Terry Fox Day is observed on the first Monday of August in Canada and commemorates Terry Fox's Marathon of Hope, a cross-country run he undertook to raise funds for cancer research. The day inspires Canadians and people around the world to participate in local runs, donate to cancer research, or share Fox's story to honor his legacy. Many organizations and businesses engage in fundraising efforts, with the Terry Fox Foundation offering official merchandise to support cancer research. Community-focused initiatives often include donation drives and local Terry Fox Runs, encouraging collective participation and fundraising. Notable supporters of the day include the Canadian Cancer Society and various businesses that contribute to cancer awareness initiatives. Terry Fox, who lost a leg to cancer, ran over 5,000 kilometers to promote awareness and funding for cancer research.
