The TST Graduate Students’ Association (TGSA) exists for the benefit of all graduate students at the Toronto School of Theology. Whether full time or part time, all graduate students enrolled at any TST college are members of the TGSA, pay fees to the TGSA, and can nominate and elect their fellow students to the TGSA Board.

As described in the TGSA Constitution, the TGSA provides a forum for the expression of student concerns, acts as a liaison with the TST administration, and provides student representatives for TST Councils and Committees. TGSA also encourages cooperation and community between students and faculty, promotes the social and political participation of students, and organizes opportunities for student academic and professional development.
