TheSupreme Court of Canada (SCC;French:Cour suprême du Canada,CSC) is thehighest court in thejudicial system ofCanada. It comprisesnine justices, whose decisions are the ultimate application ofCanadian law, and grants permission to between 40 and 75litigants each year to appeal decisions rendered by provincial, territorial and federalappellate courts. The Supreme Court is bijural, hearing cases from two major legal traditions (common law andcivil law) and bilingual, hearing cases in bothofficial languages of Canada (English and French).[2]
The effects of any judicial decision on the common law, on the interpretation of statutes, or on any other application of law, can, in effect, be nullified by legislation, unless the particular decision of the court in question involves application of theCanadian Constitution, in which case, the decision (in most cases) is completely binding on the legislative branch.[3] This is especially true of decisions which touch upon theCanadian Charter of Rights and Freedoms, which cannot be altered by the legislative branch unless the decision is overridden pursuant tosection 33 (the "notwithstanding clause").
The authority to establish a national appeal court dated back to the creation of theProvince of Canada in 1840, but the power remained unused.[4] When theBritish North America Act, 1867,[a] was finalized,section 101 providedParliament may create a general court of appeal.[5][ps 1] Prime MinisterJohn A. Macdonald introduced two bills to establish the supreme court in 1869 and 1870, however, both were withdrawn.[6][7][ps 2][ps 3]
During the1874 federal election,Alexander Mackenzie'sLiberals included the creation of a central court of appeal as part of their campaign platform.Minister of JusticeTélésphore Fournier introduced theThe Supreme and Exchequer Court Act, which passed on April 8, 1875, with bipartisan support. The Act simultaneously established both the Supreme Court and theExchequer Court.[8][9][ps 4]
However, prior to 1949, the Supreme Court did not constitute thecourt of last resort: litigants could appeal the Court's decisions to theJudicial Committee of the Privy Council in London. Some cases could bypass the Supreme Court and go directly to the Judicial Committee from the provincial courts of appeal.[10] The Supreme Court formally became the court of last resort for criminal appeals in 1933[11][ps 5] and for all other appeals in 1949.[12][ps 6] Cases that were begun prior to those dates remained appealable to the Judicial Committee, and the last case on appeal from the Supreme Court of Canada was not decided until 1959.[13][ps 7]
The increase in the importance of the Supreme Court was mirrored by the numbers of its members. When the Court was established in 1875, it operated with apanel of six judges, with aquorum of four, meaning that if there was an equal division (3–3), the appeal would be dismissed.[14][15] In 1927, Parliament amended theSupreme Court Act to add a seventh position on the Court and to establish amandatory retirement age of 75.[16][ps 8] In 1949, the bench reached its current composition of nine justices.[17]
Prior to 1949, most of the appointees to the court owed their position to politicalpatronage.[18] Each judge had strong ties to the party in power at the time of their appointment. In 1973, the appointment of a constitutional law professorBora Laskin as chief justice represented a major turning point for the court.[19] Laskin'sfederalist and liberal views were shared byPrime MinisterPierre Trudeau, who recommended Laskin's appointment to the court, but from that appointment onward appointees increasingly either came from academic backgrounds or were well-respected practitioners with several years' experience in appellate courts.[18]
TheConstitution Act, 1982, greatly expanded the role of the court in Canadian society by the addition of theCanadian Charter of Rights and Freedoms, which greatly broadened the scope of judicial review. The evolution from the court under Chief JusticeBrian Dickson (1984–1990) through to that ofAntonio Lamer (1990–2000) witnessed a continuing vigour in the protection of civil liberties. Lamer's criminal law background proved an influence on the number of criminal cases heard by the Court during his time as chief justice. Nonetheless, the Lamer court was more conservative withCharter rights, with only about a 1% success rate forCharter claimants.[20]
Lamer was succeeded as the chief justice byBeverley McLachlin in January 2000. She was the first woman to hold that position.[21] McLachlin's appointment resulted in a more centrist and unified court. Dissenting and concurring opinions were fewer than during the Dickson and Lamer courts. With the 2005 appointments of puisne justicesLouise Charron andRosalie Abella, the court became the world's most gender-balanced national high court with four of its nine members being female.[22][23] JusticeMarie Deschamps's possessive retirement on 7 August 2012 caused the number to fall to three;[24] however, the appointment ofSuzanne Côté on 1 December 2014 restored the number to four. The appointment ofMary T. Moreau on 6 November 2023 created the first female-majority in the history of the Court.[25][26] After serving on the court for28 years, 259 days (17 years, 341 days as chief justice), McLachlin retired in December 2017. Her successor as the chief justice isRichard Wagner.
Along with theGerman Federal Constitutional Court and theEuropean Court of Human Rights, the Supreme Court of Canada is among the most frequently cited courts in the world.[27]: 21, 27–28

The structure of theCanadian court system is pyramidal, a broad base being formed by the various provincial and territorial courts whose judges are appointed by the provincial or territorial governments.[28] At the next level are the provincial and territorial superior trial courts, where judges are appointed by the federal government.[2] Judgments from the superior courts may be appealed to a still higher level, the provincial or territorial superior courts of appeal.
Several federal courts also exist: theTax Court, theFederal Court, theFederal Court of Appeal, and theCourt Martial Appeal Court. Unlike the provincial superior courts, which exercise inherent or generaljurisdiction, the jurisdiction of federal courts and provincially appointed provincial courts are limited by statute.[9] In all, there are over 1,000 federally appointed judges at various levels across Canada.[citation needed]
The Supreme Court rests at the apex of the judicial pyramid. This institution hears appeals from the provincial courts of last resort, usually the provincial or territorial courts of appeal, and the Federal Court of Appeal.[28] In some matters appeals come straight from the trial courts, as in the case ofpublication bans and other orders that are otherwise not appealable.[29]
In most cases, permission to appeal must first be obtained from the court. Motions forleave to appeal to the court are generally heard by a panel of three of its judges and a simple majority is determinative. By convention, this panel never explains why it grants or refuses leave in any particular case, but the court typically hears cases of national importance or where the case allows it to settle an important issue of law. Leave is rarely granted, meaning that for most litigants, provincial courts of appeal are courts of last resort. But leave to appeal is not required for some cases, primarily indictable criminal cases in which at least one appellate judge (on the relevant provincial court of appeal) dissented on a point of law, and appeals from provincialreference cases.
A final source of cases is the power of the federal government to submit reference cases. In such cases, the Supreme Court is required to give an opinion on questions referred to it by the Governor in Council (theCabinet). However, in many cases, including the most recentsame-sex marriage reference, the Supreme Court has declined to answer a question from the Cabinet. In that case, the court said it would not decide ifsame-sex marriages were required by theCharter of Rights and Freedoms, because the government had announced it would change the law regardless of its opinion, and subsequently did.
The Supreme Court thus performs a unique function. It can be asked by the Governor-in-Council to hear references considering important questions of law. Such referrals may concern the constitutionality or interpretation of federal or provincial legislation, or thedivision of powers between federal and provincial spheres of government. Any point of law may be referred in this manner. However, the Court is not often called upon to hear references. References have been used to re-examine criminal convictions that have concerned the country as in the cases ofDavid Milgaard andSteven Truscott.
The Supreme Court has the ultimate power ofjudicial review over Canadian federal and provincial laws' constitutional validity. If a federal or provincial law has been held contrary to the division of power provisions of one of the various constitution acts, the legislature or parliament must either live with the result, amend the law so that it complies, or obtain an amendment to the constitution. If a law is declared contrary to certain sections of theCharter of Rights and Freedoms, Parliament or the provincial legislatures may make that particular law temporarily valid again against by using the "override power" of thenotwithstanding clause. In one case, theQuebec National Assembly invoked this power to override a Supreme Court decision (Ford v Quebec (AG)) that held that one of Quebec's language laws banning the display of English commercial signs was inconsistent with theCharter. Saskatchewan has also used it to uphold its labour laws. This override power can be exercised for five years, after which time the override must be renewed or the decision comes into force.
In some cases, the court may stay the effect of its judgments so that unconstitutional laws continue in force for a period of time. Usually, this is done to give Parliament or a legislature sufficient time to enact a new replacement scheme of legislation. For example, inReference Re Manitoba Language Rights, the court struck down Manitoba's laws because they were not enacted in the French language, as required by the Constitution. However, the Court stayed its judgment for five years to give Manitoba time to re-enact all its legislation in French. It turned out five years was insufficient so the court was asked, and agreed, to give more time.
Constitutional questions may, of course, also be raised in the normal case of appeals involving individual litigants, governments, government agencies orCrown corporations. In such cases the federal and provincial governments must be notified of any constitutional questions and mayintervene to submit abrief and attendoral argument at the court. Usually the other governments are given the right to argue their case in the court, although on rare occasions this has been curtailed and prevented by order of one of the court's judges.
The Supreme Court sits in three sessions in each calendar year. The first session begins on the fourth Tuesday in January, the second session on the fourth Tuesday in April, and the third session on the first Tuesday in October. The Court determines how long each session will be. Hearings only take place inOttawa[30], although litigants can present oral arguments from remote locations by means of a video-conference system. Hearings are open to the public. Most hearings are taped for delayed telecast in both of Canada's official languages. When in session, the court sits Monday to Friday, hearing two appeals a day. A quorum consists of five members for appeals, but a panel of nine justices hears most cases.[ps 9]
On the bench, thechief justice of Canada or, in his or her absence, the seniorpuisne justice, presides from the center chair with the other justices seated to his or her right and left by order of seniority of appointment. At sittings, the justices usually appear in black silk robes but they wear their ceremonial robes of bright scarlet trimmed with Canadian white mink in court on special occasions and in the Senate at the opening of each new session of Parliament.[citation needed]
Counsel appearing before the court may use either English or French. The judges can also use either English or French. There is simultaneous translation available to the judges, counsel and to members of the public who are in the audience, or watching by livestream.
The decision of the court is sometimes rendered orally at the conclusion of the hearing. In these cases, the court may simply refer to the decision of the court below to explain its own reasons. In other cases, the court may announce its decision at the conclusion of the hearing, with reasons to follow.[ps 10][ps 11][ps 12] As well, in some cases, the court may not call on counsel for the respondent, if it has not been convinced by the arguments of counsel for the appellant.[ps 13] In very rare cases, the court may not call on counsel for the appellant and instead calls directly on counsel for the respondent.[ps 14] However, in most cases, the court hears from all counsel and then reserves judgment to enable the justices to write considered reasons. Decisions of the court need not be unanimous – a majority may decide, with dissenting reasons given by the minority. Justices may write separate or joint opinions for any case.
Since 1970 and the introduction of theOfficial Languages Act, all judgments of the Court are fully bilingual, released in both official languages. Prior to 1970, the decisions were written in the language of the individual judges. If only one judge wrote a decision, it would be in the language chosen by that judge. If more than one judge wrote reasons in a case, there could be a mixture of English and French reasons. In July 2025, the Court announced that it will begin the process of translating the 6,000 judgments which were rendered prior to 1970, so that eventually the entire set of the Court's reasons will be bilingual. The translation will begin with a list of 25 judgments selected by an advisory panel as some of the most significant cases.[31]
A puisne justice of the Supreme Court isreferred to asTheHonourable Mr/Madam Justice and the chief justice asRight Honourable. At one time, judges were addressed as "My Lord" or "My Lady" during sessions of the court, but it has since discouraged this style of address and has directed lawyers to use the simpler "Justice", "Mr Justice" or "Madam Justice".[32] The designation "My Lord/My Lady" continues in many provincial superior courts and in the Federal Court of Canada and Federal Court of Appeal, where it is optional.
Every four years, theJudicial Compensation and Benefits Commission makes recommendations to the federal government about the salaries for federally appointed judges, including the judges of the Supreme Court. That recommendation is not legally binding on the federal government, but the federal government is generally required to comply with the recommendation unless there is a very good reason to not do so.[ps 15] The chief justice receives $370,300 while the puisne justices receive $342,800 annually.[ps 16]
Justices of the Supreme Court of Canada are appointed by thegovernor general on theadvice of the prime minister.[33]
Eligibility requirements for appointment to the Court are provided under theSupreme Court Act, which requires that appointees be judges of a superior court or members of thebar for ten or more years. Members of the bar or superior judiciary of Quebec, by law, must hold three of the nine positions on the Supreme Court of Canada.[ps 17] This is justified on the basis that Quebec usescivil law, rather thancommon law, as in the rest of the country. As explained in the reasons inReference Re Supreme Court Act, ss. 5 and 6, sitting judges of the Federal Court and Federal Court of Appeal cannot be appointed to any of Quebec's three seats. By convention, the remaining six positions are divided in the following manner: three from Ontario, two from the western provinces and one from the Atlantic provinces.[34] Parliament and the provincial governments have no constitutional role in such appointments, sometimes a point of contention.[35]
In 2006, an interview phase by anad hoc committee of members of Parliament was added. JusticeMarshall Rothstein became the first justice to undergo the new process. The prime minister still has the final say on who becomes the candidate that is recommended to the governor general for appointment to the court. The government proposed an interview phase again in 2008, but a general election and minority parliament intervened with delays such that the Prime Minister recommendedJustice Cromwell after consulting theleader of the Opposition.[36]
As of August 2016, Prime MinisterJustin Trudeau opened the process of application to change from the above-noted appointment process. Under the revised process, "[any] Canadian lawyer or judge who fits specified criteria can apply for a seat on the Supreme Court, through the Office of the Commissioner for Federal Judicial Affairs."[37][38] Functionalbilingualism is now a requirement.[39][40][41]
Justices were originally allowed to remain on the bench forlife, but in 1927 amandatory retirement age of 75 was instituted. They may choose to retire earlier, but can only be removed involuntarily before that age by a vote of theSenate andHouse of Commons.[ps 18][ps 19]
The current chief justice of Canada is Richard Wagner. He was appointed to the court as a puisne judge on 5 October 2012 and appointed chief justice, 18 December 2017.[42] The nine justices of the Wagner Court are:
The following graphical timeline depicts the length of each current justice's tenure on the Supreme Court (not their position in the court's order of precedence) as of 24 October 2025.
Andromache Karakatsanis has had the longest tenure of any of the current members of the court, having been appointed in October 2011. Richard Wagner's cumulative tenure is13 years, 19 days—5 years, 74 days as puisne justice, and7 years, 310 days as chief justice. Mary Moreau has the briefest tenure, having been appointed1 year, 352 days ago. The length of tenure for the other justices are: Suzanne Côté,10 years, 327 days; Malcom Rowe,8 years, 361 days; Sheilah Martin,7 years, 310 days; Nicholas Kasirer,6 years, 38 days; Mahmud Jamal,4 years, 115 days; and Michelle O'Bonsawin,3 years, 53 days.
TheRules of the Supreme Court of Canada are located on the laws-lois.justice.gc.ca website,[51] as well as in theCanada Gazette, as SOR/2002-216 (plus amendments), made pursuant to subsection 97(1) of theSupreme Court Act. Fees and taxes are stipulated near the end.
Since 1967, the court has hiredlaw clerks to assist in legal research. Between 1967 and 1982, each puisne justice was assisted by one law clerk and the chief justice had two. From 1982, the number was increased to two law clerks for each justice.[52] Currently, each justice has up to three law clerks.[53]
The Supreme Court of Canada Building (French:L'édifice de la Cour suprême du Canada) is located just west ofParliament Hill, at 301Wellington Street. It is situated on a bluff high above theOttawa River indowntown Ottawa and is home to the Supreme Court of Canada.[54] It also contains two courtrooms used by the Federal Court and theFederal Court of Appeal.
The building was designed byErnest Cormier and is known for itsArt Deco style[55]—including two candelabrum-style fluted metal lamp standards that flank the entrance and the marble walls and floors of the lobby[56]—contrasting with thechâteauesque roof. Construction began in 1939, with the cornerstone laid byQueen Elizabeth, consort of KingGeorge VI and later known as the Queen Mother. In her speech, she said, "perhaps it is not inappropriate that this task should be performed by a woman; for woman's position in a civilized society has depended upon the growth of law."[57] The court began hearing cases in the new building by January 1946.
In 2000, the edifice was named by theRoyal Architectural Institute of Canada as one of the top 500 buildings produced in Canada during the last millennium.[58]Canada Post issued a commemorative stamp on 9 June 2011, as part of the Architecture Art Déco series.[56]
Two flagstaffs have been erected in front of the building. A flag on one is flown daily, while the other is hoisted only on those days when the court is in session. Also located on the grounds are several statues, including one of Prime MinisterLouis St. Laurent, byElek Imredy in 1976, and two—Veritas (Truth) andJustitia (Justice)—by Canadian sculptorWalter S. Allward. Inside there are busts of several chief justices:John Robert Cartwright (1967–1970), Bora Laskin (1973–1983), Brian Dickson (1984–1990), and Antonio Lamer (1990–2000), all sculpted by Kenneth Phillips Jarvis, a retired Under Treasurer of theLaw Society of Upper Canada.[59]
The court was previously housed in theRailway Committee Room and a number of other committee rooms in theCentre Block on Parliament Hill.[60] The court then sat in theOld Supreme Court building on Bank Street, between 1889 and 1945. That structure was demolished in 1955 and the site used as parking for Parliament Hill.
Accordingly, the Supreme Court of Canada, the German Federal Constitutional Court, and the European Court of Human Rights have emerged as three of the most frequently cited courts in the world.
