The language around crossbows is a leftover from an old Criminal Code provision that was repealed, I believe, through the Statutes Repeal Act. It had a specific offence for crossbows as a result of an event that occurred about 15 or 20 years ago, when someone used a crossbow to.... I think they murdered a counsel. That was specifically added into the Criminal Code.
Crossbow references were left in the Criminal Code after that offence was repealed. They are left over from that offence. I think it was subsection 97(1), which was repealed.
