I think it's correct to say that the working group did not define what high means. There's probably more work to do there. As my deputy mentioned, there are a number of tools that allow us to see through what is happening in the grain handling system, from inland terminals right to port. Some come through the CGA, the Canada Grains Act. Some come through the Canada Transportation Act. Some come through our fairly extensive interaction with the industry.
We have a grains industry round table that meets regularly. We have value-chain round tables that bring in other dimensions of the grain industry so that we can see what's happening, and we have a ten-year program and partnership with Transport Canada to monitor, in a very detailed way, the performance of railways in delivering grain to port and then turning around. There is some work to do on how high is high, but we think we have the tools to help us see through that and decide when there are problems and to intervene.
