This article examines the forms of governance that characterize the community sector, referring to two case studies of local partnerships initiated by the group "Quebec en forme" (QEF) in the Outaouais and Mauricie regions. The increasing participation of community organizations in the delivery of public services highlights the importance of cross-jurisdictional cooperation and partnerships within the framework of a more horizontal governance. The article presents some of the challenges surrounding governance construction in the community sector. The weight of traditional power structures, as well as the innovations proposed in the literature on governance and the implementation of a horizontal approach (securing broader partnerships, developing new shared objectives, etc.), are not easily adopted in community practice.
