How to Buy a Gas Station in Ontario: TSSA, Environmental Risk and Valuation

To buy a gas station in Ontario, a buyer needs to look well beyond the station’s sales: the underground fuel tanks and their regulatory status, the environmental history of the site, the fuel supply and branding agreement, the split between fuel and convenience-store earnings, and the difference between the real estate and the business. Gas stations are among the most heavily regulated and environmentally sensitive commercial properties, and the environmental and tank-related risks can outweigh the operating profit. This guide is for operators, investors and multi-site owners considering a gas station or gas station with convenience store in the GTA and Southern Ontario. It covers what to analyze, the regulatory and environmental issues specific to fuel sites, financing, acquisition costs and the mistakes that most often hurt buyers.

What You Are Buying

A gas station purchase can include several distinct pieces:

• The real estate: land and building, including the canopy, fuel island and any associated retail building.
• The fuel business: sales volume, margin and the supply arrangement.
• The convenience store or other operations: retail sales, and sometimes a car wash, quick-service food or automotive service.
• The equipment: tanks, piping, dispensers, point-of-sale and canopy.
• Licences, permits and contracts.

Some stations are owned and operated by the same party; others are owned by a fuel company or investor and operated by a dealer or lessee under an agreement. Understand exactly which structure applies, because it determines who bears the risk and who controls pricing, branding and supply.

Regulatory Status: Fuel Handling in Ontario

In Ontario, the Technical Standards and Safety Authority (TSSA) regulates the handling and storage of fuel. Ontario Regulation 217/01 (Liquid Fuels) covers facilities such as retail outlets where gasoline and related products are handled, loaded or dispensed for use as fuel in motor vehicles. Under the regulation, facilities generally must be licensed by TSSA and modifications must be approved, and the safe storage and use of fuel is governed by the TSSA’s Liquid Fuels Handling Code. Underground fuel storage tanks must meet registration and contractor-qualification requirements. As a buyer you should:

• Confirm the station’s TSSA licence, that it is current, and what is needed for it to be transferred or reissued on a change of ownership.
• Obtain the registration and inspection records for the tanks and piping, including age, construction type, leak-detection systems and testing history.
• Understand the remaining life of the tanks and the cost of replacement or removal, which can be substantial.
• Check for any TSSA orders, findings or unresolved deficiencies.

Confirm current requirements directly with the TSSA and a qualified consultant, since they can change.

Environmental Due Diligence

Petroleum hydrocarbon contamination of soil and groundwater is a well-known risk at fuel sites, whether from tank or line leaks, spills at dispensers or historic operations. Environmental due diligence typically proceeds in stages:

1. Phase I environmental site assessment: records review, historical searches, site inspection and interviews to identify potential contamination. In Ontario, these are commonly done to the CSA Z768 standard, or to Ontario Regulation 153/04 where the work supports a Record of Site Condition.
2. Phase II environmental site assessment: sampling of soil, groundwater and sometimes vapour, and tank and line testing, where the Phase I identifies areas of concern. For a gas station, a Phase II is usually expected.
3. Remediation planning: if contamination is found, an estimate of cleanup scope, cost and timeline, and who is responsible under the agreement of purchase and sale.

Contamination affects value, financing and liability, and it can take a long time to resolve. A Record of Site Condition filed in the provincial registry is required before a property’s use changes to a more sensitive one, such as residential, which matters if a buyer plans to redevelop. Environmental risk allocation should be negotiated with your lawyer and environmental consultant before conditions are waived. Our due diligence checklist sets out the broader review.

Understanding the Economics

Gas station earnings come from several sources with different characteristics.

• Fuel: margin per litre multiplied by volume. Margins can be thin and volatile, and they may be set or influenced by the supply agreement.
• Convenience store and other retail: typically higher-margin, and often a key contributor to profit. Look at sales mix, shrink, staffing and lottery, tobacco and other categories, and any regulatory licences they require.
• Ancillary income: car wash, food service, ATM, signage and other rents.
• Real estate return: if the property is leased to an operator, the rent is the income, valued as a net-leased property.

Normalize the earnings by deducting a market management wage and an allowance for equipment and tank replacement, as with any operating business. Our guide on how to calculate NOI explains the discipline for the property income. Then separate the real estate from the business, since each carries different risk. The value of the site as real estate should be tested against what other users would pay if the station were closed, and against the potential environmental liability.

Fuel Supply and Branding Agreements

Many stations operate under a supply and branding agreement with a fuel company. Review carefully: the term, minimum volume requirements, pricing formula, exclusivity, rebranding or equipment obligations, financial incentives that may need repayment on early termination, rights of first refusal or consent requirements on sale, and the fuel company’s rights over the site. An agreement that restricts your ability to change supplier or sell can materially affect value. Have your lawyer review it before you commit.

Site, Zoning and Planning

Confirm that a gas station is a permitted use, review any site plan agreements, and check whether the use is legal non-conforming, which can limit expansion and rebuilding. Traffic counts, visibility, access, competing stations and changes to road networks affect long-term volume. Ask about any planned road or transit works, and about municipal policies on fuel stations and drive-through uses.

Financing

Lenders scrutinize gas stations closely because of environmental risk and the operating nature of the business. Expect requirements such as Phase I and Phase II reports, tank records, and evidence of insurance including environmental coverage. Terms and equity requirements may be more conservative than for other commercial property.

Ontario Acquisition Costs

• Land transfer tax: on non-residential property, Ontario’s rates are 0.5% up to $55,000, 1.0% from $55,000 to $250,000, 1.5% from $250,000 to $400,000 and 2.0% above $400,000, with a municipal tax in the City of Toronto.
• HST: sales of commercial real property are generally taxable, and where the purchaser is a GST/HST registrant it typically self-assesses the tax. A sale of a business as a going concern may allow an election. Structure the agreement with your accountant and lawyer.
• Inventory: fuel and store inventory are typically adjusted at closing.
• Professional and technical costs: legal, Phase I and II assessments, tank testing and appraisal.

Common Mistakes When Buying a Gas Station

• Skipping or rushing the Phase II. Unknown contamination is the largest risk at fuel sites.
• Not checking the tanks. Age, records and remaining life drive cost.
• Ignoring the supply agreement. It can restrict pricing, resale and value.
• Valuing on fuel volume alone. Margin and store earnings matter more.
• Not allocating environmental risk in the contract. Decide who bears cleanup before closing.
• Assuming licences transfer automatically. Confirm the TSSA and municipal position.
• Overlooking exit value. Contamination and use restrictions can limit resale.

Frequently Asked Questions

Who regulates gas stations in Ontario?

The TSSA regulates fuel handling and storage under Ontario Regulation 217/01 (Liquid Fuels) and related codes, and municipalities regulate zoning and planning. Environmental matters are governed by provincial environmental law.

Do I need a Phase II environmental assessment for a gas station?

It is usually expected, and lenders commonly require it, because fuel sites carry a higher risk of petroleum contamination.

What happens to the underground tanks?

They must meet registration, testing and safety requirements while in service. Replacement or removal at end of life is a significant cost, and you should obtain records and cost estimates.

Can I change fuel suppliers after buying?

It depends on the supply and branding agreement. Review its term, exclusivity and termination provisions before buying.

Is a gas station a good investment?

It can be, but earnings are operationally driven and environmental risk is high. Underwrite conservatively and get specialist advice.

How do I value a gas station?

Separate the real estate from the business, normalize earnings, and adjust for tank, environmental and supply agreement factors. Use evidence from comparable transactions.

Conclusion

Gas stations reward buyers who treat regulatory status and environmental condition as the first questions, not the last. Verify the tanks and the TSSA position, complete Phase I and Phase II work, review the supply agreement, and price the real estate and the business separately. Before acquiring a commercial property, investors should understand not only the asking price, but also the property’s income, leases, expenses, physical condition and future potential.
