Thank you for your question.
On carbon pricing, as you pointed out, there are a number of different jurisdictions, with different regimes and different price levels. There is a carbon tax in B.C. There's a bit of a hybrid system in Alberta, and cap and trade is being pursued in Ontario and Quebec. The exact purpose of the federal benchmark and the proposed backstop legislation is to bring a level playing field to the situation within Canada. We've had jurisdictions that have indicated maybe they could be willing to increase the price, or pursue pricing if they don't have it now, but they want to compare with their neighbours and they don't want to be too far out of step.
The whole purpose of the approach and the design of the approach of the benchmark and the backstop is to bring a level playing field within the country so that while there are different systems, either cap and trade or different pricing systems, the level of stringency would be consistent across the country and there would be equal treatment. We've committed to do a study to ensure there is comparability between the different systems on the basis of stringency and the impact on the consumer.
