A sexual assault charge is one of the most serious allegations you can face. The potential consequences include lengthy prison time, sex offender registration, providing DNA sample, and weapons prohibitions. Conviction could also result in immigration consequences for foreign nationals and permanent residents. The stigma associated with these allegations is immediate and affect every part of your life. Sexual assault cases have unique evidentiary rules under the Criminal Code, and require a defence lawyer who knows those rules.

The spectrum of sexual offences

• Sexual assault – 271. The core offence: any touching of a sexual nature without consent. Hybrid; maximum of 10 years on indictment and 14 years for victim under age of 16.
• Sexual assault with a weapon, threats, or causing bodily harm – 272. Indictable; maximum 14 years, or life if victim under 16.
• Aggravated sexual assault – 273. Indictable; maximum sentence: 14 years to life.
• Sexual interference – s. 151, invitation to sexual touching – 152, sexual exploitation – s. 153. Maximum sentence 14 years.
• Child pornography offences – s. 163.1. Possession, accessing, making, and distribution of photograph, film or video of sexually explicit content depicting a person under the age of 16. Maximum sentence: 10-14 years.
• Luring – 172.1. Maximum sentence: 14 years
• Voyeurism – 162 and publication of intimate images without consent – s. 162.1.

The Crown’s theory – and where it can fail

To convict of sexual assault under s. 271, the Crown must prove:

• The touching occurred
• The touching was of a sexual nature
• The complainant did not consent
• You knew the complainant did not consent, or were reckless or wilfully blind as to consent

In Canadian law, consent is subjective. It is based on complainant’s internal state of mind at the time. There is no consent where it is given by someone other than the complainant, where the complainant is incapable of consenting (including by intoxication beyond the capacity threshold), where consent is obtained by abuse of trust, power, or authority, where the complainant expresses a lack of agreement to engage in the activity, or where, having agreed, they express a lack of agreement to continue.

On the fourth element, mistaken belief in communicated consent remains a defence. But under s. 273.2 of the Criminal Code and the Supreme Court’s decision in R v Barton, 2019 SCC 33, that defence is tightly confined. The accused must have taken reasonable steps to ascertain consent and must point to a belief in communicated consent, not assumed consent.

The rules of evidence that change everything

Sexual offence prosecutions are governed by specialized evidentiary rules that do not apply in other trials. These are the battlegrounds that experienced defence counsel work in:

Section 276 applications – “rape shield”

The Criminal Code restricts questioning of a complainant about prior sexual activity, whether with the accused or others. Admission requires a pre-trial application with specific notice and content requirements. Getting this wrong could end your ability to cross-examine on a critical issue. This application is needed even when the prior unrelated sexual activity defence intends to question about is with the accused. The recent Supreme Court decisions in sexual offence cases have made the requirement of these applications necessary before questioning about any touching of sexual nature with the accused, even moments before the alleged non-consensual touching.

Section 278 applications – third-party records

Access to a complainant’s counselling, medical, school, or similar records is governed by a two-stage Mills regime (R v Mills, 1999 CanLII 637). These applications require detailed grounds and often a privacy lawyer for the complainant.

The accused must establish that the record is likely relevant to an issue at trial or to the competence of a witness to testify, and that production of the record to the judge is necessary in the interests of justice. This requirement arises under s. 278.5(1) of the Criminal Code. In Mills, the Supreme Court explained that Parliament intentionally moved beyond the earlier O’Connor framework by requiring not only likely relevance, but also that judicial inspection itself be necessary. The Court stated that once likely relevance is established, the requirement that production to the court be necessary in the interests of justice gives the trial judge discretion to consider the full range of rights and interests before ordering production.

Section 276.1 “own records” regime

Following Bill C-51 (2018), even records in the hands of the accused such as texts, emails, photographs, may require an admissibility application before use at trial where they relate to the complainant’s sexual activity.

KGB, Vetrovec, and collateral-fact rules

The defence must also navigate prior inconsistent statement rules (R v B(KG)), warnings about unsavoury witnesses (Vetrovec v The Queen), and the rule against collateral-fact cross-examination.

What defence looks like in practice

Beyond the applications above, defending a sexual assault case typically involves:

• Detailed review of disclosure – video statements, text communications, photos, medical records, 911 call logs, witness statements.
• Expert evidence if required, defence lawyers must ascertain if an expert will be required to advance defence theory. Experts may include toxicology on incapacity cases, forensic evidence review or IT experts to retrieve electronic data from devices.
• A decision on election – Supreme Court judge alone, judge and jury, or Provincial Court
• Possible preliminary inquiry where available to test the complainant’s evidence (now restricted to indictable offences with maximums of 14 years or more under s. 535 as amended)
• Trial strategy focused on the Crown’s burden – the defence does not need to prove innocence; the Crown must prove each element beyond a reasonable doubt

Consequences beyond sentence

Conviction for most sexual offences means:

• SOIRA registration under the Sex Offender Information Registration Act, for 10 years, 20 years, or life. This is not mandatory but is often sought by Crown.  
• Mandatory DNA order under s. 487.051
• Weapons prohibition under s. 109
• 161 orders prohibiting contact with persons under 16 and presence at parks, schools, and similar places
• Immigration inadmissibility for foreign nationals and permanent residents
• Permanent Vulnerable Sector record disclosure

These are reasons to fight the case, not to plead it out casually. Speak to defence counsel before you speak to anyone else.
