The present study replicated the L.A. approach using a made in Canada definition to estimate the size of the hidden homeless population in Metro Vancouver. The L.A. study definition was deemed too restrictive for Canadian purposes; it was felt that the focus on outdoor structures not meant for human habitation would not reflect the reality of Canadian winters and would not capture the phenomenon of temporary shared accommodation. The objectives of the research were to: • Develop a definition of the hidden homeless that can be used nationally and implemented through the pilot study; • Refine the L.A. methodology for estimating the number of hidden homeless so that it could be used in communities across Canada; • Determine the feasibility of identifying the characteristics of the hidden homeless population; • Explore approaches to estimating the lifetime incidence of hidden homelessness; • Estimate the current size of the hidden homeless population in Metro Vancouver; • Learn about the characteristics of the hidden homeless and pathways into and out of hidden homelessness for some hidden homeless in Metro Vancouver; and • Assess the potential for replicability of this research elsewhere in Canada.
