The chief justice of Canada () is the presiding judge of the nine-member Supreme Court of Canada, the highest judicial body in Canada. As such, the chief justice is the highest-ranking judge of the Canadian court system. The Supreme Court Act makes the chief justice, a Crown in Council appointment, meaning the Crown acting on the advice of the prime minister and minister of justice. The chief justice serves until they resign, turn 75 years old, die, or are removed from office for cause. By tradition, a new chief justice is chosen from among the court's incumbent puisne justices. The chief justice has significant influence in the procedural rules of the Court, presides when oral arguments are held, and leads the discussion of cases among the justices. The chief justice is also deputy governor general, ex-officio chairman of the Canadian Judicial Council, and heads the committee that selects recipients of the Order of Canada. Additionally, a chief justice also assumes the role of Administrator of Canada and exercises the viceregal duties of the governor general upon the death, resignation or incapacitation of the governor general. Richard Wagner has served as the current chief justice of Canada since 2017. Since the Supreme Court was established in 1875, 18 people have served as chief justice. The court's first chief justice was William Buell Richards; Beverley McLachlin is the longest serving Canadian chief justice (), and was the first woman to hold the position. Appointment The chief justice is appointed by the Governor in Council under the Supreme Court Act on the advice of the prime minister. The appointment is subject to the Supreme Court Act, which governs the administration and appointment of judges of the court. By this component of the Constitution of Canada, Judges appointed to the court must be "a judge of a superior court of a province or a barrister or advocate of at least ten years standing at the bar of a province." Tradition dictates that the chief justice be appointed from among the court's puisne judges; in the history of the Court, only two were not: William Buell Richards, and Charles Fitzpatrick. It is also customary that a new chief justice be chosen alternately from among: the three justices who by law must be from Quebec (with its civil law system), and the other six justices from the rest of Canada (representing the common law tradition).
