Conservative Member of Parliament Larry Brock has announced his upcoming resignation from the House of Commons next month. Representing the Ontario constituency of Brantford—Brant South—Six Nations, Brock secured his parliamentary seat in both the 2021 and 2025 elections. Prior to his tenure in Parliament, he served as an assistant Crown attorney.
In a social media post on Thursday, Brock revealed that he had accepted a new position at the Brantford Crown Attorney’s office, prompting his decision to step down. His resignation is scheduled to take effect on September 18, as stated in the official announcement.
Following the news, Conservative Leader Pierre Poilievre shared a brief message on X, expressing gratitude to Brock for his contributions as an MP. Poilievre conveyed his well wishes for Brock and his family, emphasizing his hopes for their future success and happiness.
Although the Conservative Party secured the second-highest number of seats in the 2025 federal election, it has experienced the departure of seven MPs from its federal caucus, including Brock. Notably, four Conservative MPs crossed the floor to join the governing Liberals: Chris d’Entremont, Michael Ma, Matt Jeneroux, and Marilyn Gladu.
In related developments, former MP Richard Martel from the Quebec riding of Chicoutimi—Le Fjord was recently appointed to the Senate by Prime Minister Mark Carney. Additionally, Cathay Wagantall, a Conservative MP since 2015, is set to resign from her seat in Yorkton—Melville, Saskatchewan, effective August 31.
