Partially competition, as a couple of provinces have large car manufacturing. (Ontario and Quebec, mostly). Partially that there's no repair or maintenance infrastructure, nor guarantee a car will keep functioning if (say) the manufacturer shuts down or a model gets discontinued. As to how much of which, that's a good question, and not one I've seen any answers to.
