The Conservative Party's former justice critic has announced that he is stepping away from politics. Ontario Member of Parliament Larry Brock said he will be resigning his seat next month and returning to his former role as a prosecutor, closing out a stint in federal politics to head back to the courtroom where he built his earlier career.
Brock made the announcement in a letter posted to social media last night. In it, he said his commitment to community safety has not wavered, framing his exit as a return to familiar ground rather than a retreat, and arguing that getting back into the courtroom means he can continue to stay tough on crime, the issue that had defined much of his work in Parliament.
The resignation lands as another blow to the Conservative backbench. Brock is now the seventh Member of Parliament to leave the party since the 2025 election, a steady trickle of departures that has chipped away at the caucus Pierre Poilievre leads and drawn attention to the churn within Conservative ranks.
What makes the pattern especially pointed for the party is where some of those members have gone. Of the seven MPs who have left since the last election, four crossed the floor to join the Liberal Party, handing the governing side a series of symbolic wins as they walked away from the Conservative benches to sit with their rivals.
Brock's decision also carries an immediate practical consequence, as the vacancy he leaves behind triggers a by-election. The contest will be held in the Ontario riding of Brantford-Brant South-Six Nations, giving voters there a fresh campaign to fill the seat and offering an early test of the parties' standing in the region.
Conservative Leader Pierre Poilievre responded to the news on social media, taking the moment to wish Brock well as he moves on. Poilievre thanked the departing MP for his work on crime issues during his time in office and for his service to the people of his riding, marking the end of Brock's tenure on a note of gratitude despite the loss to the caucus.
