NCA Constitutional Law Exam — November 2026 Sitting Guide

The short answer: NCA Constitutional Law covers the division of powers between federal and provincial governments, the Canadian Charter of Rights and Freedoms, constitutional interpretation, and judicial review. It is the most conceptually demanding NCA subject, requiring you to master both the structure of the constitution and a large body of SCC jurisprudence. Allow 10–14 weeks for focused preparation.

What the NCA Constitutional Law Exam Covers

The exam has two major components:

Part 1: Division of Powers

• Characterization of legislation: Pith and substance analysis, dominant purpose
• Federal heads of power: s.91 — POGG, criminal law, trade and commerce, banking, taxation
• Provincial heads of power: s.92 — property and civil rights, matters of a merely local nature
• Doctrines: Double aspect, paramountcy, interjurisdictional immunity, cooperative federalism
• Ancillary powers: Necessarily incidental doctrine

Division of Powers — Deep Dive

The division of powers is the structural backbone of Canadian constitutional law. The Constitution Act, 1867 divides legislative authority between Parliament (s.91) and the provincial legislatures (s.92). On the NCA exam, you will be expected to classify legislation under the correct head of power and resolve conflicts between overlapping federal and provincial jurisdiction.

Sections 91 and 92 of the Constitution Act, 1867

Section 91 grants Parliament the power to legislate for “Peace, Order, and good Government of Canada” (POGG) in relation to all matters not exclusively assigned to the provinces. The enumerated federal heads of power include trade and commerce (s.91(2)), criminal law (s.91(27)), banking (s.91(15)), and taxation (s.91(3)).

POGG operates in three branches: the gap branch (residual matters not assigned to either level), the national concern branch (R v Crown Zellerbach, [1988] 1 SCR 401), and the emergency branch (temporary federal jurisdiction during national crises, as in the Anti-Inflation Reference, [1976] 2 SCR 373).

Trade and commerce has two branches: interprovincial/international trade (relatively uncontroversial) and general trade affecting the whole dominion (General Motors of Canada v City National Leasing, [1989] 1 SCR 641). The second branch requires a five-part test.

Criminal law power (s.91(27)) is broad. Legislation qualifies as criminal law if it has a valid criminal law purpose (public peace, order, security, health, morality), is backed by a prohibition, and carries a penalty (Reference re Firearms Act, 2000 SCC 31). The NCA exam frequently tests the boundary between criminal law and provincial regulation of property and civil rights.

Section 92 grants provinces exclusive jurisdiction over property and civil rights (s.92(13)), matters of a merely local or private nature (s.92(16)), administration of justice (s.92(14)), and municipal institutions (s.92(8)). Section 92(13) is the broadest provincial head of power and encompasses contract, tort, property, and most commercial regulation within the province.

Part 2: Canadian Charter of Rights and Freedoms

• Application: Government action (s.32), private actors
• Substantive rights: s.2 (fundamental freedoms), s.7 (life, liberty, security), s.15 (equality)
• Section 1 Oakes test: Pressing objective, proportionality (rational connection, minimal impairment, proportionality of effects)
• Section 33: Notwithstanding clause
• Remedies: s.24 individual remedies, s.52 declarations of invalidity

Charter Analysis — In Depth

The Canadian Charter of Rights and Freedoms, entrenched in Part I of the Constitution Act, 1982, is the most heavily tested area on the NCA Constitutional Law exam. Charter analysis follows a structured framework: (1) Does the Charter apply? (2) Has a right been infringed? (3) Can the infringement be justified under s.1? (4) What is the appropriate remedy?

Section 1 — The Oakes Test

Section 1 of the Charter states that rights are subject “only to such reasonable limits prescribed by law as can be demonstrably justified in a free and democratic society.” The test for justification was set out in R v Oakes, [1986] 1 SCR 103, and has two main stages:

1. Pressing and substantial objective: The government must demonstrate that the objective of the limiting measure is pressing and substantial enough to warrant overriding a constitutionally protected right.
2. Proportionality: The means chosen must be proportional, assessed through three sub-tests:
   • Rational connection: The limit must be rationally connected to the government’s objective.
   • Minimal impairment: The limit must impair the right as little as reasonably possible. Courts grant some deference here, especially where the government is mediating between competing groups.
   • Proportionality of effects: The salutary effects of the measure must outweigh its deleterious effects on the right.

Section 2 — Fundamental Freedoms

Section 2 protects freedom of conscience and religion (s.2(a)), freedom of expression (s.2(b)), freedom of peaceful assembly (s.2(c)), and freedom of association (s.2(d)). Freedom of expression under s.2(b) has an extremely broad scope — it covers any activity that conveys meaning, subject only to violence (Irwin Toy v Quebec, [1989] 1 SCR 927). Most s.2(b) cases are ultimately decided at the s.1 stage because the right is so broad.

Section 7 — Life, Liberty, and Security of the Person

Section 7 guarantees that everyone has the right to life, liberty, and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice. The analysis proceeds in two steps: (1) Has the claimant’s right to life, liberty, or security of the person been engaged? (2) If so, is the deprivation in accordance with the principles of fundamental justice? Key principles of fundamental justice include the prohibition against arbitrariness, overbreadth, and gross disproportionality (Canada (AG) v Bedford, 2013 SCC 72). The landmark case Carter v Canada (AG), 2015 SCC 5, applied s.7 to strike down the criminal prohibition on physician-assisted dying.

Section 15 — Equality Rights

Section 15 guarantees equality before and under the law and equal protection and benefit of the law without discrimination based on enumerated or analogous grounds. The test from Andrews v Law Society of BC, [1989] 1 SCR 143, as refined in later cases, asks: (1) Does the law create a distinction based on an enumerated or analogous ground? (2) Does the distinction create a disadvantage by perpetuating prejudice or stereotyping? Substantive equality, not merely formal equality, is the standard.

Section 33 — The Notwithstanding Clause

Section 33 allows Parliament or a provincial legislature to declare that an Act or a provision thereof shall operate notwithstanding ss.2 or 7–15 of the Charter. The declaration must be expressly stated, is renewable every five years, and does not apply to democratic rights (ss.3–5), mobility rights (s.6), or language rights (ss.16–23). The notwithstanding clause reflects the compromise between parliamentary sovereignty and entrenched rights. Quebec has used s.33 more frequently than any other province, most notably in Bill 21 (the “laicity” law).

• Canadian Western Bank v Alberta, 2007 SCC 22 — interjurisdictional immunity restrained
• Quebec (AG) v Lacombe, 2010 SCC 38 — double aspect and paramountcy
• R v Oakes, [1986] 1 SCR 103 — the Oakes test for s.1 justification
• R v Big M Drug Mart, [1985] 1 SCR 295 — s.2(a) freedom of religion
• Irwin Toy v Quebec, [1989] 1 SCR 927 — s.2(b) freedom of expression
• Andrews v Law Society of BC, [1989] 1 SCR 143 — s.15 equality rights
• Carter v Canada (AG), 2015 SCC 5 — s.7 and physician-assisted dying
• Reference re Secession of Quebec, [1998] 2 SCR 217 — constitutional principles
• Edwards v AG Canada, [1930] AC 124 (Persons Case) — living tree doctrine

Federalism Doctrines

The NCA exam expects you to apply several doctrines that mediate the overlap between federal and provincial jurisdiction. These doctrines are not abstract — they determine whether legislation is valid and operative.

Pith and Substance

Every division of powers question begins with characterization. The court asks: what is the “pith and substance” — the dominant purpose and legal effect — of the impugned legislation? If the pith and substance falls within a head of power assigned to the enacting legislature, the law is valid, even if it incidentally affects matters within the other level’s jurisdiction. This is the single most important analytical step in any division of powers problem.

Double Aspect Doctrine

Some subject matters have both a federal and a provincial aspect. The double aspect doctrine allows both levels of government to legislate on the same subject matter, provided each law can be characterized under a valid head of power. For example, dangerous driving can be addressed by Parliament under criminal law and by provinces under highway traffic regulation.

Federal Paramountcy

Where valid federal and provincial laws conflict, the federal law prevails and the provincial law is rendered inoperative to the extent of the inconsistency. Conflict arises in two situations: (1) operational conflict (it is impossible to comply with both laws simultaneously), and (2) frustration of federal purpose (the provincial law frustrates the purpose of the federal law). See Quebec (AG) v Canadian Owners and Pilots Association, 2010 SCC 39.

Interjurisdictional Immunity

This doctrine protects the “core” of exclusive federal (or provincial) powers from being impaired by legislation enacted by the other level. The SCC in Canadian Western Bank v Alberta, 2007 SCC 22, significantly restrained this doctrine, holding that it should be applied with restraint and only where supported by existing precedent. On the NCA exam, be prepared to argue both for and against the application of interjurisdictional immunity.

Ancillary Powers (Necessarily Incidental Doctrine)

Where a provision of a statute falls outside the enacting legislature’s jurisdiction, it may still be saved if it is necessarily incidental to a valid legislative scheme. The test from General Motors v City National Leasing asks how well the impugned provision is integrated into the larger scheme. The more serious the encroachment on the other level’s jurisdiction, the tighter the required integration.

Aboriginal and Treaty Rights — Section 35

Section 35 of the Constitution Act, 1982 recognizes and affirms the existing Aboriginal and treaty rights of the Aboriginal peoples of Canada. Although s.35 sits outside the Charter (in Part II of the Constitution Act, 1982), it is constitutionally entrenched and is tested on the NCA exam.

The test for establishing an Aboriginal right was set out in R v Van der Peet, [1996] 2 SCR 507: the claimant must demonstrate that the practice, custom, or tradition was integral to the distinctive culture of the Aboriginal group prior to European contact. Aboriginal title, a subset of Aboriginal rights, was comprehensively addressed in Tsilhqot’in Nation v British Columbia, 2014 SCC 44.

Duty to consult: The Crown has a constitutional duty to consult and, where appropriate, accommodate Aboriginal peoples when contemplating conduct that might adversely impact established or potential Aboriginal or treaty rights (Haida Nation v British Columbia, 2004 SCC 73). The scope of the duty ranges from notice and discussion (where the claim is weak and the impact minor) to deep consultation and accommodation (where the claim is strong and the impact significant).

Section 35 rights are not absolute — the government may infringe them if the infringement is justified under the test from R v Sparrow, [1990] 1 SCR 1075: the objective must be compelling and substantial, and the infringement must be consistent with the Crown’s fiduciary obligation to Aboriginal peoples.

Condensed 4-Week Study Plan

If you are starting late or studying Constitutional Law alongside other NCA subjects, here is a condensed 4-week plan that covers the essential material:

1. Week 1 — Division of Powers Framework: Read the constitutional text (ss.91–92, Constitution Act, 1867). Master pith and substance analysis. Study POGG (gap, national concern, emergency branches). Work through the criminal law power and trade and commerce. Key cases: Reference re Firearms Act, General Motors v City National Leasing, R v Crown Zellerbach.
2. Week 2 — Federalism Doctrines and Aboriginal Rights: Study paramountcy, double aspect, interjurisdictional immunity, and ancillary powers. Cover s.35 Aboriginal and treaty rights, the duty to consult, and the Van der Peet test. Key cases: Canadian Western Bank, Haida Nation, Tsilhqot’in Nation.
3. Week 3 — Charter Analysis: Master the analytical framework: application (s.32), substantive rights (ss.2, 7, 15), and the Oakes test (s.1). Study s.33 notwithstanding clause and remedies (ss.24, 52). Key cases: R v Oakes, Irwin Toy, Carter, Andrews, Bedford.
4. Week 4 — Practice and Review: Write at least two full practice exams under timed conditions. Focus on structuring your answers — always follow the analytical framework step by step. Review your weakest areas. Consolidate case holdings into one-line summaries for quick reference.

Why Constitutional Law Is Difficult — and How to Approach It

Constitutional Law is difficult because it requires holding two large frameworks in your head simultaneously — the division of powers and the Charter — and applying them with precision to novel fact scenarios. The key insight: structure is everything.

For division of powers problems: always start with characterization (pith and substance), then identify the applicable head of power, then address any overlap doctrines. For Charter problems: always start with application (government action?), then identify the right, then apply Oakes if the right is infringed. Never skip steps in the analysis framework — you lose marks for missing the structure even if your substantive analysis is correct.
