Well Decommissioning & Abandonment in Innisfil
Professional well decommissioning services for Innisfil homes, farms, and businesses.
Innisfil's rapid growth — among the fastest in Simcoe County — has generated a high volume of well decommissioning work. Properties that historically drew from private wells are being connected to municipal water as service extends. Former farmland is being developed into residential subdivisions, with severances and lot creations requiring old wells to be decommissioned. Lakefront properties along Lake Simcoe see steady turnover, with pre-purchase inspections regularly surfacing unsealed wells. Mighton's Well Services handles all of these scenarios with proper Reg. 903 compliance and prompt MECP record filing.

What to Expect for Well Decommissioning in Innisfil
When our team arrives at your property in Innisfil, here's how the process works. Learn more about our full well decommissioning process.
Site Assessment & Records Review
We start by pulling the Ontario Well Record for the property if one exists and reviewing the original construction details. On the site visit, we inspect the well, confirm depth and condition, and identify any obstacles such as a stuck pump, collapsed casing, or hidden access challenges. For old wells without records, we assess construction type in person.
Written Estimate & Scheduling
We provide a written estimate covering pump and equipment removal, sealing materials and labour, surface restoration, and MECP record filing. The estimate is firm unless we encounter unexpected conditions inside the well, in which case we contact you before any additional work. We schedule the work to fit both your timeline and the seasonal conditions at your property.
Pump & Equipment Removal
On work day, our service rig pulls the pump, drop pipe, safety rope, wiring, and any other equipment from the well. We disconnect the pitless adapter, pressure tank, and pressure switch and remove them from the site or set them aside for disposal as you prefer. The well is now ready for sealing.
Sealing & Casing Removal
We seal the well from the bottom up using the appropriate approved material — bentonite chips, bentonite grout, or cement-bentonite grout — placed in lifts to ensure continuous contact with the formation. Once the well is fully sealed to surface, the casing is cut at least one metre below grade and either pulled or capped. The surface is backfilled, graded, and restored.
MECP Record Filing & Documentation
We file the Well Decommissioning Record with the Ministry of the Environment within the regulated timeframe and provide you with a copy for your property file. This documentation is what real estate buyers, lenders, and severance applications will ask for — keep it with your other property records.
Common Well Decommissioning Issues in Innisfil
Subdivision development converting former Innisfil farmland
Residential subdivisions across Innisfil — particularly south and east of the original Town of Innisfil core — are being built on former farmland that often had multiple wells. These wells must be decommissioned before lot grading and construction, and developers need MECP records for planning approval.
We work with developers on subdivision-scale decommissioning projects, inventorying all wells on the parcel and decommissioning them as a coordinated package. Records are provided in a format suitable for planning department submission.
Lakefront properties with original wells from before municipal service
Older lakefront homes along Lake Simcoe in Innisfil sometimes still have original wells from before municipal service or before the current well was drilled. These often sit unsealed, posing contamination risks to the lakeshore aquifer and to neighbouring private wells.
We decommission former lakefront wells with appropriate technique for the shoreline location, ensuring no contamination pathway to the lake or surrounding wells. Surface restoration is handled carefully on manicured lakefront properties.
Municipal water connections triggering decommissioning requirements
As Innisfil municipal water service has been extended into formerly unserviced areas — Alcona, Stroud, Lefroy and beyond — homeowners who connect to town water often leave their original well in place. Reg. 903 requires that well to be decommissioned, and the municipality may require proof before issuing the service permit.
We coordinate decommissioning with the municipal connection schedule and provide records suitable for the municipal permit file. The work is typically completed in a single day with minimal disruption.
Check Subdivision Lots for Pre-Development Wells
If your Innisfil property is in a newer subdivision built on former farmland, do not assume all old wells were decommissioned during development. Records can be incomplete and some wells get missed. A property check using Ontario Well Records and on-site inspection takes a few hours and is far less costly than discovering an unsealed well during a future renovation or sale.
