Two things you've got to remember when visiting Montreal, 1. get a metro card, the more days the better, it'll get you all around town without worrying about parking. 2. Visit the biodome so you can help with funding the cause. I spent over 30 minutes watching their otter display, because it was feeding time and he was hyper and running/swimming all over the place. The beaver was doing some laps around the pool and scaring the ducks, pretty funny. Make sure you don't take your camera out during the first exhibit, the rain forest, because it'll fog it up and probably mess up its internals. A great place for kids.
