The Supreme Court of Canada is the highest court in the judicial system of Canada. It comprises nine justices, whose decisions are the ultimate application of Canadian law, and grants permission to between 40 and 75 litigants each year to appeal decisions rendered by provincial, territorial and federal appellate courts. The Supreme Court is bijural, hearing cases from two major legal traditions and bilingual, hearing cases in both official languages of Canada.

In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and high court of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A Supreme Court can also, in certain circumstances, act as a court of original jurisdiction, however, this is typically limited to constitutional law.
