How can I find recorded pits, quarries and petroleum wells near a Greater Sudbury home?

The Province's Find Pits and Quarries map shows the sites licensed or permitted under the Aggregate Resources Act, including aggregate permits and wayside permits, and can count the sites near a point you choose. The Province says a pit on private land in a part of Ontario not regulated under the Act may not appear; Ontario Regulation 244/97 designates all of the former Regional Municipality of Sudbury, and seven more geographic townships now in the City, among the regulated parts. A licence on the map doesn't mean a site is digging today, and a newly approved site can take time to appear.

The map covers aggregate, that is sand, gravel and bedrock, pits and quarries; it is not a map of mines. The petroleum wells dataset records the location of wells drilled for oil or gas, for salt, or for storing hydrocarbons underground. Both are records of what was licensed or drilled, not a history of every use of a piece of land: a blank result is not proof that land was never a pit, a dump or an industrial site.

Past land use nearby runs for any Ontario address. The free check measures the distance to the nearest mapped aggregate site and petroleum well on the spot. The full report adds waste management sites and federal contaminated sites to the same group. None of it is a soil test or an environmental site assessment.
