Data sources and methodology

This page explains where public datasets come from, how PoliticalData.ca uses them, and what quality limits apply. Bill summaries, representative profiles, votes, municipal finance pages, and economic indicators link back to official public records wherever possible.

Bill data and plain-English summaries

Federal bill data comes from Parliament of Canada sources such as LEGISinfo and House of Commons vote feeds. Provincial bill data comes from official legislature sources where machine-readable or synced records are available. Plain-English summaries are based on official bill text, official legislative summaries, published status data, and reviewed AI-assisted summaries when available.

PoliticalData.ca aims never to display estimated or placeholder values without labeling them. If a source does not publish a field, pages show that the detail is unavailable rather than guessing.

Representatives and votes

Representative lookup uses public civic boundary and representative data, then connects that context to bill sponsorships and recorded votes when the official bill source publishes representative-level records.

Address and postal-code lookup text is not placed in metadata, canonical URLs, or sitemaps.

Economy methodology

Economic scorecards use official source releases and term-aware attribution. Monthly, quarterly, and annual reference periods are attributed to the office window containing the period midpoint.

These figures describe economic conditions during a government term; they are not claims of sole political causation.

Ontario municipal FIR

FIR data is published by Ontario and reports municipal financial schedules by municipality, year, and SLC identifier. Raw source files are stored privately in Supabase Storage before parsing into normalized public tables.

FIR CSV by year FIR by schedule
Ontario municipalities can be lower-tier, upper-tier, or single-tier. Aggregating lower-tier and upper-tier municipalities together can double count some financial activity. Comparisons should be made carefully, preferably within comparable tier/type groups.

Available FIR years

Counts show official FIR returns available in each year's bulk file, out of 444 tracked Ontario municipalities.

Metric mapping health

Public cards use database-driven FIR SLC mappings. If a mapping is missing or ambiguous, the site keeps raw statement rows visible and avoids showing guessed summary values.

No mapping gaps are currently reported.

Neutrality and legal note

PoliticalData.ca is neutral civic information. Plain-English summaries are intended to help readers understand official records; they are not legal advice and do not replace the official source.
