I've no idea how to guarantee that a car rental company gives you winter tires instead of simply all season tires though.
I have never seen winter tires on any cars in the US so I wouldn't bank on this.
If you rent from Montreal (YUL), you will be guaranteed winter tires between Dec 1 to March 15 as it is a mandatory law.
