The Ontario Secondary School Teachers’ Federation (OSSTF/FEESO) is a union representing roughly sixty thousand secondary school teachers and education workers across Ontario, focusing on public English-language secondary education and related staff within major school board organizations as well as certain universities and independent schools. Its core role is to establish working conditions for members while advocating for a robust public education system that safeguards academic freedom, prevents privatization, and ensures inclusive, bias-free learning environments for all students. Based in North York, Ontario, the organization operates within the primary and secondary education sector and positions itself as an independent, socially active union aligned with public education and student rights. In addition to its advocacy work, OSSTF/FEESO engages with broader education issues, including funding and service quality for public education, and has pursued recognition for its headquarters project and related facilities in recent years. Acknowledging its long-term presence in the sector, the federation supports members and educational workers through collective representation and policy advancement within Ontario’s education landscape.
