2018 Ontario municipal elections

The 2018 municipal elections in Ontario were held on October 22, 2018.

Voters in the province of Ontario elected mayors, councillors, school board trustees and all other elected officials in all of the province's municipalities.

Electoral period
As per the Ontario Municipal Elections Act, 1996, nomination papers for candidates for municipal and school board elections could be filed from May 1, 2018, at which time the campaign period began.

Nominations closed on July 27, 2018, at 2 PM local time. Certification of nomination papers was completed by 4 PM on July 30, 2018.

Voting was on October 22 from 10 AM to 8 PM.

Ranked ballots
In 2016, the provincial government passed Bill 181, the Municipal Elections Modernization Act, which permitted municipalities to adopt ranked ballots for municipal elections.

London was the only municipality to use ranked ballots in the 2018 election itself, with the decision in that city being made by London City Council in 2017, while Kingston and Cambridge held referendums concurrently with their 2018 elections on whether to adopt ranked ballots for the next municipal elections in 2022. Both of the referendums passed, though neither reached the 50 per cent turnout required to make the results legally binding.

In 2020, the provincial government passed Bill 218, the Supporting Ontario's Recovery Act, which, among other things, eliminated the option of ranked balloting for municipalities. The City of London will now have to switch back to first-past-the-post for its 2022 municipal elections.

Online voting
The 2018 elections were also noted for a significant increase in the adoption of online voting. Across Ontario, over 150 municipalities conducted their elections primarily online, with physical polling stations either abandoned entirely or limited to only a few central polling stations for voters who could not or did not want to vote online.

On election day, however, 51 of those municipalities, all of which had selected Dominion Voting Systems as their online voting contractor, were affected by a technical failure. According to Dominion the company's colocation centre provider imposed a bandwidth cap, without authorization from or consultation with Dominion, due to the massive increase in voting traffic in the early evening, thus making it impossible for many voters to get through to the server between 5:00 and 7:30 p.m. All of the affected municipalities extended voting for at least a few hours to compensate for the outage; several, including Pembroke, Waterloo, Prince Edward County and Greater Sudbury, opted to extend voting for a full 24 hours into the evening of October 23.
