On Friday, Canadian Prime Minister Justin Trudeau nominated Indigenous Justice Michelle O’Bonsawin to the Supreme Court. This choice, unprecedented in the history of the country, is part of a process of reconciliation between Canadians and their Aboriginal peoples.

A member of the Odanak First Nation in Quebec, the judge has been a member of the Ontario Superior Court of Justice since 2017 and speaks French and English. “I am pleased to announce the appointment of Justice Michelle O’Bonsawin to the Supreme Court of Canada, a body recognized around the world for its strength, excellence and independence,” Trudeau said in a statement.

O’Bonsawin has specialized in a number of areas during his career, including mental health and human rights. “As an Indigenous woman growing up in Northern Ontario, I saw the need for people who are dedicated to raising their voices to represent those who cannot speak for themselves,” said she writes in her application letter published by the government.

Justice Minister David Lametti voiced his support, calling the decision “a historic moment for the (Supreme Court of Canada) and for all of Canada,” on Twitter.

The decision comes as Canada seeks to address the representation of Indigenous peoples in its prisons. Indigenous adults make up 5% of the country’s total population, but 30% of its federal prison population.

The Supreme Court of Canada has nine justices, including a Chief Justice, and members can serve for up to 75 years. A nonpartisan advisory board recommends candidates, but judges are appointed by the government.
