# List of justices of the Supreme Court of Canada by court composition

The Supreme Court of Canada (French: Cour suprême du Canada), the highest court of Canada, and the final court of appeals in the Canadian justice system, is composed of nine justices—a chief justice and eight puisne judges—appointed by the Governor General-in-Council. Altogether, 88 persons have served on the Court since it was created in 1875; during this time there have been 18 chief justices.
The graphical timeline below lists the justices of the Supreme Court of Canada by court composition. As Supreme Court historians categorize eras in the court's history by the name of the presiding chief justice, the timeline is divided into sections, according to who was chief justice at the time. The incumbent puisne justices at the start of each court era are listed in order of their seniority at that time. Justices joining the Court during an era are listed below them in the order of their appointment. The bars are colour-coded to show the changes in seniority among the justices during each era.
