How does a majority government work? What to know as Carney nears threshold – National | Globalnews.ca


Prime Minister Mark Carney is on the verge of turning his minority government into a majority, a possibility that lies in the results of three byelections Monday.

It’s been seven years since the Liberals enjoyed a majority of seats in the House of Commons, when then-prime minister Justin Trudeau — who came into power with a majority government in 2015 — lost seats in the 2019 federal election and was reduced to a minority.

Since then, the party has had to rely on opposition votes and confidence agreements to survive and pass legislation, which under Trudeau was often shaped by compromise with parties like the NDP.

The Liberals under Carney won 169 seats in last year’s federal election. With the latest floor-crossing from the Conservatives by MP Marilyn Gladu this week, the party now holds 171 seats — just one shy of the 172-seat majority threshold.

While crossing that threshold could make Carney’s political life easier, experts say there will still be ways for the opposition, the public and even Liberal MPs to keep the prime minister in check.

“The same mechanisms of responsible government will still be in place,” said Stewart Prest, a political science lecturer at the University of British Columbia.

Here’s what that could mean in practice.

Stability and legislative power

If the Liberals win just one of Monday’s three byelections, they would have 172 seats and meet the official threshold for a majority — one that is thin, but functional.

However, one of those Liberal MPs is Speaker of the House of Commons Francis Scarpaleggia, who only votes on legislation and motions in the event of a tie.

Because a functional majority would see both the Liberals and the combined opposition parties with 171 voting members on each side, the government would have to rely on the Speaker to break those ties.

Although Scarpaleggia is a Liberal, he’s not required to vote with the government as Speaker, who will normally vote to “maintain the status quo,” according to Parliamentary procedure. That could mean preventing the government from falling in a matter of no confidence, but also to keep debate open on legislation to allow for a majority of MPs to pass it in the future.

If the Liberals win two of the three byelections Monday, they will hold 173 seats, and 174 seats if they win all three byelections, which would let them pass legislation without needing to rely on the Speaker or on any other parties to support them.

The Parliament of Canada website notes that “most majority governments finish their standard four-year term in office between federal elections.”

That doesn’t mean Carney can get fully comfortable, Prest said. Even if the Liberals reach 174 seats, that will still be a slim majority.

“Mr. Carney still has to keep that majority together, he still has to keep the votes within the Liberal caucus on his side,” he said.

“If Mr. Carney really seemed to be no longer serving the interests of the party and Canadians, then there would be conversations within that Liberal caucus, and at the extreme, there would a confidence vote.”

And, just as multiple MPs have crossed the floor from the Conservatives and NDP to the Liberals since December, that possibility exists in the other direction as well.

“There are some more independently-minded Liberal MPs,” Prest said. “And clearly, if a member was willing to cross the floor to the Liberals, if things don’t go the way that they expected, they may choose to cross the floor again, or perhaps sit as an independent.”

Dissent has already shown up in the Liberal caucus under Carney, such as when former heritage minister Steven Guilbeault left cabinet last year in protest over the memorandum of understanding with Alberta on energy policy.


Conservative Leader Pierre Poilievre on Thursday warned Canadians against the possibility of giving Carney “unchecked power” through a majority, which he said was formed by “dirty backroom deals” with floor-crossing MPs.

One reason Prest said he disagreed with the “unchecked power” claim is the current makeup of parliamentary committees, which must review every piece of legislation that passes first and second readings in the House of Commons.

Currently, committees reflect the minority government in the House, meaning opposition members narrowly outnumber the Liberals.

That has allowed the Conservatives and Bloc Quebecois to band together and stall high-profile government bills on immigration, hate crimes and other issues over various concerns.

If the Liberals win a majority on Monday, however, that minority committee structure would remain the same. In order to change it, Carney would have to prorogue Parliament and start a new session that would restructure the committees with a majority of Liberals on each panel.

Carney said he was “absolutely not” considering such a move when asked by reporters this month, adding the possibility “has never even entered my thinking.”

“As long as the committee membership remains the same … there is a real avenue for for influence to ensure that legislation gets through that committee phase of review before it returns to the House of Commons for the third reading of the vote,” Prest said.

Even if Carney does end up proroguing Parliament and changing the committee structure, Prest said opposition members can still collectively influence legislation in a “collaborative spirit.”

If the Liberals decide to ignore that collaboration, he said the opposition can still use the “ultimate check” on politics: public opinion.

“They can bring those kinds of issues up with the population and say the Liberal government is not doing what they promised to do, not doing what Canadians are expecting,” he said.

Liberals dismiss fact-checking petition proposal for House of Commons – National | Globalnews.ca


The Liberal government has dismissed a Toronto man’s proposal to keep politicians honest in an age of misinformation, saying there are already several ways to fight falsehoods.

How does a majority government work? What to know as Carney nears threshold – National | Globalnews.ca

Federico Sanchez initiated an electronic petition to the House of Commons to propose legislation that would help correct the record when members of Parliament stray from the truth intentionally or simply because they are ill-informed.

Sanchez said he was “very upset” by the lack of federal interest in his pitch.

“It made me feel like they didn’t take it seriously,” he said in an interview. “If they don’t think that there’s a problem, then I think we’re going to have a lot worse days ahead.”

The e-petition urged federal politicians to put forward a bill “to address the issue of perceived and actual misinformation being presented by MPs to the public.”

Sanchez, a physician, feared Canada could follow the path of the United States, where he saw an erosion of public trust due to the spread of political misinformation, amplified by artificial intelligence.

The petition called misinformation a growing threat to the democratic process and said a mechanism was needed to verify MPs’ public statements to maintain trust in Canada’s governing body.

It suggested Canada emulate an approach floated in Wales in 2024. Under the model, if a court found a politician made a false or misleading statement of fact, it could issue a notice directing the individual to make a public correction.

If the politician refused to comply with the notice within seven days, without a reasonable excuse, the court could issue an order preventing that politician from holding office in the Welsh Parliament for a set period of time.

A Canadian e-petition must have 500 or more signatures to receive certification for presentation to the House, which opens the door to a formal government response. Sanchez’s petition garnered almost 45,000 signatures from across Canada over a four-month period last year.

In a March 23 response, government House leader Steven MacKinnon said general elections are the “fundamental mechanism” by which voters hold elected representatives accountable.

Beyond elections, Canadians can make their voices heard in other ways, MacKinnon wrote.

Constituents can write to MPs directly on issues of concern or matters of interest, such as real or perceived misinformation, start or sign petitions and attend live parliamentary debates and proceedings, he said. “Committees also seek input from the public on many ongoing studies that are posted publicly.”


Parliament has a duty to hold the government to account, while the executive is responsible to Parliament and remains in power as long as it commands the confidence of the House, MacKinnon added. “Together they are ultimately accountable to electors.”

MacKinnon also noted the House has the right to discipline members who abuse or breach privileges, such as freedom of speech, and to find members in contempt of Parliament.

Sanchez characterized the federal suggestions for ensuring accuracy and truth in politics as glib, offhand and ultimately unworkable.

He said it is unrealistic for voters to wait years until a general election to hold politicians accountable for misstatements of fact.

When politicians lie without recourse, “you’re not making election decisions based on what’s actually happening,” he said. “It’s based on who lies the best.”

Sanchez also scoffed at MacKinnon’s suggestion that concerned voters could voice their concerns through a petition.

“Well, this is clearly what I’m doing,” he said. “But if you’re going to get a response like this for your petition, it really kind of makes me question whether petitions actually are taken seriously by Parliament at all.”

NDP MP Lori Idlout crosses floor to Liberals – National | Globalnews.ca


The NDP Interim Leader, Don Davies, says Nunavut MP Lori Idlout has left the party to sit with the Liberals, bringing Prime Minister Mark Carney‘s government closer to a majority.

Her departure follows the recent defection of three Conservative MPs in recent months.

“We’re very disappointed,” Davies said in a statement issued late Tuesday.

His statement says the NDP’s position is that if an MP wants to change parties they should resign their seat and run under a new banner to let voters decide.

This latest floor crossing could help give the Carney government a majority, as the Liberals now need to win two of three April 13 byelections to have a narrow majority.

Idlout has represented Nunavut in the House of Commons since 2021, and just appeared at an Avi Lewis NDP leadership campaign event in Ottawa last Thursday.

A majority of Canadians say members of Parliament should not be allowed to cross the floor to another party and should face an “immediate” byelection if they do so, a new poll suggests.


However, Wednesday’s Ipsos poll conducted exclusively for Global News found Canadians’ displeasure with floor-crossing MPs has not hurt the overall approval for Prime Minister Mark Carney or his Liberal government.

In fact, those approval numbers have gone up since last year, with over one-third of Canadians saying they are even more supportive of Carney after three MPs left the Conservatives to join the Liberals in recent months.

Carney calls byelections for 2 Ontario ridings, 1 in Quebec | Globalnews.ca


All eyes will be on three federal byelections in April as a sweep by the Liberals could put them in razor-thin majority territory.

How does a majority government work? What to know as Carney nears threshold – National | Globalnews.ca

Prime Minister Mark Carney on Sunday called byelections for the Ontario ridings of Scarborough Southwest and University-Rosedale, and the Quebec riding of Terrebonne. The votes will be held April 13.

The two Ontario ridings are those once held by former ministers Bill Blair and Chrystia Freeland, respectively.

Blair was appointed to be Canada’s high commissioner to the United Kingdom, while Freeland stepped down after taking on a voluntary role as advisor to Ukrainian President Volodymyr Zelenskyy. Freeland is also taking the helm as CEO of the Rhodes Trust educational charity starting in July.

People in Scarborough may be watching to see if former provincial NDP deputy leader Doly Begum holds the long-time Liberal stronghold. Begum triggered a wave of political activity last month when she made the shock announcement she would resign from the Ontario NDP to run in this byelection for the federal Liberals.

But it’s the Quebec riding of Terrebonne that will be a focus point for many, after Liberal Tatiana Auguste lost her Montreal-area seat when the Supreme Court of Canada invalidated last year’s election result.

Elections Canada declared Auguste the winner over the Bloc-Quebecois’ Nathalie Sinclair-Desgagne by a single vote following the April 28 federal election.

Sinclair-Desgagne challenged the results when a supporter complained she had tried to vote by mail using a special ballot that was never counted. She won her case at the top court on Feb. 13.

Following the ruling, the Bloc announced Sinclair-Desgagne as their candidate and the Liberals officially nominated Auguste the same week, setting up a face-off once again.

The stakes could be higher on April 13, as the Liberals are three seats shy of the 172 seats needed for a majority government.

If they win all three byelections, that would put them at 172. Yet they could still run into difficulty as the Speaker of the House is a Liberal, Francis Scarpaleggia. He would only vote with his party on matters of confidence to keep the House running. To maintain impartiality, House Speakers typically do not vote on legislation.

The Liberals have been able to get so close to a majority, in part, due to three Conservative MPs crossing the floor to join the government. Chris d’Entremont joined in the fall, with Michael Ma becoming a Liberal prior to the Christmas break. Matt Jeneroux also crossed last month after initially saying last fall he planned to resign his seat altogether.

Should the Liberals win Scarborough Southwest, University-Rosedale and Terrebonne, they would still need one more floor-crosser in order to have a working majority and be able to pass legislation without the support of another party.

Elections Canada had declared Auguste the winner over Sinclair-Desgagné by a single vote following the April 28 federal election.

But Sinclair-Desgagné challenged the results after a supporter complained that she had tried to vote by mail using a special ballot that was never counted. She won her case at the top court on Feb. 13.

“The last few months have been particularly difficult. We had to fight hard for fundamental principles, for the principle of democracy and the principle that every vote counts,” Sinclair-Desgagné said.

Bloc Leader Yves-François Blanchet officially announced Sinclair-Desgagné as his candidate Thursday for the impending byelection, paying tribute to her tenacity.

“The fact that we are here today is due to the determination and relentless drive of Nathalie Sinclair-Desgagné,” Blanchet told supporters gathered at a local hotel on Thursday.

The Liberals, for their part, officially nominated Auguste on Wednesday night in the Montreal-area riding.


The Liberal Party of Canada is three seats short of a majority government, and Terrebonne is one of three ridings up for a byelection in the coming months.

The other two byelections will take place in Liberal strongholds in the Toronto ridings of Scarborough Southwest and University—Rosedale. Prime Minister Mark Carney has not yet announced a date for the byelections.

Currently, the Liberals hold 169 seats, the Conservatives 141, the Bloc Québécois 22, the New Democrats seven, and the Greens one.

Sinclair-Desgagné acknowledged people across the country will be paying attention to what happens in the riding since it could decide whether Carney gets a majority in the House of Commons. But she said Terrebonne residents will also want to discuss local issues such as the high-speed rail project between Quebec City and Toronto, which will pass through the Quebec riding and likely involve expropriations.

Several politicians, both provincially and federally, have been weighing bids and assembling teams in the background but have been waiting for the date and rules of the upcoming leadership race before making any official announcements.

Party president Kathryn McGarry said in a statement that the race is an opportunity for the party to build momentum and bring Liberals together

The winner of the leadership contest will replace Bonnie Crombie, who officially resigned earlier this year following lukewarm support in a vote at the party’s annual general meeting in the fall.

Crombie led the provincial Liberals back to official party status and increased their seat count in last year’s snap election, but she failed to win her own seat and the party did not form the Official Opposition despite receiving nearly 600,000 more votes than the NDP.

Liberal MP Nate Erskine-Smith, who finished second to Crombie in the 2023 leadership race, has strongly suggested he will give it another go, and has said he will seek the provincial party’s nomination for an upcoming byelection in the Toronto riding of Scarborough Southwest.

Ontario Liberal caucus members Lee Fairclough, Adil Shamji and Rob Cerjanec have also said they are seriously considering jumping into the leadership race when it is called.

Former Liberal party president Mike Crawley is said to be weighing a run, as is housing advocate Eric Lombardi.

Ontario Liberal leader hopefuls have until July 31 at 5 p.m. to submit their nomination papers.

Party members will cast their votes electronically between Nov. 9 and Nov. 20 using a ranked ballot system.
