Preserving Ontario's habitats

At Ontario Power Generation we believe that operating sustainably is a business responsibility which is why we have been supporting conservation organizations since 2000.

In managing our sites, we strive to maintain or enhance significant natural areas of concern and have partnered with recognized biodiversity stewards across the province to protect Ontario’s most vulnerable natural landscapes.

See how we are helping to build a more sustainable Ontario.

A history of partnership

Supporting Ontario’s rich biodiversity is something that is integral to our business. This isn’t just about being a good corporate citizen, it’s about doing what’s right to protect, restore and maintain our environment for future generations.

In 2000, we introduced our Regional Biodiversity Program which actively supports conservation organizations with a focus on reforestation projects and protecting wetlands, grasslands and lake and river projects.

Nurturing our station properties

Twelve of OPG’s generating sites have achieved “Wildlife at Work” certification and six of our sites have been further certified for their “Corporate Lands for Learning” programs by the Wildlife Habitat Council. These sites have both protected and enhanced wildlife habitats on their properties, demonstrating a commitment to environmental stewardship and the conservation of native biodiversity. For example, our Nanticoke site features 24 hectares of transformed, diverse woodland and grassland habitats, now home to species at risk, like the bobolink and meadowlark.
