The Constitution Act, 1867 (originally enacted as The British North America Act, 1867, and referred to as the BNA Act), is a major part of Canada's Constitution. 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 The British North America Acts, including this Act, were renamed in 1982 with the patriation of the Constitution (originally enacted by the British Parliament); however, it is still known by its original name in United Kingdom records.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.
