AMAPCEO is a member-driven, politically non-partisan union of more than 14,000 professional employees, dedicated to providing outstanding representation and other services to our members. We protect members’ rights, defend Ontario’s public services, and advocate for better working conditions for everyone.

Established in 1992, AMAPCEO has built a strong record of negotiating innovative collective agreements, developing a collegial, problem-solving approach to dispute resolution, and advocating for a professional public service. 

Members include: policy analysts, financial analysts, auditors, economists, mediators, arbitrators, educators, information technology professionals, scientists, chaplains, veterinarians, program supervisors, child and youth advocates, clinical coordinators, psychiatric patient advocates, media relations and communications officers, epidemiologists, arts granting officers and many others.

The union also represents senior economic officers in the Ontario Ministry of Economic Development, Job Creation and Trade, who are based in Canadian high commissions, embassies and consulates abroad.

AMAPCEO was established in 1992 as a grassroots organization to represent a group of employees in the Ontario Public Service (OPS) who, at that time, were excluded from collective bargaining. In 1993, AMAPCEO negotiated a Social Contract sectoral framework agreement with the provincial government on behalf of all excluded employees. When amendments to the Crown Employees Collective Bargaining Act were adopted, extending collective bargaining rights to some previously-excluded employees, the union signed up a sufficient number of members to achieve voluntary recognition as a bargaining agent in 1995. An interim agreement was adopted in 1996 and a first full Collective Agreement was ratified in 1998.

AMAPCEO has grown to be the second-largest union in the OPS—tripling its original membership at certification—and expanding outside the OPS to represent seven bargaining units in the Broader Public Sector. Six units consist of employees whose work was divested from the OPS under successor rights and one—the Ontario Arts Council—was independently organized after approaching AMAPCEO for assistance.  (An eighth BPS unit, the Ontario Racing Commission, was also independently organized and represented by AMAPCEO until the ORC's 2016 merger with the Alcohol and Gaming Commission of Ontario.)
