Well, those Ayrabs would probably be inhibited about attacking the West Edmonton Mall or anything in Alberta. Maybe Toronto? Hard to tell. There are many malls in Canadia.
I would guess Toronto. There is a really big mall there that I have been to once, but don’t remember the name. It was big and busy. It would be an easy target. No concealed carry = soft target. I would not go there today. Some malls around where I live are identified as no carry on the web, but they have no signs on the doors. I carry there to pick up the spousal unit because it is a soft target.
