Yes, I think they are. But the other side of it that you need to keep in mind is, at least in the industry as it stands now, when a new mine is opened, it's opened after a regulatory process that approves the plan of how that resource will be developed, how the tailings will be managed, and how the mine will be closed. The opportunity in terms of regulation and public discourse is essentially at the stage when a mine project comes up for approval. When it's approved, that's essentially a contract between the regulatory agencies and the companies that then governs how that particular lease will be developed over the course of its life.
If I look at the history in Alberta, you can't rewrite the book with a company. My personal feeling is that you can't try to change the rules once the company has done half of its plan. The plan that Syncrude filed, for example, was before it opened its mine in 1978. They laid out, based on the technology of the day, what they were going to do with the oil sand and how they were going to reclaim the mine site, and they're proceeding with that reclamation process.
