You can pay for the car and still lose it at the border if the paperwork, the factory configuration, or the inspection path does not line up. That is where people get caught.
Transport Canada routes regulated vehicles from the United States through the Registrar of Imported Vehicles process. The vehicle has to meet a federal standard before it is admissible in Canada. If it was altered in a way that changes its original factory certification, it can be refused even after a legitimate purchase.

The starting point is eligibility. Under subsection 7(2) of the Motor Vehicle Safety Act, some U.S.-purchased vehicles can enter Canada if they were originally built to meet applicable U.S. Federal Motor Vehicle Safety Standards and can be brought into compliance with Canadian Motor Vehicle Safety Standards. Not every U.S. model qualifies. Some are barred from the start.

Age can remove a vehicle from the regulated process. Vehicles manufactured more than 15 years ago are exempt from MVSA compliance at importation, and the same applies to buses manufactured before January 1, 1971. CBSA entry requirements still apply. Only the federal safety test changes.

Do not assume a modified vehicle can be corrected later. Transport Canada says a vehicle that has been modified beyond general repairs or routine maintenance no longer keeps its original factory-issued certification. That includes a motorcycle converted into a trike, a cargo van turned into a camper, a suspension lift kit, a disability-access conversion, a lengthened vehicle, or a body kit installed after manufacture.
The certification is the anchor for the import process. If the final stage manufacturer or modifier has not established compliance with Canadian standards, the vehicle cannot be imported on that basis. The same rule applies to Canadian-certified vehicles that were modified in the United States and then brought back.
Transport Canada also publishes a compatibility list for vehicles purchased in the United States. Useful does not mean guaranteed. A model can appear admissible for the RIV program and still fail later if the vehicle does not match the documents or does not pass inspection.
In practice, this matters far more than the formal language suggests. A clean listing on a compatibility chart does not rescue a car with the wrong modifications.
