Canadian Criminal Law/Defences/Accident and Mistake

Accident edit

An accident is a "mishap or untoward event not expected or designed", or "unforeseen contingency or occurrence"[1] Its meaning varies depending on the type of charge. Where it is a specific intent offence, an accident relates to a denial of voluntariness of the act or denial of intention to cause the outcome. General intent offence claims the act was unexpected or chance that was not foreseeable. [2]

The effect in law is that the mens rea is not present. This is distinctive from mistake which occurs in “the realm of perception”.[3]

Once the accused establishes there is an "air of reality" to the defence, the crown must disprove the availability of the defence. [4]

Reflex edit

It is permissible to argue that the action of accused was not voluntary as it was a reflexive act.[1]
