A gas station is really three projects on one site: an underground fuel system regulated by the province, a canopy and forecourt, and a convenience store that is a small retail building with food-service rules. We build gas station and convenience store projects in Calgary and the surrounding communities, coordinating the certified fuel system installer, the civil work and the building, so the site opens as one project instead of three.
Before you buy the land: the Phase I ESA
Do the environmental work first. A Phase I Environmental Site Assessment should be done before you buy land for a gas station, and it is worth doing before you buy an existing station too. The Phase I reviews the site's history, nearby uses and records to find out whether there is a risk of contamination in the soil or groundwater.
A site with a history of fuel storage, or a neighbour that had one, can carry a cleanup obligation that changes the value of the deal. If the Phase I finds concerns, a Phase II with soil and groundwater testing follows. This is a decision for the buyer and their lender, but we want to know the results before we plan any excavation.
Who can install the fuel system
In Alberta, underground and aboveground fuel storage tanks and their piping have to be installed by contractors approved by the Provincial Fire Administrator. Installers now need CPCA or TSSA certification. Recognition through PTMAA, which some installers previously relied on, ended on December 31, 2025, so check that your fuel system installer's certification is current.
Systems storing 2,500 litres or more need an annual operating permit. That is an ongoing obligation for the operator, so build it into the operating plan.
Whoever the general contractor is, the fuel system work itself belongs to the certified installer: tank excavation and installation, piping, dispensers, leak detection and the tie-in to the canopy and the store. Confirm their certification before work starts.
The canopy and forecourt
The canopy is a structure, so it needs engineering and a building permit. It also carries the forecourt lighting, the fire suppression for the dispensers where required, and often the brand's fascia. Points we plan for:
- Snow and wind loads for Calgary, and drainage so meltwater does not freeze on the forecourt.
- Lighting that is bright enough for safety without spilling light onto neighbouring properties.
- Traffic flow, so cars can reach the pumps without blocking the store's parking or the entrances.
- Forecourt drainage with the right separators so fuel does not reach the storm sewer.
The convenience store
The store is a small retail building, but it often has more mechanical work than its size suggests. Coolers and freezers need refrigeration and power. A food counter, coffee station or hot food line brings in Alberta Health Services, including a plan review before construction if food is prepared. Washrooms for customers are expected, and the building needs to be accessible.
If the store includes food service with cooking, it may need a kitchen hood, a grease interceptor and the AHS review, just as a restaurant would. Our restaurant construction page covers the hood, the interceptor and the AHS review in detail.
Permits and approvals
A ground-up gas station involves more approvals than most commercial projects:
- Land use: the site's land use district has to allow a gas station.
- Development permit for the site layout, buildings, canopy, signs and access.
- Building permits for the store and the canopy.
- Fuel system approvals and permits for the tanks and piping, installed by an approved contractor.
- Trade permits for electrical, plumbing, gas and HVAC.
- AHS approval if the store prepares or sells certain foods.
In the towns around Calgary, such as Strathmore, Okotoks or Cochrane, the municipal process differs from Calgary's, so the permit sequence is planned site by site.
Working on an operating site and in Calgary weather
Many gas station projects happen on a site that is still open: a canopy replacement, a new set of dispensers, a store renovation or additional tanks. That means phasing the work so part of the forecourt keeps selling fuel while the rest is fenced off, keeping customers away from excavations, and coordinating with the fuel supplier on deliveries. Safety around live fuel systems comes first, so work near the tanks and dispensers is scheduled with the certified installer and the operator together.
Weather shapes the schedule too. Excavation, tank installation and forecourt concrete are easiest from spring to fall. Concrete poured in a Calgary winter needs heating and protection while it cures, which adds cost, so we try to sequence the underground and paving work for warmer months and leave the store interior for winter. A chinook can open a short window in January, but it is not something to build a schedule around.
On a ground-up site, the store and the canopy can be built while the fuel system is installed, so the order matters. The tanks and the underground piping go in first, followed by the forecourt slab, then the canopy and the dispensers, with the store progressing alongside.
Ground-up fuel sites run $1.5 to $4 million
That is the published 2026 planning range, all-in, for a gas station with a convenience store. It is wide because the sites are so different. The main drivers:
| Item | Why it varies |
|---|---|
| Fuel system | Number and size of tanks, number of dispensers, and diesel or high-flow lanes |
| Site work | Excavation, paving, drainage and any contamination found |
| Canopy | Size, number of islands and brand fascia |
| Store | Size, refrigeration and whether there is food service |
| Extras | Car wash, EV charging or a quick-service restaurant on site |
A renovation of an existing station, such as a new canopy or a store refresh, costs far less, but it starts with the same question about the condition of the existing fuel system.
Fuel site questions
How much does it cost to build a gas station in Calgary?
As of 2026, a full ground-up gas station with a convenience store plans at about $1.5 million to $4 million all-in, varying by scope. The fuel system, the site work and whether the store includes food service make the biggest difference.
Who is allowed to install fuel tanks in Alberta?
Fuel storage tank systems must be installed by contractors approved by the Provincial Fire Administrator, now with CPCA or TSSA certification. PTMAA recognition ended on December 31, 2025, so confirm your installer's certification is current.
Do I need an environmental assessment before buying a gas station site?
Yes, a Phase I Environmental Site Assessment should be done before you buy. It identifies whether past uses could have contaminated the site, which affects cleanup costs, financing and what can be built.
Does my fuel system need an operating permit?
Yes, if it holds 2,500 litres or more. The permit is renewed every year and sits with the operator, not the builder.
Can you renovate an existing gas station or convenience store?
Yes. We take on canopy replacements, store renovations and refreshes. The first step is to check the condition and compliance of the existing fuel system, since it affects what else can be done on the site.
