List of Puisne Justices of the Supreme Court of Canada

The Supreme Court of Canada is the highest court of Canada. It was created in 1875 by a law passed by the Parliament of Canada, the Supreme and Exchequer Court Act. Since 1949, the Court has been the final court of appeal in the Canadian justice system. Originally composed of six justices (the Chief Justice of Canada and five puisne justices), the Court was expanded to seven justices by the creation of an additional puisne justice position in 1927, and then to nine justices by the creation of two more puisne justice positions in 1949.

The justices are appointed by the Governor-in-Council (Governor General of Canada on the advice of the Cabinet). The first six justices of the Court were all appointed in 1875 by the then Governor General of Canada, the Earl of Dufferin, on the advice of the Canadian Prime Minister, Alexander Mackenzie.

Of the nine justices, three positions are required by law to be held by judges who are either judges of the superior courts of Quebec, or members of the Bar of Quebec, at the time of their appointment. Traditionally, three of the remaining judges are appointed from Ontario, two from the four western provinces, and one from the Atlantic provinces. The judges from these provinces, other than Quebec, must have been a judge of a superior court, or a member of the bar of one of those provinces for ten or more years prior to the appointment. A Supreme Court justice, as with all federal judges, has guaranteed tenure during good behaviour, and may sit on the bench until the age of 75 years.Beverley McLachlin is the current Chief Justice and is the first woman to hold this position.
