The Concordia Student Union (usually referred to as the CSU) is the organization representing all undergraduate students at Concordia University in Montreal, Quebec, Canada.
[1] It is governed by a council elected by students.
The CSU was originally named the Concordia University Students' Association (CUSA).
It was incorporated in 1982 as the Concordia University Students' Association Inc.
[2] In 2001, CSU undertook an accreditation drive, to legally represent all undergraduate students at Concordia, and was successful in its endeavour, though heavily opposed by the accredited faculty undergraduate student associations for Engineering and Commerce.
