We also offer training program opportunities across OPG in both our nuclear stations for nuclear operators in training, and hydroelectric operations for hydroelectric operating technician trainees.

Beyond engineers and trades, a wide variety of professionals support our business in many ways across the province. These important roles include positions in project management, supply chain and procurement, human resources, health and safety, finance, and law.

Finally, OPG actively provides opportunities for the next generation by recruiting students from universities and colleges for paid-work terms directly related to their field of study.
