The powers of government are divided between the provinces and the federal government and are described in sections 91 to 95 of the act. Sections 91 and 92 are of particular importance, as they enumerate the subjects for which each jurisdiction can enact a law, with section 91 listing matters of federal jurisdiction and section 92 listing matters of provincial jurisdiction. Sections 92A and 93 and 93A are concerned with non-renewable natural resources and education, respectively (both are primarily provincial responsibilities). Section 94 leaves open a possible change to laws regarding
property and civil rights, which so far has not been realized. Sections 94A and 95, meanwhile, address matters of shared jurisdiction, namely
old age pensions (section 94A) and agriculture and immigration (section 95).
Peace, order and good government Section 91 authorizes
Parliament to "make laws for the peace, order, and good government of Canada, in relation to all matters not coming within the classes of subjects by this act assigned exclusively to the Legislatures of the provinces". Although the text of the act appears to give Parliament residuary powers to enact laws in any area that has not been allocated to the
provincial governments, subsequent Privy Council jurisprudence held that the "peace, order, and good government" power is in a delimited federal competency like those listed under section 91 (see e.g.
AG Canada v AG Ontario (Labour Conventions), [1937] AC 326 (PC)). In 2019, the
Saskatchewan Court of Appeal sided with the federal government in a 3–2 split on the
Greenhouse Gas Pollution Pricing Act, allowing an expansion of the federal government's taxation power over the provinces in the wake of the climate change crisis, concurrently as Parliament joined with other national legislatures in declaring that the nation was in a "
climate emergency" on 17 June. In
Grant Huscroft's dissenting opinion on the
Court of Appeal for Ontario, he provides that "counsel for Canada conceded that the act was not passed on the basis that climate change constitutes an emergency".
First Nations, Inuit and Métis Section 91(24) of the act provides that the federal government has the legislative jurisdiction for "Indians and lands reserved for the Indians".
Aboriginal Affairs and Northern Development Canada (AANDC), formerly known as Indian and Northern Affairs Canada (INAC), has been the main federal organization exercising this authority. This empowered the Canadian government to act as if the treaties between the Indigenous peoples and the British Crown preceding Confederation did not exist. The
Treaty of Niagara of 1764 bound the Crown and the Indigenous peoples of the Great Lakes basin together in a familial relationship, a relationship that exists to this day, exemplified by First Nations attendance at the coronation of
King Charles III. Treaty rights would be incorporated into the 1982 Constitution.
Criminal law Section 91(27) gives Parliament the power to make law related to the "criminal law, except the constitution of courts of criminal jurisdiction, but including the procedure in criminal matters". It was on this authority that Parliament enacted and amends the
Criminal Code. However, under section 92(14), the provinces are delegated the power to administer justice, "including the constitution, maintenance, and organization of provincial courts, both of civil and criminal jurisdictions, and including procedure in civil matters in both courts". This provision allows the provinces to create the courts of criminal jurisdiction and to create provincial police forces such as the
OPP and the
Sûreté du Québec (SQ). As a matter of policy dating back to Confederation, the federal government has delegated the prosecutorial function for almost all criminal offences to the provincial Attorneys General. Crown Prosecutors appointed under provincial law thus prosecute almost all Criminal Code offences across Canada. Section 91(28) gives Parliament exclusive power over "penitentiaries" while section 92(6) gives the provinces powers over the "prisons". This means that offenders sentenced to two years or more go to federal penitentiaries while those with lighter sentences go to provincial prisons.
Property and civil rights Section 92(13) gives the Provinces the exclusive power to make law related to "
property and civil rights in the province". In practice, this power has been read broadly to give the provinces authority over numerous matters such as professional trades,
labour relations, and consumer protection.
Marriage Section 91(26) gives the federal government power over divorce and marriage. On this basis, Parliament can legislate on the substantive law of marriage and divorce. However, the provinces have power over the procedural law governing the
solemnization of marriage (section 92(12)). There are also several instances of overlap in laws relating to marriage and divorce, which in most cases is solved through
interjurisdictional immunity. For instance, the federal
Divorce Act is valid legislation, even though the
Divorce Act has some incidental effects on
child custody, which is usually considered to be within the provincial jurisdictions of "civil rights" (s. 92(13)) and "matters of a private nature" (s. 92(16)).
Works and undertakings Section 92(10) allows the federal government to declare any "works or undertakings" to be of national importance, and thereby remove them from provincial jurisdiction.
Education (Sections 93 and 93A) Sections 93 and 93A give the Provincial Provinces power over the competency of education, but there are significant restrictions designed to protect minority religious rights. This is due that it was created during a time when there was a significant controversy between Protestants and Catholics in Canada over whether schools should be parochial or non-denominational. Section 93(2) specifically extends all pre-existing denominational school rights into the post-Confederation era.
Section 94 Section 94 allows for the provinces that use the British-derived common law system, in effect all but Quebec, to unify their property and civil rights laws. This power has never been used.
Old Age Pensions (Section 94A) Under Section 94A, the federal and provincial governments share power over Old Age Pensions. Either order of government can make laws in this area, but in the case of a conflict, provincial law prevails.
Agriculture and Immigration (Section 95) Under Section 95, the federal and provincial governments share power over agriculture and immigration. Either order of government can make laws in this area, but in the case of a conflict, federal law prevails. == Part VII: Judicature ==
