OSSTF/FEESO holds an Annual Meeting of the Provincial Assembly (AMPA) every March in Toronto, which is attended by representatives from all of its Bargaining Units. The Provincial Assembly is the highest legislative body of OSSTF/FEESO, and is responsible for establishing and amending Federation policies, procedures, bylaws, constitutions, budgets, and the Strategic Action Plan. It passes motions, adopts the OSSTF/FEESO budget, and elects the Provincial Executive and OTF Board of Governors during election years.
