Not legally. If you have a lease in your name in Montreal, and no stronger evidence of primary residence elsewhere to make the claim that the Montreal place is for vacation only, you will need to switch your residence. Also, if you intended to use Quebec health services you will need to get your health card for that province.

I believe the only people who can legally do what you are describing are university students from out of province. 

It isn’t a matter of where you physically are on December 31st.

You would almost certainly be a resident of Quebec if you follow your plan.

Sections 1.2, 1.3, 1.11, and 1.14 are applicable here.

Since you are rent-free in Vancouver, my suggestion would be to rent/stay in Montreal for no more than 6 months. That way you can enjoy Montreal, reduce some of the travel costs and travel time, and still be considered a B.C. resident.

You can also look at these pages to see if you could declare yourself as a resident of Nunavut, there's a northern residents tax deduction that would be nice if you could have it. I suspect that RichMoose is right though, and you'll probably have to be a resident of Quebec.
