Canadian lawyer

The Canadian legal system has its foundation in the English common law system, inherited from being a former colony of the United Kingdom and later a Commonwealth Realm member of the Commonwealth of Nations. The legal system is bi-jurisdictional, as the responsibilities of public (includes criminal) and private law are separated and exercised exclusively by Parliament and the provinces respectively. Quebec, however, still retains a civil system for issues of private law (as this domain falls within the exclusive jurisdiction of the provinces).

Both legal systems are subject to the Constitution of Canada. The federal government has jurisdiction over certain exclusive domains which are regulated exclusively by Parliament, as well as all matters and disputes between provinces. These generally include interprovincial transport (rail, air and marine transport) as well as interprovincial trade and commerce (which generally concerns energy, the environment, agriculture). Criminal prosecutions are conducted in the style of the British common law, as this jurisdiction falls exclusively to the federal government.

Canada's constitution is its supreme law, and any law passed by any federal, provincial, or territorial government that is inconsistent with the constitution is invalid.

The Constitution Act, 1982 stipulates that Canada's constitution includes that act, a series of thirty acts and orders referred to in a schedule to that act (the most notable of which is the Constitution Act, 1867), and any amendment to any of those acts. However, the Supreme Court of Canada has found that this list is not intended to be exhaustive, and in 1998's Reference re Secession of Quebec identified four "supporting principles and rules" that are included as unwritten elements of the constitution: federalism, democracy, constitutionalism and the rule of law, and respect for minorities. While these principles are an enforceable part of Canada's constitution, Canadian courts have not used them to override the written text of the constitution, instead confining their role to "filling gaps".
