Section 91 Of The Constitution Act, 1867

Section 91 of the ''Constitution Act, 1867'' () is a provision in the Constitution of Canada that sets out the legislative powers of the federal Parliament. The federal powers in section 91 are balanced by the list of provincial legislative powers set out in section 92 of the ''Constitution Act, 1867''. The dynamic tension between these two sets of legislative authority is generally known as the "division of powers". The interplay between the two lists of powers have been the source of much constitutional litigation since the Confederation of Canada in 1867.

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.

''Constitution Act, 1867''

The ''Constitution Act, 1867'' is part of the Constitution of Canada and thus part of the supreme law of Canada. It was the product of extensive negotiations by the governments of the British North American provinces in the 1860s. The Act sets out the constitutional framework of Canada, including the structure of the federal government and the powers of the federal government and the provinces. Originally enacted in 1867 by the British Parliament under the name the ''British North America Act, 1867'', in 1982 the Act was brought under full Canadian control through the Patriation of the Constitution, and was renamed the ''Constitution Act, 1867''. Since Patriation the Act can only be amended in Canada, under the amending formula set out in the ''Constitution Act, 1982''.''Constitution Act, 1982'', Part V.

Text of section 91

Section 91 reads:

Section 91 is found in Part VI of the ''Constitution Act, 1867'', dealing with the distribution of legislative powers between the federal and provincial governments.

Amendments

Section 91 has been amended three times since 1867.

When the Act was enacted in 1867, "The Public Debt and Property" was listed as section 91(1), and stayed in that position until 1949. In that year the British Parliament, on the request of the Canadian Senate and House of Commons, passed an amendment to the Act which re-numbered "The Public Debt and Property" as section 91(1A), and enacted a new version of section 91(1). That new provision authorised the federal Parliament to enact certain limited types of constitutional amendments, relating to the internal structure of the federal government.

That version of s. 91(1) was repealed in 1982 on the enactment of the ''Constitution Act, 1982'', which contains a comprehensive amending formula. Section 44 of that Act is the equivalent to the repealed version of s. 91(1), authorising limited amendments to the internal structure of the federal government.

Section 91 was also amended in 1940 by the addition of section 91(2A), "Unemployment insurance". That provision was added by the British Parliament on the request of the Senate and House of Commons, after unanimous agreement from the provincial governments. The amendment responded to the 1937 decision of the Judicial Committee of the Privy Council, the highest court for the British Empire, which had struck down an attempt by the federal government to pass unemployment insurance in response to the Great Depression. The Judicial Committee ruled that unemployment insurance was a matter of exclusive provincial jurisdiction. The new section 91(2A) instead assigned that jurisdiction to the federal Parliament.

Background and interpretation

The interplay between the list of federal powers in section 91, and the corresponding list of provincial powers in section 92, has been one of the most heavily litigated issues since Confederation in 1867. The relationship between the federal and provincial powers is generally referred to as the "division of powers", meaning federalism issues, not separation of powers.

Both the federal powers and the provincial powers are stated to be exclusive, not concurrent. A subject matter which falls within federal jurisdiction therefore does not come within provincial jurisdiction, and ''vice versa''. Canadian constitutional analysis uses the term ''ultra vires'' as shorthand for a matter that is outside the jurisdiction of a government, and ''intra vires'' for a matter that is within the jurisdiction of a government. Related constitutional doctrines such as paramountcy and inter-jurisdictional immunity are also used to assess the constitutionality of a law under the division of powers.

Although some of the Fathers of Confederation, such as John A. Macdonald, favoured a strong central government, other Fathers of Confederation, such as Oliver Mowat, were more inclined to broader provincial powers. Quebec has traditionally favoured stronger provincial powers. In the late 19th century and early 20th century, the Judicial Committee of the Privy Council issued a series of decisions which expanded provincial powers at the expense of federal powers.

Additional sources of federal jurisdiction

Section 91 is not the only source of federal legislative authority, as there are other provisions of the ''Constitution Act, 1867'' which confer legislative power on the federal Parliament:

* section 41 gives Parliament jurisdiction over the conduct of federal elections;

* section 91(29), when combined with the exceptions from provincial jurisdiction in section 92(10), gives Parliament jurisdiction over international and interprovincial works and undertakings, interprovincial and international shipping, and works declared by Parliament to be for the greater advantage of Canada;

* section 93(4) gives Parliament an exceptional jurisdiction to protect denominational and separate school rights;

* section 94 gives Parliament the power to legislate for uniform property and civil rights, if the provinces of Ontario, New Brunswick and Nova Scotia choose to transfer that jurisdiction to Parliament;

* section 94A gives Parliament the power to legislate on old age pensions and supplemental benefits, concurrent with provincial jurisdiction;

* section 95 gives Parliament the power to legislate with respect to agriculture and immigration, concurrent with provincial jurisdiction;

* section 101 gives Parliament the power to establish a "general court of appeal for Canada", as well as courts "for the better administration of the laws of Canada".''Constitution Act, 1867'', s. 101.

In addition, section 44 of the ''Constitution Act, 1982'' gives Parliament the power to legislate for the internal legislative and executive structure of the federal government.
