Ontario well records are public records that can help you find an existing well, review its recorded depth and construction, and understand nearby groundwater context. Start with the property address, compare the closest mapped records, then verify the correct record in Ontario's official Well Record Map before relying on it.
Use this address-first record search to identify candidate records, then follow the step-by-step guide to find your well on the property using well tags, seller documents and physical evidence.
Search Ontario well records around a property
Ontario has a large public database of water-well records. The official provincial map is valuable when you already know which well you want to inspect. Check My Well is built around a different starting point: an address.
Search the property first and Check My Well organizes available mapped records around it, sorts nearby wells by distance and summarizes useful fields so you can understand the local pattern before opening records one by one.

Find well records by address →How to find a well record in Ontario by address
- Enter the property address. Start with the civic address you want to investigate.
- Review nearby mapped wells. Compare the closest available records instead of assuming the first pin is the property's well.
- Compare depth and water information. Look for patterns in recorded depth, construction and reported pumping-test data.
- Open the source record. Verify any important finding against the official Ontario record before relying on it for a purchase, repair or drilling decision.
Ontario well records map: how to use the official Well Record Map
If you are searching for an Ontario well records map, the province's official tool is called the Ontario Well Record Map. It is the public mapping tool for locating and opening well records. It is the authoritative place to verify a specific record. Check My Well does not replace that source; it makes the first stage easier by organizing nearby mapped records around the property address.
If a search produces several wells close together, use the provincial map and record details to distinguish them. Location, construction date, depth, well tag information and other fields can help determine which record deserves closer review.
MOE well records and the Ontario well map
If you searched for MOE well records, MOE well map or Ministry of Environment well records, you are looking for Ontario’s provincial well-record information. The current public Well Record Map lets you locate and open mapped source records; Check My Well adds an address-first view for comparing nearby records before you verify the one that matters.
The provincial record remains the source to verify. A nearby map point alone does not prove that the well belongs to the searched property.
Can I find well depth records by address?
Often, yes. An address search can surface nearby Ontario well records that contain recorded total depth. That is useful when you are trying to understand whether wells around a property tend to be shallow, deep or highly variable.
The key limitation is attribution: a depth attached to the nearest mapped well is not automatically the depth of the well on the property. Use the address to find the local records, then verify the correct record before treating its depth as property-specific.
What an Ontario well record can tell you
The Ontario government says well records are used to find existing wells, understand groundwater and geology in an area, and preserve original construction information. Depending on the record, useful fields can include:
- Mapped well location and identifying information
- Well depth and construction details
- Completion or construction date where reported
- Casing, screen and formation information
- Static water level where recorded
- Pumping-test results and reported well production or yield
- General groundwater or water-quality information recorded at the time
Not every record contains every field, and historical records can vary in completeness.
Ontario private well records: what is public?
Ontario well records are public provincial records for reported wells. They can contain location and construction information, but a historical record does not prove current well condition, current water quality or that a nearby mapped record serves a specific property. Use the public record as evidence to match and verify—not as an automatic property assignment.
Well tags and Ontario well records
A well tag is a unique identifier used to link a physical well with its well record. If you can safely locate the well tag on the property, it can be extremely useful when confirming that a record belongs to the well you are investigating.
If you are buying a rural home and the seller has a copy of the original well record, compare the well tag, construction details and location with the information you find online. If you are trying to locate the physical well itself, use the step-by-step guide to find your well on the property.
Why the nearest mapped well may not be your well
This is one of the most important limitations of any Ontario well-record search. Older mapped locations can be approximate, properties can be severed or combined, and multiple wells may exist close together. A pin beside a house is not automatically proof that the record belongs to that address.
That is why Check My Well uses wording such as nearest mapped record and shows nearby records as context rather than silently assigning a well to a property.
What nearby Ontario well records are useful for
One record can tell you about one recorded well. A group of nearby records can help you understand the local pattern. That can be useful for:
- Buying a rural property: identify questions to ask the seller, inspector or well contractor.
- Planning a new well: see the range of nearby recorded depths before requesting drilling quotes.
- Investigating an existing well: compare construction and groundwater information from nearby records.
- Estimating project costs: use local depth context with the well drilling cost calculator.
- Preparing for an inspection: bring relevant records to a well inspection or contractor visit.
Buying a house with a well in Ontario
A well record is useful due-diligence information, but it is not a substitute for checking the current system. A historical record cannot confirm today's pump condition, pressure system, bacteria results, water chemistry or actual current yield.
Before a major purchase decision, consider the record together with current well water testing, a physical inspection and advice from a qualified local professional where appropriate.
How do I find a well on my property?
Start with the civic address and compare the nearest mapped well records rather than relying on one pin. Look for supporting details such as a well tag, drilling date, depth, construction information and location, then open the original Ontario record to verify the likely match. If the online record is unclear, physical well identification and help from the provincial source or a qualified local professional may be needed.
What if no Ontario well record appears for the property?
Do not assume that no record means no well. The Ontario government states that its well-record data extends from 1899 to the present, but older records may have location limitations and some searches require additional investigation.
Try reviewing a wider group of nearby mapped records, look for a visible well tag or documentation from the owner, use the property well-location guide, and check Ontario's official Well Record Map. If a record still cannot be located, the Ministry provides a process for requesting help finding an individual record.
Ontario well records vs. Check My Well
The Ontario government remains the source of record. Check My Well does not replace the provincial database. It adds an address-first property view that makes it easier to compare nearby records, spot local depth patterns and decide which official records deserve a closer look.

Frequently asked questions
Can I search Ontario well records by address?
Yes. Check My Well starts with a property address and analyzes mapped Ontario well records nearby. Because some older mapped locations can be approximate, the nearest mapped record is not automatically proof that it belongs to the property.
Can I find well depth records by address in Ontario?
Often. Start with the property address, review nearby mapped Ontario well records and compare the recorded total depths. A nearby record provides context but should not be silently assigned to the property without supporting evidence.
Where can I find the Ontario well records map?
Ontario's official provincial tool is called the Ontario Well Record Map. It lets you locate and open well records on a map. Check My Well adds an address-first view for comparing nearby mapped records before you verify a specific record at the provincial source.
What information is in an Ontario well record?
Ontario well records can include the well location, construction details, depth, completion information, pumping-test results, groundwater information and other fields reported when the record was created.
Are Ontario well records free?
Yes. Ontario's underlying provincial well records are public, and the basic Check My Well property lookup is free.
How far back do Ontario well records go?
The Ontario government states that its well-record data extends from 1899 to the present.
What if I cannot find a well record for my Ontario property?
A missing nearby match does not prove that a property has no well. Older records may have approximate locations or incomplete information. Check the official Ontario Well Record Map and contact the Ministry if necessary.
Can nearby well records predict my exact well depth or water quality?
No. Nearby records provide useful local context, but groundwater conditions, geology, well construction and water quality can vary between properties.
