To my way of thinking, there are two parts to the seaway. One is the lower lakes and one is the full route all the way to Thunder Bay. And grain is the only option in Thunder Bay at this point. We have coal and we have potash to smaller degrees, but in its history, grain has been the mainstay. So without the critical mass, as you say, in grain, you could eventually lose the capability of the seaway being a link to western Canada. In other words, a route that travels 2,300 miles inland is sustained basically by grain.
We still have nine elevators. That's far more than is theoretically required and that's sustained by the diverse ownership of those elevators. But certainly we're at the lowest. The last five years have been the lowest five years in the history of the port and grain. How much lower can it go? It's always a question. We don't know. You will start to see elevators lost during consolidations of companies. Beyond that, it seems to be sustained by that distinct ownership.
