thanks for the link. I found this.
Returning Canadian vehicles are exempt from the Registrar of Imported Vehicles (RIV) program when former residents of Canada bring the same vehicle that they exported to the United States, back into Canada. The following conditions apply:
(a) the vehicle was certified by the original manufacturer to comply with the Canada Motor Vehicle Safety Standards (CMVSS);
(b) the individual can substantiate that the vehicle was purchased or registered by him/her in Canada prior to departure;
(c) the vehicle did not undergo substantial modifications or alterations while abroad; and
(d) the vehicle has not entered into commerce (sold, traded or leased to any other party).
Individuals will be required to show proof to the Canada Border Services Agency (CBSA) that they owned the vehicle while in Canada, when they import it back into Canada.

what does it mean when it says the car is exempt from the RIV program? show up at the border with necessary docs that all conditions are met and we are set to go?
