Canada is preparing to install former Supreme Court justice and international human rights figure Louise Arbour as the country’s new Governor General on Monday, June 8, 2026, during an official ceremony at the Senate of Canada Building in Ottawa.

The ceremony is scheduled to begin at 10 a.m. Eastern Time and will mark Arbour’s formal entry into one of Canada’s most symbolic constitutional roles, as the representative of King Charles III in Canada.

Arbour brings to the position a long and distinguished career in Canadian law, international justice, and human rights. She previously served as a justice of the Supreme Court of Canada, as Chief Prosecutor for the International Criminal Tribunals for the former Yugoslavia and Rwanda, and as the United Nations High Commissioner for Human Rights.

She will become Canada’s 31st Governor General since Confederation and the first Canadian Governor General appointed after King Charles III’s accession to the throne. She succeeds Mary Simon, who made history as the first Indigenous person to hold the role.

According to the official program, the ceremony will include the swearing-in of the new Governor General, the presentation of Canadian honours and the Great Seal of Canada, and an address by Prime Minister Mark Carney. Arbour is also expected to deliver her first speech to Canadians as Governor General.

Following the ceremony, Arbour will proceed to the National War Memorial in Ottawa, where she will inspect a guard of honour and lay flowers in tribute to Canadians who died in combat. This will be her first official engagement as Governor General and Commander-in-Chief of Canada.

The appointment carries both constitutional and symbolic weight at a time when Canada continues to look for public figures who can represent the country’s democratic institutions, legal traditions, and international commitments. Arbour’s career places her at the intersection of Canadian justice, global accountability, human rights, and institutional reform.

The ceremony will be broadcast live on television, as well as through Canadian Heritage’s YouTube channel and CPAC.

Verification sources: Canadian Heritage confirmed the June 8 installation ceremony at the Senate of Canada Building, including the oath, the Great Seal of Canada, and Arbour’s first address. The Office of the Governor General also confirmed the Rideau Hall arrival and guard of honour following the ceremony.
