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.
SCTV, specifically Bob & Doug. SCTV was asked to add two minutes of explicitly Canadian content to an already very Canadian show and the result was the Great White North and the Mackenzie brothers.
