How much does it cost to open a pool in Toronto?

Between $250 and $630 depending who you ask and where you are. PF Pools charges $630 plus HST in Mississauga and the GTA for a two-visit opening that includes a start-up and a 20 minute vacuum on the second visit. Swim Clean Pool Service starts at $500 plus HST across Toronto and York Region, including up to two visits and 20 litres of chlorine. John C Young Design, writing for Ontario generally, puts a hired opening at $250 to $400. A GTA quote will sit near the top of that band.

What does a pool closing cost?

$250 to $530. PF Pools charges $530 plus HST for a one-visit closing in the GTA and John C Young Design puts an Ontario closing at $250 to $450. Booked as a pair, Ontario Pool Services publishes an opening and closing package at $425 for an above-ground pool, $550 for an inground opening plus closing and $650 with deck service, and Toronto Pool cites a Toronto market range of $250 to $500 for the pair.

Why is my quote higher than the advertised price?

Because both published GTA price lists charge per feature, and they charge at each end of the season. PF Pools adds $100 plus HST each for an attached spa, a negative edge, a double cover or a pool over 800 square feet, and $50 for a waterfall. Swim Clean adds $125 for an attached spa opening and $25 for each additional feature such as deck jets, an automatic cleaner or an auto-fill. A pool with a spa and two features carries those twice a year.

What if the pool comes up green?

It costs more, and both companies say so in advance. PF Pools charges $100 plus HST for each additional visit to an opening or closing, and Swim Clean notes that pools with heavy debris or green water may need extra vacuuming billed hourly. A green opening is usually a closing that went wrong six months earlier, which is the argument for spending properly at the other end of the season.

Is it worth opening and closing a pool yourself?

On money alone, clearly. John C Young Design prices a DIY opening or closing at $50 to $100 each in chemicals against $250 to $450 hired, so a season is $100 to $200 instead of $500 to $800. The risk sits entirely on the closing: Project Landscaping puts the damage from improper winterisation at $2,000 to $10,000 and up, which is several years of hired closings in one burst pipe. Plenty of GTA owners split the difference and open the pool themselves while paying somebody to close it.

When should a Toronto pool be opened?

April into May, once temperatures stay above freezing, and earlier than most people think. Swim Clean Pool Service makes the point that opening at the right time prevents algae growth and reduces cleanup costs, which is the same thing as saying a late opening is a dearer opening. Water that warms under a closed cover is water that turns, and the extra visits that follow are billed.

What does opening and closing a pool cost here?

Last updated:August 26, 2026By The Pool Trade Desk

$500 to $630 plus HST to open in the GTA and $530 to close, plus a surcharge for every feature, charged at both ends of the season. Two local companies publish their actual price lists, which is what this is built on.

Every surcharge is charged at both ends of the season, because that is how the published price lists word them: a pool with a spa and two water features pays the add-ons in April and again in October. The GTA figures sit well above the wider-Ontario ones and both are in the band, so a Toronto quote should be read against the top of it.

Why two identical pools get different bills

Method

This is the one pool cost in the GTA where companies publish real prices rather than ranges, so the tool is unusually firm. PF Pools lists every line for Mississauga and the GTA, all of it plus HST. Swim Clean Pool Service publishes a starting price for Toronto and York Region and lists exactly what is inside it: up to two visits, 20 litres of chlorine, cover off and stored, equipment reconnected, one hour of cleaning, water tested and balanced, and a metre of deck swept.

The surcharges are where two identical-looking pools separate. Both companies charge per feature and both charge at each end of the season, so an attached spa is $100 to $125 in April and again in October, and a waterfall is $25 to $50 each time. A pool over 800 square feet, a negative edge and a double cover are each a further $100 per visit on PF Pools' list. Add a spa, a waterfall and a big surface and the season carries several hundred dollars of add-ons before anything goes wrong.

Something usually does go wrong at the opening, and it is nearly always the previous closing coming back. A pool that comes up green costs another $100 plus HST per visit at PF Pools, and Swim Clean bills heavy debris hourly. The honest way to read that: the closing is the expensive service and the opening is where you find out whether it was done properly.

Wider Ontario is genuinely cheaper than the GTA here and the bands cover both, which is why they look wide. John C Young Design prices an Ontario opening at $250 to $400 and a closing at $250 to $450, roughly half the published GTA figures. If you are in Toronto, read a quote against the top of the range rather than the middle.

Where these figures come from

Provenance

Two GTA companies that publish an itemised price list, which is rare in this trade, plus four Ontario sources for the wider market and for what a bad winterisation costs.
