Sexual assault in Canada is prosecuted under the Criminal Code in three graduated levels — sexual assault, sexual assault with a weapon or causing bodily harm, and aggravated sexual assault — each carrying increasing maximum penalties. The Crown, not the complainant, controls whether the case proceeds, and a complainant cannot unilaterally withdraw the charge. Consent has a specific legal definition that excludes, among other things, consent obtained through fear, abuse of trust, or while a person lacks capacity. A publication ban protecting the complainant's identity is commonly available on request. Given the stakes and procedural complexity, getting a lawyer involved immediately — before any statement to police — is critical.
- Sexual assault is prosecuted at three graduated levels under the Criminal Code — sexual assault, sexual assault with a weapon or causing bodily harm, and aggravated sexual assault — each with higher maximum penalties.
- The Crown controls the prosecution, not the complainant — a complainant cannot simply decide to drop the charge once it is laid.
- Consent has a specific legal definition under the Criminal Code, and certain circumstances — including abuse of a position of trust or incapacity — can mean no valid consent existed in law even without physical force.
- A publication ban protecting the complainant's identity is commonly ordered on request, which affects how the case can be discussed publicly.
- These charges carry no limitation period — a charge can be laid years or even decades after the alleged conduct.
- Saying nothing to police beyond basic identification, and getting a lawyer involved immediately, is more important here than in almost any other type of charge.
The Short Answer
Sexual assault charges in Canada are prosecuted entirely by the Crown under three graduated levels of the Criminal Code, with the complainant playing an important but ultimately non-controlling role in how the case proceeds. Consent has a specific legal definition that goes beyond the absence of physical resistance, there is no limitation period on when a charge can be laid, and the procedural and evidentiary landscape is genuinely different from other criminal matters. Early, specific legal advice is critical.
The Three Levels of the Offence
The Criminal Code structures sexual assault into three levels of escalating seriousness:
- Sexual assault — the base offence, covering non-consensual sexual contact.
- Sexual assault with a weapon, threats to a third party, or causing bodily harm — a mid-level offence where the conduct involved a weapon, a threat extending to someone else, or resulted in bodily harm.
- Aggravated sexual assault — reserved for the most serious cases, involving wounding, maiming, disfiguring, or endangering the complainant's life.
Each level carries a correspondingly higher maximum penalty. Which level is charged, and how the Crown elects to proceed, depends heavily on the specific allegations — see our general guide on summary vs. indictable offences in Ontario for how that election process works more broadly.
How the Law Defines Consent
Consent must be a voluntary agreement to engage in the specific sexual activity in question, given by a person with the capacity to consent at the time. The Criminal Code specifically identifies circumstances where the law treats no valid consent as having been given, including:
- Where agreement is expressed by someone other than the complainant
- Where the complainant was incapable of consenting, including due to intoxication
- Where consent results from an abuse of a position of trust, power, or authority
- Where the complainant expressed, by words or conduct, a lack of agreement, or subsequently expressed a lack of agreement to continue
Consent is also not a one-time, all-or-nothing event — a person can validly consent to one act and not another, or withdraw consent partway through an encounter, and continuing after that point can support a charge regardless of what was agreed to earlier.
Why the Complainant Cannot “Drop” the Charge
A common misunderstanding is that a complainant who no longer wishes to pursue a charge can simply have it dropped. In reality, once police lay a charge, the decision over whether to proceed, resolve, or withdraw it rests with the Crown prosecutor, not the complainant. The complainant's current position is a factor the Crown may consider, but it is only one input into a decision the Crown ultimately controls — a dynamic explained in more general terms in our guide on how assault charges get dropped or withdrawn in Ontario.
Publication Bans
A publication ban protecting a complainant's identity is commonly available on request in sexual offence proceedings, and once granted, it restricts what can be published or broadcast about the complainant's identity — a tool both complainants and the broader proceeding can be affected by. Our dedicated guide on publication bans in Ontario criminal court explains how these orders work and what they do and do not cover.
How the Process Unfolds
After a charge is laid, the case follows the general criminal court process — a first appearance, Crown disclosure of the evidence against you, and either resolution discussions or a path toward trial. See our overviews of your first criminal court appearance in Toronto and Crown disclosure obligations in Ontario for how those stages generally work. Sexual offence cases often involve particularly sensitive disclosure material and can raise distinct evidentiary issues, including rules around the complainant's prior sexual history and, in some cases, third-party records.
Common Defences
- Consent — where the defence is that the complainant validly consented to the activity in question.
- Honest but mistaken belief in consent — a narrower defence requiring reasonable steps to have been taken to ascertain consent.
- Identification — challenging whether the accused was correctly identified as the person responsible.
- Charter and procedural challenges — including how evidence was gathered or how disclosure obligations were met.
What to Do If You Are Charged
Provide only basic identifying information to police and say nothing further about the allegation — anything said, including an attempt to explain, can be used against you and is extremely difficult to retract later. If you have been arrested, understanding how bail works in Ontario is an immediate next step, and if release conditions later need to change, see our guide on varying bail conditions in Ontario.

Frequently Asked Questions
Sexual assault (the base offence), sexual assault with a weapon, threats to a third party, or causing bodily harm (a mid-level offence), and aggravated sexual assault (reserved for cases involving wounding, maiming, disfiguring, or endangering life). Each level carries progressively higher maximum penalties.
No, not unilaterally. Once police lay a charge, the decision to proceed, resolve, or withdraw it rests with the Crown prosecutor, not the complainant. A complainant's wishes can be a factor the Crown considers, but they do not control the outcome the way popular belief often assumes.
Consent must be a voluntary agreement to engage in the specific sexual activity in question, given by someone with the capacity to consent. The Criminal Code specifically lists circumstances where no consent is obtained in law, including where consent is expressed by someone other than the complainant, where the complainant is incapable of consenting, where consent results from an abuse of a position of trust or authority, or where the complainant later expresses a lack of agreement.
No. Unlike many other offences, there is no limitation period for sexual assault charges in Canada — a charge can be laid based on conduct alleged to have occurred years or even decades earlier.
Charges and court proceedings are generally part of the public record, though a publication ban can be ordered — most commonly to protect a complainant's identity — which can also limit what can be reported about the proceeding more broadly in some circumstances.
Provide only basic identifying information and say nothing else about the allegation until you have spoken with a lawyer. Anything said to police, even in an attempt to explain or clarify, can be used in the prosecution and is very difficult to walk back later.
A pending charge can appear on certain types of background and vulnerable-sector checks even before trial, which can have immediate consequences for employment or volunteering. See our guide on how a criminal charge shows up on a background check in Ontario.
It can, often significantly and immediately, particularly in regulated professions or roles involving vulnerable people. See our guide on how a criminal charge can affect your job in Ontario for how this plays out.
