The OCA currently enjoys a membership of over 4,000.

Membership of the OCA provides you with a mailed copy of the tri-annual OC Magazine, which keeps you up to date with reports on recent events, archival articles, old boy announcements, and other information of interest.  Membership also grants you full access to the OCA website, which allows you to communicate and network with other old boys, remain informed of upcoming events, and access the OCA's member, mentoring and business directories and jobs board.

Members are invited to advise fellow old boys who are not members of the OCA of the many benefits of participation in the OCA, and to recommend that they become members.
