The Foreign Trade Zone (FTZ) qualified Port of Ogdensburg provides large sea vessels with access to the Great Lakes and world ports.

The Port of Ogdensburg is the first U.S. port of call when entering the Great Lakes & St. Lawrence Seaway System, providing the ideal location for inbound shipments of cargo for delivery to the United States and Canada. The Port’s strategic location, combined with its trouble-free multi-modal rail and highway connections to all points in North America, makes it highly economical for ships to deliver cargo to the Port for distribution to the U.S.A. and Canada.

Exporters have also discovered that the Port of Ogdensburg is a prime location for outbound shipments to Europe and other overseas locations. Because the Port is closer to Northern Europe than most U.S. ports, transportation costs can be reduced by using the Port of Ogdensburg. Product can be easily railed or trucked to the Port of Ogdensburg for overseas shipments.

The Ogdensburg-Prescott International Bridge is located less than three miles (4.8 km) from the Port and is the principal artery in the region linking the U.S. and Canada.

The St. Lawrence Seaway

The St. Lawrence Seaway System is a 3,700 km “marine highway” that extends from the Atlantic Ocean to the Great Lakes connecting the lower St. Lawrence River to the Great Lakes and enabling ships to transit between Montreal and Lake Erie.

Miners, farmers, factory workers and other commercial interests ship goods from the western prairies to the eastern seaboard. Over 200 million tons of cargo travel on the waterway on an annual basis.

The Seaway serves as a key supply chain for the Great Lakes Region – the world’s 3rd largest economy. And with economic output estimated at US $6 trillion in 2017, the region accounts for 30% of combined Canadian and U.S. economic activity and employment.

Gross Domestic Product

(US $ trillions)

The Great Lakes–St. Lawrence region boasts a massive geographic footprint, and is a major driver of the North American economy. With economic output estimated at US$6 trillion in 2017, the region accounts for 30% of combined Canadian and U.S. economic activity and employment. The region’s output ranks ahead of Japan, Germany, the U.K. and France, and it would rank as the third largest economy in the world if it were a country, behind only the U.S. and China—notably, the region overtook Japan a few years ago. Quite simply, the economic importance of the region can’t be overstated.1
