Summarizing the social liberal aspect of Canada by the legalization of marijuana seems very narrow minded. There are far more important social aspects than marijuana legalization.
Agreed, like I said, "in some ways". Of course, there are more important social aspects, and it's not an in-depth analysis of the two cultures and it wasn't meant to be -- it simply highlights just how open-minded Americans can be and how conservative Canadians can be and that's all it was meant to be.
