The latest statistics from the St. Lawrence Seaway show that grain shipments are up more than 20 percent as the marine highway benefits from international demand for American and Canadian wheat.
Year-to-date grain shipments from March 22 to June 30 totaled 2.6 million metric tons, compared to 2.1 million metric tons during the same period last year.
