The Triangle area, located in Côté-des-Neiges-Notre-Dame-de-Grâce, is the site of urban transformation efforts including upgrades to infrastructure, the redesign of public spaces and the development of social housing.


The Triangle district is located in Côte-des-Neiges–Notre-Dame-de-Grâce, east of Montréal’s former horse racetrack. It forms a triangle of approximately 40 hectares, bordered by Avenue Mountain Sights to the west, Rue de la Savane to the north and east, and the Canadian Pacific Railway tracks to the south. The Triangle project is at the centre of a major planning effort for the Namur–De la Savane district (which includes the former hippodrome).

Historically the site of automobile-related businesses, and displaying a rather “destructured” character, the Triangle site offers many possibilities for urban revitalization, due especially to its proximity to the Namur metro station. Several studies have been carried out for this purpose, including the development of an overall vision, inspired by the Transit-Oriented Development approach (TOD). In 2011, Côte-des-Neiges–Notre-Dame-de-Grâce held an urban design competition which led to adoption of a plan to redesign the sector. The plan was implemented from 2013 to 2018.

The project included for main components: private real estate development including social and community housing, upgrades to municipal infrastructure, redesign of public space to take into account the district’s new land uses, and the addition of green space and public facilities.
