The purpose of this paper is to examine the association of community treatment orders (CTO) with community engagement and housing arrangements for one population of psychiatric patients in Ontario, Canada. Socio demographic characteristics and health service utilization information were collected for each patient placed on a CTO during a 3 year period. Information was collected for each of the 84 patients when a CTO was first issued and then updated to reflect both the patient's ongoing involvement with the legislation and related clinical outcomes. A significant increase in the number of community services and a shift to supportive housing arrangements was found for patients following issuance of a CTO.
