Excerpt from the Introduction: . . .This report presents an overview of research, data, interventions and policy directions related to mental health and homelessness. It is organized into two sections. The first section presents compiled estimates of the prevalence of both homelessness and self-reported mental health issues among the homeless across Canada. The second section looks at the effectiveness of two types of related policies and programs-housing and community mental health programs-and their role in promoting mental health and helping people find a way out of homelessness. The report concludes with an overview of what we know and what we do not know about the links between mental health and homelessness. . . .
