Since 2001 the Ontario Waterpower Association (OWA) has been representing the common and collective interests of the waterpower industry. To date our membership has grown to over 150 organizations, including generators, engineering firms, environmental consultants, legal, project financing and insurance firms, Aboriginal communities and other organizations, all sharing the common interest of advancing waterpower in Ontario. The OWA hosts the Power of Water Canada Technical Conference & Trade Show annually, which has now grown to be the largest gathering of the hydroelectric sector in Canada.
