Mark Gerretsen (born June 5, 1975) is a Canadian politician who is the Member of Parliament for Kingston and the Islands as a member of the Liberal Party of Canada. He was first elected in the 2015 federal election, and re-elected in 2019, 2021 and 2025. He currently serves as the Chief Government Whip.

Previously, he has served as Deputy Leader of the government in the House of Commons and well as the Parliamentary Secretary to the Leader of the Government in the House of Commons (Senate).

Early life and career Gerretsen was born in Kingston, Ontario, the son of Assunta (Garofalo) and John Gerretsen. His father was mayor of Kingston and a MPP for Kingston and the Islands, and held several positions in the cabinets of Premier Dalton McGuinty and Kathleen Wynne. His father was born in Hilversum, Netherlands, and his mother emigrated from San Bartolomeo in Galdo (Benevento) Italy to Kingston in 1956.

Mark graduated from Regiopolis Notre-Dame in 1993. Gerretson then launched a DJ business, performing at events like the Regiopolis Notre-Dame pep rally. He eventually transitioned to DJing at Stages Night Club in Kingston, Ontario. Gerretsen holds a bachelor's degree in economics from Queen's University and studied computers at St. Lawrence College. Gerretsen was first elected to Kingston City Council in 2006, where he represented the Portsmouth District. After completing his four-year term as City Councillor, Gerretsen served as Mayor of Kingston from 2010 to 2014.

Municipal politics As Mayor, Gerretsen worked alongside the City of Kingston and municipal leaders across Ontario, advancing issues such as payments in lieu of taxes, the integration of social services, and increased investment in local infrastructure and affordable housing. Gerretsen also oversaw the creation of the Mayor's Task Force on Development to improve customer service for residents, and the development of an Age-Friendly Plan focused on making Kingston more senior-friendly.

In 2012, Gerretsen was elected to represent the City of Kingston on the Association of Municipalities of Ontario (AMO) Board of Directors. As a member of the Large Urban Mayor's Caucus of Ontario (LUMCO), Gerretsen worked with municipal leaders across Ontario advocating for increased investments in local infrastructure and affordable housing.

Gerretsen gained some notoriety in 2013 when he voiced his displeasure regarding the street partying that occurs during Queen's University's Homecoming. The event had taken a five-year hiatus due to rowdy behaviour and significant costs to the municipality for policing and clean up, and Gerretsen had reservations about the event's return. Gerretsen visited Aberdeen Street that weekend to assess the situation. He tweeted directly to Queen's Principal Daniel Woolf: “I am standing at William and Aberdeen. I have two words for you: NOT GOOD”. The “NOT GOOD” phrase was, in turn, used by Queen's University students and publicized in a number of memes at the Mayor's expense.

Federal politics Gerretsen was first elected as a Member of Parliament in the 2015 federal election, replacing first-term Liberal MP Ted Hsu, who chose not to seek re-election. Gerretsen defeated Conservative candidate Andy Brooke by over 21,000 votes and earned 55.37% of the ballots cast.

In his first term in federal office, Gerretsen served on the Standing Committee for National Defence, and was elected as Chair of the Ontario Liberal Caucus. Gerretsen was also a member of the Standing Committee on the Environment and Sustainable Development for two and a half years.

Throughout 2015–2019, Gerretsen was able to obtain federal funding for many initiatives in Kingston and the Islands. Some of these investments included $1 million for Breakwater Park and Gord Downie Pier, $42 million for public transit, $31 million for new ferry vessels and $60 million for the Third Crossing.

Gerretsen's Private Members Bill, Bill C-243, The National Maternity Assistance Program Strategy, aimed to introduce amendments to the Employment Insurance Act to create a national maternity assistance program for women who are unable to work during their pregnancy and was based on the first-hand experience of a constituent in his riding. Gerretsen's Private Members Bill was introduced to the House of Commons on February 26, 2016. After passing second and third reading in Parliament, on October 26 and June 14, 2017, respectively, Gerretsen's Private Members Bill was brought to the Senate for first reading on June 14, 2017. When Parliament dissolved in the summer of 2019, Bill C-243 was at the Senate for third reading.

Gerretsen supports many Liberal policies, but sometimes voices his concerns with the direction the government takes on various files. As a strong environmental proponent, Gerretsen openly spoke against the Government's decision to expand the Kinder Morgan pipeline. In June 2018, Mark was one of three Liberal MPs who voted in favour of a motion proposed by the New Democratic Party to stop the project.

In 2019, 2021, and 2025 Gerretsen was re-elected as Member of Parliament. Currently, Gerretsen is Chief Government Whip. Previously, he has served as Deputy Leader of the government in the House of Commons and well as the Parliamentary Secretary to the Leader of the Government in the House of Commons (Senate).
