John Ivison: Byelections are bedevilling Pierre Poilievre
- Since the 2025 general election where Conservatives won 41.31% of the vote, their support in seven subsequent byelections has dropped to an average of 24.6%, despite leader Pierre Poilievre’s strong win in one riding.
- The Liberals have been gaining ground, winning over 50% of the vote in three recent byelections, including former Conservative strongholds, highlighting growing public support for Prime Minister Mark Carney’s government amid national unity concerns.
- Poilievre’s stance on the Canada-U.S. trade dispute has shifted from a more accommodating tone to a tougher, critical approach against the government’s concessions, but this hardline position has not translated into increased voter support.
- The upcoming byelection in Brantford-Brant South—Six Nations, a historically safe Conservative seat, is seen as a critical test for Poilievre’s leadership and the party’s future, with potential significant consequences if the seat is lost.
In the 2025 general election, the Conservatives won 41.31 per cent of the vote. In the seven byelections since then, the party has averaged just 24.6 per cent support — and that includes leader Pierre Poilievre’s whopping 80.86 per cent win in Battle River—Crowfoot.
Politicians can dismiss polls as being a snapshot in time. The Conservative leader may be able to scoff at polls like Research Co.’s preferred prime minister survey, which suggested that even if Poilievre’s popularity doubled, it would still trail Carney’s.
But byelections are real people putting their “x” on real ballot papers — and they are increasingly disinclined to do so in Poilievre’s favour.
Prime Minister Mark Carney noted that the Liberals won more than 50 per cent of the vote in each of the three byelections held on Monday: in the safe Liberal seat of Beaches—East York, in North Vancouver—Capilano (held by the Conservatives as recently as 2011), and in Chicoutimi—Le Fjord, which was won by Conservative Richard Martel in 2018 and held in three subsequent elections.
In Chicoutimi, the Conservative candidate came in third place with just 12.5 per cent support, garnering barely one-quarter of the votes picked up by Liberal Daniel Gobeil.
The prime minister attributed his party’s success to Canadians being “united and ready” in support of the government’s plan during a time of crisis.
It is hard to argue with his premise that the country is rallying behind what people see as a national unity government, at a time when voters are preoccupied with the trade war with the Trump administration.
By contrast, Poilievre has little to say on the matter.
In March, he went to New York and made a speech that sounded much more accommodating towards America than Carney’s “elbows up” rhetoric and claim that there has been a permanent rupture in relations. Conservatives argued at the time their leader was just being more realistic in recognizing Canada’s geography and limited leverage.
But it was not a winning argument, and he has since made it clear that if voters don’t like his principles, he has others.
After Trump announced his plans to impose additional tariffs on Canada in July, Poilievre wrote an open letter to Carney demanding “no more caving.” He said the government had already made too many concessions to the Americans over the Gordie Howe bridge, the cancellation of the digital services tax, and by overriding the CRTC’s demand that streaming giants like Netflix should pay more of their Canadian revenues to fund homegrown content (a move Poilievre had called for publicly).
The brazen nature of Trump’s strategy in breaching the terms of the Canada-U.S.-Mexico trade agreement by imposing tariffs on autos has forced Poilievre to call such measures “unjustified.”
While he is now more aligned with the public mood, it does not look as if he got any credit at the ballot box.
The Conservative leader’s political obituary has been written countless times already.
Perhaps he will outlast the prime minister, who was asked again on Tuesday whether he intends to lead his party into the next election, and who once again did not answer with a simple affirmative.
The lack of an obvious rival in the Conservative ranks means it is unlikely Poilievre’s job is under immediate threat. But there are another six byelections pending. One in particular — Brantford-Brant South—Six Nations in Ontario — has the potential to set the bell tolling. Larry Brock, the sitting MP, has said he will soon resign and return to Brantford’s Crown attorney’s office. The seat has been safely Conservative since 2008 and Brock won it with 52 per cent of the vote in 2025.
Caucus members will be watching anxiously, because if Brock’s seat is flipped, very few of them will be safe come the next election.
As goes Brantford, so could go the Conservative leadership.
