The purpose of this paper is to offer an updated view of multistakeholder co-operatives (MSC) which are co-operatives with more than one members group. Theses co-ops can operate in new activities sectors and have the capacity to gather new socio-economic actors. The suggested method adopted by the author is to present, characterize and analyse the trends of MSC development in Québec base on data covering the period of 1997-2008, for instance, the annual set up of co-op and the sector of economic activity. This analysis indicates some key challenges for the management of these MSC’s especially the capacity to find compromise between diverse interests, for instance those of users and worker members. The Italian and French MSC cases have been occasionally used to delineate the Québec experience with MSC’s. Given the growing place taken by MSC’s in the co-op family, it would be pertinent over the next years to push forward new studies on their socio-economic impacts and the way they manage their place with single member co-ops in specific activity sector.
