If it refers to the general consumption tax, then when buying something in Quebec, you need to pay a federal tax of 5.05 and a Quebec provincial tax of 9.975, for a total of 14.975. For example, if you go to a store to buy a product priced at 100 yuan, you will have to pay 114.98 yuan at the final checkout. If you pay with a credit card, the amount is 114.98 yuan; if you use cash, because Canada stopped using 1-cent coins two years ago, the settlement is based on "rounding up to the nearest 0 and 5 (the mantissa is rounded up to 1 or 2, and 3 or 4 is rounded up) 5, 6 or 7 is rounded to 5, 8 or 9 is rounded to 10)", so you have to pay 115 yuan.
