In Canada and in US absolutely. They are not allowed to discriminate based on destination, length, let alone race, etc. Nevertheless, I take taxis many times a week for work in Ottawa (Canadian Capital), and they regularly refuse rides they deem too short or too long (or, grudgingly accept them and complain or yell the entire time). This is #1 reason I've used Uber last year, because it's a more civil, pleasant, safe experience (work covers expenses so cost is a non-issue, and Taxi would in principle be more convenient as they're waiting at the hotel).
