Mr. McCallum, the point you made hit the nail right on the head. The interpretation of it is left wide open. Certainly some would argue, and it's an extreme example, that the highest level of safety is attained by not moving a train.
What we're really looking for is, first of all, consistency. It's in the Canada Transportation Act, which Mr. Mackay alluded to. The standard for highest practicable level of safety is understood, because it's in another piece of legislation. It incorporates the inherent nature of a railway operation, which is that you will be moving trains. Within that, the safety management system requires us to manage the associated risks.
That's the reason, really, for our position. I certainly appreciate your comments.
