The accused was charged with sexual offences against his natural daughter.
At trial, the central issue was credibility.
The Crown sought to introduce similar fact evidence from the daughter of the accused's common law wife, alleging that the accused had previously engaged in similar sexual misconduct with her after establishing a father-daughter relationship.
The trial judge admitted the evidence and convicted the accused.
The Court of Appeal upheld the conviction.
The Supreme Court of Canada dismissed the appeal, holding that the similar fact evidence was properly admitted.
The Court affirmed that while evidence adduced solely to show propensity is generally inadmissible, similar fact evidence may be admitted if its probative value outweighs its prejudicial effect.
In this case, the evidence was highly probative on the issue of credibility.
