I can't really talk about the system in Quebec because I'm not familiar with it. What I can say is that under this regime, the fuel distributors are the people who are going to pay the charge. The fuel will be paid, if it's delivered in a listed province—a listed province being a jurisdiction that will be listed in part 1 of schedule 1.There are rules for bringing in fuel to a listed province from another place in Canada, and in that case, the fuel charge under this system would apply, but there are also rules for relieving when the fuel is removed from a listed province to go somewhere else.
