University Faculty Student Societies History
Faculty Student Societies are the oldest form of student governance within Canada, with the University of Toronto, UCLIT being the first democratically elected student government society founded in 1854 on February 22. Faculty Student Societies are the beating heart of student life within each university faculty, acting as the umbrella organization. Key characteristics that make faculty-student societies different than student unions are that student societies solely focus on student life, mental well-being, professional development, and fellowship among a given faculty/college and do not tinker so much with the administrative academics side. Faculty Student Societies always have a membership fee/levy students pay through tuition. Student Societies give the most collegiate traditional experiences to their collective memberships by having a mascot costume, providing frosh weeks, graduation galas, formals, frost weeks, funding, and student-facing services. Other aspects some student societies have are houses under the umbrella that help students identify more closely with each other, similar to Harry Potter's four houses (Gryffindor, Slytherin, Hufflepuff, and Ravenclaw).

College Student Alliance (CSA)
The student associations of Cambrian, Centennial, Conestoga, Confederation, Durham, Fleming, Georgian, Northern, Sault, St. Clair, St. Lawrence colleges make up the College Student Alliance.
