The Hochelaga Archipelago (), also known as the Montreal Islands, is a group of 234 islands at the confluence of the Saint Lawrence and Ottawa rivers in the southwestern part of the province of Quebec, Canada.
As of 1 July 2021, the Hochelaga Archipelago officially had 2,556,040 inhabitants in the following municipalities:
Estimates of the number of islands in the archipelago vary. The most widely accepted number seems to be 234, although the number has been put as high as 325.
The largest island in the group is the Island of Montreal, which contains most of the city of Montreal and the central section of its metropolitan area. The city has jurisdiction over 74 smaller islands in the archipelago, most notably Nuns' Island (also known as ÃÂle des Sà Âurs in French), ÃÂle Bizard, and the two islands that served as the site of Expo 67, namely Saint Helen's Island (in French ÃÂle Sainte-Hélène) and the artificial ÃÂle Notre-Dame.
The second-largest island in the archipelago is ÃÂle Jésus, which along with the ÃÂles Laval and several smaller islands makes up the city of Laval.
Other islands include the ÃÂles de Boucherville, featuring a Québec National Park, ÃÂle Perrot, Salaberry-de-Valleyfield and the neighbouring Grande-ÃÂle, as well as the smaller Dorval Island and Dowker Island.
The archipelago takes its name from Hochelaga, an Iroquoian settlement on the Island of Montreal that was later settled by the French and grew to become the modern city of Montreal.
