[" To each his own " an intervention project at the CLSC Centre-Ville).]

This article deals with the C. L. S. C. Centre-Ville's experience with old people over the last five years. What characterizes this experience in particular is the isolation of the individual and the deterioration of the social milieu. Interventions were made on three different levels : individual, personal and individual care at home ; collective, organization of group activities; community, interventions aimed at improving the social conditions and health of the population and its milieu. The originality of this step lies in its global and multidisciplinary approach wherein all dimensions of health are interrelated (diagnosis established and treatments prescribed in light of the economic, social and psychological characteristics of the individual).
