The Post-Apocalyptic Roadmap/Canada

Eastern Canada

Hmm... I wonder how Toronto would fare. It is a huge (for Canada) city, but... I don't think it has much military, or political importance (on a international stage). It has tons of economic importance, but I don't imagine that be as important for the initial strikes.

Perchance, Toronto doesn't get hit. That would become then a mecca for survivors from both Canada (Ottawa, and our military towns/cities (especially the big ones in Quebec) and the Northern States.

With its access to the Great Lakes and then St. Lawrence (could hit up any surviving US cities along the way) and then Atlantic Ocean and major airports it could become a major Trade city from the get-go. Most likely mainly with ships and not aircraft.

To add to that, it is also incredibly multicultural we could see race riots break out in places like Chinatown as the populace finds out who dropped the bombs.

Western Canada

Calgary is globally notable for one reason only. It has a large number of corporate headquarters regarding the oil fields projects. A strike to downtown could decapitate a number of Canadian oil producers. On the other hand, Edmonton is the provincial capital (legislature, &c) and also has a large number of corporations located there. It it decently close to an army base (which might attract some missiles).

The plains provinces (Alberta, Manitoba and Saskatchewan) have a very hardy agricultural and ranching base. I envision that a large number of urbanites flee south in the face of collapsing infrastructure (electricity, &c) while ruralites continue their way of life, though their technology quickly moves a few decades back as they face mounting maintenance problems.
