In Quebec, when buying through accommodation , you have to pay both taxes. Now what I do is reduce the price by 5% for the gst , that you would not have to pay, if you bought directly from me. You still get a lot more, for your vehicle, than trading it to the dealer. Dealerships did not like that because they were losing money, so they started charging a ridiculous amount , 500$ to 750$ for paper work that they used to do it for free. It takes 10 minutes , maybe . We are getting taken by banks , car dealers, etc. for things we used to get for free , that was called customer service but now paying full price, for lots of things , is still not enough for these .....
