I think I'll defer the question on who is best positioned to look at that and whether it's the commissioner of the environment. However, I would say that ECCC does conduct routine inspections to check for seepage from oil sands tailings ponds throughout the Athabasca regions. We respond to any releases that occur in contravention of the Fisheries Act and we will be conducting some additional inspections this year. For the last 10 years or so, we have collected hundreds of samples from various tailings ponds to ensure compliance with the Fisheries Act.
I would also say, in terms of the risk that you have mentioned, that we are working right now with a Crown-indigenous working group to look exactly at options to address the risk from the accumulation of oil sands processed water in tailings ponds, recognizing that this does pose an important threat to nearby communities.
