The appellant, Tracy Robinson, appealed convictions for causing damage by fire to property and arson with intent to defraud after a judge-alone trial.
The prosecution's case was circumstantial, relying heavily on an Ontario Fire Marshal investigator's expert opinion that the fire was deliberately set.
The defence presented a counter-expert suggesting an electrical cause.
The trial judge accepted the prosecution's expert and found motive and opportunity.
The Court of Appeal dismissed the appeal, finding no palpable and overriding error in the trial judge's factual and credibility findings, and no unreasonable verdicts.
While the trial judge erred in enunciating the R. v. W.(D.) test, the court found he applied it properly in context.
