Aggravated Sexual Assault: What Counts and the Penalties

Aggravated sexual assault means a sexual assault that also wounded, disfigured, or seriously harmed another person, or put their life in danger. The longest sentence is life in prison. Some cases carry a minimum prison term. That includes using a firearm, or assaulting someone under 16.

Aggravated Sexual Assault, as stated in Section 273 (1) of the Criminal CodeA federal act codifying most criminal offences in Canada, is a charge applied when a complainant either suffers physical harm or experiences fear for their life during a sexual assaultApplying force, threatening force, or causing someone to believe force will be used without consent.. This is more than the absence of consent; the prosecution must prove an intentional application of force resulting in significant bodily harm or imminent danger. Non-disclosure of HIV-positive status can also constitute aggravated sexual assaultSexually touching another person without their consent if it endangers a partner. This charge is always treated as an indictable offenceA criminal activity, carrying strict penalties potentially up to life imprisonment, especially if a firearmA barrelled weapon capable of firing a projectile that can cause serious injury or death. is used, the offence is connected to a criminal organization, or if the victim is under 16. Convictions usually come with additional orders such as staying away from areas with minors and providing biometric data to relevant databases.

What is Aggravated Sexual Assault?

Section 273(1) of the Criminal Code creates the offence of aggravated sexual assault. A person commits this offence when, in the course of committing a sexual assault, they wound, maim, disfigure, or endanger the life of the person they assaulted. Any one of those four things is enough to make the assault aggravated. This is the most serious of the three sexual assault offences in the Code, reflecting the severe physical harm caused to the person.

What is Needed to Convict

To convict you of aggravated sexual assault, the Crown prosecutorA lawyer who conducts a criminal prosecution on behalf of the public. must prove that a sexual assault happened. The Crown must also prove that, while committing the sexual assault, you wounded, maimed, disfigured, or endangered the life of the complainant. It is not enough that the complainant feared for their life; the issue is whether their life was actually endangered, or whether one of the other serious harms in s.273 was proved.

In some HIV non-disclosure cases, courts consider whether there was a realistic possibility of transmission. The Supreme Court of Canada has held that, on the evidence in that case, a realistic possibility of HIV transmission was generally negated where the person had a low viral load and condom protection was used. This is a technical and fact-specific area of law.

In all aggravated sexual assault cases, the Crown must prove the sexual contact was intentional and that you knew the complainant did not consent, or were reckless or wilfully blind about consent. For the assault to be aggravated, the Crown must prove serious harm, including wounding, maiming, disfigurement, or danger to life. The Crown does not have to prove that you intended that level of harm.

Treated as an Indictable Offence

Aggravated sexual assault is always an indictable offenceA more serious type of Canadian criminal offence., meaning that the penalty upon conviction is more severe than with a summary convictionUsed for lesser offences.

Penalty for Aggravated Sexual Assault

A conviction for aggravated sexual assault triggers several consequences by law in addition to the prison sentence.

DNA databank: The judge is required by law to order a DNA sample to be taken and added to the National DNA Data Bank. This happens automatically on conviction, with no exception.

Sex offender registry: In most cases, the judge is also required to make an order under the Sex Offender Information Registration Act (SOIRA), placing the person on the national sex offender registry. Whether registration is mandatory in a particular case depends on how the matter was prosecuted, the specific sentence imposed, and the age of the person assaulted, but for a serious offenceAn indictable offence with a maximum punishment of five years or more. like aggravated sexual assault the order is required in the vast majority of cases.

Prohibition order (s. 161): Where the person who was assaulted was under 16 years of age, the judge must consider, and may make, a prohibition order restricting what the person convicted can do and where they can go. This can include bans on attending public parks, playgrounds, schools, swimming areas, and other places where children are likely to be present, as well as bans on contacting people under 16 and requirements to stay away from the victim's home. The order is not automatic, but the judge is required to turn their mind to it.

Possible Defences and Legal Issues

Consent rules and limits on belief in consent

For aggravated sexual assault, the Crown must prove the sexual assault and must also prove that the complainant was wounded, maimed, disfigured, or that their life was endangered. The same Criminal Code consent rules apply, and those rules also limit when a belief in consent can be raised.

Consent means the voluntary agreement of the complainant to engage in the sexual activity in question, and consent must be present at the time the sexual activity in question takes place. The Criminal Code also lists situations where no consent is obtained, and that list is not exhaustive.

Section 273.2 says it is not a defence that the accused believed the complainant consented in certain situations. These include where the belief came from self-induced intoxication, recklessness or wilful blindness, or where the accused did not take reasonable steps, in the circumstances known to the accused at the time, to ascertain that the complainant was consenting. Whether any of this applies depends on the exact charge, the facts, and the evidence.
