The Powers of Disallowance and Reservation in Canadian federalism

Sections 55, 56, and 57 of the Constitutional Act, 1867, provide for mechanisms and ways by which the Governor-General of Canada may, in the name of the Queen, refuse to assent or reserve bills passed by the Parliament of Canada. Section 90 extends these powers, in so far as the provinces are concerned, to the Lieutenant-Governor and the Federal Government. Since the Statute of Westminster, in 1931, the British government does not disallow federal bills anymore but the provisions permitting the disallowance of provincial acts by the federal government are still in effect although they have fallen into disuse.

The right to disallow provincial acts by the federal government runs contrary to the true principles of federalism as it undermines the concept of the sovereignty of the provinces in their spheres of jurisdiction. The last case of disallowance occurred in 1943 and reservation of provincial legislation by a Lieutenant-Governor last took place in 1937. There now seems to be a convention that these powers will not be used again in the future.

Between 1867 and today, 112 provincial laws were disallowed (68 from 1867-1896, 28 from 1897-1920, 16 between 1921 and today. Disallowance of laws passed by the four western provinces accounts for 76% of all laws disallowed by the federal government. The single most important reason for disallowance of western laws was to support the National Policy. Between 1867 and today, 70 provincial laws were reserved by Lieutenant-Governors for decision by the federal government (57 from 1867-1896, 9 from 1897-1920, and 4 from 1921 to today. Reservation of laws passed by the four western provinces accounts for 52% of all cases of reservation. Many in Western Canada have interpreted the frequent use of both these powers against their region as attempts of "Imperial Canada" to thwart the wishes of the West and to keep their region as subservient to the interests of Central Canada.
