Ontario Road Network with Official Names and Attributes

A provincewide geographic database contains over 250,000 kilometres of municipal roads, provincial highways, and resource roads. The Government of Ontario maintains this authoritative source, which was last updated in March 2026. It includes official street names, classifications, and attributes like speed limits and number of lanes.

Use Cases

• Analyze road classification and number of lanes to model traffic capacity and plan infrastructure upgrades.
• Map official street name and alternate street name fields for address validation and geocoding services.
• Use road surface and speed limit attributes for vehicle routing algorithms and fuel consumption estimates.
• Query jurisdiction and source tables to audit data provenance and authority for specific road segments.
• Identify blocked passage and underpass features for emergency response planning and accessibility analysis.

Strengths

• Contains over 250,000 kilometres of road data across the entire province.
• Serves as the authoritative source of roads data for the Government of Ontario.
