The Legislative Assembly of New Brunswick’s ridings aren’t published as open data we could find, so Saint-Isidore isn’t placed in one. For local government, Saint-Isidore is a parish. No open list of councils exists in New Brunswick, so no mayor of Saint-Isidore is named here. Across New Brunswick, 6 of the 10 MPs sit with the Liberal Party of Canada.

electionsnb.ca ↗What this data can and can’t tell you
- Which riding. A place belongs to the riding where most of its 2021 Census residents live, plus any other with 5% or more.
- Who holds each seat. Each MP’s name and party are Wikidata’s statements for the 45th Parliament, read in November 2026.
- Not on this page. Who controls the council by party (the open lists give none, and most Canadian councils sit without parties), budgets and band councils.
- Election results. Official counts for 2019 and 2021 are by the 2013 ridings; Elections Canada also re-counted the 2021 ballots onto the 2023 ridings by polling division, and that estimate is what “today’s boundaries” means here.
