The Health Plan at the University of Guelph has always been mandatory for students.

The Dental Plan was voted in later than the Health Plan, with different terms that included an opt out with proof of alternate coverage.

A joint referendum was held by the CSA and GSA in Winter 2021 asking students if they would like to add an opt-out option to the Health Plan with a fee increase. The joint referendum failed to meet quorum and therefore the current universal plan remains in place. The results are binding, and the health plan remains mandatory for all full-time graduate students.
