IMPORTATION OF VEHICLES (15) YEARS OLD OR OLDER AND BUSES MANUFACTURED BEFORE JANUARY 1, 1971 - Vehicles fifteen (15) years old or older, as determined by the month and year of manufacture, and buses manufactured before January 1, 1971, are no longer regulated under the Motor Vehicle Safety Act by virtue of their age. While Transport Canada does not regulate the importation of these vehicles, it does not preclude the vehicles from having to meet provincial/territorial safety and licensing requirements. Importers of such vehicles are required to complete a Vehicle Import Form 1, at the time of importation, and present proof of ownership. Also, please contact the Canada Border Services Agency (CBSA) for clearance requirements.
