What does the GLS do?
The Great Lakes St. Lawrence Seaway Development Corporation (GLS) is a wholly owned government corporation created by statute May 13, 1954, to construct, operate, and maintain that part of the St. Lawrence Seaway between the Port of Montreal and Lake Erie, within the territorial limits of the United States. Trade development functions aim to enhance Great Lakes/St. Lawrence Seaway System utilization without respect to territorial or geographic limits.
The mission of the Corporation is to serve the U.S. intermodal and international transportation system by improving the operation and maintenance of a safe, reliable, efficient, and environmentally responsible deep-draft waterway, in cooperation with its Canadian counterpart. The GLS also encourages the development of trade through the Great Lakes Seaway System, which contributes to the comprehensive economic and environmental development of the entire Great Lakes region.
The GLS headquarters staff offices are located in Washington, D.C. Operations are located at the two U.S. Seaway locks (Eisenhower and Snell) in Massena, N.Y.
