cherry | Quick Question

For our trip next year, we're hitting Toronto-Ottawa-Quebec City-Montreal. Since we have to have a teacher with us, we don't have complete control over where we're going, but I was wondering if anyone knew of some good, (Interesting/fun) places to hit while we were there. The teacher coming with us is organizing the educational stuff, but we have to find the fun stuff ourselves.

Don't suppose anyone has any ideas?
