Melissa Lantsman (Conservative Party of Canada) is MP for Thornhill, a riding (a federal electoral district, which elects one MP) named after the town. Thornhill sends one MPP (Member of Provincial Parliament, at Queen’s Park in Toronto) to the Legislative Assembly of Ontario from the riding of the same name, though no open record we can reuse gives the name. Vaughan, which governs Thornhill, elected Steven Del Duca mayor in October 2022. Ontario held new municipal elections on 26 October 2026; until the province publishes them, the open record stops at the council elected in 2022.

- Which riding. Where residents of the 2021 Census live decides the riding; any riding with 5% of them or more is named.
- Election results. Two maps are in play: the 2013 ridings, on which 2019 and 2021 were counted, and the 2023 ridings, onto which Elections Canada transposed the 2021 vote poll by poll.
- Not on this page. No party tally for the council, which the open lists don’t record, and no band councils.
- Who holds each seat. The members named here are Wikidata’s, kept up by volunteers; a by-election or a floor crossing may take a few days to show.
- Council money. The 2024 Financial Information Return, totals after adjustments by service, per resident with the return’s own population. A lower tier’s figures leave out its county’s or region’s spending, so lower tiers are compared only with lower tiers.
- Council size. Every seat counts, the head of council’s too, against the population of the 2021 Census.
