Interesting how the provincial tax system works in the rest of Canada. My opinion is it should be set up the same as the GST. Once the taxes are paid on an item once, it should be free and clear of future taxes. One more reason I'm glad to live in a province with no provincial sales tax. JMO.The real winner in all this are the governments that collect HST on every transfer of ownership. They can collect more in total taxes on a car than the MSRP of the car itself...
