Canadian federalism involves the current nature and historical development of the federal system in Canada.
The Constitution Act, 1867, originally enacted as the British North America Act, 1867, is a major part of the Constitution of Canada.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. In 1982, with the patriation of the Constitution, the British North America Acts which were originally enacted by the British Parliament, including this Act, were renamed. However, the acts are still known by their original names in records of the United Kingdom. Amendments were also made at this time: section 92A was added, giving provinces greater control over non-renewable natural resources.
The court system of Canada forms the country's judiciary, formally known as "The King on the Bench", which interprets the law and is made up of many courts differing in levels of legal superiority and separated by jurisdiction. Some of the courts are federal in nature, while others are provincial or territorial.
Russell v R is a Canadian constitutional law decision dealing with the power of the federal Parliament. The case was decided by the Judicial Committee of the Privy Council, at that time the highest court in the British Empire, including Canada. The Judicial Committee held that the Canada Temperance Act was valid federal legislation under the peace, order and good government power, set out in section 91 of the Constitution Act, 1867. The case expanded upon the jurisprudence that was previously discussed in Citizen's Insurance Co. v. Parsons.

Ontario (AG) v Canada (AG), also known as the Local Prohibition Case, is a significant Canadian constitutional decision by the Judicial Committee of the Privy Council, at that time the highest court in the British Empire, including Canada. It was one of the first cases to enunciate core principles of the federal peace, order and good government power.
The Canada Temperance Act, also known as the Scott Act, was an Act of the Parliament of Canada passed in 1878, which provided for a national framework for municipalities to opt in by plebiscite to a scheme of prohibition. It was repealed in 1984.
The Double aspect doctrine in Canadian constitutional law is one that allows for laws to be created by both provincial and federal governments in relation to the same subject matter. Typically, the federalist system assigns subject matters of legislation to a single head of power. However, certain matters have several dimensions to them, such that for one purpose the matter will fall to one head of power, while for another purpose, it will fall to the other. For example, highway traffic laws fall into the property and civil rights power of the province, but equally, can be a criminal offence which is in the criminal law power of the federal government.
R v Hauser, [1979] 1 S.C.R. 984 is a leading constitutional decision of the Supreme Court of Canada, where, In a four to three decision, the Court upheld the federal Narcotic Control Act as constitutional under the peace, order and good government power. This case is particularly unusual as the Act had previously held to be constitutional under the Criminal law power in the decision of Industrial Acceptance Corp. v. The Queen [1953] 2 S.C.R. 273.

Crevier v Quebec (AG), [1981] 2 S.C.R. 220 is a leading Supreme Court of Canada decision in administrative law. The court had to decide whether a Quebec-created Professionals Tribunal was unconstitutional due to being a "s. 96 court" according to the Constitution Act, 1867, whose members can only be federally appointed. It found that any legislation which has a privative clause purporting to exclude review of jurisdictional matters is outside the jurisdiction of a provincial legislature.
Loss of rights due to criminal conviction refers to the practice in some countries of reducing the rights of individuals who have been convicted of a criminal offence. The restrictions are in addition to other penalties such as incarceration or fines. In addition to restrictions imposed directly upon conviction, there can also be collateral civil consequences resulting from a criminal conviction, but which are not imposed directly by the courts as a result of the conviction.
