income
under
this
Part
for
a
taxation
year,
the
lesser
of.
.
.
The
formula
for
determining
the
amounts
deductible
is
then
outlined
in
paragraphs
(f)
and
(g)
of
subsection
(3b)
of
section
83A
but
there
is
no
dispute
between
the
parties
as
to
the
deductibility
of
a
total
amount
of
$955,000
provided
the
plaintiff
qualifies
as
a
corporation
whose
principal
business
as
outlined
in
paragraph
(a)
of
subsection
(3b)
of
section
83A
which
is
reproduced
above.
The
contention
of
the
plaintiff
is
that
the
principal
business
of
the
plaintiff
was,
in
the
taxation
year
in
question,
as
described
in
paragraph
(a)
whereas
the
Minister
contends
that
its
principal
business
was
otherwise.
Therein
lies
the
dispute
between
the
parties.
The
plaintiff
was
incorporated
pursuant
to
the
laws
of
the
province
of
Ontario
by
letters
patent
dated
May
18,
1966
under
the
name
of
McDougall
Walbridge
Aldinger
(Ontario)
Limited
for
the
purpose
of
carrying
on
the
business
of
builders
and
general
contractors.
The
company
was
formed
by
the
Walbridge,
Aldinger
Company
of
Detroit,
Michigan
and
by
W
A
McDougall
Ltd
of
London,
Ontario
each
of
whom
held
50%
of
the
issued
shares
of
the
capital
stock
of
the
plaintiff.
in
effect
the
plaintiff
was
a
combination
of
the
resources
of
the
Detroit-based
and
London-based
companies.
The
Detroit-based
company
had
done
work
for
the
Ford
Motor
Company
and
the
London-based
company
had
construction
equipment
in
that
area.
The
plaintiff
company
so
formed
was
the
successful
bidder
for
the
construction
of
an
automobile
assembly
plant
for
Ford
Motor
Company
of
Canada
Limited
(hereinafter
referred
to
as
Ford)
at
St
Thomas,
Ontario.
The
original
contract
with
Ford
was
for
the
foundation
work,
footings,
caissons
and
concrete
work.
If
I
recall
the
evidence
correctly
the
plaintiff’s
bid
was
in
the
neighbourhood
of
$5,000,000.
However
over
a
period
of
14
months
from
the
beginning
of
construction
in
1966
the
contract
went
through
some
338
change
orders
or
amendments
so
that
the
plaintiff
was
continuously
engaged
in
the
completion
of
the
project
which
was
the
construction
of
the
Ford
assembly
plant
and
turning
it
over
to
Ford
in
an
operable
condition.
Again
it
is
my
recollection
that
the
total
cost
of
the
project
was
approximately
$27,850,000.
The
contract
was
referred
to
as
a
turn-key
contract.
In
October
and
November
1967
there
were
about
200
employees
of
the
plaintiff
all
of
whom
were
iron
workers
doing
the
final
work
of
completing
the
conveyor
assembly
in
the
plant.
Ford
went
into
production
before
Christmas
1967.
Mr
McDougall
bought
an
automobile
which
came
off
the
assembly
line
in
December
1967.
There
were
no
employees
of
the
plaintiff
working
on
the
site
as
at
February
1,
1968.
There
were
no
sub-trades
on
the
site
except
about
20
men
doing
the
final
landscaping.
The
job
superintendent
left
the
job
in
November
1967
and
returned
to
the
employ
of
W
A
McDougall
Ltd
on
projects
underway
in
Eastern
Canada.
Mr
McDougall
testified
that
the
work
was
completed
on
February
1,
1968
subject
to
cleaning-up
exercises
in
which
he
estimated
that
some
200
man-days
were
expended
by
employees
of
the
plaintiff
and
400
man-days
by
employees
of
the
sub-trades.
It
is
the
contention
of
the
plaintiff
that
the
project
was
completed
in
February
1968.
On
the
other
hand
counsel
for
the
Minister
contended
that
the
construction
business
of
the
plaintiff
continued
throughout
the
plaintiff’s
financial
year
ending
October
31,
1968
and
into
the
next
ensuing
financial
year.
He
based
that
contention
by
analogy
to
remarks
made
in
Sorbara
v
MNR,
[1965]
1
Ex
CR
191;
[1964]
CTC
536;
64
DTC
5325,
where
it
was
said
at
page
199
[543,
5330]:
_.
.
In
my
view,
the
business
of
acquiring
land
for
disposition
at
a
profit
includes
all
operations
essential
to
the
successful
completion
of
the
project,
including
not
only
sale,
or
other
disposition,
but
collection
of
the
proceeds
of
disposition.
He
then
pointed
out
that
there
were
approximately
20
work-order
amendments,
the
invoices
for
which
were
dated
from
April
1968
to
August
1968.
Mr
McDougall
explained
that
the
work
had
been
done
and
the
officers
of
the
plaintiff
were
negotiating
with
Ford
as
to
the
amounts
payable
under
the
work-order
amendments.
When
this
was
settled
the
invoices
issued.
The
officers
of
the
plaintiff
had
a
meeting
each
month
with
Ford
to
negotiate
the
amounts
payable.
The
job
superintendent
had
been
paid
a
bonus
of
$67,000.
He
left
the
job
in
the
fall
of
1967.
In
the
July
previous
he
had
been
paid
$15,000.
The
balance
of
$52,000
was
paid
to
him
August
1969
which
was
well
into
the
next
fiscal
period
of
the
plaintiff.
The
financial
statement
of
the
plaintiff
for
the
year
ending
October
31,
1968
disclosed
as
an
asset
an
amount
of
$378,000
due
from
Ford.
The
final
invoice
to
Ford
in
the
amount
of
$318,000
was
sent
on
October
23,
1968,
seven
days
before
the
fiscal
year
end
and
was
paid
in
November
1968.
The
explanation
of
the
discrepancy
between
the
amounts
of
$378,000
and
$318,000
was
that
the
negotiations
with
Ford
resulted
in
the
lesser
amount.
The
plaintiff
was
originally
incorporated
to
construct
one
project,
namely,
the
Ford
motor
assembly
plant.
Therefore
the
construction
business
of
the
plaintiff
would
come
to
an
end
of
its
own
weight
on
the
completion
of
that
project.
The
evidence
is
that
the
plant
was
completed
before
March
1,
1968
and
all
that
remained
to
be
done
was
to
negotiate
with
Ford
and
collect
the
amounts
determined
to
be
payable.
On
completion
of
the
Ford
plant
the
Walbridge
Aldinger
Company
of
Detroit
wanted
out
of
the
plaintiff
company.
This
separation
was
arranged.
The
profits
resulting
from
the
construction
of
the
Ford
plant
were
divided.
W
A
McDougall
Ltd
became
the
sole
beneficial
shareholder
of
the
plaintiff
and
there
remained
in
the
plaintiff
liquid
assets
in
the
approximate
amount
of
$1,273,000
being
the
appropriate
share
of
the
profits
from
the
construction
business.
The
plaintiff
therefore
sought
other
forms
of
business
activity.
After
investigation
it
was
decided
to
enter
the
oil
and
gas
business.
By
supplementary
letters
patent
dated
October
16,
1968
the
objects
authorizing
the
plaintiff
to
engage
in
the
construction
business
were
deleted
and
objects
authorizing
it
to
engage
in
an
oil
and
gas
business
were
substituted
therefor.
The
plaintiff
obtained
an
extra-provincial
licence
from
the
Province
of
Alberta
in
October
1968
authorizing
it
to
carry
on
business
in
that
Province.
By
supplementary
letters
patent
dated
April
30,
1969
the
corporate
name
of
the
plaintiff
was
changed
from
McDougall
Walbridge
Aldinger
(Ontario)
Limited
to
MWA
Gas
and
Oil
Limited
which
name
appears
in
the
style
of
cause.
As
previously
recited
the
plaintiff
incurred
oil
and
gas
drilling
and
exploration
expenses
in
the
amount
of
$55,000
and
acquired
oil
and
gas
exploration
and
drilling
rights
at
a
cost
of
$900,000
both
of
which
amounts
were
paid
by
the
plaintiff
by
cheque
in
October
1968.
In
its
1968
taxation
year
the
plaintiff
received
revenue
from
its
oil
and
gas
business
in
the
amount
of
$8,124
and
in
its
1969,
1970
and
1971
financial
years
it
received
revenue
in
the
approximate
amount
of
$350,000
in
each
year.
From
these
figures
I
observe
that
the
plaintiff
recouped
its
expenses
in
three
years.
The
contention
of
the
Minister,
as
I
understood
it,
is
that
the
language
of
subsection
83A(3b)
reading,
“A
corporation
whose
principal
business
is”
of
necessity
means
that
a
corporation
can
have
only
one
principal
business
in
a
taxation
year
and
that
no
particular
period
of
time
within
the
taxation
year
is
of
more
paramount
importance
than
any
other
period.
Assuming
the
Minister’s
contention
to
be
correct,
it
follows
that
I
must
decide
which
of
the
two
businesses,
namely,
the
construction
business
and
the
business
of
exploring
and
drilling
for
gas
and
oil
carried
on
by
the
plaintiff
in
its
1968
taxation
year,
was
its
principal
business.
In
contradistinction
the
position
taken
by
the
plaintiff
is
that
until
March
1,
1968
the
plaintiff
was
exclusively
in
the
business
of
construction.
Since
that
was
its
sole
business
at
that
time
it
was
its
principal
business.
However
it
was
the
plaintiff’s
contention
that
the
active
construction
business
ended
on
March
1,
1968
on
the
completion
of
the
project
and
from
that
time
forward
the
plaintiff
was
dormant
until
October
1968
when
it
actively
embarked
on
an
oil
and
gas
business.
The
crux
of
the
argument
on
behalf
of
the
plaintiff,
as
I
understood
it,
was
that
a
corporation
can
have
two
principal
businesses
within
a
taxation
year
provided
there
is
an
hiatus
between
the
conclusion
of
one
business
and
the
inception
of
another.
In
American
Metal
Company
of
Canada,
Ltd
v
MNR,
[1952]
CTC
302:
52
DTC
1180,
Cameron,
J
had
occasion
to
consider
which
of
two
businesses
being
carried
on
concurrently
was
a
corporation’s
“chief”
business.
The
pertinent
words
of
the
section
then
in
effect
were
‘‘a
corporation
whose
chief
business
is
that
of
mining
or
exploring
for
minerals
is
entitled
to
deduct
from
income”
expenses
incurred
for
prospecting,
exploration
and
by
development
in
the
taxation
year.
He
said
at
page
306
[1182]:
“Chief
business”
Is
not
defined
in
eIther
of
the
Acts
and
the
phrase,
so
far
as
I
am
aware,
has
not
been
the
subject
of
judicial
interpretation.
In
my
view
it
is
a
question
of
fact
to
be
determined
by
an
examination
and
comparison
of
all
the
facts
concerning
each
of
the
various
types
of
business
in
which
the
company
is
engaged.
.
..
In
MNR
v
Consolidated
Mogul
Mines
Limited,
[1968]
CTC
429;
68
DTC
5284,
Spence,
J,
speaking
for
the
Supreme
Court
of
Canada,
quoted
and
approved
the
foregoing
statement
by
Cameron,
J
and
applied
the
test
therein
set
forth.
He
noted
that
the
statute
then
under
consideration
contained
no
definition
of
“principal
business”
although
“business”
is
defined
in
paragraph
139(1)(e)
in
a
manner
not
relevant
to
the
question
under
review.
The
same
circumstance
is
applicable
in
the
present
instance.
There
is
no
distinction
consequent
upon
the
use
of
the
adjective
“principal”
in
place
of
the
adjective
“chief”.
In
their
respective
contexts
the
words
are
synonymous.
I
therefore
revert
to
the
contention
of
the
Minister,
without
purporting
to
decide
the
matter,
that
a
corporation
can
have
only
one
principal
business
in
a
taxation
year.
As
I
have
said
before
it
is
implicit
in
the
submission
that
a
corporation
can
have
only
one
principal
business
that
the
question
to
be
decided,
as
one
of
fact,
is
which
of
the
plaintiff’s
businesses
in
its
taxation
year
was
its
principal
business.
In
this
case
the
only
business
of
the
plaintiff
following
its
incorporation
in
1966
was
the
construction
of
the
Ford
assembly
plant
at
St
Thomas,
Ontario.
The
plaintiff
was
incorporated
for
that
project
only.
There
is
ample
justification
for
that
conclusion.
The
Detroit-based
company
had
a
long
association
with
and
was
favourably
known
to
Ford.
The
London-based
company
had
experience
in
the
construction
business
in
that
area.
The
Detroit-based
company
became
a
shareholder
in
the
plaintiff
for
the
construction
of
this
particular
plant
only.
This
is
borne
out
by
the
subsequent
event
that
upon
the
completion
of
the
plant
it
severed
its
connection
with
the
plaintiff.
The
plant,
in
an
operable
state,
was
completed
in
December
1967.
Ford
motor
cars
came
off
the
assembly
line
in
that
month.
All
that
remained
to
be
done
was
in
the
nature
of
a
cleaning-up
exercise,
the
landscaping
and
the
installation
of
external
iron
railings.
This
work
was
completed
by
March
1,
1968.
As
of
that
date
the
plaintiff
had
no
more
employees
on
the
job,
its
job
superintendent
had
left
the
site
and
the
plaintiff's
employ
in
November
1967.
All
employees
of
the
sub-trades
had
left
the
site
prior
to
that
date.
In
short
the
physical
construction
of
the
plant
was
completed
as
ot
that
date.
All
that
remained
to
be
done
was
for
the
officers
of
the
plaintiff
to
settle
with
Ford
the
compensation
for
the
work
done
pursuant
to
change
orders
and
accept
the
payment
of
those
amounts
when
determined.
The
actual
work
covered
thereby
had
been
undertaken
and
completed
by
the
plaintiff
prior
to
March
1,
1968.
I
do
not
accept
the
testimony
of
Mr
McDougall
that
the
plaintiff
then
became
dormant
and
remained
dormant
until
October
1968
when
it
became
engaged
in
exploring
and
drilling
for
oil
and
gas.
The
plaintiff
performed
numerous
corporate
acts
in
the
interval.
However
I
do
accept
as
a
fact
that
the
plaintiff
ceased
to
be
engaged
actively
in
the
construction
business
as
of
that
date.
To
all
intents
and
purposes
the
plaintiff’s
active
engagement
in
the
construction
business
ended
as
of
that
date
never
to
be
revived
again
nor
was
it
the
intention
of
the
plaintiff
from
its
inception
to
engage
in
the
construction
business
on
completion
of
this
particular
Ford
plant.
What
the
plaintiff
did
after
that
date
was
directed
merely
to
winding
up
its
construction
business.
It
is
quite
true
that
the
revenue
that
the
plaintiff
received
in
its
1968
taxation
year
from
the
completed
construction
work
exceeded
the
revenue
from
the
oil
and
gas
business
in
which
the
plaintiff
engaged
in
October
1968
and
so
too
the
profit
from
the
construction
business
received
by
the
plaintiff
in
its
1968
taxation
year
far
exceeded
the
profit
from
the
oil
and
gas
business
in
that
year
which
was
a
negative
quantity.
However,
Mr
Justice
Cameron
said
in
the
American
Metal
case
(supra)
that
the
comparative
income
received
by
a
corporation
from
two
businesses
carried
on
by
it
is
an
important
element
to
be
considered
in
determining
which
is
the
chief
business
but
that
is
not
the
only
matter
to
be
considered
and
is
not
necessarily
the
determining
factor.
On
the
other
hand
the
plaintiff
abandoned
its
construction
business
in
the
1968
taxation
year
and
became
engaged
in
the
oil
and
gas
business
in
that
year.
In
that
year
supplementary
letters
patent
were
obtained
authorizing
the
plaintiff
to
carry
on
an
oil
and
gas
business
to
the
exclusion
of
a
construction
business
and
it
exercised
those
changed
objects
in
1968.
From
that
time
forward
the
sole
business
of
the
plaintiff
was
that
of
exploring
and
drilling
for
oil
and
gas
and
in
its
1969,
1970,
1971
and
1972
financial
years
it
derived
substantial
income
from
that
business.
Because
that
was
the
sole
business
from
October
1968
on
it
follows
as
from
that
date
it
was
the
plaintiff’s
principal
business.
The
plaintiff
did
not
have
employees,
as
distinct
from
officers,
engaged
in
the
oil
and
gas
business.
It
operated
through
the
facilities
of
Voyager
Petroleum
Limited.
Again
in
the
American
Metal
case
(supra)
Cameron,
J
pointed
out
that
the
number
of
employees
in
the
respective
businesses
is
an
element
in
determining
which
of
the
two
businesses
is
the
chief
business
but
that
it
is
not
necessarily
the
determining
factor.
It
was
preordained
from
the
inception
of
the
plaintiff
that
its
construction
business
would
end
on
the
completion
of
the
Ford
project.
That
end
was
readily
foreseeable
in
the
early
part
of
the
plaintiff’s
1968
taxation
year
from
the
beginning
of
that
year.
What
the
plaintiff
was
doing
from
November
1967
to
March
1968
of
its
1968
taxation
year
was
drawing
its
construction
business
to
its
inevitable
end.
In
the
initial
four
months
of
that
financial
year
of
the
plaintiff’s
construction
business
was
on
the
wane
until
its
ultimate
demise
on
March
1,
1968.
There
then
followed
a
period
of
inactivity,
but
for
passive
corporate
acts,
until
the
oil
and
gas
business
was
conceived
and
actively
engaged
in
in
October
1968.
In
the
plaintiff’s
1968
taxation
year
its
construction
business
was
in
its
death
throes
while
the
oil
and
gas
business
was
born
and
in
its
dynamic
infancy
reaching
maturity
in
the
succeeding
year.
In
my
opinion
these
facts
establish
that
while
the
construction
business
had
been
the
plaintiff’s
principal
business
that
business
was
superseded
by
the
oil
and
gas
business
as
the
plaintiff’s
principal
business
in
its
1968
taxation
year.
For
the
foregoing
reasons
I
conclude,
as
a
question
of
fact,
that
the
plaintiff’s
principal
business
was
that
of
exploring
or
drilling
for
petroleum
or
natural
gas,
and
so
falls
precisely
within
the
qualification
for
the
deduction
of
exploring
and
drilling
expenses
incurred
by
it
in
computing
its
income
for
its
1968
taxation
year
in
accordance
with
subsection
83A(3b).
Because
of
the
conclusion
I
have
reached,
it
becomes
unnecessary
for
me
to
decide
between
the
rival
contentions
on
behalf
of
the
parties,
which
were,
on
the
one
hand,
that
subsection
83A(3b)
prescribes
that
a
corporation
can
have
only
one
principal
business
in
a
taxation
year
and,
on
the
other
hand,
that
a
corporation
can
have
two
principal
businesses
in
one
taxation
year,
within
the
meaning
of
subsection
83A(3b),
provided
that
there
is
an
hiatus
between
the
conclusion
of
one
business
and
the
inception
of
another.
The
appeal
is,
therefore,
allowed
with
costs
to
the
plaintiff.
