Certainly, we have looked at that hard. As you know, we have a number of jurisdictions in which we operate, primarily in Alberta, British Columbia, and Saskatchewan, that have a variety of different instruments where we value carbon and do activities related to that. There's been, for example, in Alberta quite a significant amount of work on GHG reduction mitigation policies. There has been a carbon tax imposed there. There are also other costs related to that regulatory, as well, based on a value of those emissions.
British Columbia, as you know, has a carbon tax that has been in place for quite a few years now. Saskatchewan for its part has done a lot of work on investing in technologies related to carbon capture and storage. I think the first thing I would tell you is that our sector is not ill-prepared for dealing with and working in this kind of environment. I think, as we proceed and we go beyond at the upper ends of the announced price that we see, there would be a need to look hard at what that means for the competitive environment for investment and trade with other nations, and primarily the United States, which does not have anything near the stringency that we have in Canada on this issue.
