maybe its possible but you need to be hardcore to do that. i live in the gaspe peninsula and winter here is realy harsh. i now its not that bad in montreal weather wise but still lots of minus 20.also i dont think boats are insulated enought to keep warm in the winter and last i heard its realy hard to find a slip in montreal maybe oka or the surrouding have available slip to rent but again never saw one open in winter.
i have wonder the same thing myself to live aboard all year long but i dont think its possible. i wish.......
