Background
G.G. was charged with sexually assaulting his spouse “on or about” April 7, 2021. Both the accused and the complainant agreed that sexual intercourse occurred on the night of April 7 — the last night they slept together in the marital home before G.G. moved out. Their accounts diverged on two points: consent, and the timing of the encounter. The complainant testified the assault occurred at approximately 10:00 or 11:00 p.m., consistent with earlier statements she made to police. G.G. maintained the intercourse was consensual and took place around 1:00 a.m., and further claimed he left the marital home around 9:00 p.m. — before the time the complainant said the assault occurred — and went to a different residence for the rest of the night. He called four alibi witnesses in support of that account.
At trial, the judge accepted the complainant’s evidence on consent and found that G.G. “sexually assaulted the complainant as she described.” Nevertheless, the trial judge acquitted G.G. on the basis that because G.G. had presented alibi evidence to rebut the complainant’s assertion that the assault occurred around 10:00 or 11:00 p.m., the Crown was required to prove beyond a reasonable doubt that the offence happened at that specific time — a burden the Crown had not met.
The Ontario Court of Appeal allowed the Crown’s appeal (2025 ONCA 574), holding that the trial judge erred by demanding proof of timing to that level of specificity. The Court of Appeal set aside the acquittal and substituted a conviction, remitting the matter for sentencing. G.G. appealed to the Supreme Court of Canada as of right.
The Court’s Holding
A unanimous Supreme Court dismissed the appeal. The Court reaffirmed that where a charge alleges an offence “on or about” a particular date, the Crown is generally not required to establish the exact time of the offence. There are two recognised exceptions: where timing is an essential element of the offence itself, or where timing is “crucial to the defence” — most commonly when the accused advances an alibi covering the time period alleged by the Crown. In such cases it would be unfair for the Crown to undermine the alibi by shifting to a different time frame after the fact.
The Court held that no such shift occurred here. The time period the Crown alleged was defined holistically by the charging document, the substance of the complainant’s evidence, the evidence elicited by the Crown at trial, and the Crown’s position throughout — all of which pointed to the last sexual encounter between the parties on or about April 7. The complainant’s cross-examination estimate of “10 or 11:00 p.m.” did not narrow the Crown’s case to that precise window. Because the Crown never claimed the assault occurred at that specific hour, it did not shift the alleged time frame and did not deprive G.G. of his right to make full answer and defence.
The Court also upheld the substitution of a conviction as the appropriate remedy under s. 686(4)(b)(ii) of the Criminal Code. The trial judge’s explicit finding that G.G. sexually assaulted the complainant, read alongside his credibility analysis — including his acceptance of the complainant’s “temperate, detailed, and consistent” testimony and his rejection of defence arguments attacking her credibility — was sufficient to support a conviction beyond a reasonable doubt. The sole error was the trial judge’s mistaken legal conclusion on the timing issue; but for that error, a conviction would have been entered.
Key Takeaways
- The Crown is generally not required to prove the exact time of an offence alleged “on or about” a particular date; timing need only be proved where it is an essential element of the offence or crucial to the defence.
- Timing becomes “crucial to the defence” when an accused advances a genuine alibi covering the time period alleged by the Crown — but whether the Crown has improperly shifted that time frame must be assessed holistically and contextually, not by fixating on a single witness’s estimate given in cross-examination.
- Sexual assault cases warrant particular care: it is not uncommon for complainants to be uncertain or honestly mistaken about the precise time an assault occurred, and that uncertainty should not become a procedural escape route for accused persons.
- An appellate court may substitute a conviction under s. 686(4)(b)(ii) of the Criminal Code where the trial judge’s findings of fact, viewed in light of the correct law, support guilt beyond a reasonable doubt — even if the trial judge acquitted due to a legal error.
Why It Matters
This decision clarifies and reinforces the limits of the alibi-timing exception in Canadian criminal law. By confirming that a complainant’s cross-examination estimate of when an offence occurred does not automatically redefine the Crown’s case to that precise window, the Court prevents a technical acquittal doctrine from being weaponised against complainants whose recollections of exact timing are imprecise — a reality the Court expressly acknowledged is common in sexual assault prosecutions.
For practitioners, the ruling provides a practical framework: courts must look at the totality of the charging document, the evidence led, and the Crown’s position to determine the alleged time frame — not a single answer on cross-examination. It also reinforces the appellate power to substitute convictions where a trial judge’s legal error alone stands between an explicit factual finding and the legally correct verdict, reducing the need for costly retrials in such circumstances.
