Overview
- Louise Arbour was sworn in as Canada’s 31st governor general on Monday, June 8, 2026, in the Senate of Canada Building in Ottawa during a ceremony that included the Great Seal transfer, a 21-gun salute and Indigenous welcome rites.
- Prime Minister Mark Carney nominated Arbour and King Charles III approved the appointment, with Arbour meeting the monarch at Buckingham Palace shortly before the installation.
- Arbour’s credentials include service as a judge on Canadian courts, chief prosecutor at the international criminal tribunals for the former Yugoslavia and Rwanda, and United Nations high commissioner for human rights.
- In her maiden viceregal speech Arbour urged peaceful management of differences, warned that extreme polarization and unchecked consensus are dangerous, pushed for reconciliation with Indigenous peoples and cautioned against overreliance on artificial intelligence.
- As the King’s representative Arbour now holds constitutionally important powers—granting Royal Assent, swearing in ministers, summoning or dissolving Parliament and serving as commander-in-chief—which will shape how Canada conducts formal government business and projects national values at home and abroad.
