After you buy a car you get the plates. Thery're not tranferable.
Shouldn't take more than 30 minutes to do all that at a MTO office.
You don't care if previous owner's plates are valid or not, just make sure the
car is certified.
At any MTO service or kiosk location you can obtain UVIP (Used Vehicle Information
Package) which provides history of a vehicle, usually provided by seller.
Take a letter from your current insurance company as a proof that you had
no claims for certain period of time. Some companies here may accept it.

recognize your driving record but for the best quotes, you should shop when you
know what car and year you'll buy.
