One of the most anticipated parties of the social calendar!


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 17 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.

2022 Update

Hey Boobyballers! We know you’re eagerly awaiting the return of Boobyball — we are too. Rethink Breast Cancer is committed to evolving Boobyball to ensure it can continue to support young people affected by breast cancer in the most sustainable and effective way. What that means in terms of partnerships, logistics and execution is still being determined, but at the core of our vision, is our steadfast dedication to the evolution of Boobyball. 

Since 2002, Boobyball is one of the industry’s most coveted and high-profile fundraising events and we are eager to find the best path forward to continue its remarkable legacy and transformational impact. This year marks the 20th anniversary since a crew of Sarah O’Regan’s closest friends came together to plan a party to support Sarah while also raising funds for the cause. This idea created Boobyball and since then, the annual soiree has raised over $5.2 million for Rethink Breast Cancer. 

We had hoped to have more concrete news to share at this time, but like many things during this pandemic, we’re still working out the details. We look forward to providing an update early next year and appreciate your commitment and support to Rethink and Boobyball. Thank you for hanging in there with us!

The Origin Story

Running is a passion for Sarah O’Regan and when she headed to Vancouver after graduating from Western University, Sarah caught the triathlon bug. On one of her beautiful West Coast runs she began to notice frequent pain in her chest and was finding it difficult to breathe. Thinking the breathing problem was asthma, Sarah went to her doctor to get to the bottom of it. After a battery of tests, she was diagnosed with stage 4 breast cancer. She was only 23 years old.

The diagnosis was a total shock. At her young age, she didn’t know much about it, didn’t know anyone else in their 20’s diagnosed with it, and assumed it was something that only affected older women. Because her cancer was advanced, Sarah had little time to even let the news sink in. She was rushed into surgery and chemotherapy within days of her diagnosis.

Sarah at the first Boobyball in 2001

When Amanda Blakely, Sarah’s best friend since kindergarten, mentioned she wanted to throw an event to raise Sarah’s spirits, she was expecting a small gathering. But to her surprise, she walked into a full-on fundraiser packed with 600 friends and family all there to show their support – and Boobyball was born!

Today, Sarah’s cancer is NED and she continues to attend Boobyball year after year. She even brings her kids to Boobyball Mini! It’s an annual benchmark, reminding her of how far she’s come since that first event. Sarah’s life was forever changed by her cancer experience. At such a young age, she developed the insight and wisdom of a woman far beyond her years as well as an appreciation for all things in her life, big and small. She cherishes every day and is determined to live life to the fullest.
