The Constitution is Canada's supreme law. Canada has a federal system of government. Authority to make and administer laws is constitutionally divided between the federal government and the governments of the ten provinces and three territories.
Canada’s Constitution is not found in only one document but comprises a series of British and Canadian legislation.
The constitutional documents page on the Department of Justice website includes the Consolidation of Constitution Acts 1867 to 1982 - this consolidation contains the text of the Constitution Act 1867 (formerly the British North America Act, 1867) as amended, and the text of the Constitution Act 1982, as amended. The Constitution Act 1982 contains the Canadian Charter of Rights and Freedoms and other provisions, including the procedure for amending the Constitution of Canada.
