"Consent for the purposes of sexual assault is defined in s. 273.1(1) ( of the Criminal Code) as “the voluntary agreement of the complainant to engage in the sexual activity in question”. This suggests that the consent of the complainant must be specifically directed to each and every sexual act, negating the argument that broad advance consent is what Parliament had in mind. As discussed below, this Court has also interpreted this provision as requiring the complainant to consent to the activity “at the time it occur[s]"."
