Edit: I got it - my bet is Charlottetown, PEI, because those Anne of Green Gables books were wildly popular on the international market, and I imagine fans tried to find Avonlea on a map and learned that Charlottetown exists.
I'm probably still wrong, this is actually kind of a tough question.
Edit 2: Nah I change my mind, maybe Gimli, MB because the Gimli Glider incident did garner quite a bit of attention.
