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.

The Power for Change Project

OPG believes our power can help change the world, and not just by electrifying economies. This project was designed to give back to Ontario and to the communities where we operate, to help build a cleaner, more sustainable future for generations to come.
