The Omicron-Pi Chapter at Carleton University was founded in 2007 and has since been the brotherhood of more than 300 members. We are one of the largest, most active, and dominant organizations on campus and also the top Canadian Chapter for our Fraternity. From the social scene to our academics, to our community service and campus leadership, our chapter is the strongest organization on campus.
