Our History 100% Research for Over 80 Years

Since 1945, the Cancer Research Society (CRS) has been proud to accelerate scientific discoveries and research impact across Canada.

Staying True to Our Mission

A Long Tradition

It’s in the 1940s that Betty Caplan, faced with her mother’s cancer diagnosis, realized that this disease impacts everyone in some way. At a time when no Canadian organization was dedicated exclusively to funding cancer research, she decided to act. Alongside her friends, Etta Kastner, Hattie Rolbin, and Mildred Singer, she founded the CRS in 1945. From the very beginning, the CRS had a clear and unwavering mission: to exclusively fund research on all types of cancer to better prevent, detect, and treat the disease.

By 1946, the CRS had awarded its first four research grants of $600 each, amounting to an equivalent of more than $40,000 today. This initial step, driven by a steadfast determination to make a difference, gave rise to an organization that, over eight decades later, continues to push the boundaries of science. Today, the CRS is recognized as a leader in funding for cancer research.

The Story Behind Our Mission

Julia Gersovitz, niece of Betty Caplan, one of the four founders of the CRS, shares how a family loss led to the creation of the organization. She honors the vision and determination of the founders while emphasizing the enduring strength of the mission, over 80 years later.

Making a Lasting Impact

Over the years, the CRS has created different initiatives to ensure the lasting impact of its mission, such as signature events, annual campaigns, and much more.

In 2010, the Challenge Against Cancer program was created. This program offers its participants the chance to support cancer research while discovering the world and surpassing themselves through a variety of sporting activities. In 2025, this program has grown into an initiative that now includes the Challenge rose, a challenge dedicated to breast cancer research.
