Brad Loosley was elected mayor of Petrolia in October 2022, on a council of 7 seats. Ontario held new municipal elections on 26 October 2026; until the province publishes them, the open record stops at the council elected in 2022. Petrolia is in Sarnia—Lambton—Bkejwanong, its riding (a federal electoral district, which elects one MP), and the seat belongs to Marilyn Gladu of the Conservative Party of Canada. Provincially, Petrolia votes in Sarnia—Lambton; the open record doesn’t name its MPP (Member of Provincial Parliament, at Queen’s Park in Toronto) in the Legislative Assembly of Ontario, so the legislature’s own list is linked below.
