Ontario Power Generation (OPG) has been proudly operating in Eastern Ontario for over 100 years. Today we have one thermal facility and 10 hydroelectric generating stations on the St. Lawrence, Ottawa and Madawaska Rivers. These stations, their employees, and host communities play an important role in generating clean, reliable power for Ontario.

OPG is conducting fisheries research on the Madawaska and Ottawa rivers
Ontario Power Generation (OPG) is conducting fisheries research near its hydroelectric generating stations on both the Ottawa and Madawaska Rivers. The research includes fish abundance and habitat studies, supporting ongoing mitigation studies for American eel and lake sturgeon, as well as the Calabogie Generating Station redevelopment project. Kleinschmidt Associates, along with CIMA+, will conduct these studies from the shoreline and by boat, which may operate close to the shore during day and nighttime.
The research is conducted under permits from the Ontario Ministry of Natural Resources and Forestry, and the Québec Ministère de L'Environnement, de la Lutte contre les Changements Climatiques, de la Faune et des Parcs, and is required under a Fisheries Act Authorization from the Department of Fisheries and Oceans. Work on the Madawaska River will commence in late April and continue until early Fall, while on the Ottawa River, it will continue until mid-October.
Key projects and initiatives
Generating power with purpose
Our role in Ontario isn’t just measured by kilowatts (although we’re really good at producing them); it’s measured by our relationships, the impact we make, and the future we leave to the next generation. That’s why we strive to be good corporate citizens who care about the environmental, economic, and social wellbeing of all Ontario.
At OPG, we have a purpose that goes beyond generating clean, reliable, low-cost power – we’re helping generate a stronger, cleaner more prosperous Ontario.

Environmental initiatives
Madawaska River Water Management
OPG works with local waterpower companies and the Ministry of Natural Resources on a balanced approach to water management on the Madawaska River that considers the various interests of many users.
The result of this work is the Madawaska River Water Management Plan, which includes operational plans for each waterpower facility or dam, provisions for management of water levels and flows, stakeholder communication, and environmental programming.
