The city of Ottawa, Canada held municipal elections on November 10, 1980.
Mayor Marion Dewar defeated former alderman Pat Nicol in a re-match of the 1978 race. This is the first election in 70 years without the Ottawa Board of Control, as it had been abolished. Council stayed the same size however, as four wards were added.
Marion Dewar swept the city in her re-election, winning all but one ward. Her best results came in the city's urban wards, with her best ward being Capital, where she won 63.4% of the vote. She also topped 60% in By-Rideau, St. George's and Wellington wards. Her only loss was in Elmdale, which Nicol won narrowly by 43 votes. Nicol represented Elmdale on city council.[1]
