Meaningful lessons about decolonising water infrastructure (social, economic and political) can be learned if we scrutinise existing governance principles such as the ones provided by the Organisation for Economic Cooperation and Development in 2021’s Principles on Water Governance. Instead of usingonlyWestern frameworks to think about policy within Indigenous spheres of water, sanitation and hygiene, the Government of Canada can look to Indigenous ways of knowing to complement their understanding of how to govern areas of water, sanitation and hygiene efficiently. In this paper, the termIndigenousencompasses First Nations, Inuit and Métis populations. This paper is presented asastep out of many towards decolonising water governance in Canada, and is intended to show that it is necessary to make space for other voices in water governance. By highlighting the dangers in the case studies, three lessons are apparent: (1) there needs to be an addition of Indigenous Two-Eyed Seeing in water governance; (2) Canada must strengthen its nation-to-nation praxis with Indigenous communities; and (3) there needs to be a creation of space in water, sanitation and hygiene that fosters Indigenous voices. This is necessary such that there can be equal participation in policy conversations to mitigate existing problems and explore new possibilities.
