so that means I, as a seller, don't have to pay the sales tax. and still can sell it as BC registered car?
Yes, that's what it means.
The MTO (Ministry of Transportation of Ontario) doesn't care if or where a car is registered on the seller side. All the MTO cares about when a buyer goes to register a new/used car is:
- does the car have the proper safety and emissions certificates
- does the buyer have the ownership signed over to him/her and (preferably) also have a bill of sale
- has the buyer paid the 8% PST
- does the buyer have a valid driver's licence and proof of insurance
That's it, that's all. In your case as far as the MTO is concerned it doesn't matter where the car was registered prior to the buyer coming to register it after the sale.
