Borbas, have you checked into what is required to import an automobile from the USA to Canada?

I quickly looked on WiKi. There are things like:

* Must be on Transport Canada’s list of permissible makes and models.
* Contact the Registrar of Imported Vehicles (RIV) and Transport Canada about any potential modifications.
* Purchase Canadian car insurance before you import your car to Canada.
* Obtain a “Proof of Recall Clearance” from your car manufacturer.
* Contact US and Canadian Customs.
* Take your car, Form 1, and Form 2 to an RIV inspection center (in Canada).
