Ontario Conservative MP Larry Brock is resigning as member of Parliament and is to return to his previous role as a prosecutor in southwestern Ontario.
Brock, the MP for Brantford-Brant South-Six Nations, said in a social media post Thursday he would officially resign his seat Sept. 18 to return to the “front lines of justice” at the Crown attorney’s office in Brantford, Ont.
First elected in 2021, Brock served as justice critic but was shuffled out of that position by Conservative Leader Pierre Poilievre in June.
His departure also leaves another vacancy for the Conservatives and triggers a byelection in the southwestern Ontario riding.
He is the seventh MP to leave Poilievre’s caucus since the 2025 election, with four of them crossing the floor to the Liberals.
“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,” he said in his social media post.
He said he was honoured to serve as justice critic, “given my commitment to reforming the criminal justice system, holding criminals accountable and restoring trust and confidence in our legal system.”
In a social media post Thursday, Poilievre thanked Brock for “fighting to end liberal bail reform, for putting criminals behind bars, for restoring safety to our streets, and for supporting victims.”

Brock was a prosecutor for almost 19 years before running for federal politics.
He has been a prominent Conservative voice arguing that Liberal crime and justice measures do not go far enough. In September 2025, Brock said the Liberals’ promised bail reform legislation should adopt the provisions of the “jail not bail act” from the Conservatives.
The Opposition party proposed measures to make it harder for people to receive bail if they have been arrested for or charged with a violent offence in the previous 10 years.
The riding of Brantford-Brant South-Six Nations has been Conservative since 2008, when Liberal incumbent Lloyd St. Amand lost the seat to Conservative Phil McColeman.
“I have full confidence that the team will keep delivering for this community for the years to come with the soon-to-be next Conservative MP for Brantford-Brant South,” Brock said.

Kerplunk. There goes another rat jumping over to another ship.
Another one bites the dust.
Tragic, he will be missed.
This is a safe Conservative seat as the Brampton folks didn’t buy into Carneys Elbows Up drivel. Brock is leaving as to pass the torch for the next GE.
@Marylin G – Heard you are polling 3rd in your riding in Sarnia. What is your plan come next election.
He is going to a different job. a lot of pea brain liberals on here.
@Anonymous. LPC nationally has slipped already 6-8 points. Carneys lack of results is a problem. He made huge promises and hasn’t delivered FYI not a conservative either just tellling you the truth.
A dictionary is a literary reference guide. It describes how words are being used. It does not actually define the word. When you fail to understand the context of the word and how it is being used then you are in no position to say that right wing fringe commentors are teaching liberals anything at all.
Carney’s leadership is not being questioned. Poilievre’s is. His grip on the conservative party is weak due to his leadership style.
@Biny. How many Libs have left, could it be Carneys leadership? Freeland, Smith, Wilkinson, Blair, Guilbeault, etc
@Webster Basics.
Read a dictionary. The term traitor is defined as “one who betrays another’s trust or is false to an obligation or duty.”
Why do Conservatives have to teach Liberals everything ?
Another day, another MP leaving the Poilievre conservatives. How many does Poilievre have left? Could it be…could it be… his leadership? Of course Poilievre’s loyal mini maga base won’t admit that.
Sorry. How many Liberals have left again? Sounds like Brock wants to go back into real work.
One can almost feel sorry about the snarky Poilievre but then reality hits. The conservatives have had meetings with the Trump administration undermining our foreign policy so no, have no empathy for the security clearance lacking Poilievre.
Stop the quitting.
Dan Singh, and other conservatives here: let’s get one thing corrected; the term “traitor” is reserved for those who sell out their country to a foreign power, not for lacking the blind loyalty to stay on a sinking ship. Floor crossing is a parliamentary function, centuries old, and at times cheered by the conservatives (when benefitting them). You want your party to stop bleeding? Get a leader that isn’t a lickspittle to a hostile foreign nation. Calling people running from that mess a “traitor” is very, very telling. Conservatives need to adjust their sense of loyalty before anyone can say “loyal opposition” with a straight face.
When Lethbridge Liberace finally steps down, the party can heal and start again. At this point it’s embarrassing to support the Conservative fiasco.
Weak leadership from Poilievre. No wonder he’s still 18% in the polls.
This criminal should be in jail, and this ‘news’ network should be closed down
Regardless of your party. If you go through all that time and money as an MP you need to serve your term. What’s the point of running if you’re not going to fulfill your duties,
All seven who left thought PP was a twit.
They weren’t wrong.
PP took his job from him.
Way to go Whinestone Cowboy.
And to think PP once had a 28 point lead on the Libbys.
Then he started whining from our mansion.
LOL
Another great job by PP.
What an utter embarrassment.
At least Brock goes with some dignity unlike the floor crosses who should have resigned instead of taking some form of incentive to cross the floor. Traitors
Poilievre showing the country the benefits of a dominant leader.
Poilievre loses another MP. This seems to be a regular occurrence.
The mispronunciation of Chicoutimi was hilarious!
The 12 federal by-elections held since 2022 have cost taxpayers an estimated total of $21 million, or an average of more than $1.75 million each, according to Elections Canada data.
This guy committed to a role that he should serve until October 15, 2029.
