OPIRG-Peterborough’s membership is largely comprised of full-time undergraduate students at Trent University who pay the annual levy fee to support OPIRG. Part-time and graduate students, as well as community members, can also join OPIRG by paying the equivalent membership fee.

OPIRG is a membership-driven organization. Each spring during the OPIRG Annual General Meeting the membership elects the organization’s board of directors, as well as reviews and approves the financial records. Members can also attend board meetings throughout the year. All working group proposals must be endorsed by member signatures before being considered for approval as well.

The OPIRG levy is refundable for full-time undergraduate students at Trent University.
