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.

Over the past 22 years, Boobyball has raised over $5.2 million dollars for Rethink Breast Cancer. Boobyball is now one of the most coveted and high-profile fundraising events for young philanthropists in Toronto, Calgary, Vancouver and Ottawa.
