Section 94 of the Constitution Act, 1867

At the time of Confederation, some of the Fathers of Confederation envisaged a highly centralised federal government. John A. Macdonald, a leading figure in the Confederation negotiations and the first prime minister of Canada, was a particular proponent of centralisation.^[3] Section 94 is an example of that approach, as it would allow the federal Parliament to assume jurisdiction over property and civil rights, which is normally a matter of exclusive provincial jurisdiction under section 92(13) of the Constitution Act, 1867,^{[8]: 270–275} and over procedure in the civil courts, which is a matter of provincial jurisdiction under section 92(14).^{[8]: 275–279} The provinces in question would first have to agree to the federal legislation, but after that, the matters covered by the legislation would be permanently transferred to federal jurisdiction.

The provision applies in the three original common law provinces: New Brunswick, Nova Scotia, and Ontario. It does not give the federal Parliament the power to assume jurisdiction over property and civil rights in Quebec, which uses a civil law system, nor court procedure in that province.

The provision has never been used. In 1869 the federal government of Prime Minister Macdonald appointed a commission to study a uniform bill. The commissioner, John Hamilton Gray, former premier of New Brunswick, gave his report in 1871, with suggestions for a draft uniform bill, but Parliament did not proceed with it.^{[9]: 528–529} The matter was raised again in the House of Commons some 30 years later, when a Liberal backbencher, Benjamin Russell made a proposal to apply section 94. The matter was debated in the House of Commons, and strongly opposed by the Liberal minister of justice, Charles Fitzpatrick, who sarcastically commented that the first step in considering the matter "would be to ask the local legislatures how soon they are going to be disposed to commit suicide",^[9]: 529 a comment on the significance of the provincial jurisdiction over property and civil rights.

One noted constitutional scholar, F.R. Scott, has argued that the provinces did actually cede their jurisdiction over labour relations by agreeing to apply the federal Industrial Disputes Investigation Act, even though neither the federal Parliament nor the provincial legislatures referred to any transfer of jurisdiction. Scott acknowledged that no court had ever considered the possibility.^{[9]: 537–543}

One other point is the scope of section 94. On its face, it only applies to the three original common law provinces, New Brunswick, Nova Scotia, and Ontario. Scott argued that by the nature of the provision, to create federal uniform jurisdiction, it should be read to include all provinces added to Confederation after 1867. He did acknowledge, however, that the constitutional provisions for the admission of the three Prairie provinces, Alberta, Manitoba and Saskatchewan, each contained clauses that suggested they would only be bound by provisions that applied to all the other provinces, which clearly section 94 did not.^{[9]: 533–535}

Section 92(13) gives the provinces exclusive jurisdiction over property and civil rights. Section 92(14) gives the provinces exclusive jurisdiction over procedure in civil courts.
