I think I will give the USA a miss if I visit Canada. We don't carry weapons here in Australia.
It's not like everyone's walking around carrying weapons and on edge man.
I get out a bit and I've literally seen one open carry in like two years, but it could be my area.
Either way, owning them doesn't mean you're paranoid or setting up your home for a siege or anything, and it doesn't mean you bring them everywhere (some do).
It's having them incase the situation arises - home protection, etc. And they're fun to shoot.
