YUGSA is a students' union dedicated to representing graduate students at York University and advocating for their interests. As Local 84 of the Canadian Federation of Students, they are committed to lobbying, research, and community mobilization to oppose the commercialization of Canadian universities. They also work towards accessible, public, fully funded, and high-quality post-secondary education.

YUGSA's structure includes the Membership, which encompasses all graduate students at York University. The YUGSA Council serves as the governing body, consisting of student representatives from each department, members of the YUGSA Executive, Graduate Student Senators, and a Graduate Student Governor. The Council meets monthly to manage the association's affairs.

Departmental Graduate Student Associations (DGSAs) are formed within various graduate programs and offer services and support to their members. The YUGSA Executive, composed of elected members, handles the day-to-day operations of the association. Additionally, they have staff members to provide assistance and support.

YUGSA encourages student involvement through committees such as the Equity-Campaigns Committee and the York Cross-Campus Alliance. They also welcome suggestions for starting new committees or working groups. Stay updated with YUGSA on social media to connect and engage with their community
