My take has always been that we have strong regional cultures over a unified Canadian cultural identity. The U.S has a little bit of this as well, but not in the same way/with more stuff to point to in terms of national identity.

Edit: Actually, here’s a good experiment for anyone who wants to think about this more. Take a look at some of the Canadian TV shows and movies that have actually been successful, and people abroad may point to as representative of Canadian culture. What about them is distinctly Canadian, over [x]-Canadian? Can start with the obvious (Trailer Park Boys, Letterkenny, Schitt’s Creek, Kim’s Convenience, FUBAR), but I’d bet folks may find this holds across some less obvious ones too.
