The 2011 Lethbridge municipal by-election was held Tuesday, February 1, 2011 to elect one aldermen at-large. On October 18, 2010, Bob Babki was elected to the eight alderman council, in the regular scheduled municipal election. He died on October 30, from a suspected heart failure, two days before he would have been sworn into office. Minister of Municipal AffairsHector Goudreau wrote Mayor Rajko Dodic, and by extension all citizens of Lethbridge, on November 18, that because Alderman-elect Babki was declared elected, a by-election would be required. The Municipal Government Act requires the City to hold a by-election within 90 days of a vacancy, since the vacancy did not occur until the new council was sworn in on November 1, 2010, it would have been January 30, 2011 at the latest, the two day discrepancy was not explained on the City election website. Of the 68,294 eligible voters, only 8,843 turned in a ballot, a voter turnout of 12.9%.
