I can add to that, just to put a finer point on it. Effectively, some of the proposals—there's more than one in the United States—would fund a tax cut in the United States through a border adjustment tax, which could place a tax of anywhere up to 20% on everything that we send into the United States and back seven times. That would be a very severe constraint to the ability to win new investment for anything in Canada that depends on the United States market. If you put on a 20% cost, you don't have a margin left.
It would be something that one hopes is not contemplated. I think it would be something that is also problematic in the United States in various ways, let alone trying to understand how it would ever be calculated in the kind of integrated business that we're in.
It's challenging, but one hopes that this moves forward without that aspect.
