Boobyball was launched in 2002 by a group of dedicated young women in support of their friend Sarah O’Regan who, at just 23 years old, was diagnosed with aggressive, advanced breast cancer. Boobyball is now one of the most coveted and high profile fundraising events for young philanthropists with 4 events across Canada.

Over the past 15 years Boobyball has raised over $4.3 million dollars for Rethink Breast Cancer!

Boobyball Mini

Inspired by the original Boobyballers, many of whom are now parents, Rethink introduced Boobyball Mini in 2016 as a way to continue the fundraising fun for the next gen.

The afternoon affair is a one-of-a-kind event with great entertainment, music and décor set to a kiddie theme. Parents mingle over cocktails while kids explore our family-friendly activities.

All proceeds from this event will go directly to Rethink Breast Cancer’s mission to empower young people worldwide who are concerned about and affected by breast cancer including some resources for families dealing with cancer.
