Mission Unitaînés building in Longueuil officially opens as tenants move in

A 100-unit Mission Unitaînés building for independent seniors in Longueuil has officially opened and is already fully leased with tenants moving in. The project is part of a wider Mission Unitaînés effort that expanded to a planned 1,700 units across 17 cities.

The new Mission Unitaînés residence in Longueuil officially opened on Feb. 16, 2026, and tenants have begun moving into the 100-unit building. The residence at 900 allée Thérèse-Dallaire-Laplante is intended for independent seniors. The building is part of the first phase of Mission Unitaînés, which originally aimed to add 1,100 affordable units by building 11 residences in 11 cities. A second phase announced in August 2025 increased the planned total to 1,700 units across 17 cities. Key details: - The building contains 100 units and is reported as fully leased with tenants already moving in. - Partners named in the project include the governments of Quebec and Canada, Mission Unitaînés, the City of Longueuil and RÉSIDES-H. - Government investments tied to the partnership total $370.1 million and stem from the Canada–Quebec Agreement under the Housing Accelerator Fund and matching Quebec investments announced in 2023 and 2024. - The City of Longueuil donated the land, provided tax measures and covered utility connection costs. A philanthropic donation of $500,000 from Luc Maurice helped complete the financing package. - The official opening was attended by provincial and federal representatives, local officials, Mission Unitaînés and RÉSIDES-H leaders, and Pierre Karl Péladeau, who announced a financial contribution and noted that Vidéotron has increased its total contribution to one million dollars. Summary: The Longueuil opening adds 100 affordable units for independent seniors and is presented as the result of municipal, provincial, federal and non-profit collaboration. The work is described as part of the broader Mission Unitaînés program, which was expanded to a planned 1,700 units across 17 cities; further steps are undetermined at this time.
