<human>: This morning I was walking in the underground path in Toronto, and was asked nicely by a lady from Indiana for directions. I ended up walking her and her husband to their destination, as the underground is an absolute maze and I was heading in a similar direction.

On the way, I struck up conversation and the lady asked about the shopping in the city.  Specifically, she asked if the stores accept American money, to which I confirmed that most stores do, though, given that the Canadian dollar is above parity, they should expect to pay more in equivalence.  

The lady looked shocked.  She told me that she thought that the US currency was the primary currency in Canada. When I told her otherwise, she barely believed me.  When I told her again that the Canadian dollar is currently valued higher than the American dollar, she laughed, but saw my face and stopped abruptly.

Now, this lady was not overly old; probably in her late forties or early fifties.  And I know, the typical Redditor at least *appears* to be of decent intelligence and awareness, but I feel like I should still ask.  Do Americans have any clue about the Canadian dollar?

Can you summarize the given text in a few sentences?
<bot>: Met an American today who thought that Canada used the American currency and was shocked to find out otherwise. Is this typical of Americans?
