- Not on this page. Party control (most Canadian councils sit without parties, and the open lists record none) and band councils.
- Who holds each seat. A member who resigned or switched parties last week may still show here: the names are Wikidata’s.
- Which riding. Ridings are assigned from the 2021 Census: the one with most residents first, then any holding 5% or more.
- 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.
- Council size. The council size includes the head of council; the population is the 2021 Census, the whole city’s for a neighbourhood.
- Council money. Per resident means the 2024 Financial Information Return’s totals over the population it reports. Since a county or region spends in its lower tiers too, those are compared only with each other.
