CUPW’s national office is in Ottawa. The union has regional offices in Halifax, Quebec City, Montreal, Ottawa, Toronto, London, Winnipeg and Vancouver. There are CUPW locals with elected representatives in over 200 communities across the country.

Ultimate decision-making power in the union resides with the membership. At the local level, members make decisions about bylaws, local activities, delegates to national convention, etc. At the regional level, local delegates develop proposals for union policies, objectives, procedures and negotiations’ demands. Every three years, representatives from the locals meet at a national convention to decide on a plan of action for the coming years. They also elect national and regional representatives. CUPW’s national constitution and policies are the result of decisions from conventions.
