The What Would it Take study asked young people with lived experience of homelessness: what would it take to prevent youth homelessness in Canada? Between July 2017 and January 2018, A Way Home Canada and the Canadian Observatory on Homelessness consulted with youth across Canada to ask: 1) What would have prevented your homelessness? 2) What programs, policies, services, and supports are needed to prevent youth homelessness? 3) What do you want to tell the Canadian government about preventing youth homelessness? 4) How do you want to be involved in making change on this issue? The purpose of this report is to amplify the voices, insights, and wisdom of these young people in order to drive policy and practice change.
