I'll start by answering your last question. The Canadian Transportation Agency determines car maintenance costs. It's the Agency that requires maintenance changes.
I'd like to clarify if I may, Madame, what I said earlier. I mentioned that there are approximately 12,100 cars right now in the federal hopper car fleet. Originally there were about 13,000 cars, and over the course of the last few years, as cars have proved to be unsafe or in really poor condition, they've been withdrawn from the fleet.
We have safety inspectors in Transport Canada who are very vigilant about what is safe to operate on the railways, and they work with the railways themselves on those issues.
We are not, at the moment, looking at replacing the cars, but we will be talking to the railways about a new operating agreement for the management of the existing 12,100 cars, and also about issues related to how those cars will be maintained in the future. That will include setting up a monitoring system to make sure that as those 12,100 cars continue to be operated by the railways, the railways are keeping them to the standard that is established throughout North America by the Association of American Railroads.
