Can’t say much about Quebec winters, but, lots of experience with Mazda 3’s in Western Canada, mainly Winnipeg. I’ve rented a few FWD’s with winter tires. They did the job most of the time. The AWD with winter tires is so much better. Never going to be perfect. As far as the mileage difference, in the real world, I’ve noticed just below 2L/100km difference.
