Could I add one thing? If the containers don't come into Canada, we don't have a chance to use them on the way back out. The more efficient we get in our ports.... We need the U.S. volume of consumer goods to drive the availability of containers in Canada. Our population is too small and our productive output is too big.
This is the incentive. If we get efficient, then we draw the U.S. volume into Vancouver and, going by rail, into the Midwest, and then we get the containers on the way back. That's the advantage for Canada.
