In 2014, as we had the order in council, CN committed under the order in council to move x tonnes of grain on a weekly basis. Obviously, when it came into effect in March of 2014, the weather broke two weeks later, and all the grain was moved before the end of the crop year. We use this argument at CN: press releases don't move grain; people and our locomotives do.
On March 19th, 2018. See this statement in context.
