Yes, that's a great question. A lot of the time people will think, Saskatchewan is basically on the west coast, so you'd ship out of the west coast. In fact, it's still quite a distance to go through either Canadian or U.S. ports on the west coast. In shipping to the east coast, CN has been able to put a program together to ship longer trains. They've established some economies of scale that were very helpful to Canpotex, the shipper in this case. It's really worked very well, particularly for the fact that a lot of the destinations are on east coast, South America, so in Latin America, either Central or South America. If you're going to Brazil, it's one thing to consider what the origin is, and then another to consider what the destination is, and just their volume altogether. They have ready infrastructure and a terminal here in the Port of Saint John. The business has worked very well.
In 2017, as I mentioned, we actually saw our biggest shipment year ever of potash exports. Obviously, it's working pretty well.
