Joseph Jean-Pierre Marc Garneau (French pronunciation: [maʁk ɡaʁno]; February 23, 1949 – June 4, 2025) was a Canadian Armed Forces officer, astronaut and politician. Garneau served as a naval officer before being selected as an astronaut as part of the 1983 NRC Group. He became the first Canadian in space on October 5, 1984, and flew on three Space Shuttle missions. From 2001 to 2005, Garneau was president of the Canadian Space Agency (CSA). Garneau entered politics and was elected to the House of Commons in 2008, serving as a Montreal-area member of Parliament (MP) until 2023. A member of the Liberal Party, Garneau served as Minister of Foreign Affairs from January to October in 2021 and as Minister of Transport from 2015 to 2021.
Born in Quebec City, Garneau joined the Canadian Armed Forces, graduating with a bachelor's degree in engineering physics from the Royal Military College of Canada in 1970, and serving with Maritime Command (now known as the Royal Canadian Navy) as a combat systems engineer. He earned a PhD in electrical engineering from the Imperial College of Science and Technology in 1973. In 1983, Garneau was selected to be an astronaut. In 1984, he became the first Canadian in space as part of STS-41-G and served on two subsequent missions: STS-77 and STS-97. He was appointed executive vice-president of the CSA in February 2001, before becoming the agency's president in November. Garneau resigned from the CSA in 2005, and was elected to Parliament in 2008. The Liberal Party formed government following the 2015 election and Garneau was appointed to Cabinet. After serving as transport minister and foreign affairs minister, Prime Minister Justin Trudeau did not appoint Garneau to another portfolio after a Cabinet shuffle following the 2021 election. In 2023, Garneau retired from politics.
Joseph Jean-Pierre Marc Garneau was born into a military family on February 23, 1949, in Quebec City, Quebec, Canada. His grandfather, Gérard Garneau, was a colonel who served in the Canadian military during World War I. His father, André Garneau, was a French Canadian from Quebec City who joined the military during World War II. His mother, Jean Richardson, was English Canadian from Sussex, New Brunswick, and was a nurse during World War II. She met André while nursing him at a military hospital before he deployed overseas. After the war, André continued his service in the Canadian military, rising through the ranks to become a brigadier general. The Garneau family had four sons, beginning with Braun, followed by Marc, Charles, and Philippe Garneau.
Garneau's frequent relocations due to his father's occupation during his upbringing necessitated his attendance at various schools, spanning both primary and secondary education, in Quebec City, Saint-Jean-sur-Richelieu and London, England. He graduated from the Royal Military College of Canada in 1970 with a bachelor of science in engineering physics and began his career in the Canadian Forces Maritime Command.
In 1973, he received a PhD in electrical engineering from the Imperial College of Science and Technology in London, England. His thesis was titled "The Perception of Facial Images". The Photofit analogue computer was used by him to discriminate facial features. In 1974, Garneau served as a naval combat systems engineer aboard HMCS Algonquin.
From 1982 to 1983, he attended the Canadian Forces Command and Staff College in Toronto. While there, he was promoted to the rank of commander and was transferred to Ottawa in 1983. In January 1986, he was promoted to captain. Garneau retired from the Canadian Forces in 1989.
On December 5, 1983, the National Research Council of Canada (NRC) announced Canada's first group of astronauts that were to fly on NASA's Space Transportation System. Garneau joined this first Canadian Astronaut Program (CAP) group, as one of six chosen from over 4,300 applicants. Of these six original astronauts, he was the only military officer. Garneau became the first Canadian to reach space on October 5, 1984, when Space Shuttle Challenger flew into low Earth orbit.
Garneau's first spaceflight was aboard the Space Shuttle Challenger, on the STS-41-G mission, from October 5 to 13, 1984. He was a payload specialist. He was promoted to the rank of Navy Captain in 1986, and left the Canadian Forces in 1989, to become deputy director of the CAP. In 1992–93, he underwent further training to become a mission specialist. He worked as CAPCOM for a number of shuttle flights and was on two further flights himself: STS-77 (May 19 to 29, 1996) and STS-97 (to the ISS, November 30 to December 11, 2000). He logged 677 hours in space.
On February 1, 2001, Garneau was appointed executive vice-president of the Canadian Space Agency (CSA). On September 28, 2001, the government announced his appointment as president of the CSA, replacing Mac Evans in that position on November 22, 2001. Garneau resigned from the Canadian Space Agency on November 28, 2005.
Garneau served as the Member of Parliament (MP) in the Canadian House of Commons for over 14 years. He represented two electoral districts during this time, first Westmount—Ville-Marie, and after the 2012 Canadian federal electoral redistribution, Notre-Dame-de-Grâce—Westmount. His first attempt to win elected office was unsuccessful, as he placed second in the Vaudreuil—Soulanges electoral district during the 2006 federal election. He first won elected office as a result of the 2008 federal election, winning his seat by over 9,000 votes. He was re-elected to the House of Commons in the 2011 federal election by 642 votes. His electoral district was abolished and he stood for office in the newly created Notre-Dame-de-Grâce—Westmount district for the 2015 federal election. He won the election with a majority of over 18,000.
On November 28, 2012, Garneau announced his candidacy for the leadership of the Liberal Party to be decided in April 2013. On March 13, 2013, Garneau formally withdrew his bid for the party leadership. On November 4, 2015, Garneau was appointed Minister of Transport in the 29th Canadian Ministry of Prime Minister Justin Trudeau. He became Minister of Foreign Affairs on January 12, 2021, after a cabinet reshuffle.
Garneau resigned as the president of the Canadian Space Agency to run for the Liberal Party of Canada in the 2006 federal election in the riding of Vaudreuil—Soulanges, which was then held by Meili Faille of the Bloc Québécois. The Liberal Party's support dropped off considerably in Quebec after the Sponsorship scandal and though considered a star candidate, Garneau lost to Faille by over 9,000 votes.
In the 2006 Liberal Party leadership election Garneau announced his support for perceived front-runner Michael Ignatieff, who lost to Stéphane Dion on the final ballot. With the resignation of Liberal MP Jean Lapierre in 2007, Garneau expressed interest in being the party's candidate in Lapierre's former riding of Outremont. Dion instead appointed Jocelyn Coulon as the party's candidate, who went on to be defeated by the New Democratic Party's Thomas Mulcair in the by-election.
In May 2007, Garneau filed nomination papers to be the party's candidate in Westmount—Ville-Marie, after former Liberal Party deputy leader Lucienne Robillard announced she would not be seeking re-election. However, a week after filing his nomination papers Dion announced that he had hand-picked a candidate for the riding. Garneau later withdrew his nomination papers and announced he no longer had an interest in politics. In October 2007, Garneau and Dion held a joint news conference where they announced that Garneau would be the Liberal Party candidate in Westmount—Ville-Marie. Robillard announced her resignation as Member of Parliament in January and a by-election was later scheduled for September 8, 2008. However, the by-election was cancelled during the campaign when Prime Minister Stephen Harper called a general election for October 14, 2008. Though some pundits predicted a close race between Garneau and NDP candidate Anne Lagacé-Dowson, Garneau went on to win the riding by over 9,000 votes.
