Hochelaga Archipelago

The Hochelaga Archipelago, also known as the Montreal Islands, is a cluster of islands at the confluence of the Ottawa and St. Lawrence rivers in southwestern Quebec. It is estimated that the archipelago comprises about 300 islands and islets, of which the Island of Montreal is the largest. Like the Island of Montreal, the other three largest islands — Île Jésus (most of the City of Laval), Île Bizard and Île Perrot — are inhabited, while most of the smallest ones are not. Several of the islands that comprise the archipelago are protected by the Nature Conservancy of Canada. Though not originally part of the island chain, Île-Notre-Dame is a man-made island within the archipelago, and today is home to Montreal’s Parc Jean-Drapeau.

St. Lawrence River

The St. Lawrence River is a grand river and estuary, which together with the Great Lakes forms a hydrographic system that penetrates 3,058 km into North America. The river proper, about 1,197 km long, issues from Lake Ontario, flows northeast past Montreal and Quebec City to the Gulf of St. Lawrence. The route of early explorers and the main axis of New France, the St. Lawrence River figured prominently in Canada's early history, and it remains the focus of settlement for much of the province of Quebec. It is still the most important commercial waterway in Canada, as well as a source of electric power and natural beauty. (See also St Lawrence Lowland.)
