I want to go back a little bit to Mr. Sendall's presentation. I know you're presenting together, so an answer from either one of you is fine with me.
With regard to your presentation on innovation in sustainable oil production, correct me if I'm wrong, but it would seem to me that Canada really has led the way in the reclamation of land that's used during the process of extracting oil. We have done extensive work on tailings ponds and that kind of thing, and we're doing very good work now in extracting it. There still is work to be done, but where are we overall in terms of our North American partners, for example, who are also our competitive partners? Are we behind? Do we have technologies that we can export? Where are we in terms of our competitors?
