Brantford — Conservative MP Larry Brock announced he will resign his seat in the House of Commons effective Sept. 18 to return to work with the Brantford Crown Attorney’s office, leaving constituents in Brantford—Brant South—Six Nations without federal representation heading into the autumn.
Local lawyer returns to frontline justice
Brock, who was first elected in 2021 and re-elected in 2025, said in a social media post and accompanying letter that he has accepted an opportunity to resume duties at the local Crown attorney’s office. Before entering federal politics, he had worked as an assistant Crown attorney.
The decision ends a parliamentary term during which Brock represented a riding that includes the city of Brantford and surrounding communities. His resignation will trigger a vacancy that could lead to a by-election, though the federal government has discretion on the timing.
Party reaction and broader context
Conservative Leader Pierre Poilievre acknowledged Brock’s departure on the social platform X, offering his personal wishes.
“My ardent wish is for you and your family to have all the success and happiness in the world. God bless, my friend.”
Brock’s exit is the latest in a string of departures from the Conservative benches since the 2025 federal election. Several MPs previously left the caucus for a mix of reasons including floor crossings and appointments.
- Four MPs crossed the floor to join the governing Liberals: Chris d’Entremont, Michael Ma, Matt Jeneroux and Marilyn Gladu.
- Richard Martel left his seat after being appointed to the Senate.
Those moves, together with Brock’s resignation, bring the number of Conservative MPs to leave the party’s federal caucus since the 2025 election to seven, a trend that has drawn attention from political observers and local constituents alike.
What this means for Brantford residents
When a seat in the House of Commons becomes vacant, residents temporarily lack direct parliamentary representation. Constituents can still contact the local MP’s office until the resignation date, and constituency services typically continue to operate for a transition period.
A by-election may be called to fill the vacancy. Federal rules set a maximum window for how soon a by-election must be held after a seat becomes vacant, but the government may schedule it at its discretion within that period. Until a new MP is elected, parliamentary votes and constituency advocacy will not include a locally elected representative.
Background on Brock’s tenure
Larry Brock served two consecutive terms after winning in 2021 and again in 2025. His professional background as an assistant Crown attorney preceded his federal service and is the role he has chosen to return to in Brantford. The move underscores a return to front-line legal work rather than continued service in Ottawa.
| MP | Change |
|---|---|
| Larry Brock | Resignation (effective Sept. 18) — returning to Brantford Crown Attorney’s office |
| Chris d’Entremont | Crossed to Liberals |
| Michael Ma | Crossed to Liberals |
| Matt Jeneroux | Crossed to Liberals |
| Marilyn Gladu | Crossed to Liberals |
| Richard Martel | Appointed to the Senate |
Names listed above are those publicly reported to have left the Conservative benches since 2025. The reasons for each departure vary, and some involved acceptance of new roles outside the House of Commons.
Next steps for the riding
Local political groups and parties will likely begin preparations for a potential by-election, organising nominations and outreach in the coming weeks. Residents with ongoing casework handled by Brock’s office are advised to contact the constituency office for information on transitioning files.
For many in Brantford, the immediate impact will be practical: ensuring continuity of constituent services and clarity over when and how a replacement will be chosen. The broader political implications — including shifts in party dynamics and local campaign activity — will become clearer as the resignation date approaches and parties respond.
Further details on the timing of a by-election, if one is called, will be released by Elections Canada and the federal government in due course.
