It is a vast question.
On the grain shipments, most of the grain will be exported in bulk cargo, so your typical route will be going either west or east. In the case of the Great Lakes and St. Lawrence, the cargo will be moved by train, let's say to Thunder Bay. From there, it will be put on a laker and brought further east for export. Most of the grain in the country is being exported.
In that regard, the seaway has a capacity right now at about 50%, so we could double the number of ships crossing the seaway today without much impact on traffic. That's certainly something we could do, although manning vessels and manning them in the future could become a difficult thing to do.
