As a member of the Bloc Québécois, you are in a good position to know that, under the Canadian Constitution, natural resources are a matter of provincial jurisdiction. You mentioned it in your introduction. So the federal government can't tell a province that it can't use its oil, just as it couldn't tell Quebec that it can't use its hydroelectricity. It's the same thing. Provinces are sovereign in the use of their natural resources. However, the federal government can and must take action on pollution, and it is doing so.
