I grew up in Montreal and I can assure the original poster that Canadian beer was indeed stronger the American beer.
Even American beer in the Montreal market was stronger.
For example, Budweiser in Canada was 5.0% alcohol by volume and the same beer in Vermont was only 3.2%. All of the Canadian brews in Canada were 5.0 also, and the export version in Vermont was 3.2% Including Molson Canadian and Export, Labatt Blue and such.
Of Course this was mid to late eighties before all the ICE, Dry and what not labels started becoming trendy.
So...it was not a myth then.
This without even mention of the high test, speciality seasonal carnival brews or my favorite year rounder: Molson Broduer (I can't even remember how to spell it!) which was nice smooth 6.2 percenter.
Anywho, we called a 24 pack of cans a two-fer or a suitcase.
It's been so long since my days in the McGill ghetto I don't know what is up anymore.
Very much looking forward to my pilgramage this summer to introduce the little one to some family and old friends.
And for the record Canadians DID NOT invent beer, the ancient egyptians did. In fact they are given a kudos from Plato for their invention. Canadians just perfected it
