Canadian Constitutional law

Canadian constitutional law is the area of Canadian law relating to the interpretation and application of the Constitution of Canada by the courts. All laws of Canada, both provincial and federal, must conform to the Constitution and any laws inconsistent with the Constitution have no force or effect.

In Reference re Secession of Quebec, the Supreme Court characterized four fundamental and organizing principles of the Constitution (though not exhaustive): federalism; democracy; constitutionalism and the rule of law; and respect for minorities.

Under the authority of section 52(1) of the Constitution Act, 1982, courts may review all matters of law. Accordingly, the courts have a broad reaching scope of competence. Constitutional issues come before the court through disputes between parties as well as through reference questions. The court has the discretion to hear any Constitutional issues as long as there is a sufficient legal component. The US constitutional political questions doctrine was rejected and so a political dimension to the issue does not bar it from court.

Courts must be careful when considering reference questions. They are required to be careful to only answer questions that are not speculative, of a purely political nature, or unripe. When answering the questions the court must retain its proper role within the constitutional framework.

A party must have standing (locus standi) to bring a constitutional challenge to the courts. Those who wish to challenge a law can do so in one of several ways. A party who is directly affected by the law that purports to be unconstitutional has standing . Likewise, rights holder may challenge any law that will limit any of their rights. Those who are not protected by a right but are nonetheless prosecuted by that law may challenge it as well.
