The CUPE National Constitution as amended at the 2013 National Convention

The CUPE Constitution determines the union’s objectives and how the union operates. It forms the basis for the functioning of the more than 2,300 CUPE local unions across Canada.


The Canadian Union of Public Employees is Canada’s largest union. CUPE represents more than a half million workers in a wide range of occupations from coast to coast. CUPE is a democratic union in which the members make the decisions and set the policies. At all levels, it is the rank and file members who determine by majority vote what the Union does.

The CUPE Constitution came into existence at the Founding Convention in 1963 when the National Union of Public Employees (NUPE) and the National Union of Public Service Employees (NUPSE) merged to form the Canadian Union of Public Employees. Changes to the Constitution can only be made by the delegates at the Union’s Biennial Convention.

The CUPE Constitution accordingly belongs to the members of CUPE. It determines the Union’s objectives and how the Union operates. It forms the basis for the functioning of the more than 2,300 CUPE local unions across Canada.
