Decent place, but slow on the career ladder
Pros: IESO offers solid job security, which is a big plus in the public sector utility world. The Toronto office has some bright, experienced folks, so you learn a lot working on actual electricity sector challenges. Benefits package is pretty comprehensive.
Cons: Career growth is definitely a challenge here, especially as a Market Analyst. Internal mobility isn't super agile. It feels like there aren't many clear pathways to move up or switch departments without waiting ages.
Advice to Management: Focus on creating clearer career pathways and fostering more internal advancement. Encourage managers to support team members' growth beyond their current role.

Decent place, but culture needs a refresh
Pros: I've been an Energy Market Analyst here for a few years. People are generally smart, and IESO offers pretty solid job security in the energy sector. The Toronto office is in a good spot too.
Cons: The company culture can feel a bit rigid and slow, especially for new ideas. It's a very corporate environment, so things move really slowly, which can be tough. Sometimes it feels like there's a lack of innovation.
Advice to Management: Try to encourage more risk-taking and faster decision-making. Update processes to foster a more dynamic company culture for everyone working on the electricity grid.
