Sources and methodology

Records	Latest date included	Meaning
Council votes	Oct 27, 2026	Latest meeting with a recorded vote in this snapshot.
Office spending	Jun 30, 2026	Latest reporting period end; coverage varies by office.

These are dates in the saved records, not a live feed or a guarantee of complete coverage. Rebuilding the database does not refresh the source snapshots.

This is a curated selection, not a complete catalogue of positions or decisions. Related budget choices share a score weight. Named public-hearing roll calls supplement the electronic snapshot where verified. Unrecorded individual votes remain unknown, including unnamed supporters of the 2024 rezoning final reading. Review dates establish when curation was checked, not the date of a new official record.

Candidates' final statements for each election (2025 candidates file one per calendar year). Checked by OCR: every arithmetic identity on the form holds as read. Transcribed: a reviewer read the totals from the scan (mayoral front-runners, council winners, and every statement OCR could not fully check) and they hold, leaving out lines a form contradicts. Partly checked: the identities that could be tested hold, others are blank. Unchecked: an identity fails, so at least one total is misread. Misread: the totals as read cannot all be true (a part larger than the whole, revenue and spending more than tenfold apart, or a sum beyond any Calgary campaign), so they are not shown. Not read: OCR could not read the form. Party and third-party statements are not counted here: all of their final statements were transcribed in full, totals and listings.

Listing captures: readable listed contributions as a share of the form's own itemized total, median across statements. Below 100% means rows or amounts on the attached listing were not read, so contributor totals understate what was given.

Election results

Elections

Election	Station sums match totals	Voting stations	Ward electors	Note
2010	Not applicable	0	Eligible electors in the City's April 2010 civic census	Official totals by ward only. Electors and ward boundaries come from the City's 2010 civic census.
2013	86 of 94	611	Official enumerated electors by ward	The station file omits some stations; candidate totals come from the official summary.
Apr 13, 2015 by-election	Not applicable	0	–	Official totals only.
2017	128 of 128	717	Estimated: city electors apportioned by official ward elector shares

City-wide turnout is official in every year except 2010, which is estimated from mayoral votes and the 2010 civic census count of eligible electors. Ward electors are official for 2013, from the civic census for 2010, and estimated for the other years.
