Aggregate Site Authorized

This dataset represents the locations of licenced and permitted pits and quarries regulated by the Ministry of Natural Resources and Forestry under the Aggregate Resources Act, R.S.O. 1990.

Aggregate site data has been divided into active and inactive sites. Active sites may be further subdivided into partial surrenders. In partial surrenders, defined areas of a site are inactive while the rest of the site remains active.

The data includes:

  • site location and size
  • licensee name
  • approval type (licence or permit)
  • operation type (pit or quarry)
  • maximum annual tonnage limit
  • the MNRF district responsible for the site

Use our interactive pits and quarries map to find active sites.

This data does not include aggregate sites regulated by the Ministry of Transportation.
