Please excuse the topic drift!
Our number plate /vehicle registration is very different system and only our military have Canadian number plates, each Province issues their own, totally different plates completely, (most provinces only issue a rear plate) issued to the car owner and stays with that owner and not the vehicle, each year a fee is payed for a year/ month sticker, that is all you can affix to a plate.
Two of my vehicles have personal plates and two have vintage plates, I used to have the Northumberland red yellow stripped flag/ bumper sticker on one truck.
