I can speak best for up north. I'm from Yellowknife. I live in Yellowknife. It's on Great Slave Lake. It's been factually documented that there are toxic chemicals coming from the tar sands south of us, which include arsenic and other contaminants. They're coming from the tailings ponds that have been there for many years.
One of the things you might want to look at is to eliminate those tailings ponds. It would take some money from the federal government, the provinces, and industry so that you get rid of the tailings ponds and then you get rid of the leaching that occurs. It's real. It's happening.
It happens all over the country. The problem is, water moves. Our scientists will tell us it's difficult to tell you exactly where it begins and where it ends, but it is possible if you invest.
