The oil industry is part of a world market. So, if there are additional costs for the oil sands sector, the world price will not change. An increase in costs would mean that these projects would no longer be viable, but that will not happen. It's a question of balancing the security of supply in Canada and the cost-effectiveness of these kinds of projects, depending on the result of additional costs for greenhouse gases.
If these projects were not cost-effective, there would not be as much development occurring today. However, our balance, in terms of supply and demand in Canada, would mean that we may be subject to imports.
This is a very important question for the country and for the federal policy.
