The total compensation package for regular full‑time management roles includes pay‑for‑performance programs for annual and medium time periods. Maintaining a high‑performance culture and excellence is a core expectation of every member of our leadership team and is rewarded through the established compensation framework.

OPG is committed to employment equity. As such, we encourage applicants from equity‑seeking communities (Indigenous Peoples, racialized persons, persons with disabilities, and women).
