In Ontario, license plates move with the owner, not with the vehicle. If you sell or change vehicles, you keep the license plates and put them on your new vehicle. If you are not going to use your old license plates, you can return them to a Service Ontario center.
You should also transfer the vehicle permit or the ownership of the vehicle to the car scrappers. Vehicle ownership includes the following information:
The Vehicle Identification Number (VIN)
The make and model of the car
The name and address of the vehicle owner
The plate number that is attached to the vehicle
The smaller part of the license plate validation sticker
