This book contributes to the growing literature on the social economy from the particular perspectives of Atlantic Canadians who have been part of the Social Economy and Sustainability Research Network. It illustrates the importance of the sector to the region’s social, economic and public life while exploring its potential for positive change. Prefiguring an economy based on principles of human values and principles of solidarity, the social economy offers a space for people to exercise democracy in realms thought to be “economic” and thus exempt from such priorities. The social economy has the aim of development in a double sense—development of the individual and local or community development.
