Notes on this record
How the lists were read, and what could not be.
- Ridings covering the municipality (share of its land area on a sample grid, not population — Represent census subdivision outline vs Élections Québec's 2026 riding map): Deux-Montagnes 99.2%. Slivers under 3.0% ignored: Mirabel 0.4%, Groulx 0.1%.
- Deux-Montagnes: Linda Vaillant (PQ) elected with 12,575 votes, 36.42%, ahead of Marc Allaire (PLQ/QLP, 22.35%) by 4,858 votes (14.07 points). No outgoing MNA ran in this riding (per Élections Québec's candidate file); the source does not say who held the seat before the 2026 map or whether they retired.
- Results are validated: Source flags isResultatsFinaux=true for all 127 ridings (official results after the recensement des votes), last updated 2026-10-08T10:13:52,000-04:00. Élections Québec states the Rapport des résultats officiels du scrutin prevails over web content; judicial recounts, if any, are not reflected here.
- Riding map: Élections Québec's 2026 map (https://donnees.electionsquebec.qc.ca/autres/geojson/circ_2026_sanseau.json, 127 ridings). Represent (represent.opennorth.ca) carries only the 2017 Quebec map (used in 2018 and 2022); its 2017 riding at this centre is Deux-Montagnes.
- Municipal council from Ville de Saint-Eustache's Conseil municipal page (https://www.saint-eustache.ca/ville/vie-democratique/conseil-municipal, retrieved 2026-10-09): Mayor + 10 district councillors. Party as printed in the city's 'Résultats officiels aux élections municipales 2025' (https://www.saint-eustache.ca/actualites/elections-municipales/resultats-officiels-aux-elections-municipales-2025, dated 2025-11-03, confirming the 2025-11-02 election): all 11 sitting members elected for Option Saint-Eustache – Équipe Marc Lamarre; the Mayor and 6 councillors (districts 2, 3, 4, 5, 6, 8) by acclamation. Official @saint-eustache.ca emails kept. Record-level election field left as the 2026 provincial election.
