Unifor has reached a tentative agreement with St. Lawrence Seaway Management Corporation, ending a weeklong strike that halted shipping along the route. An agreement was announced at the start of this week following mediated negotiations on behalf of Ontario and Quebec members. St. Lawrence Seaway Management Corporation CEO Terence Bowles says, “We have in hand an agreement that’s fair for workers and secures a strong and stable future for the Seaway.” The tentative agreement covers roughly 360 Unifor members in Ontario and Quebec, who work in the supervisory and engineering group and the maintenance, operations, and clerical group. Specifics of the agreement were not released, but workers did return to work Monday morning. The Great Lakes-St. Lawrence Seaway is a deep draft waterway extending 2,300 miles from the Atlantic Ocean to the head of the Great Lakes at Duluth, Minnesota. The Seaway includes 15 locks – 13 in Canada and two in the United States.
