Reason for Byelection Loss of previous seat

Did Pierre Poilievre lose his seat?

Yes. On April 28, 2025, Pierre Poilievre lost the Carleton riding to Liberal candidate Bruce Fanjoy, who received 43,846 votes (50.95%) against Poilievre’s 39,333 votes (45.70%). Fanjoy defeated the Conservative leader by over 4,300 votes, an upset that ended Poilievre’s streak of seven straight wins since 2004.

The implication: Poilievre became the first major party leader in decades to lose his own riding in a general election. It forced an immediate recalculation of his political future.

Why was the byelection necessary?

Under Canadian law, a person cannot sit in Parliament without representing a riding. After losing Carleton, Poilievre had to secure a seat in a different riding to remain leader of the Conservative Party and serve as an MP. The party arranged a byelection in Battle River-Crowfoot, Alberta—a safe Conservative seat—which he won in August 2025 with about 80% of the vote.

  • Loss of seat triggers leadership review? No, but it requires a new seat.
  • Byelection held in a riding vacated by a retiring Conservative MP.

What were Pierre Poilievre’s vote percentages?

In the 2021 federal election, Poilievre won Carleton with 35,356 votes (49.89%), down from 50% in the same riding in 2021. By 2025, his share dropped to 45.70%, a decrease of 6.15 percentage points. In the August 2025 byelection, he rebounded dramatically with 80% of the vote in Battle River-Crowfoot.

The pattern: Poilievre’s vote share in his long-held Ottawa-area riding eroded over time, while he received a mega-majority in a new Alberta riding—highlighting regional differences in Conservative support.

2021 Carleton election result

In 2021, Poilievre secured 49.89% of the vote, ahead of Liberal candidate Michelle Corpuz (30.80%) and NDP candidate Kevin Hua (12.36%).

What this means: Even in his strongest showing in Carleton, Poilievre never broke 55% in a riding that was considered a safe Conservative seat.

2025 byelection vote share

In the Battle River-Crowfoot byelection, Poilievre took 80% of the vote—a commanding margin that reflects the deep Conservative base in rural Alberta. The Liberal candidate received fewer than 15% of the ballots.

The trade-off: While the byelection win secured his seat, it also moved his representation to a different province, altering his political roots.

Which riding did Pierre Poilievre win in the byelection?

He won Battle River-Crowfoot, a riding in east-central Alberta. The byelection was held in August 2025 after the sitting Conservative MP resigned to make way for the party leader.

Why this matters: Poilievre now represents Albertans rather than Ontarians—a shift that could affect his voter base and regional focus in the next election.

Battle River-Crowfoot in Alberta

The riding is predominantly rural, spanning from the Saskatchewan border to the eastern slopes of the Rockies. It is one of the safest Conservative seats in Canada, having elected Conservative MPs by large margins since its creation.

  • First elected as MP for Carleton at age 25 in 2004.
  • Held Carleton continuously until April 28, 2025.

What is Pierre Poilievre’s original riding?

His original riding is Carleton, located in Ontario’s Ottawa region. He represented it from 2004 until his defeat in 2025.

The catch: Carleton was more competitive than many assumed—Fanjoy’s victory margin (4.5 percentage points) was modest but historic.

History of Carleton riding

Carleton was created in 2003 from parts of Nepean—Carleton and Lanark—Carleton. Poilievre won the first election in 2004 with 44.6% of the vote and held it through seven victories.

Why this matters: The riding’s demographic shift—more urban and younger—likely contributed to the 2025 upset.

Historic first: Poilievre became the first major party leader to lose his own seat in a general election since 1993.

Seat shift: Poilievre’s move from Ontario to Alberta may affect his voter base and regional focus in the next general election.

For the Conservative leader, the 2025 election cycle delivered both a humbling loss and a swift, if unconventional, comeback. The margin in Carleton—over 4,300 votes—signals that even a prominent leader cannot take a seat for granted. The byelection win gave him a second start, but in a different province. For Poilievre’s future, the choice is clear: consolidate his new Albertan base while rebuilding support in his home region, or face a similar challenge in the next general election.
