Main image

The Island of Montreal is the Saint Lawrence River island on which the majority of the city of Montreal is located, forming the province’s principal urban and economic centre.

Key attractions include Mount Royal with parkland and viewpoints, the historic streets and museums of Old Montreal and the island’s downtown with major cultural institutions and business districts. The island also contains the Pierre Elliott Trudeau International Airport on its western side and an extensive network of parks, bridges and urban neighbourhoods.

The island has been inhabited and used as a transport and trading hub for centuries and developed into the main settlement that became the modern city of Montreal during the 17th and subsequent centuries.

Geographically the island sits at the confluence of the Saint Lawrence River and the Rivière des Prairies in southwestern Quebec; it forms the central component of the Montreal metropolitan area.

  • Mount Royal height: Mount Royal reaches approximately 233 metres above sea level and contains established parkland and viewpoints over the city.
  • Transport and culture: The island contains Montreal's Old Port, major cultural institutions and the city's international airport, making it the commercial and cultural core of the region.

Tips for Visiting Island of Montreal #

  • Rent a bike and take the Lachine Canal path westward for a quieter, more local view of the island's neighborhoods.
  • Visit the Jean-Talon Market in Little Italy (on the island's northern edge) for local produce and to catch the layered language life-French, English and immigrant languages-of the city.
  • If time is short, take the metro to Place-Saint-Henri or Lionel-Groulx and walk across to the island rather than starting from downtown.
