Tri Delta is boldly leading the way—and often setting the standard—on important issues such as: body image, mental health, inclusion, collegiate housing, leadership development and governance.


Whether serving as officers or participating in a chapter’s educational programming, our members are offered the support and opportunity to grow as leaders. Throughout the collegiate experience, Tri Delta’s members will attain core competencies and skill development in areas that empower them during their collegiate years and lifetime membership in Tri Delta.


Tri Delta understands that its members are college women first, and part of Tri Delta’s Purpose is to broaden the moral and intellectual lives of members. Whether by providing scholarship funds through Tri Delta’s Foundation to assist with educational costs, or by promoting academic success through innovative chapter programming, Tri Delta offers encouragement and support to collegiate members as they pursue academic achievement.


Tri Delta is committed to changing the way the world treats and defeats childhood cancer – locally through raising funds and support to children’s cancer charities and hospitals, and at the national level through our partnership with St. Jude Children’s Research Hospital. Tri Delta has raised more than $75 million for St. Jude since 1999, and as a result of our latest pledge, St. Jude to named its short-term housing facility on the St. Jude campus Tri Delta Place. Our collegiate chapters are on the front lines of raising funds and awareness for St. Jude on their campuses and in their communities.

Member Development

As part of the collegiate chapter experience, a member will participate in current, relevant and Tri Delta related educational programming that will inspire them to live, learn and lead – with Purpose. Over the course of the collegiate experience, a Tri Delta enjoys a host of opportunities for personal growth as a student, woman and leader. Throughout the collegiate experience, members will attain core competencies and skill development in each of these areas.

#WhyTriDelta - Words from the Canada Delta Chapter 

"I chose TriDelta because I come from a family who puts more emphasis on male success. Tri Delta is an organization who focus on me individually and their female body collectively which is what I need. This organization provides support, goals, and furthermore, acceptance. The ladies of this organization which I would love to call my sisters, are always there for me when I need them, I can talk to them if I am having a bad day, and they don't judge or want to run away from the problems or issues in my life I want to discuss about. So what is TriDelta to me? It is family."                                                                    - Nupinder Panesar  #WhyTriDelta 

"I initially joined Tri Delta for its philanthropy. As an aspiring pediatrician, I thought Tri Delta's contribution to St. Jude's and CHEO was amazing, and was something I wanted to be a part of. What was unexpected for me was the sisterhood that I found with all the girls, and the generosity and love that they all encompass. I feel so lucky that Tri Delta has chosen me, and I can't wait for all the exciting things to come!"

"From the outside looking in, you can't understand it. From the inside looking out, you can't explain it." #whytridelta because being a part of something so much bigger than yourself gives you freedom to shine as your own person and presents countless opportunities to grow as a woman. #whytridelta because every woman that has initiated into Canada Delta has helped shape this Chapter into being not only a strong sisterhood, but an academically-oriented, leadership driven organization filled with more amazing people than I could ever imagine.
