A gas station buyer checklist covers the registration and testing history of underground and aboveground fuel storage tanks, environmental liability that can run with the land, the fuel supply agreement’s exclusivity and assignment terms, and the separate retail licences a convenience-store operation typically bundles.

This checklist covers what to verify before buying a Canadian gas station or fuel retail site. A fuel retail business carries environmental and regulatory exposure tied directly to its storage tanks and its history on the land, exposure that can survive a change of ownership and even a change of use, which makes the tanks, the site’s environmental history and the fuel supply agreement the three places diligence needs to start.
Confirm the fuel storage tanks are compliant and properly documented
Request the registration, installation records and most recent inspection and testing documentation for every underground and aboveground fuel storage tank on the siteIn Ontario, the Technical Standards and Safety Authority regulates fuel storage tank compliance under the Liquid Fuels Handling Code, and other provinces run comparable technical-safety regimes; a tank without current, documented testing is a red flag worth resolving before closing, not after.
Ask directly whether any tank has ever failed a test, been upgraded, decommissioned or replaced, and request the documentation for any such workAn undocumented tank replacement or a past failed test that was never properly closed out on the regulator’s file can surface as a compliance problem the new owner did not know it inherited.
Confirm who holds the operating licence or registration for the fuel facility and what the process is for transferring or reissuing it to the new ownerA facility’s authorization to store and dispense fuel is generally tied to the operator, and a change of ownership can require its own application rather than a simple transfer.
Check environmental liability tied to the site
Commission a Phase I environmental site assessment, and a Phase II if the Phase I identifies a concern, before finalizing the dealFuel-retail sites carry environmental liability that can run with the land itself, particularly under a share purchase, and a buyer who skips this step can end up responsible for contamination it never caused.
Ask for the site’s full environmental history, including any past spills, remediation orders or groundwater monitoring results, even for periods well before the current ownerContamination from decades-old tanks or a prior operator can still be the current owner’s — and potentially the new owner’s — responsibility, so site history matters well beyond the seller’s own tenure.
Confirm whether the property carries environmental liability insurance and, if so, whether that coverage can extend to or be replaced by the new ownerEnvironmental coverage is not automatic, and a gap between the seller’s policy ending and the buyer’s own coverage starting can leave contamination risk uninsured during the transition.
Review the fuel supply agreement and convenience-store operations
Request the current fuel supply or branding agreement and confirm its term, exclusivity, pricing formula and any anti-assignment clauseA fuel supply agreement tied to a specific brand can restrict where the station buys fuel and at what margin, and an anti-assignment clause can mean the agreement does not simply follow the sale without the supplier’s separate consent.
Confirm whether the station operates under a dealer, lessee-dealer or company-operated arrangement with the fuel supplier, since each carries different rights and obligations for the operatorHow the fuel relationship is structured affects who actually controls pricing, branding and the ability to sell the site, and it is worth confirming which model applies rather than assuming.
If the site sells tobacco, lottery products or propane, confirm each of those separate retail licences is current and understand what re-registration a change of ownership triggersA gas station bundles several separate retail licences beyond the fuel authorization itself, and a lapse in any one of them on day one can cut off a meaningful part of the site’s convenience-store revenue.
