A by-election will be held to elect a member of Parliament (MP) to represent Scarborough North, Ontario, in the House of Commons of Canada for the remainder of the 45th Canadian Parliament following the resignation of Liberal MP Shaun Chen.

Background Liberal MP Shaun Chen was first elected to the House of Commons in the 2015 Canadian federal election and was re-elected in 2019, 2021, and 2025. Prior to entering federal politics, Chen served as chair of the Toronto District School Board.

On August 10, 2026, Chen announced that he would resign as a member of Parliament effective August 15, citing ongoing health issues resulting from a car accident in late 2025. Chen said that his injuries had prevented him from travelling to Ottawa as frequently as his parliamentary duties required.
