Dominic LeBlanc

Early life and education

LeBlanc was born in 1967, of Acadian descent, at the Ottawa Civic Hospital in Ottawa, Ontario, to Joslyn "Lyn" ( Carter) and Roméo LeBlanc, a former MP, senator and 25th governor general of Canada. At the time, his father was press secretary to Prime Minister Lester B. Pearson.

As a child, he baby-sat the children of then-prime minister Pierre Trudeau, including Justin Trudeau. He remained friends with Justin Trudeau and endorsed Trudeau's candidacy for Liberal leader in 2012.

LeBlanc attended Lisgar Collegiate Institute in Ottawa for high school. He earned a Bachelor of Arts degree in political science from the University of Toronto (Trinity College) and a Bachelor of Laws degree from the University of New Brunswick, and then attended Harvard Law School, where he obtained his Master of Laws degree. LeBlanc worked as a barrister and solicitor with Clark Drummie in Shediac and Moncton. From 1993 to 1996, LeBlanc was a Special Advisor to Prime Minister Jean Chrétien.

Political career (1997–present)

LeBlanc is member of the Liberal Party of Canada in the House of Commons of Canada, representing the riding of Beauséjour in New Brunswick.

LeBlanc first ran for election in that riding in 1997, losing to New Democratic Party candidate Angela Vautour. During that race there were accusations of political patronage as LeBlanc's father was the sitting viceroy, and there was criticism that the governor general had a series of events planned in New Brunswick during the week that the election writs dropped.

In 2000 LeBlanc once again ran against Vautour, who had crossed the floor to join the Progressive Conservative party, and was elected. LeBlanc was re-elected in 2004 (where he faced Vautour for a third time), 2006, 2008, 2011, 2015, 2019, and 2021.

Chrétien and Martin governments

During the Liberal Party's time in power LeBlanc served as Parliamentary Secretary to the Minister of National Defence, from January 13, 2003, to December 11, 2003, and was the chair of the Atlantic Caucus.

On July 10, 2004, he was sworn in as a member of the Privy Council for Canada and appointed Parliamentary Secretary to the leader of the Government in the House of Commons and Deputy Chief Government Whip. He has served on the Special Committee on Non-Medical Use of Drugs, and the Standing Committees on Fisheries and Oceans, Transport and Government Operations, National Defence and Veterans Affairs, Public Accounts, Procedures and House Affairs, International Trade, and Justice and Human Rights.

In opposition

In January 2006, he was named Official Opposition critic for international trade and later that year he was co-chair of the 2006 Liberal Party leadership convention in Montreal. In January 2007, he was named by the Honourable Stéphane Dion, Vice Chair – Liberal Party of Canada Policy and Platform Committee and In October of that year, he was named Official Opposition critic for intergovernmental affairs. In January 2009, he was named by Michael Ignatieff as the critic for justice and attorney general. Before the return of Parliament in September 2010, Ignatieff shuffled his Shadow Cabinet and appointed LeBlanc as the Liberal critic for national defence. Following LeBlanc's re-election in the 2011 federal election, interim Liberal leader Bob Rae appointed LeBlanc as the Liberal Party's foreign affairs critic.

2008 leadership bid

Main article: 2009 Liberal Party of Canada leadership election

On October 27, 2008, LeBlanc was the first candidate to officially announce his intention to seek the leadership of the Liberal party to replace Stéphane Dion. Former leadership candidates Michael Ignatieff and Bob Rae came forward shortly after LeBlanc's announcement. His supporters included top staffers in the prime minister's office under Jean Chrétien, such as his former chief of staff Percy Downe, and Tim Murphy, chief of staff under Paul Martin. Some senior organizers in Gerard Kennedy's 2006 leadership bid also supported LeBlanc.

On December 8, 2008, LeBlanc announced he was dropping out of the leadership race because he felt a new leader needed to be in place as soon as possible and that he was throwing his support behind Ignatieff. The next day Rae dropped out of the race and Ignatieff was acclaimed leader when Dion stepped down.

41st Canadian Parliament

LeBlanc retained his seat in the 2011 election, the only Liberal to be elected in New Brunswick, while the Liberals dropped down to third place in the House of Commons.

Following Ignatieff's resignation as leader, LeBlanc was seen as a potential leadership candidate. LeBlanc did not say whether he was considering a bid but hoped to be part of the "rebuilding and renewal" of the party. Later, LeBlanc said that the next leader needs to commit 10 to 15 years of his or her life "occupied exclusively" with rebuilding the Liberal party and winning elections. On October 5, 2012, he announced he would not stand for the leadership and instead endorsed Justin Trudeau.

From 2012 to 2015, LeBlanc served as the Liberal opposition house leader.

In government

42nd Canadian Parliament

Leader of the Government in the House of Commons

On November 4, 2015, he was appointed the leader of the Government in the House of Commons in the present Cabinet, headed by Justin Trudeau.

As Government House Leader, LeBlanc was an ex officio member of the Board of Internal Economy, a committee of Members of Parliament chaired by the Speaker of the House of Commons who oversees the internal affairs of the House of Commons. He had previously been a member of committee as the Liberal Party’s House Leader while in opposition from 2012 to 2015, and continued to serve on the Board until October 26, 2023.

During his tenure as House Leader, LeBlanc introduced Bill C-22, which created the National Security and Intelligence Committee of Parliamentarians, a committee composed of Members of Parliament and Senators equipped with top-secret security clearances and with a mandate to conduct oversight of the work of Canada’s national security and intelligence community. The committee is the first body of its kind in Canada, offering parliamentarians an unprecedented view into highly classified intelligence and activities conducted by the Canadian Security Intelligence Service (CSIS), the Communications Security Establishment (CSE), the Royal Canadian Mounted Police (RCMP) and Global Affairs Canada. It produces classified and unclassified reports which are shared with the Prime Minister. The classified version of the report is subsequently tabled in Parliament and released publicly.

Minister of Fisheries, Oceans and the Canadian Coast Guard

On May 31, 2016, upon the resignation of Hunter Tootoo from the Ministry, LeBlanc was named Minister of Fisheries, Oceans and the Canadian Coast Guard. His father had previously held the equivalent position under Prime Minister Pierre Trudeau. He retained the post of Government House Leader until August 19 of that year.

During his tenure as Minister of Fisheries and Oceans, LeBlanc modernized the Fisheries Act, strengthening the provisions contained in the legislation regarding the protection of fish stocks and fish habitat. He also introduced legislation amending the Oceans Act and the Canada Petroleum Resources Act to establish a national network of Marine Protected Areas, a novel type of conservation measure in Canada. Since then, 14 Oceans Act Marine Protected Areas (MPAs) have been established across Canada, comprising over 350,000 km² or roughly 6% of Canada’s marine and coastal areas, contributing to Canada’s goal of protecting 30% of its marine areas by 2030, in accordance with its international commitments.

LeBlanc’s tenure was also marked by heightened concerns regarding the entanglement of North Atlantic Right Whales, an endangered species, in fishing gear, leading to the death of several cetaceans. In response, LeBlanc engaged with industry groups, Indigenous communities and United States fishing authorities to develop new fishing gear and implement seasonal restrictions to maritime traffic to reduce the risk of entanglement and collisions.

On September 12, 2018, the ethics commissioner, Mario Dion, found LeBlanc broke conflict of interest rules when he awarded a lucrative Arctic surf clam licence to a company linked to his wife's cousin in February 2018.

LeBlanc was also a lead minister behind the Atlantic Growth Strategy, an intergovernmental forum comprising all four Atlantic premiers and all Atlantic federal ministers launched on July 4, 2016. The Strategy’s goal is to attract newcomers and investment to Atlantic Canada by enabling collaboration between the federal government and Atlantic provinces on immigration, innovation, clean technology, trade and investment, and infrastructure.

Minister of Intergovernmental Affairs, Northern Affairs and Internal Trade

On July 18, 2018, LeBlanc was shuffled from Minister of Fisheries, Oceans and the Canadian Coast Guard to Minister of Intergovernmental Affairs, Northern Affairs and Internal Trade He also became vice-chair of the Cabinet Committee on Agenda, Results and Communications, which is manages the government’s overall strategic agenda and priority setting, and tracks implementation, which is chaired by the Prime Minister.

As Minister of Northern Affairs, LeBlanc shepherded legislation amending the Mackenzie Valley Resource Management Act to give Indigenous communities in the Northwest Territories and the surrounding region a greater say in the management of resource development projects.

On the internal trade front, LeBlanc advanced several initiatives to make it easier to trade within Canada. He pushed provinces and territories to standardize provincial regulations in several key industries, including construction, food and drink, and manufacturing, reducing administrative burdens and making it easier for businesses to do business in other provinces. In December 2018, at a First Ministers’ Meeting in Montréal, LeBlanc led a discussion with Premiers on ways to strengthen internal trade in Canada.

On April 26, 2019, LeBlanc announced he would be stepping back from cabinet as he sought treatment for cancer.

43rd Canadian Parliament

President of the Queen’s Privy Council for Canada

On November 20, 2019, LeBlanc returned to Cabinet as President of the Queen's Privy Council for Canada, a position with reduced responsibilities. His former role as Minister of Intergovernmental Affairs, Northern Affairs and Internal Trade, was split between the minister of northern affairs, and the minister of intergovernmental affairs.

After the resignation of Bill Morneau as Minister of Finance, LeBlanc again became Minister of Intergovernmental Affairs after his successor, Chrystia Freeland, took the role of Minister of Finance in a cabinet shuffle on August 18, 2020. He retained his position as President of the Queen's Privy Council for Canada.

44th Canadian Parliament

Minister of Intergovernmental Affairs, Infrastructure and Communities

On October 26, 2021, LeBlanc was appointed Minister of Intergovernmental Affairs, Infrastructure and Communities, as well as chair of the Sub-Committee on Intergovernmental Coordination, which takes an intergovernmental lens to the key issues before the government. He continued to chair the Cabinet Committee on Operations and the Sub-Committee on the Federal Response to the Coronavirus Disease (COVID-19).

During his tenure, he oversaw the allocation of billions of dollars of investment through the Investing in Canada Infrastructure Program (ICIP) and reached deals with provinces and territories to accelerate the allocation of their respective ICIP funding envelopes ahead of the planned deadline. This was meant to boost public investment in job-creating projects during a time of economic uncertainty caused by the COVID-19 pandemic.

In addition, LeBlanc launched calls for applications under several funds, including the Green and Inclusive Community Buildings Program and the Disaster Mitigation and Adaption Fund. Both funds brought hundreds of millions of dollars in investment to communities across the country and helped them reduce their carbon footprint while becoming more resilient to the effects of climate change.

Throughout this time, LeBlanc also retained responsibilities for two previously-held files, Democratic Institutions and Internal Trade.

In his role as Minister responsible for Democratic Institutions, he oversaw the adoption of the Preserving Provincial Representation in the House of Commons Act in 2022, which amended the Constitution Act, 1867 to provide that a province may not have fewer Members of Parliament than it had during the 43rd Parliament. This was in response to riding boundary adjustments made following the 2021 decennial census, which would otherwise have seen Quebec lose a seat in the House of Commons.

In his role as Minister responsible for Internal Trade, in December 2022, he launched the Federal Action Plan to Strengthen Internal Trade, which led to the removal and narrowing of one third of all federal exceptions in the 2017 Canadian Free Trade Agreement.

In his role as Minister of Intergovernmental Affairs, LeBlanc worked with provincial and territorial Premiers to follow up on the February 2023 First Ministers’ Working Meeting on healthcare. All provinces and territories would eventually reach bilateral agreements on healthcare funding, which will see 198 billion dollars invested in healthcare over the ten-year life of the agreements.

Following the conclusion of a supply and confidence agreement between the Liberals and the New Democratic Party (NDP), Delivering for Canadians Now, the Prime Minister appointed LeBlanc to the oversight group struck to ensure that the commitments outlined in the agreement remained on track. LeBlanc would remain a member of the steering committee until the NDP put an end to the agreement in September 2024.

LeBlanc was also designated by the Prime Minister to be the lead minister on the Government of Canada’s response to the Public Order Emergency Commission (otherwise known as the Rouleau Commission), which was created following the invocation of the Emergencies Act by the Government of Canada to put an end to several illegal blockades in Ottawa and across the country in February 2022. He released the Government of Canada’s response to the Commission’s Final Report on March 6, 2024.

In November 2024, LeBlanc accompanied Prime Minister Trudeau for his meeting with U.S. President-elect Donald Trump at Mar-a-Lago.

Minister of Finance and Intergovernmental Affairs

On December 16, 2024, he was sworn in as the minister of finance following the surprise resignation of former finance minister and deputy prime minister Chrystia Freeland. LeBlanc was considered as a possible candidate in the 2025 Liberal Party of Canada leadership election, upon the resignation of Trudeau. He declined to run in the election, citing the need to focus on potential tariffs from the incoming second Trump administration.

45th Canadian Parliament

President of the King’s Privy Council for Canada and Minister responsible for Canada-U.S. Trade, Intergovernmental Affairs, Internal Trade and One Canadian Economy

On May 13, 2025, following the 2025 federal election, which was won by the incumbent Liberal Party, LeBlanc was appointed President of the King’s Privy Council for Canada and Minister responsible for Canada-U.S. Trade, Intergovernmental Affairs and One Canadian Economy. In addition to retaining responsibility for intergovernmental affairs, LeBlanc was tasked with establishing a new economic and security relationship with the United States. Since Prime Minister Trudeau’s visit to Mar-a-Lago in November 2024, LeBlanc had become a key interlocutor with the United States Commerce Secretary, Howard Lutnick, and accompanied Prime Minister Carney on his visit to Washington on May 6, 2025. He was also tasked with building one Canadian economy by removing barriers to interprovincial trade, and identifying and expediting nation-building projects.

During the post-election spring sitting of Parliament, LeBlanc was the lead minister on Bill C-5, the One Canadian Economy Act, which received Royal assent on June 26. Part two of the Act enacts the Building Canada Act, which institutes a process by which the federal Cabinet can designate certain projects as being in the national interest. Designation provides upfront approval for the project and expedites regulatory reviews so that the project benefits from a final regulatory decision within two years. The Act fulfilled a key pledge from the Liberal campaign, which centered around the need for Canada to become less reliant on the United States. The Liberals committed to building trade-enabling and energy infrastructure that would allow Canada to diversify its trade relationships away from the United States and bolster its internal market.

On September 16, 2025, LeBlanc added the role of Minister of Internal Trade to his portfolio following the resignation of Chrystia Freeland from cabinet.

Electoral record

Personal life

In 2003, he married Jolène Richard, a former Moncton lawyer who became a judge on the Provincial Court of New Brunswick in 2008, and eventually became a chief judge. She is the daughter of Guy A. Richard, who served as Chief Justice of the Court of Queen's Bench of New Brunswick. He has an adult stepson.

Cancer treatment

In December 2017, he announced that he had been diagnosed with chronic lymphocytic leukemia and would begin chemotherapy immediately while continuing to serve in his parliamentary roles. However, following a period of remission, his cancer took a turn for the worse. On April 26, 2019, LeBlanc announced he would be stepping back from cabinet as he sought treatment.

In September 2019, LeBlanc underwent a stem cell transplant at Maisonneuve-Rosemont Hospital in Montréal, Québec to cure his non-Hodgkin’s lymphoma, an extremely rare form of cancer. Following initial chemotherapy treatments at the CHU Dr. Georges L. Dumont Hospital in Moncton, New Brunswick, his doctors referred him to specialists at Maisonneuve-Rosemont Hospital due to the severity and aggressiveness of his cancer. He spent 56 nights, spanning most of the 2019 federal election campaign, in an isolation room at Maisonneuve-Rosemont.

He was sworn in as President of the Queen’s Privy Council in November 2019, two weeks after being discharged from the hospital, and returned to the House of Commons in late January 2020.

LeBlanc has talked publicly about his experience with cancer and his stem cell transplant. After the regular two-years non-contact time between donor and patient, in September 2022, he met with his stem cell donor, German national Jonathan Kehl. The meeting between the two was the subject of significant attention in Canadian media. LeBlanc also travelled to Germany to visit Kehl’s family in May 2023.
