Uber's fares are not fixed by the licensing authorities. Therefore, if anyone took an Uber ride today, the fare is calculated on distance and by a multiplier, depending on if there's surge pricing or not. It all depends on demand. They should be adding the HST to the final fare, as we are adding it. The difference between us and Uber is that we have to include it in the metre, whereas they can easily simply add that to their calculations when they remit the invoices or the receipt to the customer.
