One more option for maple syrup lovers -- tire d'érable, a taffy made by cooking the syrup until thick, then pouring it over snow and twisting it around a popsicle stick.

Do take a good look at the hat the vendor is wearing. It looked like a coonskin cap from a distance, complete with furry tail, but it was actually a fox. It creeped me out.
