Consent is often a central issue in sexual assault cases in Canada, but each case still turns on its own facts, the surrounding evidence, and the legal rules that apply. The Criminal Code sets out specific rules on consent, capacity, and mistaken belief, and courts apply those rules closely.
If you are dealing with sexual assault allegations, you need to understand exactly how the law defines consent today. Here is a clear overview of the rules, including how intoxication and mistaken belief can affect the analysis.
What Consent Actually Means
In Canadian criminal law, consent means the voluntary agreement of the complainant to engage in the sexual activity in question.
Silence, passivity, or assumptions based on a prior interaction, the relationship, or other surrounding facts are not enough.
Consent is also ongoing. A person can say yes to one thing and no to another. They can also withdraw consent at any time. If they say stop, the consent ends immediately.
When Consent Does Not Exist
The Criminal Code lists situations where there is no consent in law, even if the facts may seem more complicated than a simple verbal “no.”
There is no consent in law where:
• The complainant is incapable of consenting;
• Someone other than the complainant expresses the agreement;
• The accused induces the complainant to engage in the activity by abusing a position of trust, power, or authority;
• The complainant expresses, by words or conduct, a lack of agreement to engage in the activity; or
• The complainant, having previously agreed, expresses by words or conduct a lack of agreement to continue.
The Intoxication Factor
Alcohol and drugs complicate many sexual assault cases. But the law has very specific rules about how intoxication affects consent. We have to look at this from two sides.
1. The Complainant’s Intoxication
A person does not automatically lose the legal capacity to consent just because they have consumed alcohol or drugs. Having a few drinks does not automatically strip away someone’s ability to say yes or no.
But there is a legal line. Severe intoxication can remove the capacity to consent. Courts look at whether the person had the capacity to understand the physical act, its sexual nature, the identity of the partner, and that they could choose to refuse. Memory loss or a later “blackout” does not, by itself, prove incapacity, although it can still be part of the evidence.
2. The Accused’s Intoxication
What if you were the one who was drunk? People often ask if being intoxicated is a defence.
Self-induced intoxication does not create a defence based on a mistaken belief in consent. The Criminal Code also bars that defence where the belief arose from recklessness or wilful blindness.
Mistaken Belief in Consent
This is one of the most misunderstood areas of criminal law.
Sometimes, an accused person will say, “I honestly thought they wanted to.” This is known as the defence of mistaken belief in communicated consent.
It means you believed the person was saying yes through their words or actions. But having an honest belief is not enough to win a trial. The law limits this defence in important ways, including the requirement for reasonable steps.
The “Reasonable Steps” Requirement
To rely on mistaken belief in communicated consent, there must be evidence that reasonable steps were taken, in the circumstances known at the time, to make sure the complainant was consenting.
You cannot just rely on silence. You cannot rely on the fact that they didn’t fight back or didn’t say no. If the evidence does not support reasonable steps, the defence may not be available. The Criminal Code does not allow this defence where there is no evidence that the complainant’s voluntary agreement was affirmatively expressed by words or actively expressed by conduct.
If reasonable steps were not taken, an honest belief in consent will not, on its own, make this defence available.
Why You Need a Defence Lawyer
Sexual assault cases are serious. The consequences of a conviction include jail time, registering as a sex offender, and a permanent criminal record.
If you are being investigated or charged, getting legal advice early can be important. Whether to speak to police depends on the facts and should usually be discussed with counsel first.
A criminal lawyer can review the disclosure, assess the evidence, and advise on the legal issues raised by the case. These cases often involve detailed issues about capacity, intoxication, consent, and the surrounding evidence.
