Mahoney,
J:—The
sole
issue
remaining,
after
settlement
and
abandonment
of
other
matters,
is
whether
an
amount
to
provide
Atomic
Energy
of
Canada
Limited,
hereafter
“AECL”,
with
“know-how”
and
a
non-exclusive
licence
under
patents
and
patent
applications
relative
to
the
design,
con-
struction
and
operation
of
a
heavy
water
plant
and
the
processes
involved
in
producing
heavy
water
was
a
capital
or
income
receipt.
The
defendant’s
case
is
based
entirely
on
the
judgment
of
the
Federal
Court
of
Appeal
in
Canadian
Industries
Limited
v
The
Queen,
[1980]
2
FC
463;
[1980]
CTC
222;
80
DTC
6163,
hereafter
CIL.
The
plaintiff
distinguishes
this
case
on
its
facts
from
CIL.
The
plaintiff
is
a
manufacturing
company
serving
primarily
the
electrical
utility,
industrial,
commercial
and
consumer
markets.
Beginning
around
1952,
it
became
actively
involved
in
engineering
and
manufacturing
components
for
the
Candu
nuclear
reactor.
As
far
as
the
evidence
extends
the
generation
of
electricity
by
nuclear
reactors
involves
two
alternative
combinations
of
essential
material:
either
enriched
uranium
with
ordinary
water
or
natural
uranium
with
heavy
water.
Heavy
water,
deuterium
oxide
(D,0),
is
a
naturally
occurring
substance.
It
is
found
in
“ordinary”
water
in
a
proportion
of
about
one
part
in
7000.
It
occurs
in
a
higher
proportion
in
salt
water
than
in
fresh
water.
Heavy
water
is
not
manufactured;
it
is
separated
from
the
ordinary
water.
That
is
what
a
heavy
water
plant
does.
The
Candu
reactor
uses
natural
uranium
and
heavy
water;
its
economic
viability
depends
upon
the
availability
of
substantial
quantities
of
cheap
heavy
water.
“Substantial”
and
“cheap”
are,
of
course,
relative
terms.
Atomic
energy
in
Canada
is
entirely
subject,
in
all
its
aspects,
to
the
control
and
supervision
of
federal
authorities
under
the
Atomic
Energy
Control
Act,
RSC
1970,
c
A-19.
Canada
has
elected
to
base
its
nuclear
energy
development
exclusively
on
the
Candu
reactor.
Heavy
water
is
a
prescribed
substance
under
the
Act.
AECL
is
incorporated
under
authority
of
the
Act
and
exercises
and
performs
powers
conferred
by
it.
For
all
material
purposes,
the
production,
possession
and
marketing
of
heavy
water
have
been
fully
regulated
by
AECL
and
the
Atomic
Energy
Control
Board,
hereafter
the
“Board”,
at
all
times.
Under
contract
with
AECL,
the
plaintiff
built
a
prototype
nuclear
power
plant
at
Rolphton,
Ontario,
which
became
operational
early
in
the
19603.
It
was
successful.
The
plaintiff
developed
experience
and
an
organization
and
expected
to
be
asked
to
build
additional
power
plants
but
it
was
disappointed.
The
decision
to
build
commercial
plants
was
taken
by
Ontario
Hydro.
It
decided
that
there
was
room
for
only
one
builder
in
the
Ontario
market
and,
being
unwilling
to
tie
itself
to
a
single
contractor,
decided
to
build
the
plants
itself
under
licence
from
AECL.
Since
Rolphton,
no
nuclear
power
plants
have
been
built
by
the
private
sector.
AECL
and
Ontario
Hydro
have
cooperated
closely
in
the
commercial
development
of
the
Candu
program
in
Canada.
At
times
material
to
this
action,
the
president
of
Ontario
Hydro
was
a
director
of
AECL.
The
heavy
water
for
the
Rolphton
plant
was
purchased
from
a
plant
at
Savannah
River,
South
Carolina,
the
only
available
source,
which
could
not
supply
the
quantities
needed
beyond
the
pilot
plant
stage.
The
decision
of
AECL
and
Ontario
Hydro
to
proceed
with
commercial
nuclear
power
plants
implied
a
decision
to
build
heavy
water
plants.
AECL
called
tenders;
the
plaintiff
did
not
bid
and
a
contract
was
entered
into
with
Deuterium
Canada
Ltd
to
build
a
200
ton
per
year
plant,
utilizing
salt
water,
at
Glace
Bay,
NS.
It
soon
appeared
that
this
capacity
would
be
inadequate
and
the
plaintiff
was
approached
and
agreed
to
build
a
400
ton
per
year
plant,
utilizing
fresh
water,
at
Port
Hawkesbury,
NS.
The
proposed
capacity
of
the
Glace
Bay
plant
was,
at
the
same
time,
doubled.
The
contract
entered
into
in
early
1966
with
AECL
obliged
the
plaintiff
to
build
the
plant,
own
and
operate
it,
and
to
sell
the
production
to
AECL
on
a
long
term,
firm
price
contract.
Having
been
disappointed
in
its
plans
for
building
nuclear
power
plants,
the
plaintiff
obtained
a
right
of
first
refusal
from
AECL
to
build
future
heavy
water
plants.
The
plaintiff
contacted
The
Lummus
Company,
which
had
built
and
was
operating
the
Savannah
River
plant
for
the
US
Atomic
Energy
Commission.
It
and
its
Canadian
subsidiary
are
collectively
hereafter
called
“Lummus”.
Lummus
contracted
to
participate
in
the
design,
engineering
and
construction
of
the
Port
Hawkesbury
plant.
The
agreement
provided
that
all
technical
data
generated
would
become
the
plaintiff’s
property
and
for
the
joint
promotion
oif
the
use
of
the
processes,
know-how
and
technical
information
developed
and
for
the
licensing
of
the
same
to
third
parties.
Any
such
licence
was
to
carry
with
it
a
non-exlusive
licence
under
the
plaintiff’s
pertinent
patents.
While
it
was
hoped
that
any
third
party
would
avail
itself
of
the
services
of
both
the
plaintiff
and
Lummus,
the
agreement
contemplated
the
possibility
of
licensing
a
third
party
willing
to
deal
with
only
one
of
them.
No
licences
were,
in
fact,
ever
granted
pursuant
to
this
arrangement;
it
is
relevant
only
as
evidence
of
the
plaintiff’s
intentions
prior
to
the
transaction
in
issue.
By
the
summer
of
1968,
two
crucial
events
had
occurred.
Ontario
Hydro
had
determined
to
further
expand
its
nuclear
power
capacity
and
the
Glace
Bay
heavy
water
plant
was
recognized
as
a
probable
failure.
Substantial
additional
heavy
water
production
was
urgently
needed.
AECL
saw
the
commercial
future
of
the
Candu
program
depending
on
its
supply.
At
first,
Ontario
Hydro
considered
undertaking
construction
of
the
additional
heavy
water
production
in
conjunction
with
its
nuclear
power
plants
but
AECL
decided
to
assume
that
responsibility.
The
additional
heavy
water
production
was,
however,
to
be
physically
located
with
the
nuclear
power
plants
as
their
excess
steam
would
provide
a
power
source
for
the
heavy
water
production
much
cheaper
than
any
available
alternative.
AECL
offered
the
plaintiff
the
opportunity
to
build
and
own
the
new
heavy
water
facilities
as
obliged
under
the
first
refusal.
The
Port
Hawkesbury
plant
was
nearing
completion
but
had
yet
to
be
commissioned.
The
plaintiff’s
investment
at
Port
Hawkesbury
represented
some
52%
of
its
investment
in
fixed
assets
and
an
amount
equal
to
about
a
quarter
of
its
equity.
Having
regard
to
the
investment
required,
it
was
out
of
the
question,
from
a
business
point
of
view,
for
the
plaintiff
to
make
the
additional
commitment
before
it
was
certain
that
the
Port
Hawkesbury
plant
would
work
and
be
profitable.
The
plaintiff
was
not
in
a
position
to
exercise
its
right
of
first
refusal
within
the
necessary
time
frame.
Unknown
to
the
plaintiff,
Lummus
had
been
working
directly
with
Ontario
Hydro
prior
to
the
plaintiff
being
offered
the
opportunity
to
exercise
its
right
of
first
refusal.
While
nothing
turns
on
that,
it
may
explain
why
Lummus
was
left
out
of
the
deal
when
the
plaintiff
sold
the
know-how
to
AECL.
Lummus
apparently
was
going
to
have
the
opportunity
to
cash
in
on
its
know-how
in
any
event.
So
much
for
the
background
to
the
transaction
that
gave
rise
to
the
receipt
in
issue.
The
plaintiff
had
gone
into
the
Port
Hawkesbury
project
with
the
clear
expectation
that
heavy
water
production
would
prove
an
expanding
business
opportunity
to
someone
in
on
the
ground
floor.
An
obvious
avenue
for
realization
of
the
business
opportunity
was
the
licensing
of
the
know-how
generated;
another
obvious
avenue
was
the
construction
and
operation
of
additional
production
facilities
for
its
own
account.
As
to
the
first
avenue,
Lummus
was
obviously
going
to
possess
a
good
deal
of
the
know
how
in
fact
and
it
was
prudent
to
agree
on
a
basis
for
a
joint
exploration
of
it.
The
plaintiff’s
first
opportunity
to
pursue
the
latter
avenue
came
too
soon
and
it
had,
for
compelling
business
reasons,
to
pass
it
up.
Ontario
Hydro
had
been,
was
and
remains
the
plaintiff’s
largest
single
customer.
AECL
was
the
sole
market
for
the
output
of
its
largest
capital
investment
and,
between
them,
AECL
and
the
Board
had
complete
regulatory
authority
over
any
use
which
might
be
made
of
the
inventions
and
know-how.
Ontario
Hydro
and
AECL
wanted
AECL
to
have
use
of
the
inventions
and
know-how.
The
evidence
is
that
the
licensing
agreement
permitted
AECL
to
bring
its
heavy
water
plant
to
production
two
years
earlier
than
would
otherwise
have
been
possible.
The
plaintiff
felt,
and
I
am
entirely
satisfied
on
the
evidence,
correctly
so,
that
it
had
no
real
choice
but
to
sell
it.
The
plaintiff
also
felt,
and
events
have
proved
it
correct
to
date,
that
the
decision
of
AECL
to
undertake
production
of
heavy
water
for
its
own
account
marked
the
end
of
that
business
opportunity
in
Canada,
just
as
the
decision
of
Ontario
Hydro
to
build
its
own
nuclear
power
plants
had
marked
the
end
of
private
sector
opportunities
in
that
area.
The
plaintiff’s
traditional
market
for
equipment
remained
but
its
opportunity
to
build,
own
and
operate
additional
plants
in
Canada
was
foreclosed.
Some
years
later,
the
Port
Hawkesbury
plant
was
sold
to
AECL
and
the
payment
in
issue
was
taken
into
account
in
determining
the
price.
The
Glace
Bay
plant
was
also
bought
by
AECL
and
completely
rebuilt
to
utilize
fresh
water.
The
original
plant
never
produced.
Today,
AECL
is
the
sole
producer
of
heavy
water
in
Canada.
The
plaintiff
does
license
its
patents
to
third
parties
on
occasion.
In
the
area
of
household
appliances,
there
is
a
great
deal
of
cross
licensing
between
manufacturers.
This
is
not
an
important
revenue
consideration
but,
rather,
it
is
an
important
measure
to
avoid
constantly
suing
and
being
sued.
The
plaintiff
did,
prior
to
the
transaction
in
issue,
at
the
request
of
AECL,
sell
certain
of
its
reactor
know-how
to
French
and
Italian
public
atomic
energy
authorities.
It
was
reactor,
not
heavy
water,
know-how;
the
consideration
was
nominal
in
the
context
of
the
plaintiff’s
overall
sales
revenue,
a
total
of
$159,500
for
the
know-how.
The
plaintiff’s
revenues
from
fees
for
licensing
patents
has,
over
the
past
ten
years,
run
between
$500,000
and
$800,000
per
annum,
about
0.01%
of
its
revenue.
About
half
of
that
revenue
derived
from
one
license
involving
a
patent
for
wire
wrapping
insulation.
By
agreement
dated
as
of
November
18,
1968,
the
plaintiff
agreed
to
provide
AECL
with
drawings
and
specifications,
technical
information
as
to
the
procurement
and
cost
of
materials
and
equipment,
and
advice
and
information
with
respect
to
commissioning
and
operating
expenses
of
the
Port
Hawkesbury
plant,
herein
the
“know-how”,
and
also
granted
AECL
a
non-
exclusve,
worldwide,
licence
respecting
the
inventions
subject
of
certain
Canadian
patent
applications
pending
and
proposed,
in
consideration
of
the
lump
sum
of
$1,500,000,
unrelated
to
the
extent
of
use,
payable
in
prescribed
instalments.
$750,000
was
received
in
the
plaintiff’s
1968
taxation
year
and
is
subject
of
this
action.
$250,000
was
received
in
its
1971
taxation
year
and
is*
subject
of
action
No
T-3094-76,
which
was
tried
on
common
evidence
with
this
action.
The
balance
was
received
in
the
plaintiff’s
1974
taxation
year
and
is
subject
of
an
assessment
that
remains
open
pending
disposition
of
the
present
actions.
It
is
entirely
appropriate
to
characterize
the
know-how
in
issue
here
as
“a
capital
asset
analogous
to
patent
rights”.
In
that
circumstance,
it
is
of
no
import
that
the
licensing
agreement
did
not
allocate
the
consideration
as
between
know-how
and
licences
under
the
patents
and
that
there
is
no
evidence
upon
which
such
an
allocation
could
be
made.
CIL
analysed
exhaustively
the
British
judgments
on
this
issue
including
those
to
which
the
plaintiff
made
particular
reference:
British
Dyestuffs
v
CIR,
12
TC
586;
Handley
Page
v
Butterworth,
19
TC
328;
Evans
Medical
Supplies
v
Moriarty,
37
TC

Jeffrey
v
Rolls-Royce,
Ltd,
40
TC
443;
and
Wolf
Electric
Tools
Ltd
v
Wilson,
45
TC
326.
The
analysis
confirms
the
fundamental
validity
of
the
principle
enunciated
by
Lord
Pearce
in
BP
Australia
Ltd
v
Commissioner
of
Taxation,
[1966]
AC
224
at
264ff:
The
solution
to
the
problem
is
not
to
be
found
by
any
rigid
test
or
description.
It
has
to
be
derived
from
many
aspects
of
the
whole
set
of
circumstances
some
of
which
may
point
in
one
direction,
some
in
the
other.
One
consideration
may
point
so
Clearly
that
it
dominates
other
and
vaguer
indications
in
the
contrary
direction.
It
is
a
commonsense
appreciation
of
all
the
guiding
features
which
must
provide
the
ultimate
answer.
Although
the
categories
of
capital
and
income
expenditure
are
distinct
and
easily
ascertainable
in
obvious
cases
that
lie
far
from
the
boundary,
the
line
of
distinction
is
often
hard
to
draw
in
border
line
cases;
and
conflicting
considerations
may
produce
a
situation
where
the
answer
turns
on
questions
of
emphasis
and
degree.
.
..
As
each
new
case
comes
to
be
argued
felicitous
phrases
from
earlier
judgments
are
used
in
argument
by
one
side
and
the
other.
But
those
phrases
are
not
the
deciding
factor,
nor
are
they
of
unlimited
application.
They
merely
crystallise
particular
factors
which
may
incline
the
scale
in
a
particular
case
after
a
balance
of
all
the
considerations
has
been
taken.
That
principle
was
cited
with
approval
in
MNR
v
Algoma
Central
Railway,
[1968]
SCR
447;
[1968]
CTC
161;
68
DTC
5096.
The
essential
question
in
CIL
was
identified,
at
page
486,
as
being:
Does
the
evidence
show
that
CIL
lost
its
business
for
military
TNT
with
the
United
States
Government
as
a
direct
and
necessary
result
of
entering
into
the
License
Agreement?
The
essential
question
here
cannot
be
so
stated
because,
in
this
case,
the
effect
of
the
decisions
by
AECL
and
Ontario
Hydro
to
demand,
when
they
did,
additional
heavy
water
production
was
to
eliminate,
de
facto,
the
plaintiff’s
opportunity
to
make
further
use,
in
Canada,
of
the
inventions
and
know-how
generated
in
the
design,
construction
and
commissioning
of
the
Port
Hawkesbury
plant.
Those
decision
antedated
the
offer
to
buy
the
knowhow
and
licences.
The
plaintiff
had
not
undertaken
the
Port
Hawkesbury
plant
with
a
view
to
building
and
operating
only
it.
It
had
seen
a
golden
opportunity
to
build
and
operate
other
plants
if
it
built
the
first
one
and
it
saw
that
opportunity
disappear
with
the
Ontario
Hydro
and
AECL
decisions.
The
essential
question
here
is
not
whether
the
plaintiff
lost
a
particular
business
as
a
result
of
entering
into
the
licensing
agreement;
it
lost
none
of
the
business
attaching
directly
to
the
Port
Hawkesbury
plant
and
it
had
already
lost
the
opportunity
to
engage
in
that
business
elsewhere
in
Canada.
The
facts
peculiar
to
this
case
distinguish
it
from
CIL
and
from
the
other
authorities
considered
in
C/L.
While
the
plaintiff
does
grant
licences
of
its
patents
in
the
ordinary
course
of
its
business
and
does,
on
occasion,
sell
its
know-how,
this
transaction
was
not
in
the
ordinary
course
of
its
business.
Neither
was
it
an
adventure
in
the
nature
of
trade.
It
was
not
undertaken
with
a
view
to
realizing
a
profit.
Rather
it
was
essentially
a
salvage
operation,
a
realization
of
a
capital
asset
which,
in
the
circumstances,
was
of
considerable
immediate
value
to
AECL
and
of
no
apparent
future
value
to
the
plaintiff
in
the
Canadian
market.
The
