So then if we see the standards are consistent and we see the cost here in North America go up because of these new standards, are we going to do something to make sure other countries around the world would come up to those standards? What does that look like? I know there's been talk about a border adjustment type of tax on pollution. Do you see us doing that in harmonization with the U.S.? If that's the case, what does that mean for Ontario, Quebec and eastern Canada, which bring in so much oil outside of Canada?
