Former MP Kirsty Duncan Passes Away at 59 After Cancer Battle

Kirsty Duncan, a former cabinet minister and prominent figure in Canadian politics, has died at the age of 59 after a courageous battle with cancer. Duncan had been open about her health struggles since her diagnosis in 2023, undergoing multiple surgeries, radiation, and chemotherapy treatments. Her passing has prompted an outpouring of tributes from colleagues and friends across the political spectrum.

Born on October 31, 1966, in Etobicoke, Ontario, Duncan was elected five times as the Liberal Member of Parliament for the Toronto riding of Etobicoke North, serving from 2008 until she chose not to run again in the 2025 federal election. Ontario Premier Doug Ford expressed his condolences on social media, stating, “I was deeply saddened to hear of the passing of my friend Kirsty Duncan, a devoted public servant and a champion for the people of Etobicoke North.”

During a news conference in Toronto, Ford noted their long-standing friendship, saying, “People don’t know this, but our family had a rule: we’d never run against Kirsty.” Members of Parliament observed a moment of silence in Duncan’s memory after Liberal MP Kevin Lamoureux announced her death in the House of Commons. Deputy Speaker John Nater remarked that Duncan’s contributions would not be forgotten, highlighting her hard work, courage, and kindness.

Former Prime Minister Justin Trudeau remembered Duncan as someone who was “curious, generous, and deeply committed to helping others.” He added, “She believed in knowledge, compassion, and service, and she brought those values into every conversation and every fight she took on.”

Duncan’s political career saw her serve in various cabinet roles, including Minister of Science from 2015 to 2019 and Minister of Sport from 2018 to 2019. She briefly held the position of Minister for Persons with Disabilities in 2018. After the 2019 election, she became the deputy government House leader until 2021. Despite her medical leave beginning on January 26, 2023, she continued to fulfill her duties as an MP.

Her tenure as Minister of Sport was marked by a strong focus on safe sport initiatives. During a Heritage committee hearing on June 15, 2023, Duncan advocated for significant reforms to eliminate abuse in sports. “We must do everything in our power to address the many, many years of abuse—emotional, physical, psychological, sexual, and verbal abuse,” she stated, urging for a national inquiry into the issue.

Under her leadership, the government established a national toll-free confidential helpline for victims of abuse in sports and announced plans for a comprehensive code of conduct. In the 2019 federal budget, $30 million was allocated over a five-year period to support safe sport initiatives, although her ministry was subsequently merged into the Heritage department.

Duncan was a lifelong athlete, having competed as a gymnast and later as a dedicated runner. She completed the Boston Marathon multiple times and participated in half-Ironman triathlons. Her commitment to physical fitness extended beyond her own pursuits; she served as a coach, dance teacher, and athletics judge, advocating for sports that foster healthy environments for participants.

Academically, Duncan held a doctorate in geography from the University of Edinburgh and taught meteorology, climatology, and climate change at the University of Windsor from 1993 to 2000. She authored the book “Hunting the 1918 Flu: One Scientist’s Search for a Killer Virus” in 2003, based on her research into the origins of the Spanish flu virus. As a member of the Intergovernmental Panel on Climate Change, she contributed to work that earned a Nobel Prize in 2007.

Duncan was known for her commitment to science and public service. In her role as Minister of Science, she focused on enhancing scientific integrity within government, famously stating that her administration “unmuzzled our scientists.” She also reinstated the long-form census, emphasizing the importance of data-driven decision-making.

In her final public remarks during the June 2023 committee hearing, Duncan shared her own experiences with cancer, stating, “To those living with cancer, know that you’re not alone and I stand with you.” She expressed gratitude for the advancements in medicine and the care provided by health professionals.

Kirsty Duncan’s legacy as a dedicated politician, advocate for safe sport, and committed scientist will be remembered by many. Her contributions to Canadian society and her unwavering spirit in the face of adversity have left a lasting impact.
