Okay, thank you very much. I thought that was very interesting testimony, and it's something that has not come up. You're the first to mention it, but I think it's extremely important for us to consider as a committee.
Second, Madame Tremblay and Monsieur Plamondon, coming back to this issue of the differential, the companies that are involved in value added aren't suffering from the differential. Husky and Suncor are two examples. Isn't that really a solution, ensuring that we get full value of the resources by making sure that we're doing value-added upgrading, refining and petrochemical here in Canada?
