Canadian Breast Cancer Network / Réseau canadien du cancer du sein

By running for the Canadian Breast Cancer Network (CBCN), you are helping to change what it means to live with breast cancer in Canada. CBCN is the only national, patient-directed organization dedicated to ensuring that everyone affected by breast cancer has access to trusted information, meaningful education, and equitable, timely care—no matter where they live. Through strong advocacy, evidence-based resources, and a powerful national network of people with lived experience, CBCN amplifies patient voices to influence health policy and improve care across the country. Funds raised through the TCS Toronto Waterfront Marathon directly support programs that educate, empower, and advocate for better outcomes, so every step you take helps create a future where no one faces breast cancer without support, information, and a voice.
