The Weekend to Conquer Cancer™ is a life-changing two days to raise funds for Princess Margaret Cancer Centre - one of the top five cancer research centres in the world.


Read about all the work we’ve done over the years to help shape the future of cancer care and research. Our community has raised over $176 million to date; read more about the real-life impact these funds have made for The Princess Margaret, here.


A Letter From Dr. Aaron Schimmer

Each year, The Weekend to Conquer Cancer™ (formerly the OneWalk) attracts thousands of participants and volunteers and I am always humbled by the tremendous support it receives from our community. I am again proud to walk alongside our staff and supporters. These fundraising efforts are critical for supporting the many research breakthroughs at Princess Margaret Cancer Centre, each having left an impact on the global stage.


About a year ago, I was appointed as the Research Director of the Princess Margaret Cancer Centre. One of my initial goals was to help accelerate cancer discoveries that impact our patients. To that end, we announced two priority moonshots—that is, areas within the cancer patient journey where we see opportunities to make significant headway. The first moonshot changes the way we diagnosis cancer, so cancers can be detected earlier to increase the chances of curing them. The second moonshot develops new treatments for advanced or metastatic cancers to increase rates of survival for these patients.


To achieve these goals, our scientists have made many exciting discoveries over the past year. For instance, a talented team of researchers developed a new test to detect and classify cancer at its earliest stages by tracking DNA released by tumours into the blood. Our extraordinary scientists have also unveiled new cancer targets by exploring how proteins interact with each other to drive the development of cancer. Finally, our team developed a new intervention to decrease psychological distress and improve coping in patients with advanced cancer.


It is without question that these successes were made possible by generous donations to The Princess Margaret Foundation and fundraising events like The Weekend to Conquer Cancer™. By supporting research, these impactful discoveries are helping to enable Future Care Now for patients here at the Princess Margaret Cancer Centre and around the world.


I hope you will join us this year and continue supporting the amazing work we are doing to improve cancer patient outcomes. There are many teams you can join or you can assemble your very own. I also extend a personal invitation for you to walk with me and join my team, Team Research. Hope to see you there!


With warm wishes,

About Cancer in Canada


Cancer is the second-leading cause of death worldwide. The International Agency for Research on Cancer estimates that one-in-five men and one-in-six women worldwide will develop cancer over the course of their lifetime, and that one-in-eight men and one-in eleven women will die from their disease.
