A by-election was held in the federal riding of South Surrey—White Rock in British Columbia on December 11, 2017 following the resignation of Conservative MP Dianne Watts. The seat was gained for the Liberals by Gordie Hogg. The by-election result was rare as it saw a seat gain for a governing party. The by election was held on the same day as 3 others across Canada; Battlefords—Lloydminster in Alberta, Bonavista—Burin—Trinity in Newfoundland and Labrador and Scarborough—Agincourt in Ontario.
