I'm going to respond to the first part of the questions and then pass it on to Carol for the details.
In terms of the approach that we're taking with the provinces and territories, I have been working with the provincial environment ministers, as well as territorial environment ministers, in addressing ways of going forward in how we contribute to the reductions of greenhouse gas emissions in Canada. I have also stated that they have provincial levers as well. They need to do their part, we need to do our part, and we're committed to doing that. The provinces and territories have their own targets. They establish their own targets and their own initiatives, and that's great because they do need to do their part, and so do we.
The federal initiatives that we have undertaken have been a sector-by-sector approach, and those are our contributions to reducing greenhouse gas emissions, as well as other investments in clean energy technology and so forth.
We'll continue to work and engage with the provinces and the territories. I'll be meeting with them in Winnipeg in June. I also met with the Quebec minister, as well as B.C.'s, Alberta's, and Ontario's when we were in Lima in December at the conference getting ready for the actual discussions in Paris next year.
With that, I'm going to pass it on to deal with the issues of contaminated sites—
