Continuously, the Quebec system of social housing is affected by the transformations of care systems for people with disabilities. Generally, the “residence” is THE privileged place of intervention for the improvement of health and well-being. The origins of these changes correspond to the will of finding alternatives to the cumbersome and costly processes in institutions, but mainly to create real opportunities for people living there. The interfaces between the health sector and social housing are thereby increased (targets and missions). We are witnessing a shift of boundaries between these two worlds. Nor lodging, nor housing, these new alternative living spaces are, in some ways, hybrids. Nonetheless, all these hybrids, despite the problems they can generate, are carriers of innovative approaches that could be recognized in the development of programs and policies for alternative living. This article reports on research funded by CIHR. From the eight cases studied in the sector of seniors with disabilities, a characterization of the manifestations of the phenomenon of hybridization will be made. The article will focus on considerations for evaluating the penetration of the universe of accommodation and lodging in the housing sector for seniors with disabilities and the impact this has on inclusiveness and citizenship.
