St. Lawrence River

The St. Lawrence River is known as "Le Fleuve," the Greatest Canadian River, and we are fortunate to have it flowing past our community here in Leeds Grenville.

Aerialview.jpgIt's both a trade corridor as well as a recreational waterway attracting millions of visitors to its waters and its scenic 1000 Islands every year. The river stretches more than 306 kilometres (189 miles) from Montreal to Lake Ontario at Kingston, part of the interior Great Lakes. Here in our area we have a front-row seat to where the St. Lawrence swirls around more than 1,800 large and small islands.

It's considered one of the world's greatest and most strategic commercial waterways with a top-notch safety and reliability record. It was built as a binational partnership between Canada and the United States. Administration is shared between the Canadian St. Lawrence Seaway Development Corporation and the U.S. Saint Lawrence Seaway Development Corporation. Thousands of pleasure craft transit the Seaway locks each year. Valuable boating information can be found at including The St. Lawrence Seaway Pleasure Craft Guide by the St. Lawrence Seaway Management Corp.

There are marinas providing various services in the communities of Johnstown, Prescott, Brockville, Mallorytown, Rockport, Ivy Lea, Lansdowne and Gananoque.
