Conservative MP Larry Brock, representing Brantford-Brant South-Six Nations, announced his resignation from Parliament effective September 18. Brock, who plans to return to his previous role at the Crown attorney’s office in Brantford, emphasized his ongoing commitment to community safety and justice in his resignation letter shared on social media. He served as the shadow justice minister until being replaced in June and has a long history in legal practice, having spent nearly 19 years as a prosecutor. Brock, first elected in 2021, succeeded long-serving MP Phil McColeman and was re-elected in 2025 with over 52% of the vote. His departure marks the seventh resignation from Conservative Leader Pierre Poilievre’s caucus since the 2025 election, prompting a byelection in his riding.
Why It Matters
Brock’s resignation contributes to a notable trend of instability within the Conservative Party, with several MPs leaving the caucus since the last election. This may impact the party’s ability to maintain its foothold in Brantford-Brant South-Six Nations, a riding that has leaned Conservative for nearly two decades. The upcoming byelection will be the eighth held in Ontario since August 31, indicating a broader shift in party dynamics and potential electoral challenges. Additionally, the Liberal Party currently enjoys a slight increase in seat count, following recent floor crossings and byelection wins, which may further influence the political landscape as the next general election approaches.
