Mr. Chairman, I will answer in general terms, and then I'll ask Mr. Brazeau to add to my answers.
The first one is looking at the toll rates in the greater Montreal area. Two autoroutes, the 25 and the 30, are toll roads. We are looking at the way the toll system is working there, and how the rate was established.
With respect to the second part of your question on revenues, the Government of Canada will retain all the risks relating to revenue. That means we will make payments to the private partner, but the private partner will not assume the risk based on volume.
With that, I'm going to turn to Marc so he can add to the answer.
