Hi, I’m Federick William. I have ordered paddle shifters from Ebay for my car. I’ve bought it for approximately 402$ CAD and I’m charged with 100$ duty and import taxes. The Ontario tax calculator is useful for estimating the import taxes. As I’ve selected the option for the Province and it estimated that I should pay 60$, so I’m not sure why they charged me an extra 40$. This Canada tax calculator is a free tool for accurate calculations.    https://hstcalculator.onl/
