The At Home/Chez Soi research demonstration project was a community mental health intervention funded by the Mental Health Commission of Canada to evaluate a Housing First (HF) approach to housing individuals with histories of homelessness and mental health problems and illnesses with no prerequisites of sobriety or participation in treatment. This report focuses on participants' experiences and changes in specific domains (housing stability, quality of life, community integration, and recovery from mental illness and addictions), ascertained through consumer narrative interviews at baseline and 18-month follow up.
