I think Quebec has (or at one time had?) the lowest because you’re not required to have collision insurance. You can have just liability, but if your car is a piece of shit you’re not required to insure it for repair should an accident occur. I could be wrong, and I’d love to know if I am.
In my city you are required to have both liability and collision even if the car is worth a dollar. That is true across all of Canada to my knowledge, with the exception of Quebec.
