It is with profound sadness that we announce the passing of Adele Kathleen Dion on Wednesday, October 7, 2026. Adele passed away peacefully in hospital at the age of 77, with family at her side.
Adele was born in Fort Frances, Ontario, on March 24, 1949. Predeceased by her cherished parents, Joseph Eugene (Gene) Dion and Eva Marie Dion (née Mathieu).
Adele was the beloved spouse of Martin Andrew (Andy) Nimmo, the loving sister of Janet (Jerry) Gaudry, Rene (Lusia) Dion, Louis (Josie) Dion, and a dear aunt to her nieces and nephews. She is also fondly remembered by the Nimmo family and many friends and former colleagues.
A devoted spouse to Andy, Adele enjoyed travelling with him to her various postings, and they both maximized every opportunity to explore the world. She possessed a keen intelligence, an avid curiosity, and a deep appreciation for others. She will be greatly missed.
Adele was a proud and devoted public servant. She joined the Department of External Affairs in 1972 and served abroad in Moscow, London, and Washington, D.C. In 2001, Adele was appointed Ambassador to the Republic of Finland, and upon her return to Headquarters at the Department of Foreign Affairs (formerly External Affairs), she occupied progressively senior roles. In 2009, while serving as director general of the Human Rights and Democracy Bureau, she was appointed High Commissioner to the Republic of South Africa. After 39 years in the public service and an impressive and accomplished career, Adele retired in 2012.
