Lindsay Mathyssen is a Canadian politician who served as the member of Parliament for the riding of London—Fanshawe in the House of Commons of Canada from 2019 to 2025 as a member of the New Democratic Party (NDP). She is the daughter of Irene Mathyssen, whom she succeeded in office.
Background
Mathyssen graduated from Medway High School and earned a bachelor's degree in English and political science from Queen's University in 2001. She later studied non-profit management at the University of Western Ontario.
Before entering federal politics, Mathyssen held clerical positions with several private-sector employers, including London Life and Staples. In 2002, she began working with the New Democratic Party (NDP) in various capacities and, over 11 years, she served as an NDP staffer to four different members of Parliament.
Political career
Mathyssen was acclaimed as the NDP candidate for the riding of London—Fanshawe on November 4, 2018, succeeding her mother, Irene Mathyssen, who had represented the riding since 2006. Prior to this, Mathyssen had sought the NDP nomination in the neighbouring riding of London North Centre ahead of the 2015 federal election but was defeated by German Gutierrez.
In the 2019 federal election, Mathyssen was elected member of Parliament for London—Fanshawe. She was re-elected in the 2021 election. During her time in office, Mathyssen held various parliamentary roles, including Deputy House Leader of the NDP.
Her tenure ended in the 2025 federal election, when she was defeated by Conservative candidate Kurt Holman, bringing an end to the Mathyssen family's 19-year representation of the riding.
