Canadian federalism (French: fédéralisme canadien) involves the current nature and historical development of the federal system in Canada.
Canada is a federation with eleven components: the national Government of Canada and ten provincial governments. All eleven governments derive their authority from the Constitution of Canada. There are also three territorial governments in the far north, which exercise powers delegated by the federal parliament, and municipal governments which exercise powers delegated by the province or territory. Each jurisdiction is generally independent from the others in its realm of legislative authority. The division of powers between the federal government and the provincial governments is based on the principle of exhaustive distribution: all legal issues are assigned to either the federal Parliament or the provincial Legislatures.
The division of powers is set out in the Constitution Act, 1867 (originally called the British North America Act, 1867), a key document in the Constitution of Canada. Some amendments to the division of powers have been made in the past century and a half, but the 1867 Act still sets out the basic framework of the federal and provincial legislative jurisdictions.
The resulting constitution was couched in more centralist terms than intended. As prime minister, Macdonald tried to exploit this discrepancy to impose his centralist ideal against chief opponent Oliver Mowat. In a series of political battles and court cases from 1872 to 1896,[a] Mowat reversed Macdonald's early victories and entrenched the co-ordinated sovereignty which he saw in the Quebec Resolutions. In 1888, Edward Blake summarized that view: "[It is] a federal as distinguished from a legislative union, but a union composed of several existing and continuing entities ... [The provinces are] not fractions of a unit but units of a multiple. The Dominion is the multiple and each province is a unit of that multiple ..." The accession of Wilfrid Laurier as prime minister inaugurated a new phase of constitutional consensus, marked by a more-egalitarian relationship between the jurisdictions. The federal government's quasi-imperial powers of disallowance and reservation, which Macdonald abused in his efforts to impose a centralised government, fell into disuse.
During World War I the federal Crown's power was extended with the introduction of income taxes and passage of the War Measures Act, the scope of which was determined by several court cases.[b] The constitution's restrictions of parliamentary power were affirmed in 1919 when, in the Initiatives and Referendums Reference, a Manitoba act providing for direct legislation by way of initiatives and referendums was ruled unconstitutional by the Privy Council on the grounds that a provincial viceroy (even one advised by responsible ministers) could not permit "the abrogation of any power which the Crown possesses through a person directly representing it".[nb 11] Social and technological changes also worked their way into constitutional authority; the Radio Reference found that federal jurisdiction extended to broadcasting,[nb 12] and the Aeronautics Reference found the same for aeronautics.[nb 13]
World War II's broader scope required passage of the National Resources Mobilization Act to supplement the powers in the War Measures Act to pursue the national war effort. The extent to which wartime federal power could expand was further clarified in the Chemicals Reference (which held that Orders in Council under the War Measures Act were equivalent to acts of parliament)[nb 16] and the Wartime Leasehold Regulations Reference, which held that wartime regulations could displace provincial jurisdiction for the duration of an emergency.[nb 17] Additional measures were required in order to secure control of the economy during that time. Jurisdiction over unemployment insurance was transferred permanently to the federal sphere;[na 3] the provinces surrendered their power to levy succession duties and personal and corporate income taxes for the duration of the war (and for one year afterwards) under the Wartime Tax Rental Agreement; and labour relations were centralized under federal control with the Wartime Labour Relations Regulations (lasting until 1948), in which the provinces ceded their jurisdiction over all labour issues.
Canada emerged from the war with better cooperation between the federal and provincial governments. This led to a welfare state, a government-funded health care system and the adoption of Keynesian economics. In 1951 section 94A was added to the British North America Act, 1867 to allow the Canadian parliament to provide for pensions.[na 4] This was extended in 1964 to allow supplementary benefits, including disability and survivors' benefits.[na 5] The era saw an increase in First Ministers' Conferences to resolve federal-provincial issues. The Supreme Court of Canada became the court of final appeal after the 1949 abolition of appeals to the Judicial Committee of the Privy Council and parliament received the power to amend the constitution, limited to non-provincial matters and subject to other constraints.[na 6]
1961 saw the last instance of a lieutenant governor reserving a bill passed by a provincial legislature. Frank Lindsay Bastedo, Lieutenant Governor of Saskatchewan, withheld Royal Assent and reserved Bill 5, An Act to Provide for the Alteration of Certain Mineral Contracts, to the Governor-in-Council for review. According to Bastedo, "[T]his is a very important bill affecting hundreds of mineral contracts. It raises implications which throw grave doubts of the legislation being in the public interest. There is grave doubt as to its validity". The act was upheld in an Order in Council by the federal government.[na 7]
Although Canada achieved full status as a sovereign nation in the Statute of Westminster 1931, there was no consensus about how to amend the constitution; attempts such as the 1965 Fulton–Favreau formula and the 1971 Victoria Charter failed to receive unanimous approval from both levels of government. When negotiations with the provinces again stalled in 1982, Trudeau threatened to take the case for patriation to the British parliament "[without] bothering to ask one premier". According to the federal cabinet and Crown counsel, if the British Crown (in council, parliament and on the bench) exercised sovereignty over Canada, it would do so only at the request of the federal ministers.
Manitoba, Newfoundland and Quebec posed reference questions to their respective courts of appeal, in which five other provinces intervened in support. In his ruling, Justice Joseph O'Sullivan of the Manitoba Court of Appeal held that the federal government's position was incorrect; the constitutionally-entrenched principle of responsible government meant that "Canada had not one responsible government but eleven." Officials in the United Kingdom indicated that the British parliament was under no obligation to fulfill a request for legal changes desired by Trudeau, particularly if Canadian convention was not followed. All rulings were appealed to the Supreme Court of Canada. In a decision later known as the Patriation Reference, the court ruled that such a convention existed but did not prevent the federal parliament from attempting to amend the constitution without provincial consent and it was not the role of the courts to enforce constitutional conventions.
The Canadian parliament asked the British parliament to approve the Constitution Act, 1982, which it did in passage of the Canada Act 1982. This resulted in the introduction of the Canadian Charter of Rights and Freedoms, the transfer of constitutional amendment to a Canadian framework and the addition of section 92A to the Constitution Act, 1867, giving the provinces more jurisdiction over their natural resources.
As a federal monarchy, the Canadian Crown is present in all jurisdictions in the country,[nb 18] with the headship of state a part of all equally. Sovereignty is conveyed not by the governor general or federal parliament, but through the Crown itself as a part of the executive, legislative and judicial branches of Canada's 11 (one federal and 10 provincial) legal jurisdictions; linking the governments into a federal state, the Crown is "divided" into 11 "crowns". The fathers of the Canadian Confederation viewed the constitutional monarchy as a bulwark against potential fracturing of the Canadian federation, and the Crown remains central to Canadian federalism.
The federal-provincial distribution of legislative powers (also known as the division of powers) defines the scope of the federal and provincial legislatures. These have been identified as exclusive to the federal or provincial jurisdictions or shared by all. Section 91 of the Constitution Act, 1867, lists the major federal parliament powers, based on the concepts of peace, order, and good government; while Section 92 of the Constitution Act, 1867 enumerates those of the provincial governments.
The act puts remedial legislation on education rights, uniform laws relating to property and civil rights (in all provinces other than Quebec), creation of a general court of appeal and other courts "for the better Administration of the Laws of Canada," and implementing obligations arising from foreign treaties, all under the purview of the federal legislature in Section 91. Some aspects of the Supreme Court of Canada were elevated to constitutional status in 1982.[nb 19]
The act lists the powers of the provincial parliaments (subject to the federal parliament's authority to regulate inter-provincial movement) in Section 92. These powers include the exploration, development and export to other provinces of non-renewable natural resources, forestry resources and electrical energy. Education is under provincial jurisdiction, subject to the rights of separate schools.
Old-age pensions, agriculture and immigration are shared within federal and provincial jurisdictions. One prevails over the other, however: for pensions, federal legislation will not displace provincial laws, and for agriculture and immigration it is the reverse.[why?]
Jurisdiction over Crown property is divided between the provincial legislatures and the federal parliament, with the key provisions Sections 108, 109, and 117 of the Constitution Act, 1867. Public works are the property of the federal Crown, and natural resources are within the purview of the provinces.[nb 20] Title to such property is not vested in one jurisdiction or another, however, since the Canadian Crown is indivisible. Section 109 has been given a particularly-broad meaning; provincial legislation regulating labour used to harvest and the disposal of natural resources does not interfere with federal trade and commerce power,[nb 21][nb 22] and royalties have been held to cover the law relating to escheats.[nb 23] Canada cannot unilaterally create Indian reserves, since the transfer of such lands requires federal and provincial approval by Order in Council (although discussion exists about whether this is sound jurisprudence).[nb 24]
The provincial power to manage Crown land did not initially extend to Manitoba, Alberta and Saskatchewan when they were created from part of the Northwest Territories, since the land was vested in the federal Crown. It was vacated on some land (the Railway Belt and the Peace River Block) by British Columbia when it entered the confederation. Title to this land was not vested in those provinces until the passage of the Natural Resources Acts in 1930. The power is not absolute, however; provincial Crown land may be regulated or expropriated for federal purposes.[nb 25][nb 26] The administration of crown land is also subject to the rights of First Nations[nb 27] (since they are a relevant interest),[nb 28] and provincial power "is burdened by the Crown obligations toward the Aboriginal people in question".[nb 29] Debate exists about whether such burdens apply in the same manner in the Western provinces under the Natural Resources Acts.
Taxation is a power of the federal and provincial legislatures; provincial taxation is more restricted, in accordance with sections 92(2) and 92(9) of the Constitution Act, 1867. In Allard Contractors Ltd. v. Coquitlam (District), provincial legislatures may levy an indirect fee as part of a valid regulatory scheme.[nb 33]Gérard La Forest observed obiter dicta that section 92(9) (with provincial powers over property and civil rights and matters of a local or private nature) allows for the levying of license fees even if they constitute indirect taxation.
Parliament has the power to spend money on public debt and property. Although the Supreme Court of Canada has not ruled directly about constitutional limits on federal spending power,[nb 34] parliament can transfer payments to the provinces.[c] This arises from the 1937 decision of the Judicial Committee of the Privy Council on the Unemployment Insurance Reference, where Lord Atkin observed: "Assuming the Dominion has collected by means of taxation a fund, it by no means follows that any legislation which disposes of it is necessarily within Dominion competence ... If on the true view of the legislation it is found that in reality in pith and substance the legislation invades civil rights within the Province, or in respect of other classes of subjects otherwise encroaches upon the provincial field, the legislation will be invalid".[nb 36] In Re Canada Assistance Plan, Justice Sopinka held that the withholding of federal money previously granted to fund a matter within provincial jurisdiction does not amount to the regulation of that matter.[nb 37]
Federal legislative power
Much distribution of power has been ambiguous, leading to disputes which have been decided by the Judicial Committee of the Privy Council and (after 1949) the Supreme Court of Canada. The nature of the Canadian constitution was described by the Privy Council in 1913 as not truly federal (unlike the United States and Australia); although the British North America Act, 1867, states in its preamble that the colonies had expressed "their desire to be federally united into one Dominion", "the natural and literal interpretation of the word [federal] confines its application to cases in which these States, while agreeing on a measure of delegation, yet in the main continue to preserve their original Constitutions". The Privy Council determined that the Fathers of Confederation desired a "general Government charged with matters of common interest, and new and merely local Governments for the Provinces". Matters other than those listed in the British North America Act, 1867, as the responsibility of the federal or provincial parliaments fell to the federal legislature (the reverse of the arrangement between the federal and state congresses in the United States).[nb 38]
National and provincial concerns
The preamble of Section 91 of the Constitution Act, 1867 states: "It shall be lawful for the Queen ... 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". In addition to assigning powers not stated elsewhere (which has been narrowly interpreted), this has led to the creation of the national-emergency and national-concern doctrines.
The federal government is partially limited by powers assigned to the provincial legislatures; for example, the Canadian constitution created broad provincial jurisdiction over direct taxation and property and civil rights. Many disputes between the two levels of government revolve around conflicting interpretations of the meaning of these powers.
By 1896, the Judicial Committee of the Privy Council arrived at a method of interpretation, known as the "four-departments doctrine", in which jurisdiction over a matter is determined in the following order:
Does it fall under Section 92, ss. 1–15?
Can it be characterized as falling under Section 91, ss. 1–29?
Is it of a general nature, bringing it within Section 91's residuary clause
Although the Statute of Westminster 1931 declared that the Parliament of Canada had extraterritorial jurisdiction, the provincial legislatures did not achieve similar status. According to s. 92, "In each Province the Legislature may exclusively make Laws ...".
If a provincial law affects the rights of individuals outside the province:
If it is, in pith and substance, provincial, ancillary effects on the rights of individuals outside the province are irrelevant[nb 42] but
Where it is, in pith and substance, legislation in relation to the rights of individuals outside the province, it will be ultra vires the province[nb 5][nb 43]
In The Queen (Man.) v. Air Canada, it was held that the s. 92(2) power providing for "direct taxation within the province" does not extend to taxing sales on flights passing over (or through) a province, but the question of how far provincial jurisdiction can extend into a province's airspace was left undecided.[nb 44] However, the property and civil rights power does allow for determining rules with respect to conflict of laws in civil matters.[na 10]
Federal jurisdiction arises in several circumstances:
Under the national-emergency doctrine for temporary legislation (the War Measures Act)
Under the national-concern doctrine for:
Matters not existing at confederation (radio and television)
The gap approach, employed sparingly, identifies areas of jurisdiction arising from oversights by the drafters of the constitution; for example, federal jurisdiction to incorporate companies is inferred from the power provinces have under Section 92 for "The Incorporation of Companies with Provincial Objects".
Uniformity of federal law
Section 129 of the Constitution Act, 1867 provided for laws in effect at the time of Confederation to continue until repealed or altered by the appropriate legislative authority. Similar provisions were included in the terms of union of other territories that were subsequently incorporated into Canada.
The uniformity of laws in some areas of federal jurisdiction was significantly delayed. Offences under the Criminal Code were not made uniform until 1892, when common-law criminal offences were abolished.Divorce law was not made uniform until 1968, Canadian maritime law not until 1971 and marriage law not until 2005. Provisions of the Civil Code of Lower Canada, adopted in 1865 by the former Province of Canada, affecting federal jurisdiction continued to be in force in Quebec (if they had not been displaced by other federal Acts) until their repeal on 15 December 2004.[na 11]
According to the Supreme Court of Canada, "our Constitution is based on an allocation of exclusive powers to both levels of government, not concurrent powers, although these powers are bound to interact in the realities of the life of our Constitution."[nb 45]Chief Justice Dickson observed the complexity of that interaction:
The history of Canadian constitutional law has been to allow for a fair amount of interplay and indeed overlap between federal and provincial powers. It is true that doctrines like interjurisdictional and Crown immunity and concepts like "watertight compartments" qualify the extent of that interplay. But it must be recognized that these doctrines and concepts have not been the dominant tide of constitutional doctrines; rather they have been an undertow against the strong pull of pith and substance, the aspect doctrine and, in recent years, a very restrained approach to concurrency and paramountcy issues.[nb 46]
Although the federal power to regulate fisheries does not override provincial authority to require a permit for catching fish in waters under provincial control,[nb 48] the regulation of recreational fisheries has been partially delegated under the Fisheries Act[na 12] to the provinces for specified species in specific provinces.[na 13]
Laws arising from the property and civil-rights power will be used to complement the interpretation of federal legislation where the federal Act has not provided otherwise, but federal power cannot be used to create rules of private law in areas outside its jurisdiction.[nb 52][na 14]
In 1899, Lord Watson asserted during the argument in CPR v Bonsecours[nb 54] that neither the federal parliament nor the provincial legislatures could give legislative authority to the other level. Subsequent attempts to dovetail federal and provincial legislation to achieve certain ends met with difficulty, such as an attempt by Saskatchewan to ensure enforcement of a federal statute[na 15] by enacting a complementary Act[na 16] declaring that the federal Act would continue in force under provincial authority if it was ruled ultra vires. The Saskatchewan Court of Appeal ruled a federal and provincial Act ultra vires, voiding both as an attempt by the province to vest powers in parliament unauthorized by the BNA Act.[nb 55]
The matter was addressed in 1950 by the Supreme Court, which held ultra vires a proposed Nova Scotia Act which would have authorized the inter-delegation of legislative and taxation authority between Parliament and the Nova Scotia legislature.[nb 56] In that decision, Justice Rand explained the distinction between delegation to a subordinate body and that to a legislative body.[h]
Later attempts to achieve federal-provincial coordination have succeeded with other types of legislative schemes involving:
Conditional legislation (such as a federal Act, providing that it will not apply where a provincial Act has been enacted in a given matter). As Justice Rand declared in 1959, "That Parliament can so limit the operation of its own legislation and that it may do so upon any such event or condition is not open to serious debate".[nb 57]
Incorporation by reference or adoption (for example, a federal regulation prohibiting vehicles from operating on a federal highway except "in accordance with the laws of the province and the municipality in which the highway is situated")[na 17]
Joint schemes with administrative cooperation, such as the administrative authority granted by federal law to provincial transport boards to license extraprovincial transport[na 18]
Although an international agreement governing broadcasting was not a treaty of the British Empire, the Radio Reference held that it fell within federal jurisdiction; Canada's obligations under its agreements in this field required it to pass legislation applying to all Canadian residents, and the matter could be seen as analogous to telegraphs (already in the federal sphere).
The Labour Conventions Reference dealt with labour relations (clearly within provincial jurisdiction); since the conventions were not treaties of the British Empire and no plausible argument could be made for the field attaining a national dimension or becoming of national concern, the Canadian Parliament was unable to exercise new legislative authority.
It must not be thought that the result of this decision is that Canada is incompetent to legislate in performance of treaty obligations. In totality of legislative powers, Dominion and Provincial together, she is fully equipped. But the legislative powers remain distributed and if in the exercise of her new functions derived from her new international status she incurs obligations they must, so far as legislation be concerned when they deal with provincial classes of subjects, be dealt with by the totality of powers, in other words by co-operation between the Dominion and the Provinces. While the ship of state now sails on larger ventures and into foreign waters she still retains the watertight compartments which are an essential part of her original structure.
This case left undecided the extent of federal power to negotiate, sign and ratify treaties dealing with areas under provincial jurisdiction, and has generated extensive debate about complications introduced in implementing Canada's subsequent international obligations; the Supreme Court of Canada has indicated in several dicta that it might revisit the issue in an appropriate case.
S. 96 has been construed to hold that neither the provincial legislatures nor Parliament can enact legislation removing part of the inherent jurisdiction of the superior courts.[nb 59]
S. 121 states, "All Articles of the Growth, Produce, or Manufacture of any one of the Provinces shall, from and after the Union, be admitted free into each of the other Provinces". This amounts to a prohibition of inter-provincial tariffs.
S. 125 states, "No Lands or Property belonging to Canada or any Province shall be liable to Taxation".
Under s. 129, limits have been placed on the ability of the legislatures of Ontario and Quebec to amend or repeal Acts of the former Province of Canada. Where such an act created a body corporate operating in the former Province, the Judicial Committee of the Privy Council held that such bodies cannot have "provincial objects" and only the Parliament of Canada had power to deal with such acts.[nb 60] It has been held that this restriction exists for any Act applying equally to Upper and Lower Canada,[i] which became problematic when the Civil Code of Lower Canada was replaced by the Civil Code of Quebec.
While the Parliament of Canada has the ability to bind the Crown in right of Canada or of any province, the converse is not true for the provincial legislatures, as "[p]rovincial legislation cannot proprio vigore [ie, of its own force] take away or abridge any privilege of the Crown in right of the Dominion."[nb 62]
^The Alberta Court of Appeal in Winterhaven Stables Limited v. Canada (Attorney General) characterized that as possessing the following nature: "[The federal parliament] is entitled to spend the money that it raises through proper exercise of its taxing power in the manner that it chooses to authorize. It can impose conditions on such disposition so long as the conditions do not amount in fact to a regulation or control of a matter outside federal authority. The federal contributions are now made in such a way that they do not control or regulate provincial use of them. As well there are opting out arrangements that are available to those provinces who choose not to participate in certain shared-cost programs.[nb 35]
"But if one looks at the practical effects of the exercise of the emergency power, one must conclude that it operates so as to give to Parliament for all purposes necessary to deal with the emergency, concurrent and paramount jurisdiction over matters which would normally fall within exclusive provincial jurisdiction. To that extent, the exercise of that power amounts to a temporary pro tanto amendment of a federal Constitution by the unilateral action of Parliament. The legitimacy of that power is derived from the Constitution: when the security and the continuation of the Constitution and of the nation are at stake, the kind of power commensurate with the situation 'is only to be found in that part of the Constitution which establishes power in the State as a whole'."[nb 40]
^"The extraordinary nature and the constitutional features of the emergency power of Parliament dictate the manner and form in which it should be invoked and exercised. It should not be an ordinary manner and form. At the very least, it cannot be a manner and form which admits of the slightest degree of ambiguity to be resolved by interpretation. In cases where the existence of an emergency may be a matter of controversy, it is imperative that Parliament should not have recourse to its emergency power except in the most explicit terms indicating that it is acting on the basis of that power. Parliament cannot enter the normally forbidden area of provincial jurisdiction unless it gives an unmistakable signal that it is acting pursuant to its extraordinary power. Such a signal is not conclusive to support the legitimacy of the action of Parliament but its absence is fatal."
The national concern doctrine is separate and distinct from the national emergency doctrine of the peace, order and good government power, which is chiefly distinguishable by the fact that it provides a constitutional basis for what is necessarily legislation of a temporary nature;
The national concern doctrine applies to both new matters which did not exist at Confederation and to matters which, although originally matters of a local or private nature in a province, have since, in the absence of national emergency, become matters of national concern;
For a matter to qualify as a matter of national concern in either sense it must have a singleness, distinctiveness and indivisibility that clearly distinguishes it from matters of provincial concern and a scale of impact on provincial jurisdiction that is reconcilable with the fundamental distribution of legislative power under the Constitution;
In determining whether a matter has attained the required degree of singleness, distinctiveness and indivisibility that clearly distinguishes it from matters of provincial concern it is relevant to consider what would be the effect on extra‑provincial interests of a provincial failure to deal effectively with the control or regulation of the intra‑provincial aspects of the matter.
^Aeronautics Reference at p. 8: # The legislation of the Parliament of the Dominion, so long as it strictly relates to subjects of legislation expressly enumerated in section 91, is of paramount authority, even if it trenches upon matters assigned to the Provincial Legislature by section 92.
The general power of legislation conferred up on the Parliament of the Dominion by section 91 of the Act in supplement of the power to legislate upon the subjects expressly enumerated must be strictly confined to such matters as are unquestionably of national interest and importance, and must not trench on any of the subjects enumerated in section 92, as within the scope of Provincial legislation, unless these matters have attained such dimensions as to affect the body politic of the Dominion.
It is within the competence of the Dominion Parliament to provide for matters which though otherwise within the legislative competence of the Provincial Legislature, are necessarily incidental to effective legislation by the Parliament of the Dominion upon a subject of legislation expressly enumerated in section 91.
There can be a domain in which Provincial and Dominion legislation may overlap, in which case, neither legislation will be ultra vires if the field is clear, but if the field is not clear and the two legislations meet, the Dominion legislation must prevail.
"In the generality of actual delegation to its own agencies, Parliament, recognizing the need of the legislation, lays down the broad scheme and indicates the principles, purposes and scope of the subsidiary details to be supplied by the delegate: under the mode of enactment now being considered, the real and substantial analysis and weighing of the political considerations which would decide the actual provisions adopted, would be given by persons chosen to represent local interests.
Since neither is a creature nor a subordinate body of the other, the question is not only or chiefly whether one can delegate, but whether the other can accept. Delegation implies subordination and in Hodge v. The Queen, the following observations ... appear:
Within these limits of subjects and area the local legislature is supreme, and has the same authority as the Imperial Parliament, or the parliament of the Dominion, would have had under like circumstances to confide to a municipal institution or body of its own creation authority to make by-laws or resolutions as to subjects specified in the enactment, and with the object of carrying the enactment into operation and effect....
It was argued at the bar that a legislature committing important regulations to agents or delegates effaces itself. That is not so. It retains its powers intact, and can, whenever it pleases, destroy the agency it has created and set up another, or take the matter directly into his own hands. How far it shall seek the aid of subordinate agencies, and how long it shall continue them, are matters for each legislature, and not for Courts of Law, to decide."
^Ex parte O'Neill, RJQ 24 SC 304, where it was held that the Legislative Assembly of Quebec was unable to repeal the Temperance Act, 1864,[na 19] but it could pass a concurrent statute for regulating liquor traffic within the Province. However, it has also been held that the Parliament of Canada could not repeal that Act with respect only to Ontario.[nb 61]
