Our study aims to understand the outcomes and experiences associated with participation in the Transitions to Home (T2H) program in Hamilton, Ontario. Established in 2010, T2H helps men experiencing long-term shelter use and homelessness acquire and maintain safe, affordable and long-term housing in the community. T2H follows the Housing First model, an evidence-based approach to addressing homelessness. Researchers have suggested there is a need to understand the impacts of Housing First in different communities and populations. Our study was designed to respond to the need for a locally based evaluation of Housing First in Hamilton.
