electionsnb.ca ↗What this data can and can’t tell you
- Which riding. Ridings are assigned from the 2021 Census: the one with most residents first, then any holding 5% or more.
- Who holds each seat. Wikidata, edited by volunteers, is the source for each MP, and it can trail a change of seat by a little.
- Not on this page. Council budgets, band councils, and which party runs the council: the open lists carry no party, and most councils have none.
- Election results. Elections Canada redrew the ridings in 2023 and re-tallied the 2021 ballots onto the new map from polling divisions; that estimate, and the official 2019 and 2021 counts on the old map, are what you see.
