Mississauga Building Permits – Open Data API

Building Permits for Mississauga only, from the city's official open dataset (~35,000 source rows), via the ArcGIS REST API — no website scraping.

• Key fields: permitNumber, permitType, workType, status, issuedDate, ward, estimatedValueCad, residentialUnits, storeys.
• Licence: City of Mississauga Open Data Terms of Use; every record carries the required credit and licence link.
• Output: structured JSON, or CSV / Excel from the Apify dataset. Filters run at the source (type, status, issued dates and more), up to 50,000 permits per run.
• Privacy: street addresses and free-text descriptions removed; postal codes cut to FSA and coordinates rounded to ~1 km where present.

Why not build it yourself? No ArcGIS/Socrata paging, field mapping, date normalising or de-duplication to write and maintain. You get one tidy row per permit with consistent field names and ISO dates.

Price: $0.003 per result (three-tenths of a cent; 1,000 results = $3.00), no start fee. You pay only for permits returned.

What it does

This Actor reads building permits from the City of Mississauga's official open dataset (Mississauga open data, about 35,000 source rows) through the ArcGIS REST query API. It does not scrape any website.

Rows are deduplicated so you get one record per permit number.

FAQ

Is this scraping? No. It queries the city's public ArcGIS REST API.

Does it include owner or applicant names or addresses? No. Street addresses, names and descriptions are removed, but the data is reduced, not anonymous: a permit number can be looked up in City records and may relate to a specific property.

Can I use it commercially? Yes, under the City of Mississauga Open Data Terms of Use. If you pass the data on, include the Terms URL. Don't imply City endorsement and don't use City logos or marks.
