electionsmanitoba.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. Band councils, municipal budgets and party control are left out; most councils sit without parties anyway.
- Election results. Where the page says “today’s boundaries”, it means Elections Canada’s estimate of the 2021 vote on the 2023 ridings; every other count is official and on the 2013 map.
