^ It is very unlikely you will get any detailed practical advice *publicly* from a Canadian who has a clue. We all know better. We only talk about other people who did this and that...of course.

I guess since intent figures so prominently into things it's likely not too wise to spell out any sort of plans in this area publicly.
Honestly, the reason for this post was, like jzmtl's comment earlier on, given our regulated environment I can't really see a very large, practical role for firearms in urban Canada and I was wondering if I was missing something or if this is indeed the case.
I'm leaning towards the thinking that things like home hardening, alarms, and even super-bright flashlights like you mention are all much more practical areas to focus upon. And, for being out and about, perhaps some self-defence or situational awareness training could be beneficial.
