During a jury trial for homicide, the Crown brought a mid‑trial application seeking to introduce similar fact evidence of the accused’s alleged violent conduct toward individuals he believed to be paedophiles, including an assault on another inmate while in custody after the charged offence.
The Crown argued the evidence was relevant to motive, animus, intention, and to cross‑examine a defence psychiatric expert regarding the accused’s mental state.
Applying the framework from R. v. Handy, the court held that although the evidence had some relevance to hostility toward paedophiles, its probative value was significantly reduced because similar animus was already before the jury and the proposed incident occurred two years after the alleged homicide.
The court found the moral and reasoning prejudice from introducing the detention‑centre assault—particularly a surveillance video—far outweighed its probative value and risked diverting the jury from the issues in the trial.
The Crown was therefore prohibited from adducing evidence about that assault but was permitted limited cross‑examination about other admitted past altercations and hostility toward child molesters.
