Delta Psi Delta  is one of only three Canadian National sororities. Delta Psi Delta was founded on September 15th, 1991 to help the women of Carleton University maintain friendships while contributing in a positive way to the Ottawa-Carleton community. Our Motto, "Our Unity is our Strength," describes the way in which we are able to work together in supporting our community through our work with the Ottawa Food Bank and the local Battered Womens Shelters. Delta Psi Delta is a Canadian National Sorority that helps its members achieve a balance between school work, philanthropy, and the social aspects of University life. Over the last two decades it has grown to include chapters around Ontario, and is now aiming to be recognized as one of Canada's National Sororities.

Delta Psi Delta is a mixture of races, religious beliefs and diverse backgrounds and are all associated in some way with either a Canadian University or College. We accept all women who posses the same beliefs to better life for woman and for all and who strongly believe in our motto "Our Unity Is Our Strength". We rush new members at the start of each semester by hosting information nights in which girls are encouraged to find out more about Sororities as a whole, thus being completely free to inquire and to rush all sororities.
