LeDain,
J:—This
is
an
appeal
from
a
judgment
of
the
Trial
Division
dismissing
an
appeal
from
a
decision
of
the
Tax
Review
Board
which
had
dismissed
an
appeal
from
a
reassessment
in
respect
of
the
1969
taxation
year
of
the
late
Roy
J
Perini
by
which
the
amount
of
$14,031.19
was
included
as
interest
in
the
calculation
of
his
income.
It
is
one
of
three
related
appeals
which
raise
the
same
issue,
the
other
two
being
A-118-78
and
A-119-78,
which
relate
to
reassessments
in
respect
of
the
taxpayer’s
1970
and
1971
taxation
years
by
which
the
amounts
of
$28,431.74
and
$119,262.60
respectively
were
included
as
interest
in
the
calculation
of
his
income.
The
three
appeals
were
heard
together
on
common
evidence
in
the
Trial
Division
and
in
this
Court.
The
reasons
in
this
appeal
will
serve
to
dispose
of
the
issue
in
the
other
two.
The
appeals
have
been
continued
by
the
executor
and
trustee
of
the
late
Mr
Perini.
The
issue
is
whether
the
sum
of
$14,031.19
paid
to
Mr
Perini
under
the
term
of
an
agreement
for
the
sale
of
shares,
in
which
the
payment
in
question
is
referred
to
as
“interest”,
was
an
income
or
capital
receipt.
The
issue
turns
on
the
fact
that
the
principal
amount
upon
which
the
payment
referred
to
as
“interest”
was
to
be
calculated
had
not
been
determined
at
the
date
from
which
the
interest
was
to
run.
The
agreement,
entered
into
as
of
November
14,
1968,
provided
for
the
sale
by
Mr
Perini
of
all
of
the
issued
shares
in
the
capital
stock
of
All
Records
Supply
of
Canada
Ltd
(“ARS”)
to
Columbia
Records
of
Canada
Ltd
(“CRC”)
“at
a
price
determined
pursuant
to
paragraph
1.3”
of
the
agreement,
which
reads
as
follows:
1.3
As
full
payment
for
the
Sale
Shares,
CRC
will
pay
Seller
as
follows:
(i)
At
the
Closing
$660,000
(all
sums
herein
are
expressed
in
Canadian
dollars);
(ii)
Following
receipt
of
an
audited
financial
statement
for
the
year
ended
April
30,
1969
—
a
payment
equal
to
the
lesser
of
(A)
$400,000
and
(B)
the
result
obtained
by
dividing
the
post-tax
net
profits
of
ARS
for
such
year
by
$186,000
and
multiplying
the
result
by
$400,000;
(iii)
Following
receipt
of
an
audited
financial
statement
for
the
year
ended
April
30,
1970
—
a
payment
which
shall
cause
the
total
payments
under
this
clause
(iii)
and
the
preceding
clause
(ii)
to
equal
the
lesser
of
(A)
$800,000
and
(B)
the
result
obtained
by
dividing
the
net
aggregate
of
the
post-tax
net
profits
(after
deducting
losses)
of
ARS,
as
determined
by
said
audited
financial
statement,
for
the
two
fiscal
years
ended
April
30,
1969
and
1970
by
$372,000
and
multiplying
the
result
by
$800,000;
(iv)
Following
receipt
of
an
audited
financial
statement
for
the
year
ended
April
30,
1971
—
a
payment
which
shall
cause
the
total
payments
under
this
clause
(iv)
and
the
preceding
clauses
(ii)
and
(iii)
to
equal
the
lesser
of
(A)
$1,200,000
and
(B)
the
result
obtained
by
dividing
the
net
aggregate
of
the
post-tax
net
profits
(after
deducting
losses)
of
ARS,
as
determined
by
said
audited
financial
statement,
for
the
three
fiscal
years
ended
April
30,
1969,
1970
and
1971
by
$558,000
and
multiplying
the
result
by
$1,200,000.
(v)
To
each
payment
of
principal
pursuant
to
clauses
(ii),
(iii)
and
(iv)
above
there
shall
be
added
interest
thereon
at
the
rate
of
7%
per
year
from
the
Closing
Date
to
the
date
of
payment.
The
right
to
receive
payments
pursuant
to
clauses
(ii),
(iii)
and
(iv)
of
this
paragraph
shall
be
personal
to
Seller,
may
not
be
transferred
by
him
and
shall
terminate
upon
his
death
and
payments
shall
not
be
prorated
for
the
period
prior
to
his
death.
The
post-tax
net
profits
(losses)
of
ARS
for
purposes
of
the
above
payments
shall
be
determined
on
a
pro
forma
basis
as
though
ARS
had
filed
a
separate
tax
return
as
a
non-associated
Canadian
corporation
for
the
respective
years
involved.
All
audited
financial
statements
referred
to
above
shall
be
prepared
by
the
auditors
referred
to
in
paragraph
9.6
hereof.
It
will
be
seen
from
the
foregoing
provisions
that
the
price
for
the
shares
was
to
consist
of
an
initial
payment
of
$660,000
on
the
closing
date,
which
was
November
27,
1968,
and
additional
payments
based
on
the
post-tax
net
profits,
if
any,
of
ARS
as
determined
by
audited
financial
statements
for
the
fiscal
years
ending
on
April
30th
in
1969,
1970
and
1971.
The
total
of
such
additional
payments
was
not
to
exceed
$400,000
by
1969,
$800,000
by
1970,
and
$1,200,000
by
1971.
To
these
additional
payments
was
to
be
added
an
amount
specified
as
“interest”
and
provided
for
in
clause
(v)
of
paragraph
1.3
as
follows:
“To
each
payment
of
principal
pursuant
to
clauses
(il),
(iii)
and
(iv)
above
there
shall
be
added
interest
thereon
at
the
rate
of
7%
per
year
from
the
Closing
Date
to
the
date
of
payment.”
The
amount
of
$14,031.19,
which
is
in
issue
in
this
appeal,
and
the
amounts
of
$28,431.74
and
$119,262.60,
which
are
in
issue
in
appeals
A-118-78
and
A-119-78
respectively,
were
paid
pursuant
to
this
provision.
The
Minister
reassessed
the
taxpayer
on
the
basis
that
these
amounts
were
interest
within
the
meaning
of
paragraph
6(1)(b)
of
the
Income
Tax
Act
which
provides:
6.
(1)
Without
restricting
the
generality
of
section
3,
there
shall
be
included
in
computing
the
income
of
a
taxpayer
for
a
taxation
year
(b)
amounts
received
in
the
year
or
receivable
in
the
year
(depending
upon
the
method
regularly
followed
by
the
taxpayer
in
computing
his
profit)
as
interest
or
on
account
or
in
lieu
of
payment
of,
or
in
satisfaction
of
interest.
The
payments
were
held
to
be
interest
by
both
the
Tax
Review
Board
and
the
Trial
Division,
and
the
taxpayer’s
appeals
were
accordingly
dismissed.
It
is
the
appellant’s
contention
that
despite
the
name
given
to
them
in
the
agreement
the
payments
were
not
interest
but
were
part
of
the
purchase
price
and
were
therefore
not
of
an
income
nature.
The
contention
is
that
while
they
are
called
interest,
are
calculated
like
interest,
and
serve
the
purpose
of
interest,
they
lack
an
essential
characteristic
of
interest
in
that
they
did
not
accrue
from
day
to
day
on
an
existing
principal
amount.
The
principal
amount
on
which
the
sum
referred
to
as
“interest”
was
based
did
not
come
into
existence
until
it
had
been
determined
by
an
audited
financial
statement
following
the
close
of
the
fiscal
year.
Until
then
there
was
no
principal
amount
on
which
interest
could
accrue.
It
is
elementary,
of
course,
that
the
name
given
by
the
parties
to
an
amount
payable
pursuant
to
clause
(v)
of
paragraph
1.3
of
the
agreement
is
not
conclusive
of
its
nature.
See
Commissioners
of
Inland
Revenue
v
Wesleyan
&
General
Assurance
Society,
30
TC
11
at
16
and
25.
Counsel
for
the
appellant
cited
several
authorities
as
indicating
the
essential
characteristics
of
interest.
He
relied
particularly
on
what
was
said
about
the
nature
of
interest
in
the
Supreme
Court
of
Canada
in
Reference
as
to
the
Validity
of
Section
6
of
the
Farm
Security
Act,
1944,
of
the
Province
of
Saskatchewan,
[1947]
SCR
394,
and
in
The
Attorney-General
for
Ontario
v
Barfried
Enterprises
Ltd,
[1963]
SCR
570.
In
the
Saskatchewan
Farm
Security
case,
Rand,
J
defined
interest
at
411
as
“the
return
or
consideration
or
compensation
for
the
use
or
retention
by
one
person
of
a
sum
of
money,
belonging
to,
in
a
colloquial
sense,
or
owed,
to
another”,
and
at
412
he
said
that
“interest
is
referable
to
a
principal
in
money
or
an
obligation
to
pay
money.”
At
417
in
the
same
case
Kellock,
J
said,
“There
can
be
no
such
thing
as
interest
on
principal
which
is
non-existent.”
Counsel
for
the
appellant
attached
particular
importance
to
this
statement
as
expressing
the
essence
of
his
contention.
In
the
Barfried
case,
Judson,
J,
after
referring
to
the
definition
of
interest
by
Rand,
J
in
the
Saskatchewan
Farm
Security
case,
said
at
575:
“The
day-to-day
accrual
of
interest
seems
to
me
to
be
an
essential
characteristic.”
In
Tomell
Investments
Limited
v
East
Marstock
Lands
Limited,
[1978]
1
SCR
974,
Pigeon,
J
referred
at
982
and
983
to
“‘interest’
properly
so-called”
as
“a
charge
for
use
of
money
accruing
day
by
day.”
Thus
it
is
appellant’s
contention
that
the
amount
paid
pursuant
to
clause
(v)
of
paragraph
1.3
of
the
agreement
could
not
be
said
to
have
accrued
day
by
day
from
the
date
of
closing
because
there
was
no
principal
sum
in
existence
on
which
it
could
accrue
during
the
period
between
that
date
and
the
time
the
additional
sum
payable
was
determined
by
an
audited
financial
statement.
Counsel
for
the
appellant
also
relied
on
the
judgment
of
Thurlow,
J,
as
he
then
was,
in
R
G
Huston
et
al
v
MNR,
[1962]
Ex
CR
69;
[1961]
CTC
414;
61
DTC
1233,
in
which
it
was
held
that
amounts
paid
as
“interest”
on
awards
from
the
War
Claims
Fund
established
after
the
Second
World
War
were
not
interest
within
the
meaning
of
paragraph
6(b)
of
the
Income
Tax
Act.
The
awards
were
made
in
1958,
and
the
applicable
regulation
provided
that
interest
of
3%
per
annum
should
be
paid
on
the
awards
from
January
1,
1946.
Thurlow,
J
concluded
that,
although
the
amounts
were
called
interest,
were
calculated
like
interest,
and
served
the
purpose
of
interest,
they
were
not
inerest
because
during
the
period
from
January
1,
1946
to
the
date
of
the
awards
the
recipients
were
not
legally
entitled
to
a
principal
amount
upon
which
interest
could
accrue.
The
essentials
of
the
reasoning
of
Thurlow,
J
appear
to
me
to
be
continued
in
the
following
passage
from
his
reasons
at
77-78
[422,
1238]:
The
facts
are
that
the
appellant’s
property
had
been
partially
destroyed
in
1945,
a
misfortune
for
which,
so
far
as
has
been
made
to
appear,
they
had
no
right
to
legal
redress
against
anyone,
and,
in
any
event,
none
against
the
Government
of
Canada.
Vide
Civilian
War
Claimants
Association
Ltd
v
The
King
[
[1932]
AC
14].
Despite
what
was
going
on
in
the
meantime,
that
continued
to
be
the
legal
position
until
October
10,
1958,
when
the
Treasury
Board
approved
the
payments,
which
were
made
to
them
shortly
afterwards.
No
principal
sum
was
payable
in
the
meantime,
nor
was
interest
accruing
on
any
principal
sum,
nor
were
the
appellants
being
kept
out
of
any
sum
to
which
they
were
entitled.
In
truth,
during
the
whole
of
the
intervening
period
they
had
no
right
to
compensation
for
their
loss,
and
there
was
neither
interest
accruing
to
them
nor
loss
of
revenue
being
sustained
in
respect
to
which
they
would
be
entitled
to
interest
by
way
of
damages
or
compensation.
Thurlow,
J
added
the
following
observations
at
78
[423,
1238],
which
counsel
for
the
appellant
found
particularly
helpful
to
his
contention:
In
this
connection,
it
may
be
noted
that,
while
the
House
of
Lords
in
Riches
v
Westminster
Bank
[[1947]
1
All
ER
469]
overruled
Re
National
Bank
of
Wales
[
[1899]
2
Ch
629],
it
did
not
overrule
Commissioner
of
Inland
Revenue
v
Ballantine
[(1921)
8
TC
595]
or
Simpson
v
Executors
of
Bonner
Maurice
[(1920)
14
TC
580]
both
of
which
appear
to
me
to
be
stronger
cases
in
this
respect
than
the
present
for
attributing
an
income
nature
to
the
sums
in
question,
since
in
these
cases
the
taxpayer’s
right
to
the
sum
to
which
“interest”
was
added
arose
prior
to
or
at
the
commencement
of
the
period
in
respect
to
which
the
“interest”
was
computed.
No
case
of
which
I
am
aware
goes
so
far
as
to
hold
such
an
amount,
call
it
interest
or
damages
or
compensation
or
any
other
name,
to
be
interest
or
income
when
there
was
neither
interest
accruing
in
fact
on
the
“principal”
amount
during
the
material
period
nor
any
right
to
the
“principal”
amount
vested
in
the
taxpayer
during
that
period.
In
the
Bonner
Maurice
case,
to
which
Thurlow,
J
referred,
it
was
held
that
an
amount
awarded
as
compensation
under
the
terms
of
the
Peace
Treaty
for
interference
with
the
disposition
of
property
during
the
First
World
War,
and
computed
on
the
basis
of
interest,
was
not
interest
for
purposes
of
income
tax.
Rowlatt,
J,
whose
judgment
was
affirmed
by
the
Court
of
Appeal,
said
at
593:
The
Treaty
gave
compensation,
and
the
tribunal
which
assessed
the
principal
sum
has
assessed
it
on
the
basis
of
interest.
I
think
this
sum
first
came
into
existence
by
the
Award,
and
no
previous
history
or
anterior
character
can
be
attributed
to
it.
The
Riches
case,
to
which
Thurlow,
J
also
referred,
was
one
on
which
counsel
for
the
appellant
placed
particular
emphasis.
In
that
case
the
issue
was
whether
interest
awarded
as
damages
by
a
judgment
for
failure
to
pay
a
sum
owing
when
it
should
have
been
paid
was
income
for
purposes
of
income
tax.
It
was
held
that
it
was,
the
principal
issue
being
whether
there
was
any
incompatibility
between
the
notion
of
damages
and
the
notion
of
interest.
In
that
case
the
principal
sum
was
owing
on
the
date
from
which
interest
ran,
which
distinguishes
it
from
the
present
case.
It
was
also
argued
that
the
sum
awarded
as
interest
could
not
be
interest
because
it
had
not
in
fact
accrued
from
day
to
day
but
had
been
awarded
from
a
past
date.
This
argument
was
rejected
on
the
ground,
as
I
understand
the
reasons,
that
the
damage
for
which
interest
was
awarded
had
in
fact
accrued
or
been
incurred
from
day
to
day.
I
do
not
find
that
the
Riches
case
really
answers
the
question
in
the
present
case.
In
the
present
case
there
was
in
existence
on
the
closing
date
an
obligation
to
pay
a
price
to
be
determined
according
to
the
formula
set
out
in
paragraph
1.3
of
the
agreement,
but
the
precise
amounts
of
the
additional
payments,
if
any,
to
be
made
pursuant
to
clauses
(ii),
(iii)
and
(iv)
were
not
determined
as
of
that
date.
The
obligation
to
pay
additional
sums
on
account
of
the
purchase
price
under
these
provisions
was
a
conditional
one
or
a
contingent
liability.
It
depended
on
two
conditions
which
might
or
might
not
be
fulfilled.
There
had
to
be
post-tax
net
profits
determined
by
audited
financial
statements,
and
the
seller
had
to
be
living.
Neither
was
a
certainty.
That
was
sufficient
to
make
the
liability
for
additional
payments
a
contingent
one.
Unless
and
until
these
conditions
were
fulfilled
there
could
not
be
an
additional
sum
owing
pursuant
to
clauses
(ii),
(iii)
or
(iv)
of
paragraph
1.3
Reference
was
made
in
the
course
of
argument
to
various
cases
indicating
the
nature
of
a
contingent
liability,
in
particular,
Winter
v
IRC,
[1963]
AC
235,
in
which
the
issue
was
whether
a
liability
to
pay
tax
on
recaptured
capital
cost
allowance
was
a
contingent
liability
within
the
meaning
of
the
applicable
statutory
provision.
Both
Lord
Reid
and
Lord
Guest
quoted
from
a
passage
in
Erskine’s
Institute
of
the
Laws
of
Scotland
concerning
the
nature
of
a
conditional
obligation
under
Scots
law,
on
the
apparent
assumption
that
it
was
equally
true
of
a
contingent
liability
under
English
law.
The
definition
of
conditional
obligation
in
Erskine
reads
as
follows:
A
conditional
obligation,
or
an
obligation
granted
under
a
condition,
the
existence
of
which
is
uncertain,
has
no
obligatory
force
till
the
condition
be
purified;
because
it
is
in
that
event
only
that
the
party
declares
his
intention
to
be
bound,
and
consequently
no
proper
debt
arises
against
him
till
it
actually
exists;
so
that
the
condition
of
an
uncertain
event
suspends
not
only
the
execution
of
the
obligation,
but
the
obligation
itself.
What
results
from
the
discussion
of
a
conditional
obligation
or
contingent
liability
in
the
Winter
case
is
that
while
the
debtor
cannot
withdraw
his
undertaking
there
is
no
obligation
or
liability
to
pay
unless
and
until
the
condition
is
fulfilled
or
the
contingency
occurs.
The
definitions
of
contingent
liability
in
Winter
were
applied
by
this
Court
in
L
H
Mandel
v
The
Queen,
[1979]
1
FC
560;
[1978]
CTC
780;
78
DTC
6518,
to
the
liability,
on
the
sale
of
a
film,
for
the
balance
of
price
which
was
to
be
payable
out
of
earnings,
a
case
obviously
analogous
to
the
present
one.
Ryan,
J
said
of
the
liability
for
the
balance
of
price
at
566
[785,
6521]:
It
was
not,
however,
as
to
the
balance,
a
liability
to
pay
merely
on
the
expiration
of
a
period
of
time
or
on
the
happening
of
a
certain
event
that
was
certain,
or
even
likely,
to
occur.
It
was
a
liability
(from
which
the
purchasers
admittedly
could
not
unilaterally
withdraw)
to
become
subject
to
an
obligation
to
pay
the
balance
if,
but
only
if,
an
event
occurred
which
was
by
no
means
certain
to
occur.
The
obligation
was
thus
contingent
on
the
happening
of
the
uncertain
event.
What
these
cases
do
not
touch
on,
and
what
appears
to
be
the
issue
in
the
present
case,
is
the
effect,
in
so
far
as
the
essential
characteristics
of
interest
are
concerned,
that
should
be
given
to
the
fulfilment
of
the
condition
which
makes
the
liability
absolute.
The
learned
trial
judge
concluded
that
the
fulfilment
of
the
condition
had
a
retroactive
effect.
This
conclusion
is
contained
in
the
following
passage
from
his
reasons:
Once
it
was
ascertained
that
the
profits
had
been
made
and
could
be
calculated
and
the
vendor
was
still
alive
his
obligation
for
the
payments
in
each
of
the
years
1969,
1970
and
1971
became
due,
and
the
condition
having
been
fulfilled
it
had
a
retroactive
effect
to
the
date
of
the
contract.
Interest
ran
from
that
day
on
the
payments
due
in
accordance
with
the
terms
of
the
contract.
He
based
this
conclusion
on
the
assumption
that
the
common
law
as
to
the
effect
of
the
occurrence
of
a
contingency
did
not
differ
in
principle
from
the
rule
in
article
1085
of
the
Quebec
Civil
Code
that
“The
fulfilment
of
the
condition
has
a
retroactive
effect
from
the
day
on
which
the
obligation
has
been
contracted.”
In
my
respectful
opinion,
this
was
not
an
unreasonable
assumption,
given
what
was
said
in
Winter
about
the
probable
similarity
of
a
conditional
obligation
under
Scots
law
and
a
contingent
liability
under
English
law,
and
the
common
origin,
in
Roman
law,
of
both
Scots
law
and
Quebec
law
with
respect
to
a
conditional
obligation.
I
note,
for
example,
that
while
Erskine
did
not
deal
specifically
with
retroactive
effect,
he
mentioned
the
rule,
derived
from
Roman
law,
which
is
also
found
in
the
second
part
of
article
1085
of
the
Quebec
Civil
Code,
that
the
right
created
by
a
conditional
obligation
is
transmitted
on
death.
This
rule
was
treated
by
Pothier,
one
of
the
sources
consulted
by
the
Quebec
codifiers
for
article
1085
(see
de
Lorimier,
Bibliothèque
du
Code
civil,
v
8,
p
417),
as
a
corollary
of
the
retroactive
effect
of
fulfilment
of
the
condition.
In
any
event,
given
that
such
an
effect
is
not
clearly
excluded
by
what
we
are
able
to
ascertain
from
the
cases
of
the
common
law
concerning
contingent
liability,
it
is
my
opinion
that
it
was
open
to
the
parties
to
the
agreement
of
sale
in
this
case
to
treat
the
occurrence
of
the
contingency
as
having
such
effect,
in
so
far
as
interest
was
concerned.
Cf.
Trollope
&
Colls,
Ltd
et
al
v
Atomic
Power
Constructions,
Ltd,
[1962]
3
All
ER
1035,
in
which
it
was
held
that
parties
to
a
contract
could
give
their
contract
retrospective
effect.
There
is
no
rule
of
law
that
prevented
them
from
treating
an
additional
sum
payable
on
account
of
the
purchase
price
under
the
terms
of
clauses
(ii),
(iii)
or
(iv)
of
paragraph
1.3
of
the
agreement
as
owing,
for
purposes
of
interest,
from
the
closing
date,
as
they
appear
to
have
done
in
clause
(v).
There
were
sound
business
reasons
for
doing
so
since
the
sale
had
been
concluded
on
that
date
and
the
over-all
obligation
to
pay
the
purchase
price
contracted
on
that
date.
Because
of
the
basis
on
which
the
balance
of
price,
if
any,
was
to
be
determined,
the
seller
was
obliged
to
wait
for
payment
of
the
balance.
Interest
was
the
appropriate
compensation
for
that
delay.
I
think
it
is
the
existence
on
the
closing
date
of
a
conditional
obligation
or
contingent
liability
to
pay
the
balance
of
price
which
the
parties
were
entitled
to
treat
as
having
become
absolute
with
retroactive
effect,
for
purposes
of
interest,
that
distinguishes
the
present
case
from
Huston.
For
these
reasons
I
am
of
the
opinion
that
the
payment
of
$14,031.19
received
by
the
late
Mr
Perini
in
the
taxation
year
1969
was
interest,
and
therefore
income,
and
the
appeal
should
accordingly
be
dismissed
with
costs.
