Thanks for your attempts at candour. I understand the constraints.
I just want to share that a gazillion years ago, before I was in politics, I actually participated, with Sierra Club Canada, in the environmental review of the Kearl Lake proposed mine. I clearly remember Imperial saying that it was state of the art for tailings ponds management, with no need to worry about leaks. I remember that when Dr. David Schindler started documenting the leaks, his reputation was attacked.
In hindsight, did the environmental assessment process get to the truth, or were we sandbagged by industry?
