"Having adduced the evidence of the finding of the shotgun, its seizure and its characteristics, the Crown was entitled to invite the jury to conclude that the gun was used in the robbery. Such a conclusion would no doubt provide powerful evidence in corroboration of the other evidence of identification of the applicant. Alternatively, even if the jury were not prepared to conclude positively that the seized gun was used in the robbery, the evidence of its being found at the applicant's house, and being of exactly the same kind as that used in the robbery, could be added to the other circumstantial evidence of his involvement in the robbery.

This was not a case in which the Crown sought to rely on evidence of similar facts, raising the question whether evidence of propensity might properly be directly or incidentally admitted.
