The appellant was convicted of arson and unlawfully producing cannabis resin after a fire broke out in his mother's basement.
The Crown's expert testified the fire was caused by the ignition of butane vapours from the production of butane honey oil.
The appellant appealed, arguing he received ineffective assistance of counsel because his trial lawyer failed to seek legal aid funding to call a competing fire expert who had concluded the fire was caused by a faulty extension cord.
The Court of Appeal dismissed the appeal, finding no miscarriage of justice.
The trial judge had considered the competing expert's report and correctly concluded it was flawed and would not have affected the verdict, as it focused only on the ignition source and ignored the fuel source.
