BBC:

Some words refer to things Americans don’t seem to have: toque for a kind of fitted knitted hat; poutine, Nanaimo bars, and butter tarts for three of Canada’s great culinary gifts to the world if the world would but accept them; Caesar for a bloody Mary made with clamato juice (tomato plus clam).

These Canadianisms stand as evidence of the difference between Canadian and American culture. It is very important for Canadians to maintain that difference, even if people from Vancouver sound more like people from San Francisco than people from San Francisco sound like people from San Antonio.

Until I moved to the US, I had no idea that Butter Tarts were Canadian. If you get a chance, try them. They are delicious.
