# BuildData — Canadian Construction Records (Sample)
**Sample of 5,000 Canadian municipal construction records across 54 cities.**
Mix of building permits, business licences, development permits, planning
applications, and inspections. Last 3 months of data from the full
[BuildData API](https://builddata.ca).
> **Want the full dataset?** 8.6M+ records across 60 cities, normalized + geocoded,
> daily refresh, query by city / address / value / type / date.
> **[Get an API key →](https://builddata.ca/pricing)**
## What's in here
| Field | Type | Description |
|---|---|---|
| `source_id` | string | Originating system (city's open-data portal) |
| `entity_type` | string | `permit`, `licence`, `development_permit`, `planning_application`, `inspection` |
| `record_id` | string | Stable per-record identifier from the source |
| `municipality` | string | City name |
| `event_date` | string (ISO date) | Issue date for permits/licences, application date for planning |
| `category` | string | Permit type / licence type / planning stage |
| `data` | object | Full raw record from the source (JSON) — addresses, values, descriptions, GIS data |
## Composition (sample)
| entity_type | rows |
|---|---|
| permit | 2,500 |
| licence | 700 |
| development_permit | 700 |
| planning_application | 700 |
| inspection | 400 |
54 unique municipalities represented. The full dataset spans 60 cities including
Toronto, Montréal, Vancouver, Calgary, Edmonton, Ottawa, Winnipeg, Québec City,
Halifax, Saint John, plus 50 more.
## Use cases
- **RAG / agents** — ground LLM responses in real Canadian construction activity
- **Domain fine-tuning** — train models on construction vocabulary, NOC codes, GIS schemas
- **Real-estate intelligence** — track building permits as a leading indicator of property changes
- **Construction lead generation** — discover contractors, developers, suppliers active in a market
- **Insurance underwriting** — property age, renovation history, code compliance signals
- **Schema exploration** before committing to API integration
## Limitations of this sample
- **Snapshot only** — frozen 2026-02-25 to 2026-05-25. New permits issued daily; this sample will not reflect them.
- **5K rows** — full dataset is 8.6M+. Sample is enough to test schema, prompts, prototypes; not enough for production analytics.
- **No querying** — can't filter by city, value range, address, or date. Use the API for that.
- **No geocoded coordinates surfaced** — the full API returns `latitude`/`longitude`; sample omits them to keep payload small (still inside `data` for some sources).
