This is the kind of thing that just seems like a very unlikely scenario. If hyper inflation a economic collapse come about, AND the Canadian government decides to enact martial law and confiscate all arms as a result, I suppose the majority of Canadians would not be very happy about it.
But this is a very unlikely scenario. Even more unlikely in the US, though there are plenty of survivalists who seem to think this is already happening. It borders on science fiction, where the parameters of doom are already set, all we need to fill in the drama. Go outside this little circle of doomers we occupy, and most regular folks think this sort of fatalistic belief is just nutty, sounding like the rantings of the guy pushing a cart through skid row and talking to himself.
