The Liberal Party of Canada (LPC; French: Parti libéral du Canada, PLC) is a federal political party in Canada. The Liberal Party espouses the principles of liberalism, and generally sits at the centre to centre-left of the Canadian political spectrum, with their main rival, the Conservative Party, positioned to their right and the New Democratic Party positioned to their left. The party is often described as a "big tent", practising "brokerage politics", attracting support from a broad spectrum of voters. The Liberal Party is the oldest active federal political party in the country, and has dominated the federal politics of Canada for much of its history. As a result, it has sometimes been referred to as Canada's "natural governing party". It has been the governing party since 2015; Mark Carney has been its leader and the Prime Minister of Canada since March 2025.
The party has been in continual existence since the confederation of Canada in 1867. The party first came into power in 1873, with the party's first official leader Alexander Mackenzie leading the nation for five years. Following close to 20 years in opposition, Wilfrid Laurier led the party to victory in 1896 and facilitated many compromises between English and French Canada that shaped the bilingual nation during his 15-year premiership. During William Lyon Mackenzie King's 29 years as party leader, the party was in government from 1921 to 1926, from 1926 to 1930, and from 1935 to 1948. In the half century between 1935 and 1984, the party was in power for all but seven years, winning elections under King, Louis St. Laurent, Lester B. Pearson, and Pierre Trudeau, leading the country through a period of significant expansion of the Canadian welfare state and the emergence of Canada as an independent voice in international affairs. In more recent decades, the party was in government from 1993 to 2006 led by Jean Chrétien and then Paul Martin, leaders who combined social liberalism with fiscal conservatism through a Third Way philosophy. It suffered its worst electoral defeat in 2011, the only federal election as of 2026 in which the Liberals failed to attain the status of government or Official Opposition. The party returned to power in 2015 led by Justin Trudeau, son of the previous Prime Minister Trudeau. Trudeau was succeeded by Mark Carney as party leader in March 2025, who was appointed Prime Minister that month and, in the 2025 federal election, garnered the highest vote share of any party since 1984.
The Liberals' signature policies and legislative decisions include Canadian citizenship, universal health care, the Canada Pension Plan, Canada Student Loans, the establishment of the Royal Canadian Navy in 1910, the unification of the armed forces in 1968, Canadian peacekeeping, the creation of the Maple Leaf flag, official bilingualism and multiculturalism, the patriation of the Constitution of Canada and the establishment of the Canadian Charter of Rights and Freedoms, the Clarity Act, gun control, expanded access to abortion, the legalization of same-sex marriage and of medical assistance in dying, campaign and political finance reform, national carbon pricing, a national early learning and child care program, a national school lunch program, the Canadian Dental Care Plan, and the beginning of national pharmacare.

History
19th century
The Liberals are descended from the mid-19th century Reformers who advocated for responsible government throughout British North America. These included George Brown, Alexander Mackenzie, Robert Baldwin, William Lyon Mackenzie and the Clear Grits in Upper Canada, Joseph Howe in Nova Scotia, and the Patriotes and Rouges in Lower Canada led by figures such as Louis-Joseph Papineau. The Clear Grits and Parti rouge sometimes functioned as a united bloc in the legislature of the Province of Canada beginning in 1854, but a united Liberal Party combining both English and French Canadian members was not formed until 1867. Their lineage from the Clear Grits led to modern Liberals being nicknamed "Grits".
At the time of Confederation of the former British colonies of Canada (now Ontario and Quebec), New Brunswick, and Nova Scotia, the radical Liberals were marginalized by the more pragmatic Conservative coalition assembled under Sir John A. Macdonald. In the 29 years after Confederation, the Liberals were consigned to opposition, with the exception of one stint in government. Alexander Mackenzie was the de facto leader of the Official Opposition after Confederation and finally agreed to become the first official leader of the Liberal Party in 1873. He was able to lead the party to power for the first time in 1873, after the Macdonald government resigned over the Pacific Scandal. Mackenzie subsequently won the 1874 election and served as prime minister for an additional four years. During the five years the Liberal government brought in many reforms, including the replacement of open voting by secret ballot, confining elections to one day and the creation of the Supreme Court of Canada, the Royal Military College of Canada, and the Office of the Auditor General; however, the party was only able to build a solid support base in Ontario and in 1878 lost the government to Macdonald. The Liberals would spend the next 18 years in opposition.
In their early history, the Liberals were the party of continentalism and opposition to imperialism. The Liberals also became identified with the aspirations of Quebecers as a result of the growing hostility of French Canadians to the Conservatives. The Conservatives lost the support of French Canadians because of the role of Conservative governments in the execution of Louis Riel and their role in the Conscription Crisis of 1917, and especially their opposition to French schools in provinces besides Quebec.
It was not until Wilfrid Laurier became leader that the Liberal Party emerged as a modern party. Laurier was able to capitalize on the Conservatives' alienation of French Canada by offering the Liberals as a credible alternative. Laurier was able to overcome the party's reputation for anti-clericalism that offended the still-powerful Quebec Roman Catholic Church. In English-speaking Canada, the Liberal Party's support for reciprocity made it popular among farmers, and helped cement the party's hold in the growing prairie provinces.
20th century
Until the early part of the century, the Liberal Party was a loose coalition of local, provincial, and regional bodies with a strong national party leader and caucus, but with an informal and regionalized extra-parliamentary organizational structure. There was no national membership of the party. An individual became a member by joining a provincial Liberal party. Laurier called the party's first national convention in 1893 to unite Liberal supporters behind a programme and build the campaign that successfully brought the party to power in 1896, but no efforts were made to create a formal national organization outside Parliament.
As a result of the party's defeats in the 1911 and 1917 federal elections, Laurier attempted to organize the party on a national level by creating three bodies: the Central Liberal Information Office, the National Liberal Advisory Committee, and the National Liberal Organization Committee. However, the advisory committee became dominated by members of Parliament and all three bodies were underfunded and competed with both local and provincial Liberal associations and the national caucus for authority. The party did organize the national party's second convention in 1919 to elect William Lyon Mackenzie King as Laurier's successor (Canada's first leadership convention), yet following the party's return to power in the 1921 federal election the nascent national party organizations were eclipsed by powerful ministers and local party organizations largely driven by patronage.
As a result of both the party's defeat in the 1930 federal election and the Beauharnois scandal, which highlighted the need for distance between the Liberal Party's parliamentary wing and campaign fundraising, a central coordinating organization, the National Liberal Federation, was created in 1932 with Vincent Massey as its first president. With the Liberal return to power, the national organization languished except for occasional national committee meetings, such as in 1943 when Mackenzie King called a meeting of the federation (consisting of the national caucus and up to seven voting delegates per province) to approve a new platform for the party in anticipation of the end of World War II and prepare for a post-war election. No national convention was held, however, until 1948; the Liberal Party held only three national conventions prior to the 1950s – in 1893, 1919 and 1948. The National Liberal Federation remained largely dependent on provincial Liberal parties and was often ignored and bypassed the parliamentary party in the organization of election campaigns and the development of policy. With the defeat of the Liberals in the 1957 federal election and in particular 1958, reformers argued for the strengthening of the national party organization so it would not be dependent on provincial Liberal parties and patronage. A national executive and Council of presidents, consisting of the presidents of each Liberal riding association, were developed to give the party more co-ordination and national party conventions were regularly held in biennially where previously they had been held infrequently. Over time, provincial Liberal parties in most provinces were separated from provincial wings of the federal party and in a number of cases disaffiliated. By the 1980s, the National Liberal Federation was officially known as the Liberal Party of Canada.
21st century
Martin succeeded Chrétien as party leader and prime minister in 2003. Despite the personal rivalry between the two, Martin was Minister of Finance during the 1990s and was the architect of the Liberals' economic policies. Chrétien left office with a high approval rating and Martin was expected to make inroads into Quebec and Western Canada, two regions of Canada where the Liberals had not attracted much support since the 1980s and 1990s, respectively.
The political situation changed with the revelation of the sponsorship scandal, in which advertising agencies supporting the Liberal Party received grossly inflated commissions for their services. Having faced a divided conservative opposition for the past three elections, Liberals were seriously challenged by competition from the newly united Conservative Party led by Stephen Harper. The infighting between Martin and Chrétien's supporters also dogged the party. Nonetheless, by criticizing the Conservatives' social policies, the Liberals were able to draw progressive votes from the NDP, which made the difference in several close races. In the 2004 election, the Liberals retained enough support to continue as the government, though they were reduced to a minority.
In the midst of various court rulings in 2003 and 2004 that allowed for the legalization of same-sex marriage in seven provinces and one territory, the Martin government proposed a bill to legalize same-sex marriage across Canada. The House of Commons passed the Civil Marriage Act in late June 2005 in a late-night, last-minute vote before Parliament closed down, the Senate passed it in July 2005, and it received Royal Assent on July 20. This made Canada the fourth country in the world to allow same-sex marriages. In November 2005, the Martin government brokered a deal between first ministers and aboriginal leaders known as the Kelowna Accord, which sought to improve the education, skills training, housing and health care of aboriginal peoples by providing $5 billion in funding over five years.
Following the release of the first Gomery Report, the Liberals dropped in polls. Nonetheless, Martin turned down the NDP's conditions for continued support, as well as rejecting an opposition proposal which would schedule a February 2006 election in return for passing several pieces of legislation. The Liberals thus lost a confidence vote on November 28, and Martin advised Governor General Michaëlle Jean to dissolve Parliament and call an election for January 2006.
Systems and realignment model
Scholars and political experts have recently used a political realignment model to explain what was considered a collapse of a dominant party and put its condition in long-term perspective. According to recent scholarship, there have been four party systems in Canada at the federal level since Confederation, each with its own distinctive pattern of social support, patronage relationships, leadership styles, and electoral strategies. Steve Patten identifies four party systems in Canada's political history:
The first party system emerged from pre-Confederation colonial politics, had its "heyday" from 1896 to 1911 and lasted until the Conscription Crisis of 1917, and was characterized by local patronage administered by the two largest parties, the Liberals and the Conservatives.
The second system emerged following the First World War, and had its heyday from 1935 and 1957, was characterized by regionalism and saw the emergence of several protest parties, such as the Progressives, the Social Credit Party, and the Co-operative Commonwealth Federation.
The third system emerged in 1963 and had its heyday from 1968 to 1983 and began to unravel thereafter. The two largest parties were challenged by a strong third party, the New Democratic Party (successor to the CCF). Campaigns during this era became more national in scope because of electronic media, and involved a greater focus on leadership. The dominant policy of the era was Keynesian economics.
The fourth party system has involved the rise of the Reform Party, the Bloc Québécois, and the merger of the Canadian Alliance with the Progressive Conservatives. Most parties moved to one-member-one-vote leadership contests, and campaign finance laws were reformed in 2004. The fourth party system has been characterized by market-oriented policies that generally abandoned Keynesian policies but maintained the welfare state.
Stephen Clarkson (2005) shows how the Liberal Party has dominated all the party systems, using different approaches. It began with a "clientelistic approach" under Laurier, which evolved into a "brokerage" system of the 1920s, 1930s and 1940s under Mackenzie King. The 1950s saw the emergence of a "pan-Canadian system", which lasted until the 1990s. The 1993 election – categorized by Clarkson as an electoral "earthquake" which "fragmented" the party system, saw the emergence of regional politics within a four party-system, whereby various groups championed regional issues and concerns. Clarkson concludes that the inherent bias built into the first-past-the-post system, has chiefly benefited the Liberals.
Principles and policies
The principles of the party are based on liberalism as defined by various liberal theorists and include individual freedom for present and future generations, responsibility, human dignity, a just society, political freedom, religious freedom, national unity, equality of opportunity, cultural diversity, bilingualism, and multilateralism. From the early twentieth century, the Liberal Party has favoured a variety of "big tent" policies from both right and left of the political spectrum. When it formed the government from 1993 to 2006, it championed balanced budgets, and eliminated the budget deficit completely from the federal budget in 1995 by reducing spending on social programs or delegating them to the provinces, and promised to replace the Goods and Services Tax in the party's famous Red Book. It also federally legalized same-sex marriage in 2005.
The Liberal Party has historically been the primary architect and champion of the country's official multiculturalism policy. Historically, Canadian immigration policy openly favored immigrants of Caucasian ancestry from the United States, Britain, and Europe. The Liberal government of the 1960s was responsible for dismantling this racially biased system. The shift to race-neutral immigration admissions criteria in Canada was a landmark policy change that began in 1962 and culminated with the introduction of the points-based immigration system in 1967 under the Liberal government. During Pierre Trudeau's time as Prime Minister (1968–1979, 1980–1984), Canada's immigration levels were much lower and more stable, with total arrivals often in the tens of thousands annually, contrasting sharply with current figures. The government introduced official immigration quotas in the mid-1970s, with a target of 100,000 in 1979. In 2017, the Liberal government announced Canada would welcome nearly one million immigrants over the next three years. A record 483,390 immigrants were admitted in 2024.
2021 party platform
During the 2021 federal election, the Liberal Party of Canada introduced their platform, which included a "Gender and Diversity Impact Summary" for each chapter, as well as six key categories. These included: the pandemic, housing, health care, the economy, climate change, and reconciliation.
Key Liberal policies of the 2021 platform included:
Requiring travellers on interprovincial trains, commercial flights, cruise ships, and other federally regulated vessels be vaccinated against COVID-19.
An investment of $6 billion—on top of $4 billion already committed—to support the elimination of health system waitlists.
Providing various investments in order to build, preserve, or revitalize 1.4 million new homes by 2025–26.
Allocating funds to spend $2 billion over the next five years on measures to address the legacy of residential schools with "truth, justice, and healing" initiatives.
Re-introducing legislation within the first 100 days in office to eliminate the practice of gay conversion therapy for everyone.
Achieving net-zero emissions by 2050.
Presenting a National Action Plan on Combating Hate by 2022 as part of a renewed Anti-Racism Strategy, including the Black Canadians Justice Strategy.
Updating the committed number to receive 40,000 Afghan refugees.
Creating a minimum tax rule so that everyone who earns enough to qualify for the top bracket pays at least 15% each year (the tax rate paid by people earning less than $49,000), removing their ability to artificially pay no tax through excessive use of deductions and credits.
2025 party platform
The Liberal Party's policies during the 2025 election included:
Strengthening border security with new Canada Border Services Agency officers, drones, and K-9 teams to monitor shipments.
Reinstating the zero-emissions vehicle subsidy program and introducing an adjustable carbon import tax to tax goods from countries that don't have comparable carbon pricing schemes. The party is favourable to new pipelines and energy projects but will allow Quebec to veto new pipelines on its territory.
Cutting income taxes for the lowest tax bracket, cancelling a proposed increase in the capital gains inclusion rate, and eliminating the Goods and Services Tax on homes that cost less than $1 million for new buyers.
Increasing the guaranteed income supplement and easing access to employment insurance.
Recruiting new RCMP personnel, increasing funding for the Public Prosecution Service, and making it harder for people charged with violent crimes to get bail.
Increasing defence spending to meet the NATO commitment of 2% of GDP by 2030.
Expanding diplomatic activities to strengthen ties with foreign allies in pursuit of a "full foreign policy" and maintaining the annual foreign aid budget at $800 million.
Cutting government spending by shrinking the public service and aiming to balance the government's operational spending within 3 years.
Creating a new standalone entity called Build Canada Homes to oversee the construction of affordable housing, which would supply $25 billion in debt and $1 billion in equity financing to prefabricated home builders.
Provincial parties
Seven provinces and one territory in Canada have a "Liberal Party" in their legislatures. Neither Nunavut nor the Northwest Territories have party-based electoral and governing systems (both operate with consensus democracy). British Columbia had a Liberal Party whose name and ideology have shifted, BC United; Saskatchewan also had a Liberal Party whose name has changed, Saskatchewan Progress Party. Yukon, Alberta, Manitoba, Ontario and Quebec each have a Liberal Party that may align ideologically with the federal party but operates as a completely separate entity (though at one time were affiliated): Those provincial parties have separate policies, finances, memberships, constituency associations, executives, conventions and offices. The New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island provincial Liberals are each semi-affiliated with the federal Liberal Party.
Election results
The Liberal Party has been one of two principal contenders for power for most of Canada's history, most often with the Conservative Party (or its predecessor parties) as the primary rival. It is often referred to as Canada's "natural governing party" due to its electoral success and endurance. The Liberal Party had formed government following 26 of 45 federal elections since the confederation of Canada in 1867, leading the national government for almost 60% of the time throughout the nation's history. Only once did it fail to form either the government or the official opposition.
