Canadian federalism involves the current nature and historical development of the federal system in Canada.
The legal system of Canada is pluralist: its foundations lie in the English common law system, the French civil law system, and Indigenous law systems developed by the various Indigenous Nations.
The Constitution Act, 1867, originally enacted as the British North America Act, 1867, and referred to as the BNA Act or the Act, is a major part of the Constitution of Canada. The Act created a federal dominion and defines much of the operation of the Government of Canada, including its federal structure, the House of Commons, the Senate, the justice system, and the taxation system. The British North America Acts, including this Act, were renamed in 1982 with the patriation of the Constitution ; however, it is still known by its original name in United Kingdom records. Amendments were also made at this time: section 92A was added, giving provinces greater control over non-renewable natural resources.
Pith and substance is a legal doctrine in Canadian constitutional interpretation used to determine under which head of power a given piece of legislation falls. The doctrine is primarily used when a law is challenged on the basis that one level of government has encroached upon the exclusive jurisdiction of another level of government.

The composition of the Court can only be changed by a unanimous constitutional amendment, passed by the two houses of Parliament, and all of the provincial legislative assemblies.
