Grain elevators in Thunder Bay are soon going to burst at the seems now that the Harper government has ordered the railways to ship prairie grain ASAP. Tim Heney of the Port Authority says shipments should be coming through here in about a week or so. Heney says there's room for about a million tons of grain so when it starts arriving it will be a big bonus. He says it's always good to have plenty of grain in storage so that when the shipping season starts, there will be enough to fill the boats when they arrive.
