Going back to the Canadian Trucking Alliance, again, there's a lot of integration between Canada and the United States. There are a lot of trucking companies that operate in the United States; they come to Canada and vice versa.
What are some of the competitiveness differences when you have no carbon tax in the United States? Are we going to be seeing trucking companies just simply filling up right on the border and then coming into Canada, where maybe before they would fill up on the Canadian side? What are the kinds of distortions that may happen there?
