I'll answer your question on the output-based sector, as far as the refining sector goes. It is impacting our sector. You're right. The United States does not have any carbon pricing, and we do. I think we need to look at the carbon border adjustment, for example, to make sure both what is Canadian and what is coming into the country are protected.
I think we need to maintain the provincial leads on this, because they have a lot of regional programs that support regional differences. So far we are doing that, but we're not sure yet where the benchmark is going to land, to be honest with you. We're a huge proponent of leaving the provincial systems in.
