Don't you guys find it sad that our country's culture is just a sum of dumb stereotypes? (maple syrup, beavers, hockey, winter, eh, indians, celine dion,...).
I mean, what other country in the world has a cheap donuts shop as a national icon?
I guess it has to do with being a young country. Australia has pretty much the same problem. (kangaroos, boomerangs, beaches,...)
No one associates Canada with Tim Hortons except Canadians - its simply not known outside our countries.
And the donut will remain an American creation to most, even if I think we technically consume more per capita than anyone else in the world.
