The Public Service Alliance of Canada represents nearly 240,000 workers in every province and territory in Canada and in locations around the world. Our members work for federal government departments and agencies, Crown Corporations, universities, casinos, community services agencies, Aboriginal communities, airports, and the security sector among others. PSAC is headquartered in Ottawa with 23 regional offices across Canada.

Formed in 1966, the Public Service Alliance of Canada is one of Canada's largest unions. 

PSAC strives to enhance its members' quality of life and has been at the front of a variety of significant and successful campaigns for workplace and human rights, including the struggle for equal pay, enhanced workplace health and safety and the rights of same sex spouses.

PSAC is working to achieve a compassionate and inclusive society free of sexism, racism, homophobia and all other forms of discrimination.

PSAC is committed to defending access to quality public services, and to social justice through emergency relief funding, anti poverty and development work both in Canada and around the world.
