  • Physician at Seaton House
Dr. Stephen Hwang is the Director of MAP Centre for Urban Health Solutions. Dr. Hwang is also a physician at Seaton House (Canada's largest men's shelter) and St. Michael's Hospital. Dr. Hwang's research has brought attention to the severe health risks faced by people who are homeless and vulnerably-housed in Canada.

At the close of Dr. Pat O'Campo's 11-year tenure, Dr. Stephen Hwang was named the centre's new Director. "The arc of my research is the same as the growth of the (research) centre," said Dr. Hwang. "It started as a tiny enterprise, just me doing little projects. A researcher's first impulse is to look at a problem and describe it: the (elevated) death rate among the homeless, their lack of access to mental health care. But research has to make a difference in people's lives." (Toronto Star) MAP director Dr. Stephen Hwang is one of the world's most renowned researchers in homelessness, housing and health. His groundbreaking research changed the conversation about homelessness and precarious housing in Canada - these are critical health crises that can be prevented. Dr. Hwang was the first to quantify the profound impact that homelessness can have on a person's life expectancy, proving that homeless men are eight times as likely to die as men in the general population. He co-led the At Home/Chez Soi study, the largest randomized controlled trial in history to evaluate solutions to address homelessness. Its success testing the "Housing First" approach persuaded the federal government to commit resources to scale up Housing First interventions across the country. Dr. Hwang is the director of MAP Centre for Urban Health Solutions, a scientist with the Li Ka Shing Knowledge Institute, and a professor in the University of Toronto's Department of Medicine, Dalla Lana School of Public Health and Institute of Health Policy, Management and Evaluation.
