Tom Siddon, the former Canadian cabinet minister who played a key role during some of the country’s most defining political moments, has died at the age of 84.
His daughter, Katie Siddon Karn, confirmed that Siddon passed away on June 28, 2026. In a heartfelt tribute, she remembered her father as an intelligent leader, bridge-builder and devoted family man who dedicated much of his life to public service.
Born in Drumheller, Alberta, on November 9, 1941, Siddon was trained as an aerospace engineer before entering politics. After serving as a city councillor in Richmond, British Columbia, he was elected to Canada’s House of Commons in 1978 and went on to serve five consecutive terms as a Member of Parliament.
