This study presents a global picture of the 371 government funded community-based mental health organizations (OCSM) and provides a description of the partnerships developed with community, institutional and inter-sector networks. The authors examine the diversity of the mental health community organizations based on the following characteristics: date of foundation, type and extent of territory, type and number of services offered, financial statement; participation in associations, participation in steering committees and models of partnership. The surface area of the territory, the size of the budget as well as involvement in steering committees appear to be enabling factors favouring the development of relations between organizations.
