We faced this same issue. We ended up selling our car in Canada and buying cars in the US once we moved. We determined it was the best route for us to take so that we didn’t have to pay the car off with our own money, we could avoid the hassle of importing/registering, and avoid the issue of the car being in KM when the US is miles. We owed quite a bit on the loan. Tried to go back to the dealer we bought it from and sell it back, but they were going to really rip us off. Selling back to the dealer meant we would only get enough money to pay back part of the loan, and would have to pay some out of pocket. So we posted the car on FB marketplace and found a buyer within a day. The buyer purchased from us with a cashiers check and we then used the money to pay off the loan. With it being such a high amount I thought the buyer would ask if we still had a loan on the car but they didn’t. If you sell your car in Canada, at least in the province we were in, there is no title. The buyer just takes the purchase agreement to the registry and transfers to their name. Nothing flags the car is still under lien unless the buyer pays for an advanced search which they usually don’t. It was still a hassle as it is with such things, but it all worked out for us for the best.
