Kirsty Duncan, a former Liberal cabinet minister and longtime Member of Parliament, has died at the age of 59 after a long battle with cancer. Duncan served Canadians for nearly two decades and built a career that bridged science, education, and public service.
Born on Oct. 31, 1966, Duncan represented the Toronto riding of Etobicoke North. Voters elected her five times between 2008 and 2025. She earned respect across party lines for her commitment to research, fairness, and community work.
Years in Cabinet and Parliament
Duncan joined the cabinet during the first term of former Prime Minister Justin Trudeau. She served as minister of science and sport and later took on the role of minister for persons with disabilities.
Although she spent less than two years in the sport portfolio, she placed strong focus on athlete safety. She continued to speak out on safe sport issues even after leaving that role. Colleagues often described her as determined and deeply principled.
In January 2023, Duncan took a medical leave but continued her duties as a Member of Parliament. She later chose not to seek re-election.
A Career Rooted in Knowledge
Before entering politics, Duncan worked as a teacher, scientist, and athlete. Her academic work earned international recognition, including leadership of an Arctic expedition that explored the origins of the 1918 influenza pandemic. She also helped shape Canadian research in meteorology, climatology, and climate change.
Her background guided her work in government, where she pushed for evidence-based decision-making and stronger support for research and innovation.
Tributes from Political Leaders
Prime Minister Mark Carney extended condolences to Duncan’s family and colleagues on Monday.
"Kirsty’s life was defined by kindness and service," Carney said.
"Before public office, she was a teacher and a scientist… Her contributions to Parliament gave science and research a clearer, louder voice in our democracy. Her curiosity and generosity inspired Canadians across the country."
Trudeau also shared his grief, calling Duncan a close friend.
"I was heartbroken by the loss of Kirsty," he said.
"She believed in knowledge, compassion, and service… I’ll miss her greatly. My thoughts are with her family, her friends, and all those whose lives she touched."
Ontario Premier Doug Ford also offered condolences, praising her dedication to Etobicoke North and her commitment to public service.
Parliament Pays Its Respects
The House of Commons honored Duncan with a moment of silence on Monday. Assistant Deputy Speaker John Nater asked members to rise in her memory.
"I know those of us who had the privilege of serving with her in this place will never forget her hard work, her courage, her compassion, and, above all, her kindness," Nater said.
A Lasting Legacy
Kirsty Duncan leaves behind a legacy shaped by learning, empathy, and service. From science labs to Parliament Hill, she dedicated her life to helping others and strengthening public understanding.
