Offence Specific Defence
Self Defence or Defence of Another
An individual has the right to use force to protect themselves if necessary. If person B assaults or attempts to assault person A, person A is legally entitled to use force (i.e., commit an assault) against person B in self defence. Person B cannot use any more force than is necessary to stop person A’s assault. An individual may also use the force necessary to defend an attack on another person. This legal defence is outlined in section 34(1) of the Criminal Code.
Defence of Property
An individual has the right to use force to protect their property or to remove someone from their property. The force used must be reasonable and only what is necessary to expel the person from the property. If a person does not have a legal right to the property, they may not use force to remove another person. This legal defence is outlined in section 35(1) of the Criminal Code.
To gain a conviction for assault – choking, the Crown must prove that the accused assaulted the complainant and strangled, choked or suffocated the complainant in the process. If the complainant was not strangled, choked or suffocated the accused cannot be convicted of assault – choking.
For example, person A and person B are in an intimate relationship. They get into an argument in a public parking lot and person B grabs person A by the front of the coat. From behind, witnesses believe they have seen person B grab person A by the throat. Witnesses call police and person B is charged with assault – choking. Person B is guilty of simple assault for grabbing person A’s coat, but is not guilty of assault – choking.
