The goal of this project is to support policy work and service planning by providing reliable information about the characteristics and service needs of tenants in the Domiciliary Hostel Program in Ontario. The specific objectives of this research project were: 1) To describe the characteristics of Domiciliary Hostel Program tenants; 2) To describe Domiciliary Hostel Program tenants’ use of community supports and services, use of health care, and participation in community life; and 3) To describe the housing pathways of Domiciliary Hostel Program tenants. Data were collected through face-to-face interviews with a representative sample of Domiciliary Hostel Program tenants in 8 CMSMs. Additional information on study participants was obtained through linkages with provincial databases.
