The Honourable Louise Arbour is a distinguished Canadian jurist whose career has spanned academia, the judiciary, international criminal law, and global human rights leadership. Born in Montréal, Québec, she studied at Collège Régina Assumpta and earned her LL.L. from the Université de Montréal in 1970. She later completed graduate studies at the University of Ottawa while clerking at the Supreme Court of Canada for the Honourable Justice Louis-Philippe Pigeon. She was called to the Québec Bar in 1971 and to the Ontario Bar in 1977.
Ms. Arbour began her career as a Research Officer at the Law Reform Commission of Canada, from 1972 to 1973, then joined Osgoode Hall Law School at York University, where she taught and later became Associate Dean, gaining recognition for her scholarship in criminal law, public law, and civil liberties.
Her judicial career began in 1987 with her appointment to the Supreme Court of Ontario. Three years later, she was appointed to the Court of Appeal for Ontario. In 1995, she led the Commission of Inquiry into events at the Prison for Women in Kingston. The Commission’s 1996 report became a landmark in Canadian corrections, reinforcing the rule of law and shaping long-term reforms, particularly for women’s institutions.
From 1996 to 1999, Ms. Arbour served as Chief Prosecutor for the International Criminal Tribunals for the former Yugoslavia and Rwanda. In this role, she strengthened the tribunals’ effectiveness through innovations such as sealed indictments and advanced enforcement efforts, including the indictment of Serbian President Slobodan Milošević – the first of a sitting head of state by an international tribunal. Her tenure also contributed to major jurisprudential advances, including recognition in international law that sexual violence can constitute an act of genocide and a crime against humanity.
Ms. Arbour was appointed to the Supreme Court of Canada in 1999 and served until 2004, contributing to important decisions in constitutional and criminal law and advancing a principled approach to the interpretation of the Canadian Charter of Rights and Freedoms.
From 2004 to 2008, Ms. Arbour was United Nations (UN) High Commissioner for Human Rights, focusing on accountability, institutional reform, and strengthening global human rights mechanisms. She later served as President and Chief Executive Officer of the International Crisis Group from 2009 to 2014 and as Special Representative of the UN Secretary-General for International Migration from 2017 to 2018, helping guide global migration policy.
From 2021 to 2022, Ms. Arbour led an independent review of Canada’s Department of National Defence and the Canadian Armed Forces, where she recommended wide-ranging reforms to address sexual misconduct and institutional culture.
In recognition of her contributions, Ms. Arbour has received numerous awards and recognitions, including the Tang Prize in Rule of Law and the O’Connor Justice Prize, and holds 42 honorary doctorates from universities in Canada and abroad. She is a Companion of the Order of Canada and a Grande officière de l’Ordre national du Québec.
As of 2026, Ms. Arbour serves as Senior Counsel at Borden Ladner Gervais (BLG) while undertaking some philanthropic work with different organisations.
