What the record shows
The Province's Find Pits and Quarries map shows sites licensed or permitted under the Aggregate Resources Act and can count the sites near a point you choose. For a Grimsby home the useful number is the distance to the nearest licensed site. A licence on the map doesn't mean a site is digging today, and a newly approved site can take time to appear.
The petroleum wells dataset records wells drilled for oil or gas, for salt, or for storing hydrocarbons underground, across Ontario. 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 a Grimsby lot was never a pit, a dump or a factory.
