How Much Does a Fiberglass Pool Cost in Ontario?

One of the most common questions homeowners ask when they start thinking about a pool is "how much is this really going to cost?" It is a fair question, and most pool companies do not answer it directly.

We will. The honest answer is that most fiberglass pool projects in Ontario fall between $75,000 and $130,000 CAD. That is the total project cost, not just the pool shell.

The range is wide because every backyard is different. A smaller pool with a simple concrete patio and basic equipment can come in closer to $75,000. A larger pool with a full backyard makeover can push past $130,000.

This article breaks down every part of that cost so you can see exactly where the money goes.

What does $75,000 to $130,000 actually include?

A complete fiberglass pool project includes far more than just the pool shell sitting in the ground. When a pool company gives you a quote in that range, it should cover all of the core work needed to go from an empty backyard to a finished, swimmable pool.

Here is what a typical fiberglass pool project includes:

• The pool shell itself — the fibreglass unit manufactured by companies like Thursday Pools or Azoria
• Delivery and crane placement — getting the shell to your property and lowering it into the excavation
• Excavation — digging the hole to the exact specifications for your pool model
• Gravel base and backfill — crushed stone underneath and around the pool for proper drainage and support
• Plumbing — the pipes connecting your pool to the pump, filter, and returns
• Electrical — wiring for the pump, lights, and any automation
• Basic equipment — pump, filter, and sanitizer system
• Patio or decking — the surface around your pool (at minimum, a basic concrete apron)
• Fencing — required by the City of London and most Ontario municipalities before the pool can be filled

Not every quote includes everything on this list. That is one of the most important things to check when comparing quotes from different companies.

Complete cost breakdown by category

Here is how the total project cost typically breaks down for a mid-range fiberglass pool project in Ontario:

Category	Typical Range (CAD)	% of Total
Pool shell (delivered)	$25,000 – $45,000	30–35%
Excavation & backfill	$8,000 – $15,000	10–12%
Patio / decking	$12,000 – $35,000	15–25%
Equipment (pump, filter, sanitizer)	$5,000 – $8,000	6–8%
Plumbing & electrical	$5,000 – $10,000	6–8%
Fencing	$3,000 – $8,000	4–6%
Grading & landscaping	$3,000 – $10,000	4–8%
Permits & inspections	$500 – $1,500	1%
Total project	$75,000 – $130,000	100%

The pool shell is the single largest line item, but it is only about a third of the total cost. Everything around the pool, under the pool, and connected to the pool adds up.

What is the biggest cost besides the pool itself?

The patio. In most backyard pool projects, the patio is the second most expensive item after the pool shell itself.

That surprises a lot of homeowners because it looks like "just a bit of concrete." But the patio is measured in square feet, and square feet add up fast.

Most homeowners do not want the bare minimum patio. They want space for chairs. They want space for a table. They want room to walk around the pool without feeling tight. By the time you lay that all out, you are looking at 400 to 800 square feet of patio surface.

Here is how patio costs compare by material:

Patio Material	Cost per sq ft (CAD)	500 sq ft patio
Plain concrete (broom finish)	$18 – $25	$9,000 – $12,500
Stamped concrete	$25 – $35	$12,500 – $17,500
Interlocking pavers	$30 – $45	$15,000 – $22,500
Natural stone	$45 – $70	$22,500 – $35,000

The jump from plain concrete to natural stone can add $15,000 to $20,000 to a project. If you are trying to keep costs down, the patio material is one of the biggest levers you have.

Extra features like steps, seat walls, and fire pit areas also add cost. Each of these can add $2,000 to $8,000 depending on size and material.

How does pool size affect the price?

Pool size is one of the main cost drivers. A bigger pool means more digging, more stone, more backfill, more patio around it, and a bigger equipment package to handle the water volume.

Here is a rough sense of how size affects the pool shell cost alone:

Pool Size	Typical Dimensions	Shell Cost (CAD)
Small	10 x 20 ft or smaller	$22,000 – $30,000
Medium	12 x 24 to 14 x 30 ft	$28,000 – $38,000
Large	16 x 32 ft and up	$35,000 – $48,000

But the shell cost is only part of the picture. A larger pool needs a bigger patio to look proportional, a more powerful pump and filter, more plumbing, and more excavation. The total project difference between a small and large pool is typically $25,000 to $40,000.

For most backyards in London and Southwestern Ontario, a medium-sized pool (12 x 24 to 14 x 30 feet) is the sweet spot. It gives enough room for swimming and lounging without overwhelming the yard.

What does pool equipment cost?

Every pool needs three basic pieces of equipment: a pump, a filter, and a sanitizer system. Together, these make up the core of what keeps your pool water clean and circulating.

A basic equipment package with a variable-speed pump, cartridge filter, and standard chlorine system typically costs $5,000 to $8,000 CAD installed.

Variable-speed pumps cost more upfront than single-speed pumps, but they use significantly less electricity. Most pool companies now include variable-speed pumps as standard because the energy savings pay for the price difference within a couple of years.

What about heaters, salt systems, and covers?

Beyond the basics, there are several popular upgrades that homeowners add to their pool projects. None of these are required, but they affect your daily experience and long-term costs.

Upgrade	Cost (CAD)	What it does
Gas heater	$4,500 – $7,000	Heats water quickly, higher running cost
Heat pump	$5,500 – $9,000	Heats water slowly, much lower running cost
Salt water system	$2,500 – $4,500	Generates chlorine from salt, softer-feeling water
Automatic pool cover	$15,000 – $25,000	Motorized safety cover, retains heat, reduces evaporation
LED pool lights	$800 – $2,500	Colour-changing or white underwater lights
Pool automation	$2,000 – $5,000	Control pump, heater, and lights from your phone
Water feature (bubblers, deck jets)	$1,500 – $5,000	Adds visual and sound elements to the pool

An automatic pool cover is the most expensive upgrade on this list, but it serves double duty as both a safety cover and a heat-retention system. In Ontario's climate, it can extend your swim season by several weeks on each end.

A salt water system does not mean your pool is chlorine-free. The salt cell converts salt into chlorine. The water just feels softer and there is no chlorine smell. It is a popular upgrade, but the salt cell needs to be replaced every 3 to 7 years at a cost of $800 to $1,200.

Why do pool quotes vary so much between companies?

If you get three quotes from three different pool companies, you will almost certainly get three different prices. Sometimes the gap is $20,000 or more. That does not necessarily mean one company is ripping you off and another is giving you a deal.

Here is what usually explains the difference:

• What is included. Some quotes include the patio, fencing, and landscaping. Others only cover the pool, equipment, and excavation. If you are comparing a $75,000 quote against a $95,000 quote, check what each one actually includes before assuming the lower one is better.
• Patio size and material. One company might quote 400 square feet of plain concrete. Another might quote 600 square feet of stamped concrete. That alone can be a $10,000 difference.
• Equipment quality. A quote with a single-speed pump and basic filter will be cheaper than one with a variable-speed pump, salt system, and heater. But the cheaper equipment costs more to run every year.
• Pool shell manufacturer. Different fiberglass pool manufacturers price their shells differently. A premium shell with a thicker gel coat and better warranty can cost $5,000 to $10,000 more than an economy shell.
• Site conditions. Companies that visit your yard before quoting can price in the real conditions. Companies that quote sight-unseen may add change orders later.

The most important question to ask when comparing quotes is: "What is and what is not included in this number?" Get every company to break the quote into line items so you can compare apples to apples.

What does pool maintenance cost per year?

Once the pool is in, it costs money to run. For a fiberglass pool in Ontario, expect roughly $1,000 to $3,000 per year in maintenance costs.

The biggest variable is whether you heat your pool.

Annual Cost	Range (CAD)
Chemicals (chlorine, pH, alkalinity)	$250 – $500
Electricity (variable-speed pump)	$150 – $350
Water top-ups	$75 – $175
Opening and closing (if you hire it out)	$500 – $800
Heating (if you use a heater)	$400 – $1,200
Total without heating	$1,000 – $1,500
Total with heating	$1,500 – $3,000

Fiberglass pools have lower maintenance costs than concrete pools because the smooth gel coat surface resists algae growth. That means fewer chemicals, less scrubbing, and less time spent on upkeep.

One tip: insulating under and around the pool shell helps hold heat in the water. A solar blanket on top can warm the water on its own during hot days, reducing how often you need to run the heater.

Why are pools more expensive in Ontario than in the United States?

If you have been researching pool costs online, most of the pricing you have seen is American. Pool prices in Ontario are genuinely higher, and there are several reasons why.

• Exchange rate. The Canadian dollar is worth less than the US dollar. A pool shell priced at $25,000 USD becomes roughly $34,000 to $35,000 CAD at current exchange rates.
• Import duties. Fiberglass pool shells manufactured in the US are subject to customs duties when they cross the border.
• Shorter building season. Ontario's pool companies have roughly 6 to 7 months of building weather, compared to 10 or 11 months in the southern US. That means higher per-project labour costs because the same overhead is spread across fewer projects.
• HST. Ontario charges 13% Harmonized Sales Tax on pool installations. Many US states charge 6% to 8% sales tax.
• Winterization. Every pool in Ontario needs to be properly closed for winter and opened in spring. This is an added cost that pool owners in Florida or Arizona never deal with.

A pool that costs $60,000 USD in Virginia might cost $85,000 to $95,000 CAD in Ontario for the same pool, same size, and comparable finishes. That is just the reality of building in Canada.

Why do pool prices keep going up every year?

Pool prices have increased every year for the last several years. This is not unique to pools. It is driven by the same forces affecting all construction costs.

Materials cost more. Labour costs more. Equipment costs more. A pool that was quoted around $85,000 a few years ago could easily be $10,000 to $15,000 more today. That is for the same pool in the same backyard.

There is no sign of this trend reversing. If you have been thinking about a pool for a while, the price today is almost certainly lower than it will be next year.

Many families also spend $4,000 to $5,000 per summer on vacations. Over three summers, that is $12,000 to $15,000 that came and went. You come home, unpack, and the backyard looks the same as when you left. A pool stays in your backyard every summer after it goes in.

Fiberglass vs concrete: which costs less?

Fiberglass pools are generally less expensive than concrete pools, both upfront and over time.

	Fiberglass	Concrete
Upfront cost (Ontario)	$75,000 – $130,000	$100,000 – $180,000+
Installation time	2 – 4 weeks	3 – 6 months
Annual maintenance	$1,000 – $3,000	$2,500 – $5,000+
Resurfacing	Not typically needed	Every 10 – 15 years ($15,000 – $30,000)
Lifetime maintenance cost (25 years)	$25,000 – $50,000	$75,000 – $150,000+

Concrete pools offer more flexibility in shape and size because they are built on-site from scratch. If you need a pool deeper than 8 feet, wider than 16 feet, or a completely custom shape, concrete may be your only option.

But for most homeowners who want a standard-sized pool with a proven design, fiberglass costs less upfront and significantly less over the life of the pool. The smooth gel coat surface means less chemical use, less algae, and no resurfacing. That is where the real long-term savings are.

We install fiberglass pools, so we have a bias. But we will be the first to tell you when concrete might be the better choice for your specific situation.

What this means for homeowners in London, Ontario

London and Southwestern Ontario have a few things that make pool projects here a little different from other parts of the province.

The City of London requires a swimming pool fence permit before any pool work can begin. Not after. Before. Your pool company should handle the permit process for you, but make sure you ask.

The building season in this area runs roughly from April through October. Most pool companies book their summer installs months in advance. If you want to be swimming by July, the planning usually needs to start the previous fall or winter.

Lot sizes in London's newer subdivisions tend to be smaller than in older neighbourhoods like Byron, Lambeth, or Old South. A smaller lot does not mean you cannot get a pool. It just means the pool size, patio layout, and setback requirements need more careful planning.

Soil conditions in the London area vary. Some areas have sandy soil that is easy to excavate. Others have heavy clay or high water tables that require extra work. A good pool company will assess your site conditions before giving you a final price.

The communities we serve, including Komoka, Strathroy, Dorchester, and St. Thomas, each have their own municipal requirements for pool permits and fencing. Your installer should know the specific rules for your area.
