as violating Charter, ss. 7 and 8 — Warrants issued there-
under invalid. 
Constitutional law — Charter of Rights — Criminal process 
— Income Tax Act, s. 231.3 search and seizure provisions in 
violation of Charter, s. 8 — Not meeting express or implied 
criteria set by S.C.C. in Southam for reasonable search and 
seizure by: (1) denying judicial discretion to refuse to issue 
search warrant or to attach conditions thereto; (2) using words 
diluting standard with respect to probability of finding 
evidence. 
Constitutional law — Charter of Rights — Life, liberty and 
security — Income Tax Act, s. 231.3 search and seizure 
provisions in violation of Charter, s. 7 as denial of judicial 
discretion therein contrary to principles of fundamental 
justice. 
Practice — Privilege — Accountant-client privilege not 
protected in federal income tax litigation. 
Searches and seizures were effected on the authority of 
warrants issued under section 231.3 of the Income Tax Act. 
The Trial Division dismissed the appellant's attacks on the 
warrants themselves and on the validity of the section under 
which they were issued. 
This was an appeal from that decision. 
Held, the appeal should be allowed, the warrants quashed 
and section 231.3 declared of no force or effect because it was 
inconsistent with sections 7 and 8 of the Charter. 
The search and seizure procedures authorized by section 
231.3 were criminal in their nature. The section was concerned 
with the detection and prosecution of crime. Nothing less than 
the full panoply of Charter protection was therefore 
appropriate. 
The words "A judge shall issue the warrant" in subsection 
231.3(3) specifically excluded judicial discretion in the issuance 
of search warrants. For that reason, that provision ran afoul of 
sections 7 and 8 of the Charter as authorizing an unreasonable 
search and seizure and violating the principles of fundamental 
justice. 
The word "shall" is normally imperative, and should be 
interpreted in that manner unless such an interpretation would 
be utterly inconsistent with the context in which it has been 
used and would render the sections irrational or meaningless. 
There was nothing in the section to suggest that "shall" should 
not be given its normal imperative meaning. Nor could the Bill 
of Rights be used to validate, by interpretation, legislation 
which was otherwise inadequate on Charter grounds. 
The Court's power to control abuse of process or to add 
conditions to a warrant could not be invoked. If the conditions 
precedent to a reasonable search and seizure were exhaustively 
set out in subsection 231.3(3), an application meeting those 
conditions could not be an abuse of process. And if the word 
"shall" was given its normal imperative meaning, there could 
be no power in the judge to attach conditions to the warrant 
beyond those specifically set out in the statute. 
The requirement of judicial discretion to refuse to issue a 
search warrant, or to attach conditions to a warrant when 
issued, was implicit in the standards of reasonability set out by 
the Supreme Court of Canada in Hunter et al. v. Southam Inc. 
as a prerequisite to a reasonable search and seizure in accord
ance with section 8 of the Charter. 
The Supreme Court of Canada decision in Descôteaux et al. 
v. Mierzwinski was authority for the proposition that the 
attaching of conditions to a search warrant was a necessary and 
essential part of the exercise of judicial discretion but, even 
more importantly, that the very existence of such discretion was 
a prerequisite to the reasonableness of the search and to our 
notions of fundamental justice. 
The use of the phrase "reasonable grounds to believe" 
instead of "reasonable and probable" was of no consequence. In 
that phrase, "probable" added nothing. Like the second 
member of such other hallowed English legal phrases as "null 
and void", "good and valid", "last will and testament", it did 
nothing. Furthermore, a grammatical analysis of subsection 
231.3(3) showed that in fact, the evidentiary burden of "more 
likely than not" has been met or exceeded. 
Also, on the basis of Southam, the text of paragraph 
231.3(3)(b) (a document or thing that may afford evidence) 
was inadequate on Charter grounds and was therefore inopera
tive: the use of the word "may" allowed the issuance of a search 
warrant on showing of reasonable grounds to believe in a mere 
possibility that the thing to be found would afford evidence of a 
crime. 
As to subsection 231.3(5), this Court had already decided in 
Solvent Petroleum that it met the test of reasonableness and 
therefore of validity. There was no good reason to revisit that 
finding. 
Accountant-client privilege was not protected in the context 
of federal income tax litigation. Solicitor-client privilege was on 
a different footing as necessary for the proper administration of 
justice, but in this case there had been no breach of that 
privilege since the proper procedure to protect it was followed 
during the execution of the warrants.

The following are the reasons for judgment 
rendered in English by 
HUGESSEN J.A.: 
Introduction 
These four appeals are from judgments of the 
Trial Division [[1990] 2 F.C. 262] dismissing a 
series of attacks upon searches and seizures effect
ed on the authority of warrants issued under sec
tion 231.3 of the Income Tax Act [S.C. 1970-71-
72, c. 63 (as am. by S.C. 1986, c. 6, s. 121)]. 
Three of the proceedings in the Trial Division 
attacked the warrants themselves while the fourth 
sought a declaration of invalidity of the statutory 
provisions under which they were issued. All raised 
the same questions and were dealt with by a single 
set of reasons in the Trial Division. It is convenient 
to do likewise here. 
For ready reference I reproduce here in its 
entirety the statutory text under which the search 
warrants were issued and which lies at the centre 
of this litigation: 
231.3 (1) A judge may, on ex parte application by the 
Minister, issue a warrant in writing authorizing any person 
named therein to enter and search any building, receptacle or 
place for any document or thing that may afford evidence as to 
the commission of an offence under this Act and to seize and, 
as soon as practicable, bring the document or thing before, or 
make a report in respect thereof to, the judge or, where the 
judge is unable to act, another judge of the same court to be 
dealt with by the judge in accordance with this section. 
(2) An application under subsection (1) shall be supported 
by information on oath establishing the facts on which the 
application is based. 
(3) A judge shall issue the warrant referred to in subsection 
(1) where he is satisfied that there are reasonable grounds to 
believe that 
(a) an offence under this Act has been committed; 
(b) a document or thing that may afford evidence of the 
commission of the offence is likely to be found; and 
(c) the building, receptacle or place specified in the applica
tion is likely to contain such a document or thing. 
(4) A warrant issued under subsection (1) shall refer to the 
offence for which it is issued, identify the building, receptacle 
or place to be searched and the person alleged to have commit
ted the offence and it shall be reasonabLy specific as to any 
document or thing to be searched for and seized. 
(5) Any person who executes a warrant under subsection (1) 
may seize, in addition to the document or thing referred to in 
subsection (1), any other document or thing that he believes on 
reasonable grounds affords evidence of the commission of an 
offence under this Act and shall as soon as practicable bring 
the document or thing before, or make a report in respect 
thereof to, the judge who issued the warrant or, where the 
judge is unable to act, another judge of the same court to be 
dealt with by the judge in accordance with this section. 
(6) Subject to subsection (7), where any document or thing 
seized under subsection (1) or (5) is brought before a judge or a 
report in respect thereof is made to a judge, the judge shall, 
unless the Minister waives retention, order that it be retained 
by the Minister, who shall take reasonable care to ensure that it 
is preserved until the conclusion of any investigation into the 
offence in relation to which the document or thing was seized 
or until it is required to be produced for the purposes of a 
criminal proceeding. 
(7) Where any document or thing seized under subsection 
(I) or (5) is brought before a judge or a report in respect 
thereof is made to a judge, the judge may, of his own motion or 
on summary application by a person with an interest in the 
document or thing on three clear days notice of application to 
the Deputy Attorney General of Canada, order that the docu
ment or thing be returned to the person from whom it was 
seized or the person who is otherwise legally entitled thereto if 
the judge is satisfied that the document or thing 
(a) will not be required for an investigation or a criminal 
proceeding; or 
(b) was not seized in accordance with the warrant or this 
section. 
(8) The person from whom any document or thing is seized 
pursuant to this section is entitled, at all reasonable times and 
subject to such reasonable conditions as may be imposed by the 
Minister, to inspect the document or thing and to obtain one 
copy of the document at the expense of the Minister. 
The Nature of the Search and Seizure Authorized 
by Section 231.3 
As a preliminary matter, it is as well to make 
clear at the outset that in my opinion we are 
dealing with procedures that are criminal in their 
nature. It is not necessary at this stage to charac
terize in constitutional terms the source of Parlia
ment's legislative power, a question on which the 
Supreme Court has recently divided and which 
awaits a definitive resolution by a majority of the 
members of that Court (see Knox Contracting Ltd. 
v. Canada, [1990] 2 S.C.R. 338). 
It is enough simply to read the section under 
attack and its repeated reference to "offence" to 
realize that the section is concerned with the 
detection and prosecution of crime, albeit a limited 
category of crime, namely offences under the 
Income Tax Act. This makes the legislation differ
ent in kind from the type of administrative 
enforcement mechanisms found in adjacent sec
tions of the Income Tax Act such as were upheld 
by the Supreme Court in R. v. McKinlay Trans
port Ltd., [1990] 1 S.C.R. 627. 
The requirements of a self-reporting and self-
assessing income tax system may justify an easing 
of Charter [Canadian Charter of Rights and 
Freedoms, being Part I of the Constitution Act 
1982, Schedule B, Canada Act, 1982, 1982, c. 11 
(U.K.) [R.S.C., 1985, Appendix II, No. 44]] 
standards where the primary purpose of a search is 
simply to ensure that taxes are paid as and when 
due. Where as here, however, we are dealing with 
provisions whose stated aim is the discovery and 
preservation of evidence "for the purpose of a 
criminal proceeding" nothing less than the full 
panoply of Charter protection is appropriate. 
With that background in mind, I now turn to 
those grounds of attack argued by the appellants 
with regard to which we called on the respondents 
to reply. 
The Denial of Judicial Discretion in the Issuance 
of the Search Warrant 
The appellants' first and most serious attack 
concentrates on the use of the word "shall" in the 
first line of subsection 231.3(3). The appellants 
say, and the respondents admit, that this is unique 
in the Canadian statute book; all other texts pur
porting to authorize a judicial officer to issue a 
search warrant are couched in permissive lan
guage, leaving to that officer the ultimate discre
tion as to whether or not the circumstances justify 
an invasion of privacy. Any text which specifically 
excludes such residual judicial discretion in the 
issuance of a search warrant will, for that reason 
alone, run afoul of sections 7 and 8 of the Charter 
as authorizing an unreasonable search and seizure 
and one that is in breach of the principles of 
fundamental justice. I agree. 
There can be no doubt that the use of the word 
"shall" is normally imperative. 
Furthermore, this Court, in dealing with pre
cisely the same statutory provision, has already 
held that the words of subsection 231.3(3) leave no 
discretion in the judge. In Solvent Petroleum 
Extraction Inc. v. M.N.R., 2 Desjardins J.A., 
speaking for the Court, said [at page 24]: 
Subsection 231.3(1) states that "A judge may". Subsection 
231.3(3) states that "A judge shall". It would therefore appear 
from the language of subsection 231.3(3) that if the issuing 
judge comes to the conclusion that the conditions of paragraphs 
231.3(3)(a), (b) and (c) are met, he need not nor is he 
permitted to consider whether there has been a previous sub
stantive voluntary compliance by the taxpayer, whether further 
documents might be remitted voluntarily, or whether the appli
cant for the warrants has taken all reasonable steps to obtain 
the information from an alternative source before applying for 
the warrants. In brief, if the conditions are met, he must issue 
the warrant. 
The respondents, for their part, argue that the 
following passage from the Trial Judge's reasons is 
a better reading of the law and should now be 
followed [at pages 274-275]: 
If it is clear that the intention of Parliament was to leave 
discretion in a judge to refuse to issue a warrant when the 
search would offend section 8 of the Charter, then that inter
pretation would prevail, over the general rule of interpretation 
set out in section 11 of the Interpretation Act. 
There is considerable jurisprudence which holds that "shall" 
can be either directory or mandatory. This jurisprudence might 
be relevant to the interpretation of subsection 231.3(3). More 
importantly, however, the Canadian Bill of Rights [R.S.C., 
1985, Appendix III] might play a role so as to require subsec
tion 231.3(3) to be interpreted so as to preserve for a judge 
discretion, to refuse warrants, in the case of abusive searches 
and seizures. Section 2 of that Act when read together with 
section 1 requires: 
See section 11 of the Interpretation Act, R.S.C., 1985, c. 
I-21. 
2 [1990] 1 F.C. 20 (C.A.). 
Every law of Canada shall ... be so construed and applied as 
not to abrogate, abridge or infringe ... the right of the 
individual to life, liberty, security of the person ... 
Alternatively the Court's inherent power to control the abuse of 
its own process might operate to enable a judge to refuse to 
issue an abusive warrant. See generally: R. v. Young (1984), 46 
O.R. (2d) 520; 13 C.C.C. (3d) 13 O.A.C. 254 (C.A.); R. v. 
Miles of Music Ltd. (1989), 48 C.C.C. (3d) 96 (Ont. C.A.) 
and section 50 of the Federal Court Act [R.S.C., 1985, c. F-7]. 
These are all speculative arguments, however, and have not 
been addressed by counsel. Certainly, it seems to me a judge 
would strive against issuing an abusive warrant which offended 
section 8 of the Charter, if he or she knew, at the time the 
request was made, that the warrant was abusive. At the very 
least, I do not think subsection 231.3(3) precludes a judge from 
adding terms and conditions to a warrant sought. There is 
nothing in subsection 231.3(3) which says that a judge must 
issue a warrant in the exact terms in which it is sought. 
With respect, it seems to me that there are 
several things wrong with the interpretation pro
posed by the Trial Judge. 
In the first place, and if I understand her cor
rectly, what she is suggesting in the first part of 
the quoted passage is precisely the kind of "read-
ing down" against which the Supreme Court has 
warned. 3 
Secondly, while there is indeed "considerable 
jurisprudence" going back to the old case of Julius 
v. Bishop of Oxford (1880), 5 App. Cas. 214 
(H.L.), to the effect that words of empowerment 
("may") can in certain circumstances import obli
gation ("shall"), there is very little the other way 
round: "shall" is rarely interpreted to mean 
"may". 
We are here dealing not with a piece of subordi
nate legislation or a statutory instrument but with 
the constitutional scrutiny of a text adopted by 
Parliament itself. As was said by the Supreme 
Court of Canada in the Reference re Manitoba 
Language Rights, [1985] 1 S.C.R. 721 [at page 
737]: 
As used in its normal grammatical sense, the word "shall" is 
presumptively imperative. See Odgers' Construction of Deeds 
and Statutes (5th ed. 1967) at p. 377; The Interpretation Act, 
1867 (Can.), 31 Vict., c. 1, s. 6(3); Interpretation Act, R.S.C. 
1970, c. I-23, s. 28 ("shall is to be construed as imperative"). It 
See for example Hunter et al. v. Southam Inc., [ 1984] 2 
S.C.R. 145, at p. 168. 
is therefore incumbent upon this Court to conclude that Parlia
ment, when it used the word "shall" in s. 23 of the Manitoba 
Act, 1870 and s. 133 of the Constitution Act, 1867, intended 
that those sections be construed as mandatory or imperative, in 
the sense that they must be obeyed, unless such an interpreta
tion of the word "shall" would be utterly inconsistent with the 
context in which it has been used and would render the sections 
irrational or meaningless. See, e.g. Re Public Finance Corp. 
and Edwards Garage Ltd. (1957), 22 W.W.R. 312, p. 317 
(Alta. S.C.) [Emphasis added.] 
There is, as it seems to me, absolutely nothing in 
the context of section 231.3 of the Income Tax Act 
which would render an imperative interpretation of 
the word "shall" in subsection 231.3(3) inconsist
ent with the balance of the section or make it 
irrational or meaningless. Indeed, I can see noth
ing in the section which would point to a permis
sive or discretionary meaning for "shall". On the 
contrary, the draughtsman has clearly used the 
permissive "may" where this is appropriate (as for 
example in subsections 231.3(1) and (5)) and the 
use of "shall" in subsection 231.3(3) (as well, it 
may be noted, as in subsection 231.3(6)) has every 
appearance of being a deliberate choice. 
Furthermore, the whole of section 231.3 repre
sents a change from the previous law 4 which was 
couched in terms that were clearly permissive and 
left a discretion in the hands of the judge authoriz
ing the seizure. Also, as noted above, the text of 
subsection 231.3(3) is unique and differs remark
ably from all other Canadian search warrant 
provisions.' I cannot view such a change from both 
previous and current practice as being anything 
but intentional. 
4 The former subsection 231(4) which was struck down by 
this Court as not meeting Charter standards on other grounds: 
see Minister of National Revenue v. Kruger Inc., [ 1984] 2 F.C. 
535 (C.A.). 
5 The most notable is of course subsection 4870) of the 
Criminal Code [R.S.C., 1985, c. C-46 (as am. by R.S.C., 1985 
(1st Supp.), c. 27, s. 68)]: "A justice ... may at any time issue 
a warrant" (emphasis added). 
With respect, I must also take exception to the 
Trial Judge's use, in the passage quoted above, of 
the Canadian Bill of Rights [R.S.C., 1985, 
Appendix III]. While there is clearly room for 
debate as to the extent to which the Bill may still 
have a role to play in post—Charter Canada, 6 that 
role surely cannot be one of validating, by inter
pretation, legislation which is otherwise inadequate 
on Charter grounds. 
For constitutional and historical reasons, the 
Bill of Rights employs an interpretative technique 
for the purpose of preserving and protecting the 
rights which it enshrines; it would be a sorry irony 
indeed if it were now to be used to rescue infring
ing legislation from the effect of the entrenchment 
of those same and other rights in the Charter. 
My final comment on the quoted passage of the 
Trial Judge's reasons has to do with her invocation 
of the Court's power to control abuse of the pro
cess, or to add conditions to a warrant. With 
respect, it seems to me that this begs the question. 
If, as the respondents contend, paragraphs (a), (b) 
and (c) of subsection 231.3(3) are exhaustive of all 
the conditions precedent to a reasonable search, an 
application which meets all those conditions 
cannot be an abuse of the process. By the same 
token, if the word "shall" in the opening part of 
subsection 231.3(3) is to be given its normal 
imperative construction, there can be no power in 
the judge to attach conditions to the warrant 
beyond those specifically set out in the statute 
itself. Subsections 231.3(1) and 231.3(4) set out 
the contents of the warrant with considerable 
detail but do not, in any way, suggest any residual 
discretion in the issuing judge to attach other 
terms or conditions. 
In their defence against the attack on the man
datory nature of section 231.3, the respondents 
also rely, as did the Trial Judge, on the obiter 
dictum of the British Columbia Court of Appeal in 
the case of Kourtessis v. M.N.R., [1990] 1 
W.W.R. 97. 
6 See Singh et al. v. Minister of Employment and Immigra
tion, [1985] 1 S.C.R. 177. 
In that case, the Court unanimously dismissed 
on jurisdictional grounds an appeal against a deci
sion at first instance which had upheld the validity 
of section 231.3. 
A majority of the Court went on, however, to 
deal with the substantive grounds of attack. On the 
question which concerns us at the present, Locke 
J.A., after quoting the text of subsections (1),(2), 
and (3) of section 231.3 had this to say [at page 
127]: 
I am of the opinion these three subsections must be read 
together. The crucial function of the judge is to decide whether 
the facts before him are sufficient to warrant an intrusion of 
privacy. This is discretionary in the judge. In order to exercise 
his discretion, the guidelines are set out in subs. (3). If the 
evidence fails the standards of subs. (3), he will not be satisfied 
and will decline to issue the warrant. If the evidence is suffi
cient, the statute says he "shall" issue the warrant. 
It is said that this deprives the judge of a discretion. It does 
not deprive him of the discretion as to whether the warrant 
should issue at all, and as to which he fulfils his balance wheel 
function. It does deprive him of a discretion as to whether the 
warrant in fact issues after he makes the primary essential 
decision. 
One might ask rhetorically, and why not? Having made the 
primary decision, surely the figurative stamping of the piece of 
paper is unimportant. What the mandatory word does is to 
deprive the judge of the discretions argued for in Paroian — 
that it was unnecessary to issue the process because the minis
ter already had enough material. This is not for the court to 
say, by I do not feel that the standards of Hunter v. Southam 
have been defeated. The judge's crucial role has been fulfilled 
and nothing remains except to stamp the piece of paper. It is 
thus true that discretion has been impaired in an administrative 
aspect, but not at all to impair the judge's primary function. It 
is also plain he can always attach conditions to the manner of 
execution of the warrant, and this of his own motion under the 
doctrine of inherent jurisdiction. 
With respect to the last sentence of the quoted 
passage, I can only repeat what I have already 
said: I do not see how a judge acting under an 
imperative statutory provision can invoke an inher
ent jurisdiction to refuse to do precisely that which 
the legislation has declared to be reasonable and 
has commanded him to do. The attachment of 
conditions as to either the issuance or the execu
tion of the warrant is not authorized by the text. 
The earlier part of the quoted passage, if I 
understand it correctly, seems to argue that judi
cial discretion is retained in so far as the determi- 
nation of the conditions set out in paragraphs 
231.3(3)(a), (b) and (c) is concerned, but that 
once the judge is satisfied as to their existence he 
has no further discretion. One might quibble with 
the first of those propositions on linguistic 
grounds; I do not think it proper to characterize 
the formation of an opinion as to the existence of 
reasonable grounds for belief in certain facts as 
being in any way the exercise of a discretion. It is 
of course part of a judicial decision-making func
tion as to which, in any given case, there may be 
differences of view, but that surely does not make 
it a matter of discretion any more than, say, a 
finding of negligence is a matter of discretion. 
The real nub of the matter, however, lies in the 
second proposition. To sustain it, one must argue, 
as counsel for respondents did, not merely that 
Parliament is entitled to set the standards as to 
what is reasonable and in accordance with the 
principles of fundamental justice, but also that, in 
doing so, it may exclude any other consideration as 
being irrelevant to those standards. In my view, 
this cannot be the law. 
Counsel for respondents lays great stress on the 
fact that in the landmark decision of Hunter et al. 
v. Southam Inc. (above), the Court carefully and 
in detail laid down the conditions of a reasonable 
search and seizure pursuant to section 8; nowhere 
amongst them did the Court specifically include a 
condition that the judicial officer issuing the war
rant should retain a discretion to refuse to do so.' 
The question now is to know whether a require
ment of judicial discretion is nonetheless implicit 
in the standards of reasonability set out in South-
am or, even if it is not, whether it forms part of the 
' This fact itself serves to limit the scope to be put on this 
Court's decision in Solvent Petroleum Extraction Inc. v. 
M.N.R. (above). The point now being discussed was not argued 
in that case. Thus, when Desjardins J.A. said (at p. 26) "There 
is no doubt that subsection 231.3(3) meets these minimum 
standards", she was referring to the standards specifically 
enumerated by the Court in Southam from which she had just 
quoted. 
principles of fundamental justice protected by sec
tion 7. In my view, it is both. 
In the first place, it will be recalled that in 
Southam the Court was dealing with a legislative 
provision which, however inadequate on other 
grounds, left a discretion with the officer authoriz
ing the seizure.' 
Secondly, and as previously noted, at the time of 
the Southam decision, all other provisions author
izing searches and seizures in Canada were 
couched in permissive language. Furthermore, as 
the Court was unquestionably aware, historically 
this had always been the case both by statute and 
at common law. 
Finally and most importantly, the Court in 
Southam laid great emphasis on the requirement 
that the officer authorizing the seizure be 
independent and capable of acting judicially in 
balancing the competing interests of the state and 
the citizen. That requirement, as it seems to me, 
given the context in which Southam was decided, 
necessarily implies an ability and a need to exer
cise a judicial discretion in the authorization 
process. 
Accordingly, I conclude that a requirement for a 
residual judicial discretion to refuse to issue a 
search warrant, or to attach conditions to a war
rant when issued, is implicit in the decision in 
Southam as a prerequisite to a reasonable search 
and seizure in accordance with section 8 of the 
Charter. 
Even more important than Southam for the 
purposes of the present discussion, however, is the 
decision of the Supreme Court in Descôteaux et 
al. v. Mierzwinski, [1982] 1 S.C.R. 860. That was 
a pre-Charter case and concerned the issuance of a 
search warrant under the Criminal Code to search 
a lawyer's office. Lamer J., (as he then was), 
8 Subsection 10(3) of the Combines Investigation Act 
[R.S.C. 1970, c. C-23] which provided that an authorization to 
search "may be granted" by a member of the Restrictive Trade 
Practices Commission. 
speaking for a unanimous Court, discussed at 
length the role of judicial discretion in the issuance 
of search warrants. The following passage from his 
reasons is critical [at pages 888-891]: 
Some would say that the justice of the peace has no discre
tion to refuse to issue a search warrant or to impose terms of 
execution once the requirements of form and substance in s. 
443 have been met. They would argue that in s. 443 the word 
"may" means "must" and does not confer any discretion. 
According to this interpretation, the justice of the peace may 
issue a warrant only if he is satisfied that there is reasonable 
ground to believe that one of the things provided for in s. 
443(1) is to be found in the place sought to be searched, but 
must do so as soon as he is so satisfied, and the only condition 
of execution on the premises that he may impose is set out in s. 
444 of the Code: 
444. A warrant issued under section 443 shall be executed by 
day, unless the justice, by the warrant, authorizes execution of 
it by night. 
Others, on the contrary, would say that generally the justice of 
the peace has the discretion to refuse the warrant, so long as 
this discretion is exercised judicially and so long as the decision 
to refuse the warrant is not capricious or arbitrary (Carter, 
R.F., The Law Relating to Search Warrants, 1939, at p. 52; 
Fontana, J.A., The Law of Search Warrants in Canada, 1974, 
at pp. 7 and 51 et seq.; Re Pacific Press Ltd. and The Queen et 
al. (1977), 37 C.C.C. (2d) 487). 
I come down on the side of the discretion, as it allows more 
effective judicial control of the police. Searches are an excep
tion to the oldest and most fundamental principles of the 
common law, and as such the power to search should be strictly 
controlled. It goes without saying that the justice may some
times be in a poor position to assess the need for the search in 
advance. After all, searches, while constituting a means of 
gathering evidence, are also an investigative tool. It will often 
be difficult to determine definitively the probative value of a 
particular thing before the police investigation has been com
pleted. Be that as it may, there are places for which authoriza
tion to search should generally be granted only with reticence 
and, where necessary, with more conditions attached than for 
other places. One does not enter a church in the same way as a 
lion's den, or a warehouse in the same way as a lawyer's office. 
One does not search the premises of a third party who is not 
alleged to have participated in the commission of a crime in the 
same way as those of someone who is the subject of such an 
allegation. (See on this subject Fontana, J.A., The Law of 
Search Warrants in Canada, at p. 174.) 
The justice of the peace, in my view, has the authority, where 
circumstances warrant, to set out execution procedures in the 
search warrant; I would even go so far as to say that he has the 
right to refuse to issue the warrant in special circumstances, 
such as those found in Re Pacific Press Ltd. and The Queen et 
al., supra. 
That case involved a search of a newspaper office for infor
mation gathered by the newspaper staff. Neither the newspaper 
staff nor the newspaper itself were accused of having been 
involved in the commission of an offence. In view of the special 
situation of a newspaper in light of ss. 1(f) and 2 of the 
Canadian Bill of Rights, R.S.C. 1970, Appendix III, Nemet2 
C.J. of the British Columbia Supreme Court quashed the 
search warrant issued by the justice of the peace, concluding a 
follows (at p. 495): 
The issuing of any search warrant is a serious matter, 
especially when its issuance against a newspaper may have, 
as it did, the effect of impeding its publication. To use the 
words of my distinguished predecessor in United Distillers 
Ltd. (1948), 88 C.C.C. 338, [1947] 3 D.L.R. 900, the Justice 
of the Peace `should have reasonable information before him 
to entitle him to judicially decide whether such warrant 
should issue or not'. In my opinion, no such reasonable 
information was before him since there was no material to 
show: 
1. whether a reasonable alternative source of obtaining the 
information was or was not available, and 
2. if available, that reasonable steps had been taken to 
obtain it from that alternative source. 
In my opinion, the bringing of an application for a search 
warrant in these circumstances was an abuse of the process 
of the Court. I, therefore, quash the warrants. 
Re Pacific Press Ltd. involved a search for things provided 
for in para. (b) of s. 443(1), that is, evidence; it goes without 
saying that the same requirements do not apply in the case of 
things provided for in paras. (a) and (c) of s. 443(1). 
It could be advanced that the two conditions set out by 
Nemetz C.J. should be met before a warrant is issued whenever 
a search is sought to be conducted, under 443(1)(b), of prem
ises occupied by an innocent third party which are not alleged 
by the information to be connected in any way with the crime. 
It is not necessary for purposes of this appeal to decide that 
point. It is sufficient to say that in situations such as the one in 
Re Pacific Press Ltd., where the search would interfere with 
rights as fundamental as freedom of the press, and, as in the 
case at bar, a lawyer's client's right to confidentiality, the 
justice of the peace may and should refuse to issue the warrant 
if these two conditions have not been met, lest he exceeds the 
jurisdiction he had ab initio. I would add one qualification to 
these two conditions. The reasonable alternative referred to is 
not an alternative to the method of proof but to the benefits of 
search and seizure of the evidence. As I have already stated, a 
search warrant is not only a means of gathering evidence but 
also an investigative tool. Therefore a determination of what is 
reasonable in each case will take into account the fact that a 
search makes it possible not only to seize evidence but also to 
ascertain that it exits, and even sometimes that the crime was 
in fact committed and by whom. Seizure makes it possible to 
preserve the evidence. 
Moreover, even if the conditions are met, the justice of the 
peace must set out procedures for the execution of the warrant 
that reconcile protection of the interests this right is seeking to 
promote with protection of those the search power is seeking to 
promote, and limit the breach of this fundamental right to what 
is strictly inevitable. This is also true of searches under 
443(1)(a) or (c), as soon as they threaten a fundamental right. 
[Emphasis added.] 
I derive from this passage the proposition not 
only that the attaching of conditions to a search 
warrant is a necessary and essential part of the 
exercise of judicial discretion but, even more 
importantly, that the very existence of such discre
tion is a prerequisite to the reasonableness of the 
search and to our notions of fundamental justice. 
Descôteaux et al. also establishes, in my view, 
that any legislative attempt to exhaustively define 
and circumscribe the limits of what may be a 
reasonable search is doomed to failure. In the 
passage quoted, Lamer J. dealt specifically with 
searches of lawyers' offices and newspaper offices 
and held that in those circumstances the justice 
"may and should refuse to issue the warrant" if 
certain conditions were not met. 
Clearly, however, Lamer J. did not suggest that 
this list of circumstances was limitative. On the 
contrary, he expressly left it open ("in situations 
such as"). In my view, the categories of unreason
able searches are not closed and can never be so. 
Legislating closed categories of unreasonable
ness is not only impossible; it is also likely, through 
the operation of simple human fallibility, to give 
rise to absurdities. The search and seizure provi
sions of the Income Tax Act provide an excellent 
example. In section 488 [as am. by R.S.C., 1985 
(1st Supp.), c. 27, s. 70] of the Criminal Code, 
Parliament has enshrined the old common law rule 
that, without special authorization, no search war
rant shall be executed at night. The reason for this 
must surely be that the law views, and has always 
viewed, night searches as an unreasonable invasion 
of the citizen's privacy unless there are special 
circumstances making such searches permissible. 
Section 488, however, by its very terms, only 
applies to search warrants issued under sections 
487 and 487.1 [as added by R.S.C., 1985 (1st 
Supp.), c. 27, s. 69] of the Criminal Code. There is 
no equivalent limitation on the execution of search 
warrants issued under section 231.3 of the Income 
Tax Act. The absurdity to which the respondents' 
position leads us, therefore, is that, in Parliament's 
view, a night search for terrorist bombs is prima 
fade unreasonable while one for books of account 
is not. Indeed, although the point was not raised 
before us, it is at the least arguable that section 
231.3 is invalid on the sole ground that it allows 
night searches without specific judicial authoriza
tion. 
Parliament, in my opinion, is both legally and 
factually incapable of exhaustively defining unrea
sonable searches. The ultimate protection for the 
citizen against such searches lies in the vigilance of 
the issuing judge and in his power to refuse to 
issue the warrant even where all the conditions 
established by Parliament have been met. For 
Parliament to say and to mean that the judge 
"shall" issue the warrant no matter what the 
circumstances is to sanction unreasonable searches 
and seizures and is contrary to our long-estab
lished principles of fundamental justice. Section 
231.3 is accordingly of no force or effect. 
The foregoing is enough to dispose of the 
present appeal. However, since in my view the 
legislation must be re-written, it would be useful to 
discuss briefly the other grounds argued by the 
appellants. 
The Elimination of the Standard of Probability 
It will be recalled that the standard set by 
subsection 231.3(3) is that of "reasonable grounds 
to believe". The appellants argue that this is not 
good enough. The minimum standard must be 
"reasonable and probable grounds". The appel
lants' focus on the following passage from the 
decision in Southam (above), at page 168: 
In cases like the present, reasonable and probable grounds, 
established upon oath, to believe that an offence has been 
committed and that there is evidence to be found at the place of 
the search, constitutes the minimum standard, consistent with 
s. 8 of the Charter, for authorizing search and seizure. 
By eliminating the word "probable" from the 
legislative standard, it is argued, Parliament has 
suppressed the "more likely than not" standard of 
proof to be applied by the issuing judge. I do not 
agree. 
In the first place, it seems to me that, as a 
matter of simple linguistic construction, the word 
"probable" in the phrase "reasonable and probable 
grounds to believe" adds nothing. In this connec
tion, it is convenient to refer to the standard 
dictionary definition in both official languages. 
The Shorter Oxford English Dictionary gives 
the following modern meaning: 
Probable ... 2. Such as to approve itself to the mind; worthy of 
acceptance or belief; rarely in bad sense, specious, colourable. 
(Now merged in 3.) — 1872. 3. Having an appearance of truth; 
that may reasonably be expected to happen, or to prove true; 
likely 1606. [Emphasis added.] 
Even more interesting is Robert's [Dictionnaire 
alphabétique et analogique de la langue fran-
çaise] indication of an archaic definition for the 
French "probable": 
[TRANSLATION] "Probable" ... 1. Arch. Probable opinion: one 
in which, without excluding the possibility of some other opin
ion there is nothing contrary to reason. — Rel. Probable 
opinion: opinion based on presuasive though not conclusive 
grounds. [Emphasis added.] 
This may very well explain how the word has 
come to be associated historically by lawyers with 
the word "reasonable". Like the second member of 
such other hallowed English legal phrases as "null 
and void", "good and valid", "last will and testa
ment" etc, it does nothing. 
Second, and more significant, this view of the 
matter is confirmed by the judgment in Southam 
itself. In a passage preceding by a few lines the one 
quoted above, Dickson J., (as he then was) speak
ing for the Court said this [at page 167]: 
The common law required evidence on oath which gave "strong 
reason to believe" that stolen goods were concealed in the place 
to be searched before a warrant would issue. Section 443 of the 
Criminal Code authorizes a warrant only where there has been 
information upon oath that there is "reasonable ground to 
believe" that there is evidence of an offence in the place to be 
searched. The American Bill of Rights provides that "no 
Warrants shall issue, but upon probable cause, supported by 
Oath or affirmation .... " The phrasing is slightly different 
but the standard in each of these formulations is identical. 
[Emphasis added.] 
Finally and even if I am wrong in my view as to 
the force to be given to the word "probable" in the 
phrase "reasonable and probable", it is my further 
opinion that a grammatical analysis of subsection 
231.3(3) shows that in fact the evidentiary burden 
of "more likely than not" has been met or 
exceeded. 
Eliminating the unnecessary words for the pur
pose of this analysis, the subsection provides for 
the issuance of a warrant when a judge: 
231.3 (3) 
is satisfied that there are reasonable grounds to believe that: 
(a) an offence ... has been committed; 
(b) a document . is likely to found; and 
(c) the building ... is likely to contain such a document ... 
There can surely be no objection to the standard 
set in paragraphs 231.3(3)(b) and (c) for the word 
"likely" must have the effect of importing the 
standard of probability or "more likely than not." 
With respect to paragraph 231.3(3)(a), the 
standard is set even higher; the requirement is for 
reasonable grounds to believe that an offence has 
been committed. Here, the reasonable belief is tied 
to the actual commission of the offence and not to 
a lower standard of mere probability. 
In the upshot, therefore, I find this ground of 
attack to be without merit. 
The Dilution of the Standard with Respect to the 
Probability of finding Evidence 
The appellants' attack here concentrates very 
narrowly on the wording of paragraph 
231.3(3) (b), which it is convenient to reproduce: 
231.3.. . 
(3) A judge shall issue the warrant referred to in subsection 
(1) where he is satisfied that there are reasonable grounds to 
believe that 
(b) a document or thing that may afford evidence of the 
commission of the offence is likely to be found; and [Empha-
sis added.] 
The argument is that the use of the word "may" 
allows the issuance of a search warrant on showing 
of reasonable grounds to believe in a mere possibil
ity that the thing to be found will afford evidence 
of a crime. The following passage from the judg
ment in Southam is relied on [at page 167]: 
The problem is with the stipulation of a reasonable belief that 
evidence may be uncovered in the search. Here again it is 
useful, in my view, to adopt a purposive approach. The purpose 
of an objective criterion for granting prior authorization to 
conduct a search or seizure is to provide a consistent standard 
for identifying the point at which the interests of the state in 
such intrusions come to prevail over the interests of the 
individual in resisting them. To associate it with an applicant's 
reasonable belief that relevant evidence may be uncovered by 
the search, would be to define the proper standard as the 
possibility of finding evidence. This is a very low standard 
which would validate intrusion on the basis of suspicion, and 
authorize fishing expeditions of considerable latitude. It would 
tip the balance strongly in favour of the state and limit the 
right of the individual to resist, to only the most egregious 
intrusions. I do not believe that this is a proper standard for 
securing the right to be free from unreasonable search and 
seizure. 
The argument seems to me to be quite simply 
unanswerable. The point is an extremely narrow 
one but the Court could not have used clearer 
words to indicate that a belief that evidence may 
be found is not good enough. 
The courts of three provinces have struck down 
subsection 111(1) of the Customs Act [S.C. 1986, 
c. 1] whose English (but not the French) version 
contained a somewhat similar wording. See 
Goguen v. Shannon (1989), 50 C.C.C. (3d) 45 
(N.B.C.A.); Nima v. McInnes, [1989] 2 W.W.R. 
634 (B.C.S.C.); Canada v. Aquarius Computer 
(1989), 2 T.C.T. 4531 (Ont. H.C.). 
While in practice, the line must be very thin 
between a reasonable belief that evidence may be 
found and a reasonable belief that evidence is to be 
found, the Supreme Court has made it very plain 
that only the second meets the requirements of the 
Charter. The text of paragraph 231.3(3)(b) is 
inadequate and therefore inoperative. 
Other Grounds 
In conclusion and for completeness' sake, it is as 
well to mention three grounds argued by appel
lants' counsel upon which we did not call, on the 
respondents. 
The first of such grounds was based on subsec
tion 231.3(5): 
231.3 ... 
(5) Any person who executes a warrant under subsection (1) 
may seize, in addition to the document or thing referred to in 
subsection (1), any other document or thing that he believes on 
reasonable grounds affords evidence of the commission of an 
offence under this Act and shall as soon as practicable bring 
the document or thing before, or make a report in respect 
thereof to, the judge who issued the warrant or, where the 
judge is unable to act, another judge of the same court to be 
dealt with by the judge in accordance with this section. 
Counsel contended that the broad wording of 
this text gave a virtually unfettered discretion to 
the seizing officer and thereby vitiated any war
rant issued under section 231.3. 
We did not agree. 
In the first place, it seemed to us that subsection 
231.3(5) was clearly severable from the rest of the 
section and could not have the effect contended for 
by counsel: at the very most, it could give rise to a 
declaration of invalidity of the subsection and of 
any seizure effected in purported compliance 
therewith. 
Second and even more critical, this Court's 
judgment in Solvent Petroleum, supra, deals 
expressly with the same ground of attack and finds 
that subsection 231.3(5) "meets the test of reason
ableness and therefore of validity". We were not 
persuaded that there was any good reason for us to 
revisit this finding. 
Counsel's final two points dealt with the ques
tion of privilege: solicitor/client and accountant/ 
client. 
With regard to the solicitor/client privilege, the 
Trial Judge said [at pages 297-298]: 
... there seems little doubt that appropriate execution proce
dures were, in fact, followed. The reports made to Mr. Justice 
Strayer pursuant to section 231.3 of the Income Tax Act, 
indicate that a lawyer was present when the search was made 
and that claims for privilege were made pursuant to section 232 
of the Income Tax Act. The documents for which privilege was 
claimed, by the lawyer, were placed in an envelope and turned 
over to Regent Doré as custodian. An application for determi
nation as to whether the documents were properly subject to 
solicitor-client privilege was filed in the Superior Court of 
Quebec. That application was subsequently withdrawn. In this 
regard see the Affidavit and Report to a Judge of Yvon 
Demers, dated October 30, 1986 (paragraphs 3(d) and 4) and 
the Affidavit and Report to a Judge of Gilles Thériault, dated 
June 2, 1987, both on file T-1798-86. In such circumstances it 
cannot seriously be thought that the warrants in question 
should be declared invalid. My understanding of Mr. Justice 
Lamer's statements in Descôteaux is that what is required is 
that the proper procedure is in fact followed. That the proce
dure was not set out on the face of the warrant is not itself 
determinative. 
As far as the claim for accountant/client privi
lege is concerned, a claim based on a number of 
provisions of Quebec law, the Trial Judge said [at 
pages 292-293]: 
Even if I accept that the law of Quebec provides for an 
accountant-client privilege in the context of litigation, I am not 
persuaded that such a rule has been adopted with respect to 
federal income tax litigation. If such a rule were intended to 
apply one would expect to find it expressly so provided in either 
the Canada Evidence Act [R.S.C., 1985, c. C-51 or the Income 
Tax Act. 
and again [at pages 293-294]: 
It is not at all strange that solicitor-client communications 
are privileged in so far as compellable evidence before the 
courts is concerned, while those between an accountant and 
client are not. The purpose of the solicitor-client privilege is to 
ensure free and uninhibited communications between a solicitor 
and his client so that the rendering of effective legal assistance 
can be given. This privilege preserves the basic right of 
individuals to prosecute actions and to prepare defences. As 
Mr. Justice Lamer indicated, in Descôteaux et al. v. Mierzwin-
ski, [1982] 1 S.C.R. 860; (1982), 141 D.L.R. (3d) 590; 70 
C.C.C. (2d) 385; 28 C.R. (3d) 289; 1 C.R.R. 318; 44 N.R. 462 
at page 883 S.C.R., the privilege is recognized because it is 
necessary for the proper administration of justice. I do not 
think there is an overriding policy consideration, of this nature, 
in the case of accountant-client communication. An accountant 
may, as a matter of professional ethics, be required to keep 
communications and other information concerning his or her 
client confidential. But this is not founded upon a need to 
ensure an effective system of the administration of justice. 
We could see nothing to criticize in her treat
ment of either matter and accordingly did not 
require to hear from the respondents. 
Conclusion 
For all the foregoing reasons, I would allow the 
appeals, set aside the judgments of the Trial Divi
sion and substitute for them judgments quashing 
the search warrants and ordering the return of 
everything seized in virtue thereof; I would also 
give a declaration that section 231.3 of the Income 
Tax Act is of no force or effect because it is 
inconsistent with sections 7 and 8 of the Charter. I
