Policy and regulatory gaps exist at the regional-scale for managing municipal land use impacts on natural resources, such as air, water and ecological resources that cross multiple municipal boundaries and jurisdictions. In the Calgary Metropolitan Region in southern Alberta, three multi-stakeholder environmental bridging organizations (the Calgary Regional Partnership, the Bow River Basin Council, and Calgary Regional Airshed Zone) emerged, connecting municipal, public and private stakeholders who shared interests in land use, watershed and airshed management, respectively. These organizations co-created natural resource management plans (co-created plans) to address transboundary and interjurisdictional issues not addressed through provincial laws or municipal bylaws. Because the organizations have no legal mandate or authority, they operate alongside the provincial environmental policy and regulatory system. The Calgary Metropolitan Region provided a demonstration context for conducting transdisciplinary research, combining emerging theories of reflexive law, environmental governance, and bridging organizations. Reflexive legal theory is deliberately applied to support and legitimize the role of environmental bridging organizations in ‘bridging’ environmental policy and regulatory gaps between provincial and municipal authorities at a regional-scale.enreflexive legal theorytransdisciplinary researchenvironmental governancesystems theorybridging organizationssocial-ecological systemsjournal article10.11575/PRISM/34438
