Gulf of Saint Lawrence

The world's largest estuary is the Gulf of Saint Lawrence; it is a partially-enclosed sea and is the outlet of North America's Great Lakes through the Saint Lawrence River into the Atlantic Ocean. It covers an area of approximately 236 000 km2 and it contains 35000 km3 of water.


The gulf is surrounded by the Labrador Peninsula on the north, by Newfoundland to the east, by the Nova Scotia peninsula and Cape Breton Island to the south, and by the Gasp� and New Brunswick to the west. Anticosti Island, Prince Edward Island, and the Magdalen Islands are some of the islands. In addition to the Saint Lawrence River, there are Miramichi River, the Natashquan River, the Restigouche River, the Margaree River, and the Humber River.

The gulf flows via the Strait of Belle Isle between Labrador and Newfoundland into the Atlantic.

Cultural importance

Traditionally the gulf is an important marine fishery for various Nations that lives on its shore for millennia and used its waters for transport. The five regions bordering the gulf also have various regional parks, some of which protect coastal features.
