The Canadian Watershed Information Network (CanWIN) is a cutting-edge spatial research data infrastructure (SRDI) system based at the University of Manitoba and managed by the Centre for Earth Observation Science (CEOS). CEOS, a leader in multidisciplinary climate research, focuses particularly on the Arctic freshwater marine system—an area critically impacted by climate change. CanWIN supports large-scale, ecosystem-based studies by enabling the sharing, discovery, visualization, and analysis of diverse datasets, including sensitive Indigenous Knowledge. Originally developed by Environment and Climate Change Canada for Lake Winnipeg Basin research, CanWIN has evolved into a flexible, modular, open-source platform. In 2020, it underwent a major redevelopment to implement a distributed data ecosystem with CKAN as its central hub and a redesigned user interface aligned with UM’s identity, addressing the growing need for collaborative, cross-disciplinary environmental data management in support of urgent climate and water security challenges. They joined WDS as a Candidate member in June 2025.
