The jurisdiction of a Master is fixed by provincial statute and the rules of court. Masters are appointed by the provincial government. As a result, while Masters sit in a superior court, they do not have the "inherent jurisdiction" of the judges of those courts, who are appointed by the federal government and whose authority is derived from the Constitution of Canada and the Crown. Their jurisdiction is usually limited to procedural and Interlocutory matters heard in chambers. Consequently, though of the superior court, Masters are concurrently subordinate to the judges of that court insofar as application of judicial precedent is concerned. Masters commonly also sit as Registrars in Bankruptcy.
