Please note that the licences and permits shown in this map are authorized under the Aggregate Resources Act. These sites may not be actively extracting aggregate if there is no market demand for the type of aggregate being produced (e.g., to supply local infrastructure projects).

Sand, gravel and bedrock (i.e., aggregate) is found only where there are naturally occurring deposits and the quality and type varies considerably depending on the geology of the area. Some areas of the Province have large quantities of aggregate, while other areas have very little.

To identify any errors or issues with Pits and Quarries online, or if you need any of the information in an alternate format, please contact the Natural Resource Information and Support Centre.

For information on rules and compliance regarding a specific site, contact your local Ministry of Northern Development, Mines, Natural Resources and Forestry district office.
