On the issue of jurisdiction, I know none of you are lawyers—that's great—but the issue around the federal jurisdiction to establish a backstop is a central one, and it's going to be played out before courts of appeal in Canada this year and likely next. How important is it to have judicial clarity around the federal government's jurisdiction in order for a pricing mechanism to be effective all across Canada? I ask each of you, anyone who is interested in getting into that issue.
Maybe I'll put it differently. What are the negative repercussions of the inability to have an equally imposed price on pollution across Canada, a baseline, if you will?
