Leasing to a Dry Cleaner or Auto Shop: Environmental Clauses for Commercial Landlords

A garage or dry-cleaning tenant changes what you are exposed to at every stage of the lease, from the day you sign to the day you sell. Here is what Ontario’s environmental rules say at each stage, and what you can do about it.

I’m Arthur Zhao, a real estate broker in Toronto. When a commercial owner tells me a dry cleaner or an auto repair operator wants their unit, the first conversation is usually about rent, term and the personal guarantee. The environmental conversation tends to come later, often only when someone asks for a clause at the drafting stage.

I think it is more useful to treat the environmental side as something that runs the full length of the lease. What you are exposed to before signing is different from what you are exposed to while the tenant operates, at move-out, and years later when you sell, refinance or redevelop. This article walks through those five stages in order. At each one I set out what the legislation actually says, and what a landlord can reasonably do about it, usually with a lawyer’s help. None of it is legal advice; the clause wording belongs to your lawyer.

Stage 1 — Before you sign: what will the tenant actually do on site?

The labels “dry cleaner” and “auto shop” cover a range of operations, and the regulation that matters most later on is precise about which ones count. O. Reg. 153/04 defines a garage as “a place or premises where motor vehicles are received for maintenance or repairs for compensation” (s.1). For dry cleaning, the regulation refers to “the operation of dry cleaning equipment” on the property. A drop-off counter that sends garments to a plant elsewhere is a different fact pattern from a unit with cleaning machines on the floor, so the first job is to find out which one you are being asked to lease to.

Your legal exposure at this stage is not zero just because nothing has happened yet. Section 18 of the Environmental Protection Act lets the Director, by written order, require “a person who owns or owned or who has or had management or control of an undertaking or property” to take preventive steps, such as installing equipment, implementing procedures, monitoring and reporting, or developing spill-prevention plans. The Director has to be of the opinion, on reasonable and probable grounds, that the steps are necessary or advisable to prevent or reduce the risk of a discharge or an adverse effect (s.18(2)). Whether an order is ever made, and to whom, is the Director’s discretion, but the property owner is on the list of possible recipients.

Practical questions worth asking before you commit: What equipment will be installed, and where? What will be stored on site, and in what quantities? Has the operator run this kind of business elsewhere, and can they show you how they handle waste? Is there a floor drain, a sump, or anything else in the unit that connects to the outside? You are not trying to become an engineer; you are deciding whether you understand the operation well enough to put a price on it.

Stage 2 — Drafting the lease: clause types to discuss with your lawyer

A lease cannot change who the Environmental Protection Act allows the Director to order. The provisions discussed in this article name categories of people such as owners, occupants and persons in control; none of them refers to what a lease says. What a lease can do is allocate cost and information between you and the tenant, and give you the tools to find out what is happening in your unit. These are the clause types I would expect a landlord’s lawyer to consider for this kind of tenant:

• A narrow permitted-use clause that describes the actual operation, so the tenant cannot quietly expand from drop-off to on-site cleaning, or from tire storage to full repair work, without your consent.
• Hazardous substances disclosure: a list of what the tenant may bring on site, with an obligation to update it.
• Compliance with environmental laws, including any approvals the tenant’s operation needs, with copies to the landlord.
• Notice to the landlord of any spill, any report to the Ministry, and any order or inspection, within a short fixed time.
• Inspection and testing access, including the right to retain your own consultant.
• An environmental indemnity from the tenant, and from a guarantor where there is one, that is drafted to survive the end of the lease. The related article on environmental indemnities in purchase agreements covers how these are typically framed.
• Insurance requirements; the related article on pollution liability insurance covers what ordinary policies may not respond to.
• Restoration and removal obligations at the end of the term, including equipment, tanks and waste.
• Assignment and sublease controls, so a new operator cannot step in without the same scrutiny.

Some landlords also ask for an environmental assessment at the start of the term, to be compared with another at the end. I could not find any Ontario law that requires this for a lease; it is a practical arrangement that parties agree to, not a statutory step. Whether it is worth the cost for your unit is a question for your lawyer and an environmental consultant.

Stage 3 — During the term: who must report a spill, and who does not

If something is spilled, according to the Environmental Protection Act (Government of Ontario e-Laws, 2026), section 92(1) requires “every person having control of a pollutant that is spilled and every person who spills or causes or permits a spill” to notify the Ministry and the municipality forthwith. The list of people who must be notified includes the Ministry, the municipality, and in some cases the owner of the pollutant or the person in control of it. The owner of the building is not on that list. In other words, a tenant could meet its statutory reporting duty without the landlord ever hearing about it. That is the practical reason the notice clause in Stage 2 matters.

Section 93(1) then puts a clean-up duty on “the owner of a pollutant and the person having control of a pollutant that is spilled.” It is easy to misread this as a duty on the property owner. It is not. Under s.91, the “owner of the pollutant” means the owner of the pollutant immediately before the first discharge. For solvents or fluids bought and used by the tenant’s business, that will ordinarily point to the tenant, though how it applies to any real spill is a question for a lawyer.

Separately, section 17 allows the Director to order a person who “causes or permits” a discharge that injures or endangers land, water, property, life or health to repair or prevent the damage. Whether a landlord could be said to have permitted anything is fact-specific, and I am not going to guess at it; the point is that the order powers are discretionary and fact-dependent, not automatic in either direction.

Day to day, what helps is routine: use your inspection right, keep the tenant’s updated substance list and any reports in your files, and follow up promptly if anything changes in the operation.

Stage 4 — At lease end: what can be left behind

Move-out is where environmental risk most often turns into a real cost, because it is the point at which the tenant’s incentive to cooperate drops. Equipment, containers and waste left in a unit are not only a nuisance. Section 43 of the Act allows the Director, where waste has been deposited in any building that has not been approved as a waste disposal site, to order its removal and the restoration of the site by, among others, “an owner or previous owner” of the land or building, or “an occupant or previous occupant.” Both you and the departing tenant are within that wording; who actually receives an order is the Director’s call.

This is where the restoration clause and the surviving indemnity from Stage 2 earn their keep. Practical steps at this stage: schedule a walk-through well before the last day; check the unit against the substance list and equipment inventory you have kept; make sure removal is done before you take the keys back and release any deposit; and, if you agreed to an end-of-term assessment, have it done while the tenant is still accountable under the lease. Again, an exit assessment is a contractual and practical choice, not something the legislation imposes on a lease ending.

Stage 5 — When you sell, refinance or change the use

Ontario does not require a Record of Site Condition simply because a property is leased, sold or refinanced. The trigger in the Act is a change of use. Section 168.3.1(1) prohibits changing a property from industrial or commercial use to residential or parkland use, or in another manner prescribed by regulation, unless a Record of Site Condition has been filed for the new use. The regulation adds other prescribed changes; for example, O. Reg. 153/04 s.14 para. 4 lists a change from commercial use to an agricultural or other use or to an institutional use. A Record of Site Condition requires a qualified person to certify that a Phase One environmental site assessment was done and, where required, a Phase Two (EPA s.168.4).

This is where your earlier tenant comes back into the picture. According to O. Reg. 153/04 (Government of Ontario e-Laws, 2026), because the property “has ever been used” as a garage or for dry cleaning equipment, a Phase Two assessment is required for an RSC filing under s.32(1)(b), whoever owns the property by then. And the upper-floor residential exemption in s.15(1) para. 2, which can let a commercial building add residential use above the ground floor without an RSC, is unavailable once the property has that history.

Buyers and lenders do their own due diligence, and the questions they ask are outside these rules. Whatever they ask, the use history is a fact about the property, so the paperwork you kept during the lease (permitted-use wording, substance lists, notices, any assessments) is what lets you answer clearly. The related article on environmental due diligence before buying shows what the other side of the table tends to look for.
