On November 30, a by-election to fill the vacancy of Councillor for Ward 20, Scarborough Southwest in Toronto, Ontario, Canada will be held.

The seat became vacant on July 26 because of the resignation of former Councillor Gary Crawford, who instead ran in the July 27 by-election held for the vacant Scarborough-Guildwood parliament seat that he did not win.

The nominations to run for the office did not open until September 7 and close at 2 p.m. on October 16.
