I'll be very quick.
With respect to market access, there's an economic rationale that remains very relevant for existing production even outside the question of expanded production in the oil sands, and that is to alleviate the sale of Canadian petroleum products at a discount from market value.
At the end of the day, resources in this country belong to Canadians writ large. For too long, oil has been sold at a discount. The underlying economic rationale is to curtail that discount and actually get a fair market value for the energy resource that is developed, and bring that to market in a responsible way.
