This Guide serves as a companion document to the report We’ll Leave The Lights On For You: Housing Options For people Experiencing Persistent Homelessness Who Use Substances (Alcohol and/or Drugs) in order to support local planning and program development. It includes detailed information with respect to features of programs designed to serve people experiencing persistent homelessness community support programs. This Guide was informed through site visits conducted in 2009 at various supportive housing programs in Hamilton, Toronto and Ottawa as well as a program/document review.
