- Council size. Residents per seat divide the 2021 Census population by every council seat, the head of council’s included.
- Council money. Spending by service comes from MAMH’s consolidated 2024 financial report, revenue, debt and reserves from its financial profile, all per resident on MAMH’s population.
- Who holds each seat. A member who resigned or switched parties last week may still show here: the names are Wikidata’s.
- Not on this page. The open files end at election night: no council votes since, and no band councils.
- 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.
- Which riding. A place belongs to the riding where most of its 2021 Census residents live, plus any other with 5% or more.
