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.

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.
