The appellant, Joshua Barreira, appealed his 15-year sentence for manslaughter, which had been reduced to a net 4.5 years after pre-sentence custody credit.
He raised four grounds of appeal: the sentence falling outside the appropriate range, the sentencing judge's failure to assume he did not know his accomplice had a gun, insufficient "Duncan credit" for harsh pre-sentence custody conditions, and an omission of pre-sentence credit for time served between sentencing submissions and the imposition of sentence.
The Court of Appeal granted leave to appeal and allowed the appeal in part, accepting the fourth ground as conceded by the Crown.
The court rejected the other grounds, affirming that the sentence was not demonstrably unfit, that mitigating facts must be established on a balance of probabilities, and that the "Duncan credit" was within the sentencing judge's discretion.
The sentence was adjusted to reflect the additional pre-sentence credit.
