There can be no doubt that it's possible to evolve. We move a lot of products, some of which have higher value-added, and others are in larger quantities, as you said, in efficient unit train cycles.
Will the railways be able to follow the agricultural sector's evolution toward new types of production? Will that mean that more grain will have to be transported in containers? Will that mean that other innovative methods will have to be used to meet demand? We don't know all the answers to these questions, but there can be no doubt that we'll be able to rely on the agricultural sector in all Canadian provinces as a whole in the same way we move containers of very high value-added products from Asia or Europe.
