Opinion polling for the 2025 Canadian federal election

National Polling and Methodology

National opinion polls for the 2025 election were conducted by a variety of established firms using scientific methodologies to ensure representativeness. These surveys typically sampled the Canadian adult population, with data weighted by factors such as age, gender, region, and education to mirror the broader electorate. The primary focus of these polls was to track voting intention, asking respondents which federal party they would support if an election were held at the time of the survey. Polling occurred continuously during the pre-campaign period and intensified once the election was formally called on March 23, 2025. Firms like Leger, the Angus Reid Institute, and Ipsos regularly published their findings, contributing to a public polling average that aggregated results from hundreds of individual surveys.

Campaign Period Polling Dynamics

The official campaign period, lasting from March 23 to April 28, 2025, saw a marked increase in the frequency and scrutiny of opinion polls. Daily tracking polls became common, offering a near real-time snapshot of the race as leaders crisscrossed the country. These polls measured the immediate impact of debates, policy announcements, and campaign events on party support. The central contest was primarily between the incumbent Liberals, led by Justin Trudeau, and the opposition Conservatives. Polling during this phase was critical for identifying swing regions and voter segments that could determine the election outcome. The final polls released just before the blackout period provided the last indications of possible results, though they carried margins of error.

Leadership and Best Prime Minister Polls

Separate from voting intention, polling firms consistently surveyed public opinion on party leadership. A key question asked which leader would make the best prime minister, providing insight into personal approval ratings separate from party brand. These polls tracked the standings of Justin Trudeau, Conservative Leader Pierre Poilievre, NDP Leader Jagmeet Singh, and others throughout the pre-campaign and campaign periods. Leadership polls often revealed strengths or weaknesses in a leader's perceived competence on specific issues like the economy or integrity. The data was segmented by time, with distinct periods such as February to September 2022 and March to April 2025, showing how perceptions evolved in response to political events and scandals.

Hypothetical Scenarios and Successor Polling

Pollsters frequently tested hypothetical electoral scenarios to gauge potential shifts in the political landscape. A significant line of inquiry involved public reaction to a formal merger or electoral alliance between the Liberal Party and the New Democratic Party. These polls were conducted under both Justin Trudeau and Jagmeet Singh's leadership to measure the combined appeal. Another common scenario polled voting intentions under different Liberal leaders, speculating on potential successors to Trudeau. Firms posed questions about how the public would vote if figures like Mark Carney, Chrystia Freeland, or Karina Gould were leading the Liberal Party. These speculative polls were often reported in political analysis to discuss the party's future direction and voter appeal.

Regional and Provincial Polling

Given Canada's regional political diversity, many polling firms conducted surveys focused on specific provinces or areas. Stand-alone regional polls, not just subsets of national samples, provided deeper insight into key battlegrounds like Ontario, Quebec, Alberta, and British Columbia. Sub-regional polls examined voting intentions in critical urban areas such as the City of Toronto, Peel Region, and the City of Mississauga. In Atlantic Canada, polls were broken down for New Brunswick, Nova Scotia, Newfoundland and Labrador, and Prince Edward Island. This granular data was essential for understanding seat distribution, as the first-past-the-post system makes provincial swings decisive for determining which party forms government.

Seat Projections and Advanced Modelling

Beyond simple vote share, some pollsters and analysts used advanced statistical models to project seat totals in the House of Commons. Ahead of the election, YouGov published a Multilevel Regression with Poststratification model, a large-scale polling methodology that enables seat-by-seat prediction. These projections were a vital tool for commentators and parties, offering a more concrete picture of the possible election outcome than national vote percentages alone. They highlighted the importance of regional concentration of support, which can lead to disparities between popular vote and seat count.

Government Approval and Post-Election Polling

Throughout the electoral cycle, polls consistently measured government approval and performance on specific issues. These surveys asked respondents whether they approved of the government's overall performance or its handling of key files like the economy, healthcare, and affordability. After the 2025 election, polling continued to track public sentiment toward the government and its agenda. For instance, an October 2026 Leger poll showed steady approval for Prime Minister Mark Carney but weaker ratings on affordability issues. Another post-election poll indicated that 73 percent of Canadians supported Carney continuing his economic reforms without calling a new election, with the Liberal Party receiving 46 percent support in that context.

Polling Accuracy and Public Discourse

The reliability and influence of election polls are perennial topics in Canadian political discourse. Polls are subject to margins of error, methodological challenges, and potential last-minute shifts in voter behaviour. Despite these limitations, they play a significant role in informing media coverage, shaping campaign narratives, and influencing strategic decisions by political parties. The aggregation of polls into rolling averages, such as those tracked by platforms like PolitPro, aimed to provide a more stable picture of the race by smoothing out outliers. The 2025 election cycle saw the continued use of online panels, like the Angus Reid Forum, which are designed to be representative of the Canadian population by key demographics.

Questions about Opinion polling for the 2025 Canadian federal election

When did the campaign period for the 2025 election begin?

The official campaign period for the April 28, 2025 election began after the election was called on March 23, 2025. This marked the start of the regulated period where spending limits and broadcasting rules apply. Polling frequency increased significantly during this five-week campaign. The election day itself was April 28, 2025.

What did polls say about a possible Liberal-NDP merger?

Pollsters frequently tested hypothetical scenarios involving a Liberal-NDP merger or electoral alliance. These polls measured voting intention for a combined entity under the leadership of either Justin Trudeau or Jagmeet Singh. The results were used to analyze the potential impact of such a political union on the electoral landscape. These speculative polls were a feature of pre-campaign political analysis.

How are seat projections different from national vote polls?

Seat projections use advanced modelling, like YouGov's MRP model, to predict how vote share translates into wins in individual ridings. National vote polls only show overall percentage support. Seat projections are crucial in Canada's first-past-the-post system, as regional concentration of support determines who forms government. They provide a more concrete forecast of the parliamentary outcome.

Which polling firms are most active in Canadian federal politics?

Leading firms in Canadian federal polling include Leger, the Angus Reid Institute, Ipsos, and Abacus Data. These organizations conduct regular scientific surveys using online panels and telephone interviews. Their methodologies involve weighting samples to be representative of the Canadian adult population. Their results are widely reported in media and aggregated into public polling averages.

What issues were tracked in government approval polls after the 2025 election?

Post-election government approval polls, such as one from Leger in October 2026, tracked Prime Minister Mark Carney's overall approval and performance on specific issues. Affordability was a notable area where the government received weaker ratings in these surveys. Another poll showed strong support for Carney continuing his economic reforms without a new election. These polls measure the enduring public mandate for government policies.
