>>17807404 (OP)>to more progressive than America?I'm under the impression it was two things:
1. An intense desire to distance themselves from American cultural hegemony. The biggest existential threat at all times to what little identity Canada has is to be completely consumed by their larger neighbor America. This 'dread' has lead to things like the Canadian Broadcasting act and the general modern progressive nature of Canadians.
2. People grossly underestimate how cold and generally inhospitable Canada is compared to America. The geography and the landscape are superficially similar, but the weather and climates couldn't be further from the truth: it gets hot in the summer and it gets artic-cold in the winter, and because of this most people live in Ontario, Quebec, or British Columbia. I mention this specifically because it creates isolated people dependent on the federal government for assistance and is the groundwork for more collectionist attitudes.
With that in mind Canada is currently in a weird cultural economic position because they've been spending quite possibly almost 60-75'ish years just sort of chilling, not thinking about anything too hard, implicitly cooperating with the United States on nearly all matters, and not exactly taking care of themselves. I, or anyone else, could tell you a bunch of things about Canada, but the main deal "right now" is them trying to recover from the whiplash of: assuming America would never take advantage of them or otherwise become "antagonistic" and assuming the free progressive neo-liberal globalist market capitalism Francis Fukuyama prophecy would end.
