I'll just ask this of Dr. Moore. We've heard a lot in this committee over the past few weeks about innovation and how we need to foster and incentivize that, especially in the oil sands—as Professor Elgie was saying—to help our environmental reputation as well as, hopefully, reducing costs. However, we heard from COSIA that the new innovations they were working on—some of which are very exciting—were only going to be played out in new oil sands projects. The ones that are already extant would not generally use them. Now we hear that the new oil sands projects are constrained by low oil prices around the world.
I'm just wondering if you have an opinion on what oil price would get these projects going again.
