The City of St. Thomas has officially opened the nomination period for the 2026 municipal election, inviting residents to step forward for roles in local government. Those interested in running for mayor, one of the eight citywide councillor seats, or school board trustee positions have until 2:00 p.m. on August 21, 2026, to file their paperwork.
This year’s race will bring significant change to the municipal leadership, as incumbent Mayor Joe Preston has announced he will not seek re-election. His departure marks the end of a tenure that began with his first mayoral win in 2018 and includes his most recent victory in 2022. The upcoming election will be the first since 2018 where voters will choose a new mayor to lead the city.
Candidates must file their nomination papers in person, which includes submitting required forms, providing elector endorsements, and paying a filing fee. Standard fees are set at $200 for mayoral hopefuls and $100 for those running for council or school board trustee positions. The Thames Valley District School Board, which serves the community, has been under provincial supervision since April 2025.
Voting for the new municipal representatives will take place on October 26, 2026. Residents will also have the option to cast their ballots remotely through internet and telephone voting, which begins on October 13, 2026. Anyone planning to participate in third-party advertising during the campaign must register their intent before October 23, 2026.
