- Who holds each seat. MPs come from Wikidata’s records of the 45th Parliament, which can lag a resignation or a by-election by some days.
- Which riding. Each place is put in its ridings by where its 2021 Census residents live; a riding holding 5% or more of them is listed.
- Election results. The 2019 and 2021 figures are Elections Canada’s official counts on the ridings drawn in 2013; the “today’s boundaries” figures are its transposition of the 2021 vote onto the 2023 ridings, an estimate built from polling divisions.
- Not on this page. No council budgets, no band councils, and no party tally for the council, which the open lists don’t record.
