General Principles

Section 487.01(1) provides a provincial or superior court judge to grant police the general power to "use any device or investigative technique, or procedure" or otherwise do any thing described in the warrant which would constitute an unreasonable search or seizure.

General warrants were added to the Code in 1993, Bill-109 which added s. 487.01 to permit further types of investigative techniques to be used.

Information for general warrant

487.01 (1) A provincial court judge, a judge of a superior court of criminal jurisdiction or a judge as defined in section 552 [definitions - judges] may issue a warrant in writing authorizing a peace officer to, subject to this section, use any device or investigative technique or procedure or do any thing described in the warrant that would, if not authorized, constitute an unreasonable search or seizure in respect of a person or a person’s property if

(a) the judge is satisfied by information on oath in writing that there are reasonable grounds to believe that an offence against this or any other Act of Parliament has been or will be committed and that information concerning the offence will be obtained through the use of the technique, procedure or device or the doing of the thing;

(b) the judge is satisfied that it is in the best interests of the administration of justice to issue the warrant; and

(c) there is no other provision in this or any other Act of Parliament that would provide for a warrant, authorization or order permitting the technique, procedure or device to be used or the thing to be done.

Limitation

(2) Nothing in subsection (1) [general warrants – requirements for authorization] shall be construed as to permit interference with the bodily integrity of any person.

Search or seizure to be reasonable

(3) A warrant issued under subsection (1) [general warrants – requirements for authorization] shall contain such terms and conditions as the judge considers advisable to ensure that any search or seizure authorized by the warrant is reasonable in the circumstances.

A general warrant authorizes the use of "any device or investigative technique or procedure or do anything described in the warrant that would, if not authorized, constitute an unreasonable search or seizure." The pre-conditions require that:

1. There are reasonable grounds to believe an offence has been or will be committed and information concerning the offence will be obtained through the use of the technique, procedure or device or doing of the thing.
2. It is in the best interests of the administration of justice to issue the warrant.
3. There is no other provision in the Criminal Code or any other Act of Parliament that would provide for the warrant, authorization or order permitting the technique to be done.

Warrants under s. 487.01 are unique from all warrants. They do not have any special or procedural limitations. They authorize any police activity that would intrude on s. 8 rights.

The phrase "information concerning the offence" should be "given the broadest possible interpretation" and "includes whatever is necessary to get at the truth and properly and fairly dispose of the case."

"No Other Provision"

Interpreting the meaning of s. 487.01(1)(c) should focus "on the particular investigative technique or procedure that the police seek to utilize and whether it can properly be authorized by another provision in the Code or any other federal statute". The provision should be broad in meaning to prevent presumptive use of these warrants. They should be used "sparingly."

The general warrant must not be used to "circumvent other authorization provisions that are available but contain more onerous pre-conditions."

A "covert entry and search" are governed by 487.01.

A general warrant can authorize multiple "covert entries and searches on private property."

A general warrant may be granted to mimic a theft to seize the accused luggage which contained drugs. In circumstances where persons' safety may be at risk, it is necessary for those risks to be addressed in the ITO.

Where a Part VI wiretap warrant is available, there can be no general warrant.

Notice Requirements

487.01
[omitted (1), (2), (3), (4) and (5)]

Notice after covert entry

(5.1) A warrant issued under subsection (1) [general warrants – requirements for authorization] that authorizes a peace officer to enter and search a place covertly shall require, as part of the terms and conditions referred to in subsection (3) [general warrants – terms and conditions], that notice of the entry and search be given within any time after the execution of the warrant that the judge considers reasonable in the circumstances.

Extension of period for giving notice

(5.2) Where the judge who issues a warrant under subsection (1) [general warrants – requirements for authorization] or any other judge having jurisdiction to issue such a warrant is, on the basis of an affidavit submitted in support of an application to vary the period within which the notice referred to in subsection (5.1) [general warrants – notice after covert entry] is to be given, is satisfied that the interests of justice warrant the granting of the application, the judge may grant an extension, or a subsequent extension, of the period, but no extension may exceed three years.
[omitted (6) and (7)]
1993, c. 40, s. 15; 1997, c. 18, s. 42, c. 23, s. 13; 2019, c. 25, s. 192; 2022, c. 17, s. 17.

A failure of the authorizing justice to require police to give notice of a covert entry and surveillance may render the warrant invalid.

Different Territorial Divisions

The rules concerning territorial divisions for s. 487 warrants equally apply to general warrants:

487.01
[omitted (1), (2), (3), (4), (5), (5.1) and (5.2)]

(6) A warrant issued under subsection (1) [general warrants – requirements for authorization] may be executed at any place in Canada. Any peace officer who executes the warrant must have authority to act as a peace officer in the place where it is executed.

Video Surveillance

Anticipatory Warrants

An anticipatory warrants are those "that may only be executed upon the fulfillment of certain pre-conditions."

Anticipatory warrants can only be authorized as a general warrant under s. 487.01. An anticipatory warrant to seized text messages from an telephone service provider has some support to require a general warrant as opposed to a wiretap warrant.

Other Circumstances

A 487.01 warrant may authorize an "covert" search. This includes "covert" entries into a residence.

It may also authorize the use of "vision enhancement equipment", including binoculars, night vision devices, video cameras, etc.

Computer Searches

Where a search warrant is executed for a computer search and evidence of an unrelated offence is discovered, the proper procedure is to apply for a search warrant and not a general warrant.
