Conservative Member of Parliament Larry Brock has announced his resignation from the Ontario riding of Brantford-Brant South-Six Nations to return to his previous career as a Crown prosecutor. Brock confirmed his decision in a statement on social media late Thursday evening, following earlier reports of his impending departure.
Brock, first elected in 2021, had served as the party’s justice critic before being removed from the role in June during a cabinet shuffle by Conservative Leader Pierre Poilievre. At that time, Brock cited personal reasons for stepping aside but reaffirmed his support for Poilievre and the Conservative agenda, emphasizing his commitment to his constituents and broader goals such as public safety and affordable living.
In response to Brock’s resignation, Poilievre expressed gratitude for his colleague’s work, highlighting Brock’s efforts to reform the bail system, enhance public safety, and support victims. Poilievre also extended his well wishes for Brock’s future both personally and professionally.
Brock won his riding with 52 percent of the vote in the most recent election, marking a significant shift from the 2021 election when the vote was more evenly distributed among the Conservatives, Liberals, and the New Democratic Party. Recent polling data suggests the riding currently leans Conservative.
Brock’s departure marks the seventh resignation from Poilievre’s caucus since the 2025 federal election, a period marked by internal dissent and challenges for the party including poor polling results and fundraising struggles. Four former Conservative MPs have crossed the floor to join the Liberals. Among others who left the caucus, Saskatchewan MP Cathay Wagantall announced she would step down before the end of her term, and Quebec MP Richard Martel was appointed to the Senate by Prime Minister Mark Carney. A by-election for Martel’s former riding of Chicoutimi-Le Fjord is scheduled for late August.
During a recent visit to the area, Prime Minister Carney commented on the Liberals’ choice of candidate Daniel Gobeil, a former dairy producer, for the upcoming by-election. Carney described the selection as reflective of the government’s loyalty to Canada’s supply management system, a policy that the United States has identified as a point of contention in trade discussions. Conservative Leader Poilievre also visited the region earlier this week ahead of the by-election.
