The Concordia Student Union (CSU) is an association that represents more than 35,000 undergraduate students from 4 different faculties: Arts and Science, Engineering and Computer Science, Fine Arts, and John Molson School of Business. Their mission is to serve undergraduate students, defend their rights, and act as the highest representative student body within Concordia University.

The 2019-20 Student Union executives voted to do a full rebranding of the association. Their vision was to bring the four faculties together by creating a brand identity that portrays togetherness, connection, and community. The rebranding was made in collaboration with Mairi Watson.
