Zoning API
Zoning districts for 44 Canadian cities as polygons, with zone code, description, and land-use category. Resolve the zoning classification at any coordinate, or list every zone in a city, through one REST API.
Zoning districts are sourced from municipal open data portals as polygon layers and stored as geometry. Coverage spans 44 cities across 7 provinces, with the zone code, description, and land-use category preserved as published.
What the data includes
Who uses zoning data
Development feasibility
Resolve the zone for any parcel before acquisition. Combine zoning with permit and assessment data to gauge what can be built and what is being built nearby.
Site selection
Filter candidate sites by zoning category across a city. Find commercially-zoned land near residential growth, or industrial land along transport corridors.
Proptech & due diligence
Attach the zoning classification to any address in a listing or portfolio. Flag zoning mismatches and overlay districts during underwriting.
GIS & analytics
One consistent zone-code schema across 44 cities, instead of 44 different municipal layers. Look up by coordinate or pull a city's full zoning schedule.
API example
