How do I become an OPIRG member? Full-time McMaster undergraduates are automatically members since they pay a refundable levy from their student fees. Students can opt out of the fee during the three weeks after drop and add. Anyone who is not full time at McMaster is able to join OPIRG as a Community Member for an annual fee on a sliding scale starting at $10.
