Following a research funded by SSHRC, the article gives account of the impacts of the creation of four Health and Social Services Centres (CSSS) on relationships with community organizations and social economy enterprises in Loss of Autonomy Linked to Ageing Program. The study demonstrates that the advent of larger structures and the mobility of managerial staff, often from hospital, do not favour as familiar relationships as those experienced in Local Community Services Centers (CLSC) and still found in the smallest studied CSSS. Clinical Framework and Local Services Networks are shaped according to an integrated services logic unfit for community specificities. Well-founded or not, but acknowledged by HSSC managers, community organizations are clearly alarmed to be caught in a logic of harmonization and standardization for services provision, even where CSSS directions have so far managed to keep local features into account.
