In London, Ontario, purchasing a commercial property without conducting a Phase 1 Environmental Site Assessment (ESA) can make you personally liable for millions of dollars in pre-existing soil and groundwater contamination. A proper ESA protects you under the Ontario Environmental Protection Act and is strictly required by almost every Canadian bank before they will approve a commercial mortgage.
Purchasing commercial real estate in London, Ontario, is a massive financial milestone. 🏬 Whether you are looking at an old manufacturing warehouse in East London or a retail plaza in the downtown core, the physical building is only part of the investment. What lies beneath the soil can dictate whether the property is a goldmine or a financial disaster.
Because London has a rich industrial history, many properties hide invisible dangers like chemical spills, old underground oil tanks, or asbestos. If you buy a contaminated property, the Ontario Ministry of the Environment, Conservation and Parks can legally force you to clean it up, even if you did not cause the pollution. In this guide, we will break down how to review an Environmental Site Assessment (ESA) so you can protect your business and your wallet.
Step-by-Step Process for Conducting an ESA in London, Ontario
An Environmental Site Assessment is not a simple home inspection. 🔍 It is a rigorously structured scientific process mandated by provincial regulations to uncover historical and current environmental liabilities.
Step 1: Ordering a Phase 1 Environmental Site Assessment
The first step is hiring a qualified environmental consultant to conduct a Phase 1 ESA. During this phase, no drilling or testing occurs. The consultant will visit the London property, review historical city directories, check aerial photographs, and investigate whether the site was ever used as a gas station, dry cleaner, or industrial plant.
Step 2: Reviewing the Phase 1 Report with Your Lawyer
Once the report is finished, your corporate real estate lawyer must review it. 📝 If the consultant finds zero evidence of potential contamination, the process stops here, and your bank will usually clear your financing. However, if the report flags “Areas of Potential Environmental Concern” (APECs), you will be legally advised not to close the deal until further testing is done.
Step 3: Proceeding to a Phase 2 ESA
If the Phase 1 report raises red flags, you must order a Phase 2 ESA. This involves bringing heavy drilling equipment onto the property to extract soil and groundwater samples. These samples are sent to a laboratory to determine the exact concentration of toxic chemicals present beneath the concrete.
Step 4: Remediation and Filing a Record of Site Condition
If contamination is found, the soil must be cleaned up (remediated) before the property can be developed, especially if you are rezoning it from industrial to residential use. 🚜 Once the cleanup is complete, a Record of Site Condition (RSC) must be formally filed with the Ontario government, proving the land is now safe.
How Much Does an Environmental Site Assessment Cost in London?
Environmental due diligence is expensive, but skipping it is financially reckless. 💵 Generally, the buyer is responsible for paying these costs during the conditional period of the real estate transaction.
- Phase 1 ESA: A standard historical review by an engineering firm typically costs between $2,500 CAD and $4,500 CAD.
- Phase 2 ESA: Because it involves drilling and lab work, a Phase 2 usually ranges from $10,000 CAD to $25,000 CAD, depending on the size of the London property.
- Legal Review Fees: Having your law firm review the ESA reports and draft protective indemnification clauses usually adds $500 CAD to $1,500 CAD to your closing costs.
| ESA Phase | Estimated Cost (CAD) | What is Included? |
|---|---|---|
| Phase 1 ESA | $2,500 – $4,500 | Historical research, visual site inspection, report |
| Phase 2 ESA | $10,000 – $25,000+ | Borehole drilling, soil & groundwater lab testing |
| Phase 3 (Remediation) | $50,000 – $1M+ | Removing toxic soil, replacing with clean fill |
How Long Does the Process Take?
You must ensure your Agreement of Purchase and Sale includes a long enough “due diligence” condition. A Phase 1 ESA typically takes 3 to 4 weeks to complete. If a Phase 2 ESA is required, booking the drilling equipment and waiting for lab results will add another 4 to 8 weeks. Therefore, commercial real estate closings in London often require 60 to 90 days just to clear environmental conditions.
Frequently Asked Questions (FAQ)
Can I skip the ESA if I am paying cash for the property?
Legally, yes, if you do not need bank financing, you can waive the ESA. However, doing so means you assume 100% of the liability. If the province later discovers contamination leaching into the Thames River from your land, you will pay millions in cleanup costs out of pocket.
Can the seller be forced to pay for the Phase 2 testing?
Everything is negotiable. If a Phase 1 reveals risks, your lawyer can negotiate with the seller’s lawyer, asking the seller to either pay for the Phase 2 testing or significantly drop the purchase price to offset your risk.
What is an “As Is, Where Is” clause?
Many commercial properties in London are sold “As Is, Where Is.” This means the seller guarantees nothing about the environmental state of the building. If you buy it and find oil tanks buried in the back, you cannot easily sue the seller later.
Do I need an ESA if I am just leasing the building?
It is highly recommended. Some commercial leases make the tenant responsible for environmental cleanups at the end of the lease. A baseline ESA proves you did not cause the contamination during your tenancy.
