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.
