Toronto municipal election, 1978

The Toronto municipal election of 1978 held on Monday, November 13, 1978, was the first seriously contested mayoralty race in Toronto, Ontario, Canada, since David Crombie took office in the 1972 election. Crombie left municipal politics earlier in 1978 to seek and win a seat in the Canadian House of Commons as the Progressive Conservative Member of Parliament for Rosedale electoral district.

The contest to succeed Crombie (or more correctly, interim Mayor Fred Beavis) was a wide-open affair that saw three aldermen, David Smith, Tony O'Donohue and John Sewell contest the position.

Though O'Donohue and Smith were both aligned with the Liberals with links to developers, O'Donohue was seen as more right-wing and won the endorsement of the conservative Toronto Sun newspaper, while Smith was seen as more of a centrist.

Sewell had first been elected to Toronto city council in 1969 and had a reputation as a community activist and even a radical. His backers consisted of New Democratic Party supporters (although Sewell himself has never been a member of the party), left-wing Liberals and Red Tories, many of whom had supported Crombie who, despite his Tory allegiance, had a reputation as a reform mayor on the left-wing of the municipal political spectrum.
