About Us

OPSEU/SEFPO represents approximately 180,000 members across Ontario. They are full- and part-time workers, young and old. They trace their ancestry to all parts of the globe – as diverse a group as you could imagine. Our members work for the Ontario government, inside community colleges, for the LCBO, in the health care sector, and they are employed in a wide range of community agencies within the broader public sector.
