and Ontario College of Trades in the Broader Public Service.

In addition to members whose positions are based in Toronto but who work in field offices throughout the province, OPSEU Local 503 members can be found in eight different work locations in Toronto.




The Local 503 LEC is made up of the President, one Vice-President in each component (OPS and OCOT), Vice President of CommunicationsTreasurerSecretary and Stewards. These are elected positions with a term of 2 years. 

The Local Executive Committee is responsible for carrying out the financial and administrative business of the local under the terms set by the OPSEU Constitution. This includes: preparing and submitting quarterly audit reports,  running a minimum of 2 General Membership Meetings per year, representing the membership at the LERC, facilitating member participation in bargaining, and organizing local events. 


All members of the Local Executive Committee are also Stewards. In addition, our local has stewards in all of our office locations in Toronto, and several remote OCOT Enforcement Officer stewards. Stewards assist the LEC to communicate with and represent the members. 

The Steward’s Job in OPSEU is:

• Organizer and communicator
• Grievance handler
• A link to collective bargaining
• A link to the Local Executive
• A link to the central union
• A resource for members


The General Membership is made up of everyone who is represented by the local. A minimum of twice a year, the local executive organizes General Membership meetings. At these meetings the members have direct say in the local budget, bargaining demands, and initiatives of the local. You can also be involved by bringing your comments and ideas to your stewards, or by becoming a steward yourself! By getting involved you ensure your union represents your needs.

29.5.2 The Vice-President shall perform all the Presidential functions during any absence of the President and accept and exercise such other duties and powers as may be designated by the Local Executive Committee or the President.
