Calgary has an awesome trail system that will get you - if you know the network - almost anywhere in the city with very little street traffic. Edmonton infrastructure and general cycle awareness (as well as advocacy) seems far better than Calgary. It's been several years since I've ridden in Vancouver, but I used to love it. I never had any issues with traffic. If they're working on infrastructure there, that's great. I haven't ridden in Winnipeg or TO. If vehicle traffic is anything to go by, I might be nervous riding in Montreal! Anybody know how Montreal is to get around in?
