When Chapman Mills votes
The last and next general elections at each level; a by-election can come in between.
| Election | Last | Next |
|---|---|---|
| Ottawa council | 26 October 2026 | 28 October 2030 |
| Legislative Assembly of Ontario | 27 February 2025 | – |
| House of Commons | 28 April 2025 | – |
No open copy of the 2025 counts exists, and Elections Canada’s own terms rule out commercial reuse, so 2021 is the last vote shown. The Legislative Assembly of Ontario was last elected on 27 February 2025, and the House of Commons on 28 April 2025. Councils are elected on the fourth Monday in October every four years, says the Municipal Elections Act, 1996, so Ottawa votes next on 28 October 2030.
