Access to healthy food for all in dignity is inseparable from the issues of equity and sustainable food security. To work effectively on the issues of sustainable food, in a systemic approach based on cooperation and mutualization in all communities of the Saguenay–Lac-Saint-Jean, the Comité régional de réflexion et d’action en sécurité alimentaire (CRRASA) and its subcommittee Cuisinons et cultivons du Lac au Fjord (CCLF) participate in the development of a project of collaborative spaces for food processing. This project will allow, among other things, a universal and equitable offer of local and healthy packaged products that can be processed for various clienteles, in a structuring approach to consolidate the food system and make it more sustainable. The project is part of a strategic plan to increase regional food autonomy, supported by the Borée approach. This article aims to present this illustration of a systemic approach and the contribution of intersectoral concerted action to respond to the issues of food insecurity.
