Canadian beer in the states is not canadian beer. It's all 4% max and tastes like watered down crap. I feel bad for the poor US, I don't know what I'd do without Canadian beer.... ~tear~ Wait, I'd move to Canada, that's what I'd do
to answer your question:
Molson Canadian and Labatt Blue are sold outside Canada. You won't find Keiths, or moosehead though.
