Michelle O'Bonsawin (born May 2, 1974) is a Canadian jurist who is serving as a puisne justice on the Supreme Court of Canada since 2022.
[7] O'Bonsawin worked as in-house counsel for Canada Post for nine years before she joined the Royal Ottawa Health Care Group in 2009.
[15][16] In 2018, the Court of Appeal for Ontario overturned her decision, ruling that she had improperly expanded the duty in a manner not directly linked to the performance of the contract and limited an expressly bargained-for right.
[19] On August 19, 2022, Prime Minister Justin Trudeau nominated O'Bonsawin to the Supreme Court of Canada to replace retiring Justice Michael Moldaver.
[20] On August 24, O'Bonsawin appeared for a special meeting with the Standing Committee on Justice and Human Rights to answer questions from parliamentarians from both the House of Commons and Senate.
[4] On August 26, 2022, the Office of the Prime Minister announced that her appointment was formally confirmed and she would join the Supreme Court on September 1, 2022, the same day that Moldaver was retiring.
