Actually gnu, the Canadian Criminal Code does include the right of citizens to use deadly force to protect themselves (sections 34, 35 and 37). The key provision in the Canadian criminal code (34) is that, "no one may use more force than is necessary and then only when he believes, on reasonable grounds, that he can not otherwise preserve himself from death or grievous bodily harm".

I didn't know that until I looked it up. I, like you, assumed you couldn't use deadly force. So in other words, you can kill someone in self defense, but you better use a shotgun or your bare hands, because as most Canadians know, you can't use a handgun, because they are illegal. And you better have the money for a damned good lawyer after the fact.
