Montreal historical timeline

Montreal's history is visible in the meeting of river routes, Indigenous presence, French colonial settlement, industrial waterways and twentieth-century megaprojects. The story is not a straight progression from old town to modern city. It includes displacement and alliance, religious institutions, migration, labour, changing language politics and repeated efforts to remake the island's infrastructure.

Chronology

1. 1535 Jacques Cartier reached the large St. Lawrence Iroquoian village of Hochelaga near Mount Royal. The encounter records an urban Indigenous presence before French settlement. The mountain and the archaeology beneath the old city preserve parts of that deeper history.
2. 1642 Jeanne Mance, Paul de Chomedey de Maisonneuve and their companions founded Ville-Marie as a French Catholic mission. The settlement stood near the meeting of the St. Lawrence and the former Little Saint-Pierre River. Archaeological remains of Fort Ville-Marie are now incorporated into Pointe-à-Callière.
3. 1701 Governor Louis-Hector de Callière and delegates from many Indigenous nations concluded the Great Peace of Montreal. The agreement ended a long cycle of conflict and reorganised diplomacy and trade around New France. Pointe-à-Callière interprets the treaty and the people involved.
4. 1825 The Lachine Canal was completed to bypass the rapids west of the city. Later enlargements helped turn its banks into Canada's most important early industrial corridor. The canal closed to commercial navigation in 1970 and reopened to recreational boating in 2002.
5. Mid-19th century Port, rail and canal connections accelerated manufacturing and immigration. Irish, Scottish, English, French Canadian and other communities changed the city's institutions and neighbourhoods. Warehouses, workers' housing and the canal landscape keep that transformation legible.
6. Late 19th to early 20th century Dense duplexes, triplexes and multiplexes spread through expanding districts. Their exterior stairs and balconies gave separate homes direct access while using narrow urban lots efficiently. The Plateau and adjoining neighbourhoods still carry this characteristic streetscape.
7. 1962 Interior passages connected Place Ville Marie with Central Station and the Queen Elizabeth hotel. The network expanded alongside the metro and preparations for Expo 67. Today's RÉSO links transport, offices, shops, cultural venues and institutions across downtown.
8. 1966 Montreal's first 20 metro stations opened. The initial 26-station network was completed the following spring, giving the city rapid transit in time for Expo 67. Its rubber-tyred trains and station architecture became part of Montreal's design identity.
9. 1967 Expo 67 occupied an enlarged Île Sainte-Hélène and the new Île Notre-Dame. More than 50 million visits brought global architecture, performance and technology to the river. The Biosphere, Habitat 67 and Parc Jean-Drapeau remain its clearest physical legacy.
10. 1976 Montreal became the first Canadian city to host the Olympic Games. The stadium, pool and former velodrome remain active; the velodrome was later converted into the Biodome. The scale and cost of the Olympic works still shape debate about public megaprojects.

What survives

Montreal's old fabric survives in fragments and systems rather than as a sealed historic centre. Stone commercial buildings, religious institutions and archaeological sites stand beside port infrastructure and later offices. Along the Lachine Canal, industrial buildings have found new uses while the waterway remains a national historic site.

Neighbourhood continuity matters just as much. Markets, congregations, businesses and housing types show how successive communities made the city their own. Preservation therefore involves more than façades: it also means keeping ordinary districts inhabitable and recognising Indigenous and migrant histories that earlier monuments often left out.
