Think of a constitution as the first law of the country - the supreme law from which all other laws originate and the law to which all other laws must conform. Canada's Constitution is said to have both written and unwritten features. The written part of Canada's constitution is made up of such documents as the Constitution Act (1867), the federal acts that admitted new provinces since 1867, the Supreme Court Act (1875), the Constitution Act (1982) with its Charter of Rights and Freedoms, and the Emergencies Act (1988).
But like the British constitution which is unwritten, Canada follows many similar constitutional traditions and conventions, such as the role of the Prime Minister and Cabinet in Parliament, the solidarity of the Cabinet, and the function of political parties in Parliament.
