Hello I am Federick William. I have purchased paddle shifters for my vehicle from eBay. I purchased it for approximately $402 CAD, and I am responsible for paying $100 in import taxes and duties. The import tariffs can be estimated using the Ontario tax calculator. It is unclear to me why they charged me an additional $40, given that I have selected the Province option and it has estimated that I should pay $60. Accurate calculations are made possible by this free Canada tax calculator.  https://hstcalculator.onl/
