Stephen Lewis, a notable Canadian leftist political leader and AIDS activist, passed away at the age of 88 in a hospice in Toronto due to cancer. Lewis was instrumental in leading Ontario’s New Democratic Party during the 1970s, a period marked by his father, David Lewis's leadership of the federal New Democrats. After stepping away from party politics in 1978, he became a prominent commentator and served as Canada’s ambassador to the United Nations in the 1980s. His later work focused on African affairs, particularly addressing the AIDS epidemic, where he became a vital voice against denialism. In 2003, he founded the Stephen Lewis Foundation, which aimed to raise awareness and support for those affected by AIDS in Africa. His legacy as an orator and activist continues to inspire many, including those who sought his guidance during challenging political times. Just days before his passing, his son, Avi Lewis, was elected to lead the New Democrats as they work to recover from a recent electoral defeat.
