Thank you for your question.
I think you're referring to recent stories about tailings ponds in the oil sands that have not met provincial targets. Of course, as you know, we work with the Province of Alberta too, and we're at the moment crafting regulations for the oil and gas sector, including the oil sands sector, to cover the range of environmental concerns.
We're in the second year of the process of implementing the joint Canada-Alberta oil sands monitoring plan, which was designed by scientists at arm's length. It is being implemented transparently and will address exactly the sorts of issues you raise.
There are certainly challenges in the continuing development of the oil sands, whether with regard to tailings ponds, with regard to water use, or with regard to emissions and emissions intensities. But I can assure you that the Government of Canada is well focused on effectively regulating, with the cooperation of the sector and the provinces and the industry, outcomes that are more environmentally appropriate.
