OK, Denis, it sounds like urban self-defense is one of the things you are interested in.
Honestly, I guess I don't really know what looking to learn now

. I started this thread just wondering about how other Canadians viewed the role of firearms but, logically, this has moved more into talking about self & home defence in general. As this isn't something I've thought too much about any input is welcome.
As far as what we cannot own,
this list from the Canadian Border Services Agency summarizes that pretty well. Also, from what I understand, any object can be legally considered a weapon when the individual's intent is to use it to harm another individual.
I hear you about the training aspect though. I have played with the idea of getting involved in something like martial arts in the past, as much for fitness as preparedness, but ultimately balked at the commitment required.
