Why join us?

The IESO is committed to ensuring Ontario’s electricity system meets the province’s needs today and into the future. We are charged with purpose, delivering reliable, affordable, and sustainable electricity for homes, businesses, and communities across the province. We are energized to grow, embracing opportunities to shape the future of a dynamic and evolving energy sector while advancing our careers. We are powered by teamwork, supported by diverse and passionate colleagues who foster respect, celebrate successes, and thrive on shared achievements. At the IESO, it’s not just what we do—it’s who we are!

Who we are

Our central role includes managing the provincial power grid in real-time, overseeing and evolving Ontario’s electricity market, engaging with government, municipalities and Indigenous communities, and planning for Ontario’s future electricity needs. Our employees play a key role in driving grid innovation, protecting the system from threats, advancing the province’s energy conservation programs, and forecasting and procuring the electricity resources we’ll need in the decades to come.

At the centre of that transformation is our legal team.

Our lawyers work at the intersection of law, public policy, and energy transformation — advising on strategic initiatives, major procurements, regulatory matters, governance, and enterprise-wide projects. No two days are the same, and the work carries real public impact.

If you want challenging, varied work alongside exceptional colleagues, and the chance to build a broad and rewarding in-house practice, we'd like to hear from you.
