Honestly we forget about Canada, in a way. Having the US so close geographically and culturally has made it hard to see anything else. I can think of three distinctly Canadian dishes, and two of them have only stayed Canadian because they involve ingredients Americans can't get.
The Anglo-Canadian identity is pretty much just "we're not American" and having an inferiority complex. It's been weirdly natural for people to switch to thinking of America as the enemy.
while I know about all the shitty pizzas the US made up in a century.
Yep, none of that was us. For sure. /s
