Prime Minister Mark Carney has named Louise Arbour as Canada’s next governor general.
Arbour will replace Mary Simon later this year, pending formal approval by King Charles III.
Arbour is a former justice of the Supreme Court of Canada. She also served as the United Nations High Commissioner for Human Rights and as a war crimes prosecutor.
Carney said the role of governor general remains central to Canada’s constitutional system, describing it as “the guardian of our constitutional order.” He said the position requires “sound judgment, deep learning, and an unwavering commitment to the rule of law.”
She becomes the 31st governor general since Confederation.
“I am fully aware of the responsibility that I am about to take on,” Arbour said. “I will strive to serve with honour, dedication, and integrity.”
She said Canada is “shaped by its diversity of people, of perspectives and experiences, but also by a common respect for strong public institutions and for the rule of law.”
Arbour said she is taking on the role “with a deep sense of duty” as Canadians face “complexity and change,” adding that trust and cooperation will be essential.
“The strength of our country resides in stable institutions,” she said.
Carney said Arbour brings strong legal experience and international credibility.
Her appointment comes as the federal government faces ongoing questions about institutional trust and national unity.
Arbour is fully bilingual. Her fluency in English and French is expected to be important, especially in Quebec.
She previously led a review into misconduct in the Canadian Armed Forces and called for major reforms.
Arbour is expected to be sworn in later this year.
