Background
C.P. was charged with multiple serious sexual offences against his biological daughter, including sexual assault, incest, sexual interference, and human trafficking offences. The complainant, who was between 14 and 15 years old at the time of the alleged offences, had experienced a difficult childhood: she and her brother had been placed in foster care as toddlers, lived with adoptive parents for roughly 12 years, and after that placement broke down, came to live with the respondent and their biological mother, then with the respondent alone. The alleged offences occurred during an approximately three-month period while she was living with the respondent.
After a ten-day trial before Justice Brian D. White of the Ontario Court of Justice, the respondent was acquitted on all charges. The trial judge found that while there was some confirmatory evidence, the Crown’s case rested substantially on the complainant’s testimony. He identified material inconsistencies going to her credibility, and reliability concerns arising from evidence—given by the complainant herself, her adoptive mother, and her brother—that she had experienced hallucinations and delusions during the relevant period, had stopped taking her prescribed medication, and had been consuming heavy amounts of street drugs. The Crown appealed all acquittals.
Because the respondent had a history of homelessness and was at times unreachable, the Court of Appeal appointed amicus curiae in September 2025 to respond on his behalf. The respondent was located shortly before the March 30, 2026 hearing and given the opportunity to attend by phone.
The Court’s Holding
Writing for a unanimous panel (Trotter, George, and Copeland JJ.A.), Justice Copeland dismissed the Crown’s appeal. The Crown’s right of appeal from an acquittal is confined to questions of law under s. 676(1)(a) of the Criminal Code, and the Crown must also establish that any identified legal error might reasonably have had a material bearing on the acquittal (R. v. Graveline, 2006 SCC 16). The Court found no legal errors and therefore did not need to address materiality.
On the first ground — that the trial judge impermissibly relied on myths and stereotypes about persons living with mental illness — the Court held that the trial judge did not engage in prohibited reasoning. He did not conclude that the complainant was unreliable simply because she had a mental health diagnosis. Rather, there was a concrete evidentiary foundation for his reliability concerns: testimony from the complainant herself, her adoptive mother, and her brother established that she experienced hallucinations and delusions during the period of the alleged offences, that she had stopped taking her prescription medication at that time, and that her symptoms worsened without medication. The trial judge was not required to accept the complainant’s characterization that her hallucinations were caused solely by street drugs, and the cause of the symptoms was in any event immaterial to whether a sufficient evidentiary foundation existed. The Court also rejected the Crown’s argument that defence counsel violated the rule in Browne v. Dunn by failing to specifically put to the complainant that her hallucinations were caused by her underlying medical condition rather than drug use; the defence was not seeking to contradict the fact of the hallucinations, and had cross-examined her on her discontinuation of medication.
On the second ground — that the trial judge considered evidence piecemeal and applied the reasonable doubt standard to individual pieces of evidence rather than the whole — the Court was equally unpersuaded. The trial judge had explicitly self-instructed that the reasonable doubt standard applies to the evidence as a whole, not to individual pieces, citing R. v. Morin. The Court examined the specific passages the Crown relied upon in oral argument — the hotel elevator witness and the respondent’s silence in response to a sexualized text message — and found that in both instances the trial judge’s reasoning was grounded in the evidence as a whole. Following R. v. G.F., 2021 SCC 20, the Court cautioned against finely parsing a trial judge’s reasons in a search for error.
Key Takeaways
- A trial judge’s reliability concerns about a complainant’s evidence do not constitute reliance on myths or stereotypes about mental illness where those concerns are grounded in case-specific evidence — such as first-hand testimony about hallucinations and delusions during the relevant period, corroborated by family members — rather than in the diagnosis alone.
- The rule in Browne v. Dunn does not require defence counsel to cross-examine a complainant on the specific cause of symptoms she herself acknowledged experiencing; the obligation is to confront the witness on matters the defence intends to contradict, not to explore every inferential pathway the Crown might later wish to foreclose.
- Brief passages in trial reasons must be read in the context of the reasons as a whole; isolated quotations that superficially resemble piecemeal reasoning will not establish legal error where the reasons demonstrate a holistic analysis.
- The Crown’s narrow right of appeal from an acquittal — limited to questions of law under s. 676(1)(a) of the Criminal Code — provides meaningful protection against appellate re-weighing of credibility findings that were properly open to the trier of fact.
Why It Matters
This decision reinforces the boundary between permissible case-specific reliability findings and prohibited stereotype-based reasoning under R. v. Kruk, 2024 SCC 7. Prosecutors and defence counsel in sexual assault cases involving complainants with mental health histories should note that the determinative question is whether the trial judge’s concerns are anchored in concrete trial evidence — not whether a diagnosis exists. A robust evidentiary record (here, the complainant’s own testimony, corroborated by family members) can support reliability concerns without offending the rule against mythological reasoning.
The decision also serves as a reminder of the institutional constraints on Crown appeals of acquittals. Appellate courts are not a venue for relitigating credibility assessments, and the requirement that any legal error have a material bearing on the acquittal sets a high bar. Defence practitioners can point to this case as an example of a thorough, self-aware set of trial reasons that withstood appellate scrutiny on two distinct legal grounds.
