Thank you, Ms. Chatel.
If I may, I'd like to direct the remaining time—I think I have about three minutes left—to Monsieur Charlebois.
Monsieur Charlebois, just going back to the prior exchange with my colleague, you were talking about the price on pollution and the fact that there are price-takers in the value chain. You were also talking about the fact that you wanted to study what the impact of the price on pollution, the carbon tax, would be on end-consumer prices or whether there is one. That suggests to me that you're not sure if there is an impact on end-consumer prices by the price on pollution. Is that correct? If you knew, you wouldn't need to study it.
