The Simon Fraser University Society (SFUSS) was established on October 5, 1965. "University" was later dropped and it is now known as the Simon Fraser Student Society (SFSS). The SFSS still maintains its original constitutional objectives: "to promote, direct, administer, coordinate all student activities of, by and for the students of Simon Fraser University, and to promote cooperation amongst the students of Simon Fraser University and cooperation between the members of the Society and students within the Province and elsewhere." Its mandate has come to include advocating for students rights and providing services to graduate and undergraduate members. These include advocacy services, such as Legal Aid and Women's Centre, and retail services, such as Quad Books, the Print Shop and the Pub.
In its first year, the Society organized social events, co-sponsored Vietnam teach-ins, started a co-op bookstore, and protested against the poor quality food offered on campus. In the 1970s, the Society organized against tuition fee increases, lobbied for improved on-campus housing, started a women's centre, and opened a student-run pub. The 1980s saw the development of plans for a student union building and a continuation in the struggle for affordable education. In the 1990s the Society has constructed the Maggie Benston Centre, expanded its services and continues to advocate on behalf of students for accessible, affordable education.
The Executive Council originally consisted of 14 elected officers: President, Vice President, Secretary, Treasurer, Ombudsman, Clubs Director, Public Relations Officer, Arts, Science and Education Presidents, Athletics Coordinator, Social Convenor, Cultural Director, and Housing coordinator. This remained until 1977 when changes to constitutional by laws established five at large positions: President, Treasurer, External and Internal Relations Officers, Secretary, and Public Relations Officer and the Ombuds Office. Currently, six elected Executive officers and 36 Student Union representatives elected by students from each academic department sit on the Forum, the student representative body responsible for all major Student Society decisions. The Departmental Student Unions and Standing Committees supply information and recommendations to the Forum. Student Society Standing Committees deal with every aspect of the Society's operations.
