Rethink Events

We pride ourselves on throwing exciting, entertaining, unique events – all in the name of raising money and awareness for the work we do at Rethink to support young women with breast cancer.

and third-party events.



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 in Toronto, Calgary and Winnipeg.
Over the past 12 years Boobyball has raised over 3 million dollars for Rethink Breast Cancer. In 2014, Big Top Booby took the greatest party on earth over the top in an explosively spectacular, circus-inspired night. Together the events raised over $423,000 and we welcomed Winnipeg as our newest addition to the Boobyball roster.
Check back soon for details on Boobyball 2015…coming to FOUR cities across Canada!

Rethink At The Races

On July 6, 2014, Rethink at the Races brought together Toronto’s best and brightest style-questrians for a vintage garden party complete with swanky delights, music, festivities and the royal treatment.

The event was a not-to-be-missed affair, raising over $61,000!
This summer, Rethink Breast Cancer invites you once again to wine, dine, win, place and show with the hippest of Toronto’s horsy set, at the second annual Rethink at the Races – our glamourous party, set at Woodbine Race Track.
Be among 300 of our most eminent supporters and style-questrians to enjoy a full day of swanky delights, music, festivities and the royal treatment under our exclusive Marquee Tent, while taking in VIP views of the world’s finest horse races.
