Thank you.
I'm going to turn to Professor Heffron.
You talked a lot about the importance of a just transition, justice in all these stages. When we're talking about critical minerals and the mining industry in Canada, I think Canada's come a long way in the last 50 years or so in terms of that concept of justice in the extraction of minerals. There's been a lot of progress made on those fronts.
Where we seem to be lagging is decommissioning, a topic that you mentioned. We've had some real horror stories with the decommissioning of some mines. There's the Giant Mine in Yellowknife, which seems now to require investment by this government, the federal government, for eternity to keep it from poisoning the area further. We have the situation of oil wells across western Canada that some companies have set up when they're going into receivership. They set up situations where that fiscal responsibility falls on the government.
I'm wondering if you have any best practice models of policies from somewhere else in the world that have really worked, that have ensured that the cost of decommissioning is put on the project and the company, and not treated as some externality for the public purse to clean up at the end of a mine or oil well's life.
