According to this CTV News article:

The third guy shot and killed in that spate of violence is a Mr. Riccardo Ruffolo, 34. I couldn't find a thing on him, but the article says he's a convicted drug dealer with slight ties to the Montreal Mafia, specifically Vincenzo Armeni, a drug dealer serving a 20 year prison term who is a known mafia associate/possible member.
