Responding to COVID-19 with integrative health and sheltering models for persons experiencing homelessness in Southern Ontario, Canada: protocol for a qualitative study exploring implementation and sustainability.

introductionCOVID-19 has disproportionately impacted persons experiencing homelessness in Canada, who are at an increased risk of infection and severe outcomes. In response to the pandemic, several regions have adopted programmes that aim to address the intersecting nature of health and social challenges faced by persons facing homelessness. These programmes adopted during the pandemic may contribute to broader health and social impacts beyond limiting COVID-19 transmission, but the processes involved in developing and implementing these types of programmes and their sustainability after the pandemic are unknown. Our overall goal is to understand the processes of developing and implementing integrative health and sheltering initiatives in Ontario during COVID-19, as well as their sustainability post-pandemic. METHODS AND ANALYSIS: This study will use a multiple case study design-two cases over 1 year-enabling us to investigate how integrative health and sheltering approaches have been implemented in two mid-sized cities in Ontario, Canada. Each case will offer a unique narrative; through cross-case analysis, the cases will highlight programme operations, successes and challenges. Data will be collected using semi-structured interviews with programme staff and managers, and document analysis. Project partners will be brought together to further explore and interpret findings, along with co-creating a sustainability action plan and policy documents. ETHICS AND DISSEMINATION: Ethics clearance was obtained through the Western University Research Ethics Board and the University of Waterloo Office of Research Ethics. Findings will be disseminated through publications, conference presentations and lay summary reports.
