Conservative Member of Parliament Larry Brock has announced his decision to step down from the House of Commons next month. Representing the Ontario constituency of Brantford—Brant South—Six Nations, Brock was elected to Parliament in both the 2021 and 2025 federal elections. Before his political career, he worked as an assistant Crown attorney.
In a social media post on Thursday, Brock revealed that he has accepted a position to return to work at the Brantford Crown Attorney’s office. His resignation will become effective on September 18, according to the letter he shared.
Conservative Leader Pierre Poilievre expressed gratitude to Brock for his service as an MP in a brief message on a social media platform. Poilievre wished Brock and his family success and happiness, concluding with a heartfelt message.
Following the 2025 federal election, where the Conservatives secured the second-highest number of seats, the party has witnessed the departure of seven MPs, including Brock, from its federal caucus. Four Conservative MPs switched sides to join the governing Liberals: Chris d’Entremont, Michael Ma, Matt Jeneroux, and Marilyn Gladu. Additionally, Richard Martel, the former MP for Chicoutimi—Le Fjord in Quebec, was appointed to the Senate by Prime Minister Mark Carney in July.
Cathay Wagantall, a Conservative MP since 2015, will be stepping down from her seat of Yorkton—Melville in Saskatchewan effective August 31.
