Thanks again to all of you for being here today.
I want to start with Mr. Reynish again. You mentioned a carbon tax and the Alberta climate action plan. I wondered, assuming a broad-based carbon tax across the continent at least, what kind of tax do you envision? For instance, would it be a revenue-neutral tax or something that would go to fund innovation? How high a tax would be needed to drive the market toward something where we would be meeting our COP21 commitments, for instance?
