Really?
Oh not here. License plates are ready and waiting for you when you pick up the car.
You can swing by the DMV today and walk in and buy a set of plates. If you want personalized plates obviously it has to be ordered.
I had plates from my previous car so the dealer just swapped them, but when my brother just bought his car he didn't have plates; when he picked up his Sentra there were new plates on the car just waiting for him, with the stickers and everything.
I don't think I have ever seen a temporary tag here on an Ontario car.
