- Not on this page. The open files end at election night: no council votes since, and no band councils.
- Who holds each seat. Who holds each seat is read from Wikidata, so a very recent change in the Commons may not appear yet.
- Which riding. A riding is listed when 5% or more of the place’s 2021 Census residents live in it; the largest share comes first.
- 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.
- Council size. The 2021 Census population is shared over all council seats, including the head of council’s, for this ratio.
- Council money. Per resident uses MAMH’s population; the 2024 financial report gives charges by service and the financial profile the revenue, debt and reserves.
