Conservative MP Larry Brock announced Thursday night he will be stepping down as a member of Parliament next month.
“When I first thought about my time in political public service, my plan was to keep representing the hardworking people of Brantford-Brant South for years to come,” Brock said in a post on X. “Following careful consideration, I’ve decided to step down as a member of Parliament.”
Brock, a prominent law-and-order advocate, said he will officially resign his seat on Sept. 18 and return to his former position with the Brantford Crown attorney’s office.
His resignation will trigger a byelection in the Ontario riding.
Brock was first elected to Parliament in 2021, replacing longtime Conservative MP Phil McColeman, and was re-elected in 2025 with more than 52 per cent of the vote share.
He previously served as the Conservative justice critic but was replaced in June by Ontario MP Arpan Khanna.
Another Conservative MP leaves caucus
In a statement on X, Conservative Leader Pierre Poilievre thanked Brock “for fighting to end Liberal bail, to lock up criminals, to restore safe streets and to support victims.”
Brock will become the seventh MP to leave Poilievre’s caucus since the 2025 federal election.
Chris d’Entremont, Michael Ma, Matt Jeneroux and Marilyn Gladu crossed the floor to join the Liberals, while Cathy Wagantall said she would resign at the end of August. Richard Martel was appointed to the Senate by Prime Minister Mark Carney in July.
The Liberals formed a minority government through the 2025 election, but the combination of floor-crossings and a trio of byelection victories last April helped Carney secure a majority.
