Our son is a student at McGill, and we have traveled to Montreal many times to bring him there or home, or just visit. We only stay one night typically, and try to see something new (in a few hours) each trip. We have seen the Olympic stadium, biodome, Notre Dame, St. Joseph's Oratory. My husband isn't really a museum person so we haven't done that, but I think there might be a few he would like. We have been up to Petit Italie, and Mile End. As he will graduate some day, we would hate to find out we missed out on something after all these trips! We have been lucky to have caught the Jazz Festival and Festival of Lights, and loved both.
