Canadian Prime Minister Mark Carney's Liberal Party secured a parliamentary majority on Monday, April 13, 2026, after winning byelections — votes held to fill vacant parliamentary seats outside of a general election — in three districts, including a Toronto riding where the result was projected by the Canadian Broadcasting Corporation. The milestone marks a remarkable consolidation of power for a government that, just over a year ago, many analysts had written off entirely.

The majority did not come through a single election alone. In the months leading up to Monday's results, the Liberals quietly assembled a broader coalition through an almost unprecedented string of floor crossings — the practice of an elected lawmaker switching parties without triggering a new vote. Four Conservative MPs defected to the Liberals, including Marilyn Gladu, a social conservative who had previously criticised floor crossings. An NDP member from Nunavut also joined Carney's team, while the deputy leader of Ontario's NDP is running as a Liberal. Conservative leader Pierre Poilievre accused Carney of "seizing a costly Liberal majority that voters denied him" through "backroom deals," a charge the government dismissed.

To understand how the Liberals arrived here, it is necessary to revisit April 2025. Carney's party entered that federal election facing a Conservative Party that had held a roughly 25-point polling lead for over two years. Two events scrambled that calculus. First, Justin Trudeau resigned under intense pressure in early January 2025, allowing the Liberal brand to reset almost immediately. Second, the return of Donald Trump to the US presidency brought sweeping tariffs and open threats to annex Canada as a "51st state," reframing the entire election as a question of national resilience. Carney, a former central banker with no prior elected office, presented himself not as a continuation of Trudeau but as a technocratic guardian in a moment of crisis. The Liberals won 43.8 per cent of the vote to the Conservatives' 41.3 per cent, a result described as unimaginable months earlier.

Data from the 2025 Canadian Election Study show how decisive this framing proved. Nearly 58 per cent of Canadians across all partisan groups — including majorities of NDP and Bloc Québécois supporters — identified the Liberals as best suited to manage the relationship with the United States. In an unusual pattern, a majority of traditional NDP voters cast their ballots for the Liberals, strategic voting that was central to the minority victory. Polling conducted in early 2026 shows the Liberals holding a six-point national lead, with a 52 per cent government approval rating and Carney's personal net favourability at plus 20.

Yet the path to majority has not been without friction. Gladu's defection in particular ignited a debate within Liberal ranks about the party's values. She holds anti-abortion views that clash with longstanding Liberal policy; under Trudeau, Liberal candidates were required to be pro-choice. Carney has stated there is "no change in the Liberal party's values" and that Gladu has committed to voting with the government on reproductive rights. Critics, including some within his own party, warn that the pursuit of a broad coalition risks undermining the very non-partisan image that has been Carney's greatest political asset. As one analyst put it: "The minute you call an election just to get a majority, you've lost that." Whether Carney can maintain that balance — and whether Trump's shadow continues to shield him from ordinary political scrutiny — will define the next chapter of his government.
