Why Supreme Court of Canada cases matter
The Supreme Court of Canada is Canada's final court of appeal and has jurisdiction over disputes in every area of law. It was established in 1875, but it did not become Canada's final court of appeal until appeals to the Judicial Committee of the Privy Council were abolished in 1949. The Court now plays a central role in interpreting the Constitution, the Canadian Charter of Rights and Freedoms, federalism, criminal law, administrative law, Indigenous rights and other areas of Canadian law. A landmark case does not always create a simple rule that applies identically to every later dispute. Supreme Court judgments establish legal tests, interpret constitutional language, distinguish earlier decisions and often qualify their holdings according to facts and context. The summaries on this page therefore describe each precedent's principal legal contribution rather than suggesting that a case automatically decides every later dispute involving the same topic.
1. Charter Section 1 — R. v. Oakes (1986)
R. v. Oakes is the leading authority on Section 1 of the Canadian Charter. The Court developed the proportionality framework used when the government seeks to justify a limit on a Charter right as a reasonable limit prescribed by law and demonstrably justified in a free and democratic society. The analysis first asks whether the legislative objective is sufficiently important. It then considers whether the means are rationally connected to the objective, whether the measure impairs the right as little as reasonably possible in the circumstances, and whether the law's beneficial and deleterious effects are proportionate overall. Later Supreme Court cases have refined and adapted the proportionality analysis to different constitutional contexts.
2. Refugee and Immigration Rights — Singh v. Minister of Employment and Immigration (1985)
Singh is a foundational immigration and Charter decision. The case concerned refugee claimants challenging procedures used to determine refugee status. The Supreme Court held that people physically present in Canada can benefit from Section 7 and that the refugee determination procedures in issue did not satisfy the principles of fundamental justice because they did not provide adequate procedural safeguards, including an oral hearing in circumstances where credibility and related issues were at stake. The decision is especially important because it rejected the idea that constitutional procedural protections under Section 7 belong only to Canadian citizens. It helped establish that immigration and refugee decision-making is subject to constitutional scrutiny.
3. Charter Privacy — Hunter v. Southam Inc. (1984)
Hunter v. Southam is a foundational Section 8 privacy decision. The Court held that the right to be secure against unreasonable search or seizure requires prior authorization by a neutral and impartial decision-maker in circumstances where the law requires a warrant. The case helped establish the modern Canadian constitutional approach to reasonable expectations of privacy and search authorization.
4. Abortion and Section 7 — R. v. Morgentaler (1988)
R. v. Morgentaler concerned the Criminal Code scheme regulating access to abortion through therapeutic abortion committees. The Supreme Court held the impugned provision unconstitutional under Section 7. The judgments differed in reasoning, but the decision is a landmark authority concerning liberty, security of the person and fundamental justice. It is more accurate to say that Morgentaler struck down the particular criminal-law scheme than to describe the case as simply establishing an unlimited constitutional 'right to abortion.' Later Canadian law on abortion has developed in a different statutory and constitutional environment.
5. Section 15 Equality — Andrews v. Law Society of British Columbia (1989)
Andrews was the first major Supreme Court of Canada interpretation of Section 15 of the Charter. The Court rejected a purely formal approach that would treat identical treatment as sufficient for equality. The decision established a substantive-equality framework and recognized the importance of discrimination based on enumerated or analogous grounds. The modern Section 15 test has subsequently evolved, particularly through cases such as Law v. Canada, R. v. Kapp and Fraser v. Canada.
6. Same-Sex Equality — M. v. H. (1999)
M. v. H. held that Ontario's exclusion of same-sex partners from the statutory definition governing spousal support violated Section 15 and was not justified under Section 1. The case was an important equality precedent concerning sexual orientation and the legal recognition of same-sex relationships.
7. Evidence and Charter Remedies — R. v. Grant (2009)
R. v. Grant established the modern framework for Section 24(2) of the Charter when evidence is obtained in a manner that infringes or denies a Charter right. Courts consider three lines of inquiry: the seriousness of the Charter-infringing state conduct, the impact of the breach on the accused's Charter-protected interests, and society's interest in adjudicating the case on its merits. The ultimate question is whether admission of the evidence, considering all the circumstances, would bring the administration of justice into disrepute. The framework is not confined to Section 8 searches; it applies to evidence obtained through Charter violations generally.
8. Criminal Trial Delay — R. v. Jordan (2016)
R. v. Jordan transformed Section 11(b) delay analysis by introducing presumptive ceilings on the amount of time between a criminal charge and the actual or anticipated end of trial. The ceilings are 18 months for cases tried in provincial court and 30 months for cases tried in superior court, subject to deductions for defence delay and the exceptional-circumstances framework. A delay exceeding the applicable ceiling is presumptively unreasonable, not automatically unconstitutional in every imaginable circumstance. The framework also recognizes that below-ceiling cases can still raise unreasonable-delay issues in exceptional situations under later Supreme Court guidance.
9. Thermal Imaging and Privacy — R. v. Tessling (2004)
R. v. Tessling concerned police use of Forward Looking Infra-Red technology to measure heat emanating from a residence. The Supreme Court concluded on the evidence that the information obtained did not reveal an intimate biographical core or a sufficiently reasonable expectation of privacy to amount to a search under Section 8. The case is an important privacy precedent because it examines how constitutional search-and-seizure principles apply to technology capable of obtaining information about a private home without physical entry. It should not be summarized merely as a general 'digital surveillance' case.
10. Freedom of Association and Collective Bargaining — Health Services (2007)
Health Services recognized that Section 2(d) freedom of association protects a meaningful process of collective bargaining. The Court held that legislation substantially interfering with that protected process could violate the Charter and would then require justification under Section 1. The case does not constitutionalize every provision of a collective agreement. The protected interest concerns the ability of employees, through their associations, to pursue workplace goals through a meaningful collective-bargaining process.
11. Constitutional Right to Strike — Saskatchewan Federation of Labour (2015)
Saskatchewan Federation of Labour held that the ability of workers to strike is an essential component of meaningful collective bargaining protected by Section 2(d). The Court therefore found that Saskatchewan's public-sector essential-services legislation violated Section 2(d) because it prohibited strikes for a significant class of employees without providing an adequate alternative mechanism for resolving bargaining disputes. The decision does not mean every statutory restriction on strikes is unconstitutional. Governments can pursue legitimate public-safety and essential-service objectives, but significant restrictions must satisfy the Charter framework and, where necessary, Section 1.
12. Indigenous Rights and the Duty to Consult — Haida Nation (2004)
Haida Nation established the modern constitutional framework for the Crown's duty to consult and, where appropriate, accommodate Aboriginal interests before final proof of an asserted Aboriginal right or title. The duty is grounded in the honour of the Crown and arises when the Crown has knowledge, real or constructive, of a potential Aboriginal right or title and contemplates conduct that may adversely affect it. The depth of consultation varies with the strength of the claim and the seriousness of the potential adverse impact. The Crown must consult in good faith, but there is no general duty to reach agreement in every case.
13. Aboriginal Title — Tsilhqot'in Nation (2014)
Tsilhqot'in Nation was the first Supreme Court of Canada decision to grant a declaration of Aboriginal title over a specific tract of land. The judgment provided important guidance on the nature of Aboriginal title, the evidentiary requirements for establishing title and the constitutional consequences of government infringement of established title.
14. Federalism — Reference re Securities Act (2011)
The Supreme Court rejected a federal attempt to establish a comprehensive national securities regulator under the federal trade and commerce power on the record before it. The decision is an important modern federalism precedent emphasizing the constitutional division of powers and the need to identify the true character of legislation rather than allowing a broad federal head of power to swallow provincial jurisdiction.
15. Administrative Law — Canada (Minister of Citizenship and Immigration) v. Vavilov (2019)
Vavilov is one of the Court's leading modern administrative-law decisions. It established a revised framework for judicial review of administrative decisions, with reasonableness as the presumptive standard and correctness applying in defined categories. The decision emphasizes justification, transparency and intelligibility as central elements of reasonableness review.
16. Privacy and Informational Expectations — R. v. Tessling and Modern Technology
Tessling remains useful for understanding how Section 8 analysis asks what information technology actually reveals rather than assuming every technologically collected datum attracts the same constitutional protection. Later cases have expanded Canadian privacy jurisprudence in relation to computers, phones and digital information, so Tessling should be read as one part of a larger evolving Section 8 body of law.
17. Foundational Constitutional Interpretation — Edwards / Persons Case (1929)
The Persons Case concerned whether women were 'qualified persons' eligible for appointment to Canada's Senate. The Judicial Committee of the Privy Council held that women were included within the relevant constitutional term and used the famous 'living tree' metaphor for constitutional interpretation. This is a foundational Canadian constitutional decision, but it is not an SCC decision. The SCC's earlier answer had been reversed on appeal to the Privy Council. Because the Supreme Court did not become Canada's final court until 1949, historical guides should distinguish pre-1949 Privy Council decisions from modern SCC judgments.
