Ontario Address Change Tracker

We periodically compare each municipality's official open address list to spot new buildings, retired addresses, and corrections over time.

81 datasets 6.4M address records updated daily Source on GitHub ↗ i How it works

Every day each dataset is re-downloaded and diffed against the previous snapshot. History is kept as a Slowly-Changing-Dimension Type-2 table, so every address records the span of snapshots it was valid for — letting us replay exactly when an address first appeared, was corrected, or retired.

The hard part is identity: ESRI OBJECTIDs are reassigned on every republish, so records are matched on a stable source ID where one exists, or on a synthesized key (street + number + unit + rounded coordinates) otherwise. Adding a city is a config file, not code.

An independent civic-data project — not affiliated with any municipality. Each source keeps its own open licence.

6 sources probed but not added
City of Belleville
gis.city.belleville.on.ca services root is empty (and its TLS cert is broken). Re-probed 2026-08-20 and 2026-10-30: the city's AGOL org (BellevilleGIS, 71 public services, hub 70 datasets) has no address layer - its Parcels carry ROLL/ParcelID only - and Hastings County's CivicAddresses excludes the separated city (no MUNICIPALI code for Belleville).
Dead endpoint
Northumberland County
Re-probed 2026-08-20 and 2026-10-30: the server is back (moved /arcgis to /server, 46 services) and the AGOL org has 199 more, but no address points anywhere - the only civic-address layer is 421 road polylines from 2019, and Parcel_Fabric_2025 (6,437 polygons with STREET_NUM/STREET_NAM) is one lower tier's fabric, a weak fallback at best. Cobourg (tracked, gated) covers part of the county.
No address layer
Essex County
Re-probed 2026-10-30: still no county-wide points (hub 120 datasets, cwserver OpenData 5 services). The county AGOL org does hold a Kingsville layer, MESH_WFL1/FeatureServer/0 'KingAddress_Sep25' (10,270 points, CIVIC/HOUSE_NO/STREET, owner rpalmini_kingsville, last edited 2025-10-28, no licence) - a dated snapshot inside a staff working map, tracked as kingsville from 2026-10-30, gated. Amherstburg, Tecumseh, Leamington and Kingsville are tracked; LaSalle, Lakeshore, Essex and Pelee have nothing.
No address layer
Owen Sound
Re-probed 2026-10-30: the city org (48 services) still has no address points; Parcels (8,072 polygons, 2024-02) carries address1-3 as a weak fallback. Grey County's tracked parcel-label layer already holds ~6,770 Owen Sound rows (city spelt five ways), so the city is covered from the county side.
No address layer
Kenora
Re-probed 2026-08-20 and 2026-10-30: city AGOL org is live (13 public services - zoning, roads, ownership, trails) but publishes no address or parcel-address layer.
No address layer
City of Brockville
Found by the ontario-osm-data-sources sweep (8,796 civic address points, last updated 2017). Probed 2026-10-16 and 2026-10-30: the PSDCitywide services, the PublicOnly folder and the layer count all answer 499 Token Required, and the city AGOL org (37 services) has roads only. The tracked United Counties of Leeds and Grenville layer carries 8,737 City of Brockville points (MUN = 'CITY OF BROCKVILLE', edited 2026-10-06, OGL), so the city is already covered from the county side.
