The area that concerns us the most with overlap—I wouldn't say “overlap”, but integration—would be how the proposed carbon pricing is going to work between the provinces and the federal government.
We've spent years working with the federal government on an approach that we thought was going to work. We've spent years working with the provinces. Ontario is going down a cap-and-trade route, as is Quebec. B.C. has a carbon price. Alberta has an approach that's a hybrid, with a carbon tax plus regulatory requirements and performance standards. There is a concern that just as we are coming to grips with how those are going to work and how we can make our own contributions within those systems, there is something else on top. How the federal efforts will work with the provinces is a key point of concern for us at this time.
When it comes to other issues, we've worked very closely with the federal government as well as all stakeholders and the provinces on the federal clean air agenda—also over the last 8 to 10 years—and, by and large, that has been successful. It has been successful because people have come to the table and identified what the correct role for the different parties is.
