I have further questions, but I thank you for that.
We can't forget that these trade corridors operate with neighbours. There are residential areas. There are commercial areas. One of the sticking points on the west coast, for instance, is the capacity used by the West Coast Express commuter rail, which of course significantly reduces the capacity for freight movement on CP's lines.
Looking at that combination of local needs and local relationships versus—obviously—the bigger trade picture, I'm just wondering what Transport Canada's view is of things like commuter rail and the future for commuter rail, if in fact the country starts to build to the capacity and the promise of the trade agreements and to have more trade going in and out of our ports.
David, maybe that's a question for you.
