If it's a federal fine under a federal act, then, of course, the money goes back to the federal Crown. If it's a provincial fine, then it would go back to the provincial government. If the judge orders restitution or some kind of other monetary penalty, then that would go to the jurisdiction that is responsible for the act. The only difference, sometimes, is as with impaired driving, theft or something like that. It would stay within the province, but anything to do with drugs, illegal tobacco or fisheries would go back to the federal government.
