If you buy another car to replace your broken-down one, you have up to 10 days after buying that car to visit an Autoplan broker and transfer coverage on the vehicles. During that time, you can use the old plates (as long as it’s the same type of plate—for example, you’re not attaching passenger vehicle plates to a commercial vehicle).
If you still own the broken-down vehicle, you’ll have to visit an Autoplan broker to transfer the licence and insurance before you can move the plates to another vehicle.
Tip: if your vehicle won't be used for a while, you may want to ask your broker about buying storage insurance. It helps protect your vehicle even when it's not being driven.
