Shared currents: stewarding Canada’s water commons

This commentary explores how the Canada Water Agency (CWA) can play a transformative role in advancing national and regional water resource security and sustainability by adopting a Water Commons philosophy, one that views water as a shared system that connects communities, economies, and ecosystems across Canada. Framed around a cooperative federalism approach and shared stewardship, the CWA can help bridge jurisdictional divides and strengthen collective capacity to manage water equitably and sustainably. By enabling open data access, advancing predictive and integrative science, coordinating emergency responses, and promoting transparent performance reporting, the CWA can serve as a catalyst for collaboration among provinces, territories, Indigenous Nations, municipalities, and industry. Central to this approach is the recognition of Indigenous leadership, respect for local knowledge, and intergovernmental cooperation, all guided by a practical roadmap toward an inclusive and adaptive water governance model for Canada’s shared future.
