Section 125 of the Constitution Act, 1867

Proclamation bringing the Constitution Act into force, July 1, 1867

Section 125 of the Constitution Act, 1867 (French: article 125 de la Loi constitutionnelle de 1867) is a provision of the Constitution of Canada relating to taxation immunities of the federal and provincial governments. The section provides that the property of the provincial and federal governments are not subject to taxation.

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.
