Ontario Public Service Employees Union/Syndicat des employés de la fonction publique de l'Ontario

The Ontario Public Service Employees Union (OPSEU/SEFPO) is a prominent trade union in Ontario, Canada, established in 1975 as the successor to the Civil Service Association of Ontario, which was founded in 1911. Headquartered in Toronto, Ontario, Canada, its core mission is to strengthen the power of public service workers to advance social and economic justice for all workers.

OPSEU/SEFPO represents approximately 180,000 members across the province, encompassing a diverse range of public sector employees. The union provides essential services such as collective bargaining, advocacy for workers' rights, and promoting workplace health and safety. Its membership includes individuals working for the Ontario government, community colleges, the Liquor Control Board of Ontario (LCBO), and various community agencies within the broader public sector, including healthcare and education.

Currently, JP Hornick serves as the President, having been re-elected in April 2024 for a second two-year term, with Laurie Nancekivell as the First Vice-President/Treasurer. The union remains actively engaged in advocating for improved working conditions and robust public services for Ontarians. Recent efforts include addressing staffing and retention crises in public services, opposing legislation like Bill 124, and campaigning against privatization. OPSEU/SEFPO has also been involved in recent issues such as filing grievances over Manulife service delays for Ontario Public Service (OPS) members and responding to job cuts at Fanshawe College.
