Prime Minister Mark Carney’s administration is poised for a significant shift as the Liberal Party anticipates by-election victories in Toronto and Quebec, which could secure them a majority in the House of Commons. This pivotal moment follows a series of floor crossings that have seen five opposition MPs join the Liberals since November, a rare phenomenon in Canada’s political landscape. With the party currently one seat shy of a majority, the stakes are high.
A Historic Political Landscape
The upcoming by-elections are expected to be a turning point for the Liberals, particularly as two of the contested ridings are considered strongholds for the party. Since the last election, the Liberals have been actively courting opposition members, resulting in an unprecedented number of defections. With the latest addition of MP Marilyn Gladu, the Liberals now hold 171 seats, surpassing the combined total of opposition MPs, albeit with three vacancies still to be filled.
The political climate has shifted dramatically since April 2025, when voters first granted Carney a minority government, securing 169 out of 343 available seats. The Conservatives emerged as the Official Opposition with 144 seats. The Liberal strategy to attract defectors has proven effective, with reports suggesting that as many as eight additional MPs from other parties are being considered for recruitment.
The Road to Majority
The significance of these by-elections cannot be overstated. Should the Liberals claim victory in both Toronto ridings, they would achieve a total of 173 seats, effectively securing a majority. The third by-election, in Quebec’s Terrebonne riding, presents a more precarious challenge. Previously won by a razor-thin margin, the Liberal claim to this seat was annulled by the Supreme Court, making the outcome uncertain.
At the Liberal convention in Montreal, party officials exuded confidence, mobilising high-profile MPs and volunteers to bolster support for candidate Tatiana Auguste in Terrebonne. Carney’s speech underscored a commitment to national unity and a vision of a stronger Canada, urging party members to rise above petty political squabbles. “This is not the time for politics as usual,” he declared, emphasizing a collective approach to governance.
Future Implications
The anticipated by-election results are expected to reshape the Liberals’ legislative strategy and operational dynamics. A shift to a majority government would allow for greater control over parliamentary committees, which are currently seen as a barrier to the Liberals’ legislative ambitions due to the opposition’s narrow majority in these bodies.
Kody Blois, a parliamentary secretary to Carney, noted that if a clear majority emerges from the by-elections, it would enable the government to focus on its agenda without the looming threat of an imminent election. The internal atmosphere would likely shift towards a more confident approach, but this comes with heightened expectations from the public and stakeholders.
Despite the potential for increased political capital, Ralph Goodale, a former Liberal MP and cabinet minister, cautioned that a majority does not absolve the government from delivering results. “As the internal confidence level goes up, externally, the level of expectation will go up,” he stated. The pressure to demonstrate tangible outcomes and effective governance could intensify.
Why it Matters
The results of these by-elections will not only dictate the immediate power dynamics within Parliament but will also shape the long-term trajectory of Carney’s administration. A majority government could streamline legislative processes, enabling the Liberals to implement their agenda more effectively. However, it also places the onus on the government to fulfil its promises and address pressing issues faced by Canadians, particularly in light of rising living costs and energy prices. The coming days could thus mark a defining moment for both the Liberal Party and the broader Canadian political landscape.
