Conservative MP Larry Brock will resign his Brantford-Brant South seat next month, ending a five-year run in federal politics and returning to the courtroom as a Crown attorney.

Brock announced Thursday, Aug. 6, that his resignation will take effect Sept. 18, saying he has accepted an opportunity to return to the Brantford Crown Attorney’s office.

“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 statement. “Following careful consideration, I've decided to step down as Member of Parliament effective September 18, 2026.”

The announcement comes just over a month after Brock stepped back from his role as Conservative shadow minister of justice and attorney general.

On June 30, Brock said he was leaving the shadow cabinet for personal reasons, describing his time in the role as “an honour and a privilege.”

His departure from Parliament will mark a return to a profession Brock knew well before entering federal politics. He spent about two decades as a Crown prosecutor before being elected to the House of Commons in 2021.

“I've accepted an opportunity to return directly to the frontlines of justice at the Brantford Crown Attorney's office,” Brock said in Thursday’s statement. “My commitment to community safety hasn't wavered one bit, and getting back into the courtroom means I can keep being tough on crime, making sure real justice happens right here at home.”

Brock was first elected in September 2021 in the former Brantford-Brant riding and was re-elected in April 2025 following changes to the federal electoral boundaries. The House of Commons lists him as having been elected in 2021 and re-elected in 2025. 

In the 2025 federal election, Brock won the newly configured Brantford-Brant South-Six Nations riding with 34,501 votes, or 52.4 per cent of valid ballots. Liberal candidate Joy O'Donnell finished second with 27,032 votes, or 41.1 per cent. 

During his time in Ottawa, Brock became particularly associated with justice issues, using his background as a prosecutor to advocate for victims' rights, changes to Canada's bail system and broader criminal justice reforms.

In his resignation statement, Brock said his local Conservative team remains “as strong and united as ever” and expressed confidence in whoever succeeds him as the riding's Conservative representative.

Neighbouring Conservative MP Dan Muys, who represents Flamborough-Glanbrook-Brant North, said Brock's departure will be felt both locally and in Ottawa.

“Larry Brock will be missed by MPs from both sides of the aisle for his knowledge, expertise, good humour, kind nature and outspoken passion for all things Brantford-Brant,” Muys said in an email to the Paris Independent.

Muys credited Brock's advocacy on bail reform, victims' rights and the justice system, as well as his leadership as chair of the Conservative Ontario caucus for the past 14 months.

“Larry’s leadership shined through and was sought-after — not only for his unmatched understanding of the justice system, but also his work chairing the Ontario Caucus for the past 14 months,” Muys said.

He also pointed to the less-visible personal demands of political life, saying Brock and his family had “sacrificed much for the greater good and never expected the limelight.”

“All of our best wishes to Larry and his family on this new chapter in their lives,” Muys said.

Brock similarly used his statement to thank his staff in Ottawa and Brantford, Conservative Leader Pierre Poilievre and his caucus colleagues, as well as his wife, Angela, and daughters Jennie and Emma.

“The trust this community placed in me throughout my time in office is something I'll carry forever,” Brock said.

He closed his statement by describing representing the community as “the honour of a lifetime.”

Brock's resignation will leave the Brantford-Brant South-Six Nations seat vacant after Sept. 18 and ultimately require a federal byelection to select his successor.
