Supporting communities

We power communities,
communities power us

Ontario Power Generation (OPG) operates in every corner of the province. As part of our core values, we strive to be an engaged, productive member of every one of these communities. From public safety and environmental restoration, to youth outreach, local fundraisers, and Indigenous scholarships, OPG is lifting up our communities. Our power is a force for good.

Keeping communities safe is priority #1

With 66 hydro stations, 241 dams, and two nuclear stations, safety is OPG’s top priority. Learn how we are helping to educate the public and pursuing a safety-first culture across the province.

Territorial acknowledgment

Ontario is treaty territory. The province as we know it would not exist without the treaties, which set out the relationship between Indigenous peoples and the provincial and federal governments, and provide companies like OPG the ability to operate. By acknowledging the traditional Indigenous territories upon which OPG’s facilities are located, we are honouring the treaties and respecting the rights of Indigenous partners.
