For me it’s Corner Gas. I still think it’s pretty funny and there’s a decent amount of references to Canadian stuff but not enough to be off-putting. I feel like an American wouldn’t be confused watching it even if some of the references get a bit dated overtime.
I have only seen a bit of the animated version in waiting rooms.
Someone below reminded me of Letterkenny, it is definitely full of Canadian culture. There’s Murdoch Mysteries which has lots of historic Canadian sites. There’s Trailer Park Boys, and lesser known was Psy-Factor (?) which was a Canadian X-Files.
