I'd say 50% of Canadians would not know that . And 98% would not that Santa Fe is the capital , while 10% would assume that it's Albuquerque.New Mexico is a state in USA. How many people in USA and Canada do not know this? I think its about 70 percent.
While 10% of Canadians will be able to carry on a conversation about American history, politics and geography like an American born . For that you can blame TV, movies, history listens and self interests.
You are pretty hard to miss compare to us with 1/10 of the population and not the first destination when Americans think exotic spot for a vacation .
I skied throughout new England in my youth and we could be 60 miles from the border and friends talking about Canada ( I did not speak English back then) with American people and they were talking assuming almost a wall of ice at the border. On the other hand the avid American skiers wanting a jump start on the season were up in Québec early November and always interested about everything from history to politics. In my mind it's a question of opportunities and interests or self interests to know about your neighboring country.
You must be well above average in the US with your knowledge of Canada because of your regular traveling north of the border and interests in hockey....oh forgot to mention and Canadian women....👍
