What do Ontario's well records show?
Ontario's Water Well Information System holds the records that licensed well contractors file when they drill, deepen or abandon a well: location, depth, what the drill went through, and the water found. The check looks for records within 250 m of the address.

What the record is
The record is filed by the contractor, so it exists for wells drilled under the licensing rules and may be missing for older or unlicensed work. Locations in older records can be approximate. The Ministry of the Environment, Conservation and Parks publishes the system as open data.
The report line counts the well records within 250 m and, when there are any, gives the nearest one's depth, year and use. For a home on a private well it is the record of the well itself; for a home on municipal water it shows what the neighbourhood's wells found.
