Community Engagement

The OWA has long recognized the importance of positive and productive relationships with Indigenous communities, municipalities, and associations. Ontario is fortunate to have significant untapped waterpower potential. In the north, realizing this potential will undoubtedly involve the participation of municipalities and Indigenous communities. To date, more than two dozen municipalities and three municipal organizations in Ontario have pledged their support for waterpower by becoming “Waterpower Champions”. The OWA has developed resources designed to empower and foster community engagement in Made-in-Ontario waterpower projects.
