This data set can be used to identify areas that are designated under the Aggregate Resources Act of Ontario. Designated area determines what rules have to be followed for a pit and/or quarry. It also determines together with private and Crown land, if an Aggregate Permit or an Aggregate License is required. In the act the area is described in lower tier townships, upper tier townships, single tier townships and geographical townships, depending upon what was available at the time of designation.
Supplementary tables can be used and are available for download from the additional documentation section.
