Consent is the central legal concept in every sexual assault case in Canada. How it is defined in the Criminal Code, when it is legally unavailable regardless of apparent agreement, and how it operates as both a Crown element and a defence consideration are questions that determine outcomes in Ontario courts every day. NR Lawyers has litigated consent issues in sexual assault cases at every level of the Ontario court system for over 30 years.
Consent in the context of sexual assault is defined in Section 273.1 of the Criminal Code as the voluntary agreement of the complainant to engage in the sexual activity in question. The agreement must be voluntary, it must be to the specific sexual activity in question, and it must exist at the time of the activity. Past consent does not authorize future conduct. Consent can be withdrawn at any point, and once withdrawn it must be respected immediately.
Section 273.1(2) of the Criminal Code specifies circumstances in which no consent is obtained regardless of what appears to occur. These include where the complainant is incapable of consenting due to unconsciousness or severe intoxication, where consent is obtained through abuse of a position of trust or authority, where a third party purports to consent on behalf of the complainant, and where the complainant expresses by words or conduct a lack of agreement to engage or continue.
The Supreme Court of Canada has confirmed that a person cannot consent in advance to sexual activity that will occur while they are unconscious. Consent must be present and communicable at the time of the activity. This position is now clearly established in Canadian law and has significant implications for defence strategy in cases where intoxication or unconsciousness is alleged.
An honest but mistaken belief in consent is a recognized defence in Canadian sexual assault law. The Crown bears the burden of proving beyond a reasonable doubt that the accused did not hold such a belief. However, the defence is subject to restrictions under Section 273.2. The accused cannot rely on a belief that arose from self-induced intoxication, recklessness, or wilful blindness. The accused must have taken reasonable steps in the circumstances to ascertain whether the complainant was consenting.
Consent law shapes every aspect of sexual assault defence strategy in Ontario. The disclosure review focuses on evidence that supports the accused’s honest belief in consent. The cross-examination strategy targets the specific points where the complainant’s account of their non-consent is inconsistent, implausible, or contradicted by their own prior communications. Pre-trial applications under Section 276 may be brought where evidence of the complainant’s prior sexual history is relevant to the consent issue.
Intoxication affects consent in two ways. First, a complainant who is incapacitated by intoxication is legally incapable of consenting. Second, the accused’s own intoxication does not constitute a defence to sexual assault. The question of what degree of intoxication renders a complainant legally incapable is a factual determination made by the court based on the evidence presented at trial.
Consent law in Canada is technically precise, and small factual differences can determine whether the consent defence is available and whether the Crown can prove the absence of consent beyond a reasonable doubt. NR Lawyers has 30 years of specific experience in this area and publishes detailed legal analysis through its sexual assault newsletters to remain current with every development in Ontario and Canadian courts.

No. Silence is not consent under Canadian law. The Criminal Code requires a voluntary agreement to the specific sexual activity. The absence of a verbal objection or physical resistance does not constitute consent.
A person who is intoxicated can still consent to sexual activity provided they retain the capacity to form and communicate a voluntary agreement. The legal question is whether the degree of intoxication has reached a point where the complainant is no longer capable of consenting, which is a factual determination based on the specific circumstances and the evidence.
The rape shield provisions in Sections 276 and 277 restrict the use of evidence about the complainant’s prior sexual history and reputation. Such evidence cannot be introduced without a specific court application demonstrating that the evidence meets the legal test. NR Lawyers regularly publishes analysis of developments in this area through its legal newsletters.
Where both the accused and the complainant were intoxicated, the legal analysis focuses on whether the complainant was incapacitated to a degree that made consent legally unavailable, and whether the accused held an honest belief in consent based on reasonable steps taken in the circumstances. The accused’s intoxication does not reduce their legal responsibility for taking reasonable steps to ascertain consent.
The reasonable steps requirement asks what the accused actually did to ascertain consent and whether those steps were reasonable given everything they knew at the time. Courts in Ontario assess this objectively. What counts as reasonable varies based on the relationship between the parties, the circumstances of the encounter, and any signals the complainant communicated.
No. Canadian law does not permit a defence based on prior consent to sexual activity during unconsciousness or sleep. Consent must exist and be communicable at the time of the sexual activity. A consent defence based on prior agreement to activity during sleep is not available under Canadian law following Supreme Court confirmation of this position.
