Omicron-Pi Chapter at Carleton University

est. 2007

Kappa Sigma is the largest college social fraternity in the world with more than 250,000 living members, including over 17,000 undergraduates and nearly 300 chapters and colonies located throughout the United States and Canada. Founded in 1869 at the University of Virginia, Kappa Sigma International Headquarters is based in Charlottesville, Virginia.

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.

Our Values


Want to get more from your college experience? Kappa Sigma makes it happen. Joining Kappa Sigma provides opportunities for fellowship, fun, and personal growth that you simply can’t get elsewhere. Over 280,000 men have joined and enjoyed the unmatched experiences, involvement, and lifelong brotherhood that Kappa Sigma offers. There is no secret…our goal is to build better men.


Take the lead. In Kappa Sigma, brothers learn to get involved in their communities and take the lead when something needs to be done. Countless brothers, including senators, governors and CEOs, have said Kappa Sigma gave them the leadership skills they needed to succeed.


You’re in college for an education. From its earliest beginnings in Renaissance Italy, Kappa Sigma has promoted scholarships among its members. Since its inception, over $4.5 million in scholarships have been awarded by the Kappa Sigma Endowment Fund to brothers who excel in academics, campus involvement, and leadership. At the chapter level, brothers help you learn about the campus, provide advice on professors and classes, and help you study for those important assignments.


Helping others is part of being a Kappa Sigma. Brothers spend thousands of hours working in their communities and raise thousands of dollars for worthy causes each year. From organizing park clean-ups to serving as Big Brothers to organizing charity rock concerts, Kappa Sigmas work hard for their causes. College is fun, but only service gives you the great feeling of knowing you’ve helped someone and made a difference.
