The Mental Health Commission of Canada launched a $110 million initiative in 2008 to carry out five research demonstration projects focused on homelessness and mental health across five major cities. The projects aim to enhance understanding of effective interventions to achieve housing stability and improved wellbeing for homeless individuals with mental health issues, emphasizing community collaboration and sustainable results. Key strategies include the 'Housing First' model, integration of services, and significant stakeholder involvement to ensure long-term impacts.
