Grain shipments are down as cargo traffic on the St. Lawrence Seaway lags last years totals through October.
But iron and coal shipments are up substantially this year.
Grain shipments through the Montreal-to-Lake Ontario section declined to 5,711 thousand metric tons this year, down from 5,950 thousand metric tons through October last year, according to figures compiled by the Great Lakes St. Lawrence Seaway System.
Iron ore shipments have risen from 6,451 thousand metric tons through October last year to 8,491 thousand metric tons this year, up more than 30 percent.
And coal freight has risen from 1,030 metric tons last year to 1,833 metric tons through this October, up 78 percent.
The Seaway will be closing for winter at the end of December.
