Canadian administrative law is the body of law that addresses the actions and operations of governments and governmental agencies in Canada. That is, the law concerns the manner in which courts can review the decisions of administrative decision-makers (ADMs) such as a board, tribunal, commission, agency or minister.
The body of law is concerned primarily with issues of substantive review (the determination and application of a standard of review) and with issues of procedural fairness (the enforcement of participatory rights). Administrative law concerns the statutes and rules of government operations. Courts ensure that ADMs observe the limits on the authority. Also, declaration and equitable injunction remedies exist.
The powers of an ADM are primarily created by statute, which is known as the "enabling statute". These powers are limited by the legislative authority of the enabling government provided under section 91 or 92 of the Constitution Act, 1867. Superior Courts (known as Section 96 Courts) have an inherent power at common law to review any decision of an ADM. A judicial review allows for the court to consider the entire decision-making process, including the process, the findings of fact and of law. The power of judicial review is found either in the enabling statute or by virtue of the common law. The common law powers are derived from the four original writs of certiorari, prohibition, mandamus, and habeas corpus.
Courts may also review a decision through a statutory appeal when the review power is explicitly granted within the enabling statute that created the administrative body. Appeals are typically reviews for errors of law.
These powers are also frequently limited by privative clauses or finality clauses within the enabling statute. A privative clause will declare the ADMs decision is "final and conclusive" and/or that the ADM has "exclusive jurisdiction" over the matter, effectively removing any power of review. As established in Crevier v. Quebec (1981), the Constitution requires that the courts be able to supervise errors of ADMs and so the legislature cannot completely oust them from that power, nor can an ADM completely replace a Superior Court.
