Hochelaga Archipelago

The Hochelaga Archipelago is the cluster of islands centred on the Island of Montreal in the Saint Lawrence River, within the province of Quebec, Canada. It includes both urban islands and numerous smaller, mostly riverine islets.

The archipelago’s largest island hosts the city of Montreal with its parks, historic districts and cultural institutions, while nearby islands such as Île Sainte-Hélène and Île Notre-Dame provide parkland and event spaces. Many smaller islands are protected natural areas or privately owned.

The archipelago’s name derives from Indigenous place names recorded by early European explorers in the 16th century; the islands have since supported Indigenous settlements and, later, urban development centred on Montreal.

The islands sit where the Saint Lawrence widens around Montreal and are linked to the mainland by multiple bridges and transport connections serving the Greater Montreal region.

• Number of islands: The archipelago comprises the islands at and around the confluence of the Saint Lawrence and Ottawa rivers and includes more than 200 islands of varying size.
• Name origin: The name Hochelaga recalls the 16th-century Indigenous settlement recorded by early European explorers and is used historically for the Montreal area.
