2018 Municipal Election Analysis

Election Summary

414 municipalities held direct elections in 2018 - 26 of which had their entire council acclaimed.

The candidates for the position of Regional Chair were on the ballot of the lower tier municipality.

474 positions were uncontested and were therefore acclaimed.

Women comprised 27.2% of candidates – and 29.4% of elected or acclaimed candidates. Incumbents comprised 33.9% of candidates and captured 58.7% of seats available.


1,808 of the 6,655 candidates in this election were women. That’s 27% of the total pool of candidates – and a moderate increase over the 24% seen in the 2014 election.

Success Rates

A candidate’s electoral success depends on the magnitude of her competition, the recognition of her name among the electorate, the size of her war chest, and other factors.  Our data cannot account for all of these influences; information below should be interpreted with caution.

Women were slightly more successful than men in Ontario’s 2018 municipal elections (Table 1). Of 1,810 female candidates, 46.4% were successful. In contrast, 41.4% of the 4,846 men running were successful. Two candidates did not have a specified sex in our data; both were unsuccessful.

Incumbents enjoyed a substantial advantage (Table 2). Of 1,939 incumbents running for the same office, 76.5% were successful. Of 318 incumbents running for a different office, 57.5% were successful. In contrast, 26.7% of the 4,401 candidates running for the first time were successful.

Women and men were equally likely to be incumbents. Women nevertheless experienced greater electoral success than men whether running as an incumbent for a new office, an incumbent for the same office, or a new candidate (Table 3).

Turnover Rates

Municipalities experienced an average turnover of 41.5%; new candidates captured 41.3% of seats available. Turnover ranged from 0% in 25 municipalities to 100% in 11 municipalities.
