Sexual assault law in Canada has changed significantly over the past decade. The Supreme Court of Canada has issued a series of decisions that have reshaped how trials are conducted, how evidence is admitted, and how sentencing is approached.
Anyone working in this area, whether as counsel or as someone navigating a charge or complaint, needs to understand the modern case law.
This post highlights some of the key decisions and what they mean.
R v J.J. (2022): The Constitutionality of Section 278.92
R v J.J. was a constitutional challenge to the section 278.92 regime. The defence argued that requiring advance notice of records the accused intended to use, and granting the complainant standing to participate, infringed the accused’s rights to a fair trial and to silence.
The Supreme Court upheld the regime in a majority decision. The Court found that the privacy interests of complainants and the integrity of the trial process are sufficiently important to justify the procedural requirements imposed on the defence.
The decision resolved earlier constitutional uncertainty and confirmed that section 278.92 applications are a permanent feature of sexual assault trials in Canada.
The practical impact of J.J. is that defence counsel must plan for these applications from the outset of a file. Records in the possession of the accused cannot be used at trial unless advance notice is given and the court rules on admissibility.
R v Barton (2019): Mistaken Belief and Prior Sexual Activity
R v Barton involved a homicide arising from a sexual encounter and addressed the use of prior sexual activity in the context of the mistaken belief in consent defence.
The Supreme Court held that prior sexual activity, on its own, cannot support a defence of honest but mistaken belief in communicated consent. The accused must point to evidence of specific, communicated consent relating to the sexual activity in question.
The Court also emphasized the need for trial judges to guard against myths and stereotypes in sexual assault proceedings. It provided guidance on jury instructions and on addressing improper reasoning in closing submissions.
Following Barton, prior sexual history or a past relationship cannot, by itself, form the basis of the defence. The focus must remain on evidence of consent in the specific circumstances of the alleged incident.
R v Goldfinch (2019): The Boundaries of Section 276
R v Goldfinch involved a sexual assault trial in which evidence of a prior sexual relationship between the complainant and the accused was admitted at trial. The Supreme Court allowed the appeal and set aside the conviction on the basis that the evidence had been improperly admitted under section 276 of the Criminal Code.
The Court emphasized that prior sexual history is not, by itself, relevant to the issue of consent. Even where the parties had an established sexual relationship, that fact does not assist the trier of fact in determining whether the complainant consented on the specific occasion in question.
Goldfinch clarified and reinforced the strict application of section 276. Defence applications must identify specific evidence and connect it to a specific live issue at trial. General references to a prior sexual relationship are not sufficient to meet the statutory threshold.
R v Friesen (2020): Sentencing for Sexual Offences Against Children
R v Friesen marked a significant shift in sentencing for sexual offences against children. The Supreme Court held that sentences in this area had generally been too low and required reassessment to properly reflect the seriousness of the offences and the harm caused to children.
Following Friesen, courts have emphasized significantly higher sentences in appropriate cases involving child complainants, particularly where aggravating factors are present, compared to earlier sentencing patterns.
The Court also confirmed that emotional and psychological harm is as serious as physical harm and does not need to be proven through long-term or permanent effects.
Friesen has also influenced sentencing in adult sexual assault cases. Crown sentencing positions in many jurisdictions have moved upward, and counsel must be prepared for that evolving landscape.
R v Kruk (2024): Common-Sense Reasoning and Credibility
R v Kruk addressed the use of common-sense assumptions in evaluating the credibility of complainants. The Supreme Court held that there is no special rule preventing trial judges from drawing common-sense inferences in sexual assault cases, but courts must remain alert to myths and stereotypes about how complainants behave or how memory works.
Kruk rejected the idea that common-sense reasoning is inherently suspect in sexual assault cases. The Court’s framing has implications for how credibility findings are made and how appellate courts review those findings.
For counsel, Kruk is a reminder that credibility analysis in sexual assault cases must be careful, but still grounded in ordinary reasoning rather than constrained by abstract concerns about reasoning processes.
R v Tsang and R v Reilly: Continued Refinement of Section 276 and Cross-Examination
Recent provincial appellate decisions, including R v Tsang and R v Reilly, have continued to refine how section 276 operates in practice.
These cases address questions like:
- When evidence of prior sexual activity is properly characterized as falling within section 276
- How trial judges should rule on questions during cross-examination that risk straying into prohibited territory
- What remedies are available where section 276 is breached at trial
These decisions are important for trial counsel because they show how the rules are being applied in real cases. The applications themselves get most of the attention, but the in-trial rulings on questions that come up unexpectedly often have just as much impact on the case.
Themes Across the Recent Cases
Several themes emerge from the recent jurisprudence:
- Privacy interests of complainants are real and protected: Both R v J.J. and the section 278 case law treat the complainant’s privacy as a substantive interest that the law must protect, not just a procedural concern
- Myths and stereotypes are still a concern: Despite decades of case law, courts continue to guard against reasoning that relies on outdated assumptions about how complainants behave or how memory operates
- Procedure has substantive consequences: The detailed application regimes under sections 276, 278, and 278.92 mean that procedural compliance now plays a central role in how sexual assault cases are litigated
- Sentences are heavier: R v Friesen and the cases that have followed it have permanently shifted the sentencing landscape upward
- The Supreme Court continues to play an active role: Sexual assault law is a recurring area of attention for the Court, and counsel needs to keep up
Why Staying Current Matters
Sexual assault law in Canada is one of the most actively developing areas of criminal law. The rules in 2026 are not the same as they were five years ago, and they will continue to evolve. Counsel must track decisions as they are released and adjust strategy accordingly.
For both accused persons and complainants, this makes it important to work with counsel who regularly practise in this area and stay current with developments in the law. The procedural and substantive demands of modern sexual assault litigation are significant, and the law continues to change in meaningful ways.
