The article says "New Canadian research shows one young person is shot almost every day in Ontario, with the vast majority of injuries being unintentional". 

I have a feeling guns are injuring more innocent Canadians than are injuring or killing criminals.

I have a feeling Canadians are shooting and injuring more innocent Canadains than shooting, injuring and killing criminals while Canadians try to protect themselves.

If Canadians are getting guns to protect themselves, they aren't doing a very good job of it.
