Overview

Offences relating to unauthorized use of a computer are found in Part IX of the Criminal Code relating to "Offences Against Rights of Property".

Pleadings

Offence Section	Offence Type	Crown Election	Defence Election s. 536(2)	Preliminary Inquiry
s. 342.1 [unauthorized use of computer] s. 342.2 [possession of device to obtain unauthorized use of computer system or to commit mischief]	Hybrid Offence(s)		(* only if Crown proceeds by Indictment)	(under 14 years max)

Offences under s. 342.1 [unauthorized use of computer] and 342.2 [possession of device to obtain unauthorized use of computer system or to commit mischief] are hybrid with a Crown election. If prosecuted by indictment, there is a Defence election of Court under s. 536(2) to trial by provincial court, superior court judge-alone or superior court judge-and-jury.

Release

Offence(s)	Appearance Notice by Peace Officer s. 497	Summons by Judge or Justice s. 508(1), 512(1), or 788	Release by Peace Officer on Undertaking s. 498, 499, and 501	Release By a Judge or Justice on a Release Order s. 515 to 519	Direct to Attend for Fingerprints, etc. Identification of Criminals Act s. 2 ID Crim. Act
s. 342.1 [unauthorized use of computer] or 342.2 [possession of device to obtain unauthorized use of computer system or to commit mischief]

When charged under s. 342.1 [unauthorized use of computer] or 342.2 [possession of device to obtain unauthorized use of computer system or to commit mischief] , the accused can be given an appearance notice without arrest under s. 497 or a summons. If arrested, he can be released by the arresting officer under s. 498 or 499 on an undertaking with or without conditions. He can also be released by a justice under s. 515.

Reverse Onus Bail

If police decide to bring the accused before a Justice pursuant to s. 503, there will be a presumption against bail (i.e. a reverse onus) if the offence, prosecuted by indictment, was committed:

• while at large under s. 515 [bail release], 679 or 680 [release pending appeal or review of appeal] (s. 515(6)(a)(i));
• "for the benefit of, at the direction of, or in association" with a criminal organization (s. 515(6)(a)(ii));
• where the offence involved a weapon, being a firearm, cross-bow, prohibited weapon restricted weapon, prohibited device, ammunition, prohibited ammunition or explosive substance, while the accused was subject to a prohibition order preventing possession of these items (s. 515(6)(a)(viii)); or
• where the accused is not "ordinarily a resident in Canada" (s. 515(6)(b)).

And, regardless of Crown election, if the offence alleged was one:

• where the offence was an allegation of violence against an "intimate partner" and the accused had been previously convicted of an offence of violence against an "intimate partner" (s. 515(6)(b.1));
• where the offence alleged is a breach under s. 145(2) to (5) while (s. 515(6)(c));
• where the offence committed (or conspired to commit) was an offence under s. 5 to 7 of the CDSA that is punishable by life imprisonment (s. 515(6)(d));

Fingerprints and Photos

A peace officer who charges a person under s. 342.1 [unauthorized use of computer] or
342.2 [possession of device to obtain unauthorized use of computer system or to commit mischief] of the Code can require that person to attend for the taking of fingerprints, photographs or other similar recordings that are used to identify them under the Identification of Criminals Act.

Publication Bans

For all criminal or regulatory prosecutions, there is a discretionary general publication ban available on application of the Crown, victim or witness to prohibit the publishing of "any information that could identify the victim or witness" under s. 486.5(1) where it is "necessary" for the "proper administration of justice". Other available publication bans include prohibitions for publishing evidence or other information arising from a bail hearing (s. 517), preliminary inquiry (s. 539) or jury trial (s. 648). There is a mandatory publication ban in all youth prosecutions on information tending to identify young accused under s. 110 of the YCJA or young victims under s. 111 of the YCJA.

Proof of the Offence

Proving fraudulently obtaining of computer services under s. 342.1(1)(a) should include: ☐ identity of accused as culprit ☐ date and time of the incident ☐ jurisdiction (incl. region and province) ☐ the culprit obtained, "directly or indirectly, any computer service"; ☐ the service was prohibited to the culprit; ☐ A reasonable person in the same circumstances as the accused would have agreed that this was a dishonest activity and ☐ the culprit did the prohibited act "fraudulently and without colour of right".

Interpretation of the Offence

The crown must prove that the accused had the knowledge that the act and intended use was wrong.

The Crown must also prove that the accused obtained the services "knowingly and voluntarily". This requires that there was an "intent to commit the prohibited act" and that the act was known to be prohibited "with regard to the planned purposes of this use".

The unauthorized access to policing systems such as CPIC may constitute fraudulent access to a computer system contrary to s. 342.1(1)(a). There is suggestion that the act of engaging in "spear phishing" to gain access to email accounts is also a violation of s. 342.1.

Forfeiture of Proceeds of Crime (s. 462.37(1) or (2.01))	any	Where there is a finding of guilt for an indictable offence under the Code or the CDSA in which property is "proceeds of crime" and offence was "committed in relation to that property", the property shall be forfeited to His Majesty the King on application of the Crown.

However, under s. 491(2), if the lawful owner "was not a party to the offence" and the judge has "no reasonable grounds to believe that the thing would or might be used in the commission of an offence", then it should be returned to the lawful owner.
