I know there is a place in Ill de Boucherville(national park) where people can rent canoe, kayak, or even yacht. For a 6 person canoe, it costs about 12 or 13 CAD an hour. The canoe is something different from the one we used to boating in Beijing, more narrow but much faster.
There are also playground for kids and plenty of space good for BBQ.
I am not sure if any bus can reach there:confused:
