Canada’s governing Liberal Party has celebrated a major political victory after winning all three federal by-elections held on Monday, but the party could face a fresh test in the coming months as several more vacant parliamentary seats are expected to go to the polls.
Under Prime Minister Mark Carney, the Liberals won seats in Ontario, British Columbia and Quebec, securing more than 50 percent of the vote in each of the three ridings.
Liberals Complete By-Election Sweep
The Liberals retained the North Vancouver–Capilano and Beaches–East York ridings while also capturing Chicoutimi–Le Fjord in Quebec from the Conservative Party.
The three victories gave the Liberal government an early political boost and allowed the party to portray the results as evidence of public support for its policies.
Speaking to reporters in Ottawa on Tuesday, Prime Minister Mark Carney said he believed the message from Canadian voters was clear.
Carney said Canadians had expressed support for the government’s plans and suggested that national unity was one of the reasons behind the results.
Two Liberal Seats Were Considered Safe
Political analysts cautioned that the Liberal victories in North Vancouver–Capilano and Beaches–East York were not particularly surprising.
Dalhousie University political science professor Lori Turnbull said both ridings had already been considered relatively safe Liberal seats.
Maintaining those constituencies therefore did not represent an unexpected political breakthrough for the governing party.
However, the Liberal victory in Chicoutimi–Le Fjord is considered more politically significant because the party took the riding from the Conservatives.
Trade War Could Have Influenced Quebec Result
Turnbull said the victory of Liberal candidate Daniel Gobeil in Chicoutimi–Le Fjord could also be viewed as a sign of voter confidence in Carney’s handling of the ongoing trade dispute with the United States.
The Liberal campaign also appeared to send a specific political message through its choice of candidate.
Gobeil’s background as a dairy farmer highlighted the government’s commitment to protecting Canada’s supply-management system, an issue that remains particularly sensitive during trade negotiations with the United States.
Agriculture and supply management have become important political issues as Canada continues to deal with economic and trade pressures involving its largest trading partner.
More Parliamentary Seats Are Now Vacant
Despite the Liberal sweep, the political contest is far from over.
Several parliamentary seats are now vacant and will eventually have to be filled through federal by-elections.
Three members of Parliament resigned within the past week, bringing the number of officially vacant seats to five.
If Ontario Conservative MP Larry Brock follows through with his announced plan to resign later this month, the number of upcoming by-elections could rise to six.
Recent Resignations
Conservative MP Cathay Wagantall formally resigned her Saskatchewan seat on Monday.
Former Liberal cabinet minister Steven Guilbeault had previously announced that he would leave his parliamentary seat. His resignation was part of a broader series of departures from the House of Commons.
Former New Democratic Party MP Alexandre Boulerice also resigned last week to pursue provincial politics in Quebec.
Bloc Québécois MP Simon-Pierre Savard-Tremblay resigned in June, with provincial politics also cited as a reason for his departure.
Liberal MP Shaun Chen left his parliamentary seat in mid-August.
These resignations could lead to a series of by-elections across different provinces and in ridings with very different political profiles.
Political Temperature Could Rise
Political analyst Eric Grenier said current polling suggests the Liberals may have a strong chance of defending several of the seats they previously held.
The governing party could potentially strengthen its position further if it manages to win some of the upcoming contests.
According to Grenier, the coming by-elections could therefore provide a useful indication of the direction of Canadian voter sentiment following the federal election and amid ongoing economic and political uncertainty.
Pressure on Conservatives
One of the most closely watched potential contests could be in Brantford–Brant South–Six Nations, the riding represented by Conservative MP Larry Brock.
The riding has traditionally been viewed as relatively favourable to the Conservatives, but recent election results suggest the Liberals have been making gains.
Brock won the riding in the 2025 federal election with slightly more than 50 percent of the vote.
The Liberals, meanwhile, received roughly 40 percent, representing a significant improvement compared with their previous performance in the riding.
In earlier versions of the riding, the Liberal vote share had generally been around 30 percent.
The narrowing gap could make a future by-election considerably more competitive.
Attention on Pierre Poilievre
Grenier said the potential contest in Brantford–Brant South–Six Nations could also create pressure for Conservative Leader Pierre Poilievre.
If the Liberals increase their vote share substantially or manage to win the riding, the result could be viewed as an important setback for the Conservatives.
For the Conservative Party, however, the contest would also provide an opportunity to demonstrate that it continues to have strong support in key areas and remains competitive outside its traditional strongholds.
Six Potential By-Elections Could Be Important
The Liberal Party’s three victories on Monday have undoubtedly strengthened Prime Minister Mark Carney’s political position in the short term.
However, the next round of by-elections could provide a much broader test.
With potentially six seats becoming available across different provinces and political environments, the contests could offer a clearer picture of how Canadian voters currently view the major federal parties.
The elections could test not only the popularity of the Liberal government but also the strength of Poilievre’s Conservatives and other opposition parties.
Issues such as the Canada-U.S. trade relationship, economic pressure, affordability and broader concerns about Canada’s economic future are likely to influence the upcoming campaigns.
For the Liberals, the immediate challenge will be to turn the momentum from Monday’s sweep into sustained support.
For the Conservatives, the upcoming races will provide an opportunity to stop Liberal gains and demonstrate that the party remains a major force in Canadian federal politics.
The next several months could therefore offer an important measure of Canada’s changing political landscape.
