Section 20 of the Constitution Act, 1867

Royal Proclamation which brought the Act into force on July 1, 1867

Section 20 of the Constitution Act, 1867 (French: article 20 de la Loi constitutionnelle de 1867) is a repealed provision of the Constitution of Canada, which required annual sittings of the Parliament of Canada. It was repealed in 1982 and replaced by a similar provision in the Canadian Charter of Rights and Freedoms.

The Constitution Act, 1867 is the constitutional statute which established Canada. Originally named the British North America Act, 1867, the Act continues to be the foundational statute for the Constitution of Canada, although it has been amended many times since 1867. It is now recognised as part of the supreme law of Canada.
