Section 53 of the Constitution Act, 1867

Section 53 of the Constitution Act, 1867 (French: article 53 de la Loi constitutionnelle de 1867) is a provision of the Constitution of Canada relating to taxation and appropriation statutes, which are under the control of the House of Commons, the lower house of the Parliament of Canada.

The requirement in section 53 also applies indirectly to the provinces. Section 90 of the act provides that the provision respecting taxation and appropriations also applies in the provincial legislatures.

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.
