for home...
Tastykakes
cheese steaks (I find it really funny when places up at school have "Philly Cheese steak" on the menu... what they serve is nothing close!!)
water ice (some people call it Italian ice) -- it's kind of like a slushy, only thicker, and you eat it with a spoon... hard to explain, and not the stuff you get in the little cups from the supermarket (

for school...
yeah, poutine. I'm afraid of it... but most people here eat it like it's their job.
I've also never seen Greek Chips anywhere other than Lennoxville...
