A six-year prison sentence for a policeman in the shooting death of a teenager three years ago was a rare conviction in Canada, where activists say officers too often get off easy in brutality cases.
The case, along with the weekend death of a black man who witnesses say was beaten by police officers, has also brought race relations in Canada to the forefront.
The 2013 shooting, which occurred after an altercation on a streetcar with the teen, who was brandishing a knife, was caught on video and led to widespread protests in Toronto.
