Sometime in 2025, a by-election will be coming in Quebec for the provincial riding of Arthabaska for a seat in the province’s National Assembly of Quebec. MNA Éric Lefebvre resigned on March 18 to run with the Conservative Party of Canada for the federal riding of Richmond-Arthabaska (Quebec) for a seat in the Canadian House of Commons.

The by-election date in the Arthabaska electoral division has not yet been determined, according to Elections Quebec. Prime Minister François Legault has six months to call a by-election.

The federal by-election for the electoral district of Halifax (Nova Scotia) to fill a vacancy in the House of Commons has been cancelled.

Originally scheduled for April 14, Elections Canada announced that because A federal general election has been called for April 28, the previously scheduled by-election for the electoral district will be held on that date. Technically, the electoral district may change for the general election and have new electoral boundaries.

Member of Parliament Andy Fillmore, who had occupied the seat, resigned on August 31 of last year to run for Halifax mayor. On March 23, Prime Minister Mark Carney called the snap federal election because his Liberal Party was not able to form a majority government.

On March 23, Prime Minister Mark Carney called a snap federal election for April 28. Carney won the race to become leader of Canada’s ruling Liberal Party earlier this month. In January, Prime Minister Justin Trudeau had stepped down, requiring the ruling Liberal Party to hold their election to replace him. A federal election was expected to be held on October 20 of this year, but the Liberal Party was not able to form a majority government, which caused Carney to have to call for this earlier election date.

On March 19, the Chief Electoral Officer of Canada, Stéphane Perrault, received official notice from the Speaker of the House of Commons that the seat for Eglinton–Lawrence (Ontario) is vacant. Marco Mendicino resigned his seat in Parliament to become Chief of Staff to newly elected Prime Minister Mark Carney. Under the law, if a vacancy occurs less than nine months before the fixed date for a general election, no by-election is called, and the seat remains vacant until the general election. Therefore, no by-election will be held to fill this vacant seat.

On March 9, former central banker Mark Carney won the race to become leader of Canada’s ruling Liberal Party. Carney won 86% of the votes cast, beating former Finance Minister Chrystia Freeland. In January, Prime Minister Justin Trudeau had announced he would step down, which forced the ruling Liberal Party to hold their election to replace him. While a federal election must be held by October 20 of this year, the Liberal Party is not likely to form a majority government, and so Carney is expected to call for an earlier election date.

On March 7, the Supreme Court of Canada ruled Ontario’s law limiting spending by third-party political advertising violates the right to vote guaranteed by the Canadian Charter of Rights and Freedom.

The court concluded in its decision that, “By design, [the law] creates absolute disproportionality, or a disproportionality that is so marked on its face that it allows political parties to drown out the voices of third parties on political issues from reaching citizens during an entire year of legislative activity.”

Ontario’s Election Finances Act restricts the amount that third parties can spend on political advertising in the year before a provincial election period. Specifically, the law limits spending on third party advertising to $24,000 in any one electoral district and to $600,000 in total during the 12-month period before an election period. While it also regulates political advertising by political parties during the six-month period before an election, they are not subject to the same spending limits or time period restrictions.

The court reasoned, “When political parties face no limitations, curtailing the ability of third parties to use platforms that may be effective in reaching certain voters has the potential to overwhelm the political discourse and drown out third parties, thus interfering with citizens’ access to information letting them weigh and establish their views during an important time in the democratic cycle.”

A third party is any person or entity, other than a registered candidate, registered constituency association, or registered party, engaging in election advertising and may be a corporation, an unincorporated association, or a partnership.

On March 4, the Legislative Assembly of the Northwest Territories recommended to the Commissioner the reappointment of Stephen Dunbar as Chief Electoral Officer (CEO) for a second consecutive four-year term.

According to the Public Affairs and Communications division of the legislature, Dunbar is currently leading a full repeal and replacement of the Elections and Plebiscites Act and is engaging with the NWT Association of Communities to discuss expanding Elections NWT’s mandate.

Dunbar, who was born and raised in the Northwest Territories, was appointed CEO of Elections NWT on November 25, 2021.

On April 14, a Canadian federal by-election will be held in the electoral district of Halifax (Nova Scotia) to fill a vacancy in the House of Commons. On March 2, Prime Minister Justin Trudeau officially announced the district’s by-election date. Member of Parliament Andy Fillmore, who had occupied the seat, resigned on August 31 of last year to run for Halifax mayor.

Because the vacancy occurred more than nine months before Canada’s fixed general election date of October 20, 2025, the by-election will take place before then. If a general election is called before election day for the by-election in Halifax, the by-election will be canceled.

On March 18, Manitoba will hold a by-election for the provincial constituency of Transcona. Advance voting will begin on March 8.
