Every once in a while I come across some early mid century book that is handwringing about the increased "Americanization" of Canada so I think at some point perhaps there was more distinction. A lot of the anxieties around the free trade debates in the 1980s were about this.

But in general the relationships in NA work more North/South than East/West and the construction of Canada is fairly contrived. So while Canadians have a lot in common with Americans just across the border, this may be more regional cultural relationships. I would posit that your typical Seattle area Washingtonian has a more common culture with a nearby Vancouverite than they would with someone from Florida, Texas or New York.
