There are several key defences available against assault charges, including self-defence, defence of property, accidental actions, consent for the use of force, unintentional reflex actions, the trivial nature of the offence, agreeing to counselling and apologizing, agreeing to a peace bond, and seeking a pre-trial resolution. Self-defence is justified under s. 34 of the Criminal Code when reasonable force is used to protect oneself or others. Defence of property is applicable when property is threatened. Accidental actions require demonstrating that the outcome was unintended. Consent involves situations where the use of force was mutually agreed upon, such as in consensual fights. Reflex actions that are involuntary and do not demonstrate intent can negate the mens rea for assault. The principle of 'de minimis non curat lex' may apply if the offence is considered too trivial. Counseling, apologies, peace bonds, and pre-trial resolutions can also be paths towards mitigating or resolving charges, depending on the circumstances of the case.
