Powers of the National and Provincial Governments
education (subject to certain rights of the Protestant and Roman Catholic minorities in some provinces).
Of course the power to amend provincial constitutions is restricted to changes in the internal machinery of the provincial government. Provincial legislatures are limited to the powers explicitly given to them by the written Constitution. So no provincial legislature can take over powers belonging to the Parliament of Canada. Nor could any provincial legislature pass an Act taking the province out of Canada. No such power is to be found in the written Constitution, so no such power exists.
Similarly, of course, Parliament cannot take over any power of a provincial legislature.
Parliament and the provincial legislatures both have power over agriculture and immigration, and over certain aspects of natural resources; but if their laws conflict, the national law prevails.
Parliament and the provincial legislatures also have power over old age, disability and survivors’ pensions; but if their laws conflict, the provincial power prevails.
By virtue of the Constitution Act, 1867, everything not mentioned as belonging to the provincial legislatures comes under the national Parliament.
This looks like an immensely wide power. It is not, in fact, as wide as it looks, because the courts have interpreted the provincial powers, especially “property and civil rights,” as covering a very wide field. As a result, all labour legislation (maximum hours, minimum wages, safety, workers’ compensation, industrial relations) comes under provincial law, except for certain industries such as banking, broadcasting, air navigation, atomic energy, shipping, interprovincial and international railways, telephones, telegraphs, pipelines, grain elevators, enterprises owned by the national government, and works declared by Parliament to be for the general advantage of Canada or of two or more of the provinces.
Social security (except for Employment Insurance, which is purely national, and the shared power over pensions) comes under the provinces. However, the national Parliament, in effect, established nation-wide systems of hospital insurance and medical care by making grants to the provinces (or, for Quebec, yielding some of its field of taxes) on condition that their plans reach certain standards. The courts’ interpretation of provincial and national powers has put broadcasting and air navigation under Parliament’s general power to make laws for the “peace, order and good government of Canada,” but otherwise has reduced it to not much more than an emergency power for wartime or grave national crises like nation-wide famine, epidemics, or massive inflation (though some recent cases go beyond this).

A 1940 constitutional amendment gave Parliament exclusive power over Unemployment Insurance (now known as Employment Insurance) and a specific section of the Act of 1867 gives it power to establish courts “for the better administration of the laws of Canada.” This has enabled Parliament to set up the Supreme Court of Canada, the Federal Court of Appeal, the Federal Court and the Tax Court of Canada.
As already noted, the national Parliament can amend the Constitution in relation to the executive government of Canada and the Senate and the House of Commons, except that it cannot touch the office of the Queen or the Governor General, nor those aspects of the Senate and the Supreme Court of Canada entrenched by the amending formulas. Though Parliament cannot transfer any of its powers to a provincial legislature, nor a provincial legislature any of its powers to Parliament, Parliament can delegate the administration of a federal Act to provincial agencies (as it has done with the regulation of interprovincial and international highway traffic); and a provincial legislature can delegate the administration of a provincial Act to a federal agency. This “administrative delegation” is an important aspect of the flexibility of our Constitution.
* The Fathers of Confederation evidently felt that Sable Island, “the graveyard of the Atlantic,” was such a menace to shipping that it must be under the absolute control of the national government, just like lighthouses. So they placed it under the exclusive legislative jurisdiction of the national Parliament (by section 91, head 9, of the Constitution Act, 1867). They also (by the third schedule of that Act) transferred the actual ownership from the Province of Nova Scotia to the Dominion of Canada, just as they did with the Nova Scotia lighthouses.
