Canadian Criminal Law/Offences/Possession of a Weapon for a Dangerous Purpose

Proof of Offence
Including the elements of time and date, jurisdiction, and identity, the crown must prove:
 * 1) that the object was in the possession of the accused,
 * 2) that the object was a weapon as defined in the Criminal Code, and
 * 3) that the purpose for which the respondent had possession was one which was dangerous to the public peace
 * 4) that there was a danger to the public peace
 * 5) continuity of the object
 * 6) the object was filed as an exhibit

Interpretation
The actus reus of the offence is established through possession.

Much of s. 88 consideration is upon the purpose for which the accused possessed the weapon.

Possessing a weapon in a reckless manner is not sufficient for proof of s.88.

Purpose
Proof of the purpose for possessing the weapon may be established by the manner in which the weapon is used, circumstances and statements surrounding its use and the rational inferences to be drawn from the facts

A person's initial intent in possessing a weapon "does not necessarily remain constant and may change to a dangerous intent even though the initial purpose in taking possession was not a dangerous one." It has been suggested that the lawful possession of a weapon does not suddenly become unlawful by virtue of the possessor acting out in sudden anger with the weapon.

It is not sufficient to simply establish that "what was done was in fact dangerous to the public peace". There must be an intent for that purpose.

Self-Defence
Self-defence can be a limited defence to this charge. However, self-defence will only apply where the attack is imminent and inescapable.

Kiennapple
Where the evidence is substantially the same for proving the elements of possession for a dangerous purpose and assault with a weapon, convictions on both are precluded.
