Let me just clarify that. The study we did a while ago on climate change and the impact of a tax actually did not come directly from us. It came from the round table on the environment and the economy, and it was based on a hypothetical situation.
Concerning the current announcement the government made on the tax it's planning to impose, we don't really have enough information on exactly how that's going to work out. It all depends on how the provinces are going to react to this and how they're going to recycle the money they're going to receive from this. With all that information, then we can actually sit down and measure the overall impact of that change. Right now it would be very difficult to actually pinpoint a number and say what the impact would be.
