Governance and regulation

Accent: hpkzracljs7y

Strong governance for strong performance

To be an effective and efficient energy provider, Ontario Power Generation (OPG) has developed corporate governance and leadership policies and programs.

The Province of Ontario is OPG’s sole shareholder. This means that, each quarter, the activities of OPG and its subsidiaries generate hundreds of millions of dollars for the province to spend on roads, bridges, schools, hospitals, or other provincial priorities. To generate this return while providing clean, reliable, and low-cost power to the people of Ontario, OPG relies on robust governance structures.

Explore the principles, directives, and leadership that help guide our decisions, for the benefit of Ontario.
