Yes, organized crime and street gang members, as well as bikers and mafia members, use illegal weapons almost exclusively, if not 99% of the time. In fact, it is not attractive for organized crime members to use legal weapons because they are generally unlicensed and it is too risky for them to go to a legal place to obtain a weapon that would be legal in Canada.
The seizures that have been made and the experience prove that. I can say, based on the contacts I have with my colleagues who are still active, that the weapons that kill and those that injure, especially on the streets of Montreal—I used to work for the Service de police de la Ville de Montréal, or SPVM—are illegal weapons. It's very rare that we see legally acquired weapons or stolen weapons from legal gun owners.
