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.
See how we are a part of communities across Eastern Ontario and learn about our many local programs, initiatives, and events.

OPG is conducting American Eel & Lake Sturgeon research on the Ottawa River
Ontario Power Generation (OPG) is conducting research in the vicinity of its hydroelectric generating stations on the Ottawa River. Research activities will include fish abundance studies on the Ottawa and Bonnechere Rivers. This research, which is being carried out by Kleinschmidt Associates and CIMA+, is in support of OPG’s ongoing American eel and lake sturgeon mitigation studies for these species at risk.
Kleinschmidt and CIMA+ boats may be in close proximity to the shoreline as they complete day and nighttime fish abundance studies. This annual 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. It is completed in accordance with OPG Mitigation Plans under O. Reg. 242/08 (as amended by O. Reg. 176/13), under the Ontario Endangered Species Act. Work will continue until mid-October this year.
Please visit opg.com/biodiversity to learn more about OPG’s biodiversity programs. If you encounter either of these two species, please report it to us.
Key projects and initiatives
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.
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.

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.
