Aggravated sexual assault is defined in section 273 of the Criminal Code of Canada. It is a sexual assault committed in circumstances where the accused wounds, maims, disfigures, or endangers the life of the complainant.
To establish aggravated sexual assault, the Crown must prove all of the following beyond a reasonable doubt:
Unlike sexual assault under section 271, which is a hybrid offence, aggravated sexual assault is a straight indictable offence. The Crown cannot proceed summarily. Because aggravated sexual assault is a straight indictable offence, the accused has full election rights and may choose trial in the Ontario Court of Justice before a judge alone, in the Superior Court of Justice before a judge alone, or in the Superior Court before a judge and jury. The offence carries the most serious penalties available in Canadian sexual offence law.
The four aggravating circumstances under section 273 have specific legal meanings:
Courts have found the aggravated element established in cases involving deep lacerations, broken bones, stabbing, strangulation, sustained beating, permanent disfigurement, and conduct that placed the complainant's life at serious risk.
The Supreme Court of Canada has held that an HIV-positive person who does not disclose their status to a sexual partner can be convicted of aggravated sexual assault where there was a realistic possibility of HIV transmission. The legal framework established in R. v. Mabior (2012) continues to govern many HIV non-disclosure cases, although this area of law remains subject to ongoing legal and policy developments. Outside those circumstances, non-disclosure can support an aggravated sexual assault charge on the theory that the complainant's consent was vitiated by fraud and that their life was endangered. The Crown must establish that the alleged non-disclosure amounted to fraud capable of vitiating consent under Canadian criminal law. These cases are highly technical and require expert medical evidence on viral load, transmission risk, and the specific circumstances of the alleged contact.

In aggravated sexual assault cases, early retention of a criminal defence lawyer can be crucial. It can help not only avoid hurting your case during questioning but also pursue your release on bail, minimizing the disruption the charges can have on your life.
In most cases of aggravated sexual assault, the police may arrest you and keep you in custody due to the seriousness of the charges. Unlike other offences where the onus to demonstrate why you should be kept in custody lies with the Crown, in aggravated sexual assault cases, you may be required to show why your detention is not justified. Engaging an experienced sexual assault lawyer early can help get to the bail hearing well prepared with a solid release plan.
Understanding how aggravated sexual assault differs from the other levels of sexual offence is essential to understanding what you are facing.
| Offence | Criminal Code | Key Element | Maximum Sentence |
| Sexual Assault | s. 271 | Non-consensual sexual touching | 10 years on indictment (14 years if the complainant is under 16) |
| Sexual Assault with a Weapon, Threats, or Causing Bodily Harm | s. 272 | A weapon was used, threats were made, bodily harm caused, or choking/strangulation occurred | 14 years (life if complainant under 16) |
| Aggravated Sexual Assault | s. 273 | The complainant was wounded, maimed, disfigured, or had their life endangered | Life imprisonment |
The Crown's choice of section reflects the evidence available and the seriousness of the alleged conduct. Where the facts could support a charge under either section 272 or section 273, the defence may be able to negotiate with the Crown to proceed on the lesser charge, depending on the strength of the evidence on the aggravating element.
| Circumstances | Minimum Sentence | Maximum Sentence |
| Aggravated sexual assault, no firearm, complainant 16 or older | None | Life imprisonment |
| First offence: a restricted or prohibited firearm was used, or a firearm was used in connection with a criminal organization | 5 years | Life imprisonment |
| Second or subsequent offence, restricted or prohibited firearm | 7 years | Life imprisonment |
| Any firearm other than a restricted or prohibited firearm is used, the offence is not connected to a criminal organization, and the complainant is aged 16 or older | 4 years | Life imprisonment |
| Any firearm other than a restricted or prohibited firearm used by the complainant under 16 years old | 5 years | Life imprisonment |
| Complainant under 16; no firearm used | 5 years | Life imprisonment |
A conviction triggers several mandatory consequences in addition to imprisonment:
Serious criminal consequences under section 36(1) of the Immigration and Refugee Protection Act
You have the right to silence under section 7 of the Charter of Rights and Freedoms and the right to retain counsel without delay under section 10(b). Exercise both. Do not provide a statement to the police. Do not try to explain your side. Do not contact the complainant. Do not contact anyone who may be a witness. Anything you say to the police can be used against you at trial. Silence cannot.
In many aggravated sexual assault cases, the accused is held for a bail hearing shortly after arrest. Depending on the circumstances, a reverse onus may apply, meaning the accused must demonstrate why release is justified.
The Crown frequently seeks strict release conditions, including no-contact orders, communication restrictions, and sureties. Early legal representation can be critical to securing a workable release plan.
Once charges are laid, you are entitled to disclosure of the evidence the Crown intends to rely on. In aggravated sexual assault cases, this may include police notes, witness statements, medical records, forensic and DNA evidence, expert reports, and digital evidence.
We carefully review the disclosure for inconsistencies, investigative deficiencies, Charter issues, and other weaknesses that may support the defence.
Because aggravated sexual assault carries a maximum sentence of life imprisonment, the accused has the right to elect trial in the Ontario Court of Justice before a judge alone, in the Superior Court of Justice before a judge alone, or in the Superior Court before a judge and jury.
Unlike many criminal offences, aggravated sexual assault remains eligible for a preliminary inquiry. This procedure allows the defence to test the Crown's evidence before trial and may provide strategic advantages in preparing the case.
Following the Supreme Court of Canada's decision in R. v. Ndhlovu and the enactment of Bill S-12, SOIRA registration is no longer automatic in every case.
For aggravated sexual assault, registration is mandatory where:
In other cases, there is a presumption that a SOIRA order will be made, although the court retains limited discretion not to impose registration in appropriate circumstances.
Where imposed, a SOIRA order is typically for life and requires ongoing reporting obligations. Failure to comply with those obligations is a separate criminal offence.
A conviction for aggravated sexual assault triggers a mandatory DNA collection order under section 487.051 of the Criminal Code. The sample is added to the National DNA Data Bank and may be compared against DNA profiles associated with designated criminal investigations in accordance with Canadian law.
Where the complainant was under 16, the court may impose a prohibition order under section 161 of the Criminal Code. Such orders can restrict access to places where children are commonly present, limit certain employment or volunteer activities, and impose restrictions on internet use. These conditions may remain in effect long after the sentence has been completed.
For non-citizens, an aggravated sexual assault conviction can have severe immigration consequences. Because the offence carries a maximum sentence of life imprisonment, it falls within the serious criminality provisions of the Immigration and Refugee Protection Act. Depending on the circumstances, permanent residents may face removal proceedings, while temporary residents and citizenship applicants may become inadmissible.
Every aggravated sexual assault case turns on its specific facts. The defences below are commonly available in Ontario and are the starting point for our work on every file.
To secure a conviction under section 273, the Crown must prove both the underlying sexual assault and the aggravating element of wounding, maiming, disfigurement, or endangerment of life. Even where the Crown establishes the underlying sexual activity, it may fail to prove that the alleged injuries meet the legal threshold required for aggravated sexual assault. Medical and expert evidence often play an important role in determining the nature, cause, and severity of the alleged injuries. Where the aggravating element cannot be proven beyond a reasonable doubt, the charge may be reduced to sexual assault under section 271 or sexual assault with a weapon or causing bodily harm under section 272.
Where the case turns on whether the sexual activity was consensual, the same principles that apply in other sexual assault cases remain relevant. Consent 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 Supreme Court of Canada confirmed in R. v. Ewanchuk that silence, passivity, or a failure to resist does not constitute consent.
The defence of honest but mistaken belief in communicated consent under section 273.2 is limited and requires evidence that the accused took reasonable steps to ascertain consent. It is not available where the accused was reckless, wilfully blind, or self-indulgent, intoxicated.
The Crown's case often depends heavily on the complainant's evidence. Inconsistencies between statements, memory issues, and reliability concerns may become important issues at trial. Credibility and reliability are separate legal concepts and can be challenged independently through cross-examination and other evidence.
In cases where the complainant did not know the accused, or where the identification is based on limited observation, identity is a live issue. DNA evidence, alibi, surveillance footage, and expert evidence on the reliability of eyewitness memory can all be relevant.
Where the police breached the accused's rights under the Charter during the investigation, unlawful search, failure to advise of the right to counsel, improper interrogation, evidence obtained as a result may be excluded under section 24(2). In aggravated sexual assault cases, the exclusion of a statement by the accused or critical forensic evidence can lead to a stay or withdrawal of the charge.
The framework set out in R. v. Jordan (2016) imposes a presumptive ceiling of 30 months in the Superior Court of Justice from the date of charge to the actual or anticipated end of trial. Aggravated sexual assault cases, with their complexity, expert evidence, and frequent need for preliminary inquiries, often push against these ceilings. A successful Jordan application results in a stay of proceedings. We track Jordan delay from the date charges are laid through to the actual or anticipated end of trial
Aggravated sexual assault allegations often involve complex medical evidence, forensic reports, DNA analysis, digital communications, and competing accounts of what occurred. Our defence begins with a detailed review of disclosure to identify weaknesses in the Crown's case. Our sexual assault lawyer assesses whether the alleged injuries meet the legal threshold required under Section 273, reviews medical records and expert opinions, examines issues of consent and identification, and investigates potential Charter violations. Where appropriate, we retain independent experts, challenge unreliable evidence, and seek to exclude improperly obtained evidence. Our objective is to identify inconsistencies in the Crown's case, bring it to a rigorous test, and assert your right to the presumption of innocence.

According to the Criminal Code of Canada, assault generally involves the intentional application of force to another person without their consent. In the case of sexual assault, this application of force happens in circumstances of a sexual nature. Generally, non-aggravated sexual assault does not involve serious bodily harm to the complainant. In contrast, aggravated sexual assault as defined in Section 273 is a more serious offence involving serious bodily harm, for example, wounds, maiming, or disfigurement, or other harm that endangers the life of the complainant.
In Canada, the maximum penalty for aggravated sexual assault is life imprisonment. In addition, Section 273 of the Criminal Code defines mandatory minimum sentences for aggravated sexual assault cases involving restricted, prohibited, or other firearms, including firearms used in connection with a criminal organization, or cases where the complainant was under 16 years of age.
Yes, in some cases, an aggravated sexual assault conviction under Section 273 may carry a minimum punishment of imprisonment.
The term of a mandatory minimum imprisonment for aggravated sexual assault in Canada depends on the circumstances, for example:
Yes, generally HIV non-disclosure can result in charges for aggravated sexual assault. In its decision in R. v. Mabior (2012), the Supreme Court of Canada held that an HIV-positive person who does not disclose their status to a sexual partner can be convicted of aggravated sexual assault where there was a realistic possibility of HIV transmission. Generally, there is no duty to disclose where the accused has a low viral load at the time of the sexual activity, and a condom is used. However, outside those circumstances, HIV non-disclosure can lead to an aggravated sexual assault charge. These cases require expert medical evidence and engaging an experienced aggravated sexual assault lawyer in Toronto for a tailored legal defence.
In many cases involving aggravated sexual assault, the police may hold you in custody before the bail hearing. In certain cases involving aggravating circumstances, for example, where a firearm was used and the applicable statutory conditions are met, where you were already on release for another indictable offence, or where the offence involves intimate partner violence and you have a prior conviction for an offence involving violence against an intimate partner, you may face the reverse onus. Under these circumstances, you will have to show the court why your detention is not justified. Engaging a bail lawyer in Toronto can help gather the necessary facts while under arrest and propose a bail plan that reflects the seriousness of the charges.
Yes, in Canada, preliminary inquiries are available for indictable criminal offences with a maximum penalty of 14 years or more according to Bill C-75. Since aggravated sexual assault carries a maximum of life imprisonment, an accused may request a preliminary inquiry. The preliminary inquiry allows the court to determine whether there is sufficient evidence for the accused to stand trial.
In most cases, yes. Following Bill S-12 (in force October 26, 2023), registration in the National Sex Offender Registry under SOIRA law is mandatory where the complainant was under 18, the offence was prosecuted by indictment, and the sentence is two years or more, or where the offender has a prior designated sexual offence conviction. In other cases, there is a presumption of registration that can be displaced only where the offender establishes that the order would be grossly disproportionate or have no connection to SOIRA's purpose. Where SOIRA is ordered for aggravated sexual assault, the duration is typically life.
Depending on the individual circumstances, a tailored defence strategy may help reduce aggravated sexual assault charges to a lesser offence. For example, if the evidence does not support the aggravating element, or if there were Charter violations, the Crown may agree to proceed on a lesser included offence, typically sexual assault under Section 271 or sexual assault with a weapon or causing bodily harm under Section 272. At the same time, every criminal case is different, and the outcome in aggravated sexual assault cases will depend on the specific facts.
