In 1988, volunteers came together to create a non-profit organization called the Corporation Maison Lucien-L’Allier, the first mission to deliver affordable housing in downtown Montreal to people living with income below the poverty line. On April 21 of that year with the help of the Société d’habitation et de développement de Montréal decided to construct a building with 27 apartments, 21 studios and 6 apartments. The desire to offer these units to clients with mental health problems. The developer at the time of the project, Galleria Dorchester had created quite a stir in Montreal because it was to demolish houses of the Victorian era and a few wealthy clients to build new ones. Heritage conservation took birth.
When the property was purchased several deficiencies were found. Unfortunately for the Corporation, the contractor went bankrupt. Since that time, the Corporation must deal with these problems. Over the years, the Corporation had to execute major repairs, among others a crack in its foundation, in order to continue its operations.
In the early 1990s, the Corporation began receiving money from the Montreal Health Agency to provide services to its clients. The Corporation decided during this same period to only offer the apartments for people with mental health problems. Many directors from the hospital in connection with psychiatry.
In 2012, a new Board of Directors finds irregularities in the work and decides to make the necessary corrections and changes. The users will now be the majority on the Board of Directors. Since then major reforms have been undertaken (review of the mission, by-laws, creation of a tenants committee, developing partnerships with the CLSC, hospitals, community policing. The Corporation must become a community environment.
