Maybe I'll just very quickly say that, regarding carbon pollution—the carbon pricing issue aside—we are working with these companies in innovation. There was a budget 2016 program called the oil and gas clean technology program and we now have—I referenced it in my speaking notes—the clean growth program, which we've just launched. In both programs, as well as in work that NRCan does in its CanmetENERGY laboratories, we work to look for innovative opportunities to lower the cost of environmental technology through clean technologies in the context of the oil sands, as well as all of the other natural resource production sectors.
I will pass it over to you guys.
