Licensed Aggregate Pit and Quarry Locations in Ontario

Ontario's Ministry of Natural Resources and Forestry provides data on licensed and permitted pits and quarries regulated under the Aggregate Resources Act. The dataset includes site location, size, licensee name, approval type, operation type, maximum annual tonnage limit, and responsible MNRF district, distinguishing between active and inactive sites. It was last updated in March 2026.

Use Cases

• Analyze spatial distribution of pit versus quarry operation types across Ontario districts.
• Assess regional aggregate production capacity by aggregating maximum annual tonnage limits per MNRF district.
• Track changes in land use by comparing active and inactive site statuses over time.
• Identify licensees holding multiple permits by joining records on the licensee name field.

Strengths

• Data distinguishes between active and inactive sites, including partial surrenders.
• Includes multiple regulatory attributes like approval type and maximum annual tonnage limit.
• Managed and updated by the authoritative government ministry (MNRF).

Limitations

• Excludes aggregate sites regulated by the Ministry of Transportation, limiting completeness.
• Sample data and specific row counts are unavailable for assessing dataset scale.
• Unknown temporal coverage for historical analysis of site status changes.
