Heald,
J
(concurred
in
by
Urie,
J
and
MacKay,
DJ)
(judgment
delivered
from
the
Bench):—This
is
an
appeal
from
a
judgment
of
the
Trial
Division
in
which
the
learned
trial
judge
held
that
the
respondent,
as
represented
by
the
Minister
of
National
Revenue,
correctly
assessed
the
plaintiff
interest
in
respect
of
deferred
tax
payable
by
the
Estate
of
Robin
Ellis
Agnew,
who
died
on
May
1,
1973.
An
agreed
statement
of
facts
filed
at
trial
establishes
that
the
plaintiff
filed
an
income
tax
return
for
that
portion
of
the
year
1973
in
which
the
said
Agnew
was
alive
and
reported
thereon
gains
on
deemed
disposition
of
capital
property
as
required
by
paragraph
70(5)(a)
of
the
Income
Tax
Act,
SC
1970-71-72,
c
63,
as
amended
by
SC
1973-74,
c
14,
subsection
19(1).
The
plaintiff
elected,
under
subsection
159(5)
of
the
Act,*
to
defer
payment
of
the
tax
attributable
to
the
increase
in
taxable
income
by
reason
of
the
application
of
paragraph
70(5)(a).
The
election
to
defer
payment
was
made
on
June
25,
1974.
An
Order-in-Councilf
was
published
in
the
Canada
Gazette
of
July
24,
1974,
in
which,
inter
alia,
the
Income
Tax
Regulations
were
amended
as
follows:
5.
(1)
Subsection
4300(1)
of
the
said
Regulations
is
revoked
and
the
following
substituted
therefor:
“4300.
(1)
A
rate
of
interest
at
6%
per
annum
is
hereby
prescribed
(a)
for
the
purposes
of
subsection
159(7)
.
.
.
of
the
Act;
.
.
.”
(2)
Subsection
4300(1)
of
the
said
Regulations,
as
enacted
by
subsection
(1)
of
this
section,
is
effective
on
and
after
(a)
December
23,
1971,
in
respect
of
the
provisions
referred
to
in
paragraph
(a)
thereof;
.
.
.
The
predecessor
Regulation
4300(1)
which
was
in
effect
on
June
25,
1974,
the
date
of
the
election
in
this
case,
was
not
made
applicable
to
section
159
of
the
Act.
The
position,
therefore,
as
at
June
25,
1974
was
that
no
interest
was
payable
under
section
159.
Subsections
159(5)
and
159(7)
were
added
to
the
Income
Tax
Act
by
virtue
of
section
58
of
the
1973-74
amending
Act
on
April
18,
1973,
which
reads
as
follows:
08.
(1)
Section
159
of
the
Act
is
amended
by
adding
thereto
the
following
subsections:
“(5)
Where
subsection
70(2)
or
(5)
is
applicable
in
respect
of
a
taxpayer
who
has
died,
and
the
taxpayer’s
legal
representative
so
elects
and
furnishes
to
the
Minister
security
acceptable
to
the
Minister
for
payment
of
any
tax
the
payment
of
which
is
deferred
by
the
election,
whether
such
security
is
by
way
of
a
charge
of
any
kind
on
property
that
was
property
of
the
taxpayer
or
is
property
of
any
other
person
or
by
way
of
guarantee
from
any
other
person,
notwithstanding
any
provision
of
this
Part
or
the
Income
Tax
Application
Rules,
1971
respecting
the
time
within
which
payment
shall
be
made
of
the
tax
payable
under
this
Part
by
the
taxpayer
for
the
taxation
year
in
which
he
died,
all
or
any
portion
of
such
part
of
that
tax
as
is
equal
to
the
amount,
if
any,
by
which
that
tax
exceeds
the
amount
that
that
tax
would
be,
if
this
Act
were
read
without
reference
to
subsections
70(2)
and
(5),
may
be
paid
in
such
number
(not
exceeding
6)
of
equal
consecutive
annual
instalments
as
is
specified
by
the
legal
representative
in
the
election,
the
first
instalment
of
which
shall
be
paid
on
or
before
the
day
on
or
before
which
payment
of
that
tax
would,
but
for
the
election,
have
been
required
to
be
made
and
each
subsequent
instalment
of
which
shall
be
paid
on
or
before
the
next
following
anniversary
of
that
day.
(7)
Every
election
made
by
a
taxpayer
under
subsection
(4)
or
by
the
legal
representative
of
a
taxpayer
under
subsection
(5),
as
the
case
may
be,
shall
be
made
by
him
in
prescribed
form
and
in
prescribed
manner,
and
on
condition
of
payment,
at
the
time
of
payment
of
any
amount
the
payment
of
which
is
deferred
by
the
election,
of
interest
on
that
amount,
at
the
rate
per
annum
prescribed
for
the
purposes
of
this
subsection
at
the
time
of
the
making
of
the
election,
from
the
day
on
or
before
which
payment
of
that
amount
would,
but
for
the
election,
have
been
required
to
be
made
to
the
day
of
payment
thereof.”
(2)
This
section
is
applicable
to
the
1972
and
subsequent
taxation
years.
Accordingly
the
issue
in
the
Trial
Division
and
in
the
argument
before
us
was
whether
the
new
Income
Tax
Regulation
4300(1)
made
effective
by
the
Order-in-Council
of
July
24,
1974
was,
in
so
far
as
it
applies
to
subsection
159(7)
of
the
Income
Tax
Act,
applicable
to
the
payments
of
income
tax
deferred
and
payable
by
instalment
in
respect
of
an
election
made
on
June
25,
1974
in
respect
of
the
1973
taxation
year
pursuant
to
subsection
159(5)
of
the
Income
Tax
Act.
Put
another
way,
the
question
for
decision
on
the
facts
of
this
case
is
whether
the
Income
Tax
Act
and
regulations
authorize
the
imposition
of
the
6%
interest
rate
invoked
by
new
Regulation
4300(1)
in
respect
of
an
election
made
prior
to
the
said
regulation
coming
into
effect.
The
learned
trial
judge
held
that
by
virtue
of
section
58
of
the
1973-74
amendment
and
subsection
221(2)
of
the
Income
Tax
Act,*
the
authority
given
the
Governor-in-Council
under
subsection
159(7),
to
prescribe
a
rate
of
interest
for
purposes
of
that
section,
is
properly
retroactive
to
the
date
of
the
election
made
in
this
case.
With
respect,
it
is
our
Opinion
that
he
erred
in
coming
to
that
conclusion.
When
new
Regulation
4300(1)
is
considered
in
the
light
of
the
provisions
of
subsection
159(7),
it
is
clear
that
the
regulation
does
not
apply
to
elections
made
prior
to
July
24,
1974
because
the
section
calls
for
the
payment
of
interest
‘‘at
the
rate
per
annum
prescribed
for
the
purposes
of
this
subsection
at
the
time
of
the
making
of
the
election”,t
In
this
case
the
election
was
made
on
June
25,
1974.
On
June
25,
1974
no
rate
of
interest
per
annum
had
been
prescribed.
Therefore,
giving
to
the
words
used
in
subsection
159(7)
their
plain
and
unambiguous
meaning,
it
is
our
view
that
no
interest
can
be
charged
in
the
circumstances
of
this
case.
In
respect
of
elections
made
after
July
24,
1974,
it
would
seem
to
us
that
interest
at
6%
could
be
charged
by
virtue
of
the
combined
operation
of
new
Regulation
4300(1),
and
subsection
159(7)
and
subsection
221(2)
of
the
Income
Tax
Act.
Respondent’s
counsel
submitted
(and
the
trial
judge
so
held)
that
subsection
221(2)
of
the
Act
operates
so
as
to
give
to
new
Regulation
4300(1)
retrospective
effect
back
to
the
date
of
the
election
in
this
case.
We
do
not
agree.
Subsections
221(2)
and
159(7)
of
the
Act
should,
if
possible,
be
read
so
as
to
be
consistent
the
one
with
the
other.
If
subsection
221(2)
is
read
in
the
manner
urged
upon
us
by
the
respondent,
then
the
result
is
to
render
the
words
“at
the
time
of
the
making
of
the
election’’
as
used
in
subsection
159(7)
meaningless
and
of
no
effect.
The
Court
will
avoid
such
a
construction
if
at
all
possible.
The
Court
will
also,
particularly
in
taxation
cases,
and
where
the
legislation
is
capable
of
two
interpretations,
the
one
retrospective
and
the
other
not,
refrain
from
applying
the
retrospective
interpretation.*
Looking
at
the
applicable
sections
of
the
Act
and
the
regulations,
it
is
our
view
that
the
proper
application
and
interpretation
of
new
Regulation
4300(1)
is
that
interest
at
6%
is
chargeable
under
subsection
159(7)
in
respect
of
the
1972
and
subsequent
taxation
years
but
only
in
respect
of
elections
made
on
and
after
July
24,
1974.
Such
an
interpretation
considers
new
Regulation
4300(1)
in
the
context
of
both
subsection
221(2)
and
subsection
159(7).
Such
an
interpretation
would
also
avoid
the
chaotic
and
unfair
situation
which
might
well
result
if
there
were
no
restrictions
on
the
retroactivity
of
new
Regulation
4300(1).
As
was
pointed
out
by
appellant’s
counsel
both
in
his
memorandum
and
in
oral
argument,
if
the
regulation
is
construed
so
as
to
apply
to
elections
made
before
July
24,
1974
in
respect
of
the
1972
and
1973
taxation
years,
no
executor
could
reasonably
make
an
informed
decision
on
election
since
he
would
be
making
the
estate
liable
for
interest
which
could
be
increased
without
limit
after
the
election
had
been
made.
Such
a
chaotic
and
unfair
result
cannot
be
presumed
to
have
been
intended
by
Parliament
except
by
the
use
of
clear
and
unambiguous
language.
Likewise,
a
statute
should
not
be
construed
so
as
to
have
a
greater
retrospective
operation
than
its
language
renders
necessary.f
Having
regard
to
all
of
these
considerations
it
is
our
opinion
that
new
Regulation
4300(1)
should
be
construed
as
only
having
retrospective
operation
with
respect
to
elections
under
subsection
159(7)
made
from
and
after
July
24,
1974.
On
this
basis,
the
appeal
must
succeed.
We
would,
accordingly,
allow
the
appeal
and
set
aside
the
judgment
of
the
Trial
Division
and
direct
that
the
notice
of
reassessment
dated
February
3,
1975
be
varied
by
deleting
therefrom
the
interest
charged.
We
would
further
direct
the
payment
of
the
appellant’s
costs
both
here
and
in
the
Trial
Division.
