Gas heater, heat pump or control fault. Diagnosis first — most heater calls are not a dead heater.

CAD, before HST · Caledon. Diagnosis can change this.
Detection, parts and labour are separate line items. Ask for all three in writing.
Repair quotes are hard to compare because four or five numbers get folded into one sentence: diagnosis, labour, parts, access and HST. Split them out and two Caledon quotes for the same fault stop looking $800 apart.
Caledon routes are rural: acreage lots, long driveways and well water instead of municipal supply. Crews price the drive, not the pool, and water hauling is often unavoidable on a liner replacement — confirm the tanker cost before you compare totals.
Access is the line most likely to move in Peel Region. A heater in a shed with a clear path is a straight repair; a pump under a low deck in Bolton may need deck work before anyone touches the motor. Mention the layout when you book so the diagnostic call is priced for the real job.

Widest planning band for each symptom, CAD before HST. Parts included unless the itemised note says otherwise. Not quotes.
Detection runs $350–$650 and tells you where the water is going. The repair that follows runs $900–$2,000, because decking usually has to be cut and patched. Do the bucket test first: a pool losing more than 25 mm a day while a bucket of pool water beside it holds steady is a detection call.

Before you book
Repair calls go faster when the technician knows the equipment before the visit. None of this needs a manual — a photo of the data plate is enough.
Confirm coverage by postal prefix when you call — L7 are the prefixes listed for Caledon.
Symptoms and timing
When it started, whether it is constant, and the last change you made to chemicals or equipment.
Equipment model
Photograph the heater, pump or filter data plate — brand, model and serial number.
Water test numbers
Free chlorine, pH, total alkalinity, stabiliser and salt if applicable. Most shops will test for free.
Access notes
Gate width, deck above the equipment, stairs, and whether the pad is in a shed or exposed to weather.
Prior work
Any recent repair, liner replacement or pump swap. Repeat faults are usually a symptom of the first fix.
Local crews
No equipment specialist lists Caledon directly yet, so these Peel Region crews are the nearest listed option. Confirm travel and coverage when you call. Sample listings for design review — verify insurance and WSIB before booking.

Repair FAQ
Every figure on this page is a planning band, not a quote. Diagnosis can change the number, and it should.
Small fixes run $150–$400 and equipment replacement reaches $5,500, with most Caledon calls landing in between. A diagnostic visit is $95–$185, technician labour is roughly $100–$200 an hour, and parts are extra. Leak detection and the repair that follows it are two separate bills.
No company is listed in Caledon yet, so there is no local response time to quote. Regional Peel Region crews cover the area and schedule repair calls same-week in the swim season; if water is actively leaking, say so on the phone — that changes the route.
Often, if you approve the work on the same visit. Ask when you book, and get the answer in writing. This is the simplest line item to confirm before a technician is at your door.
Repair while the unit is under eight seasons old and the fault is a sensor, switch, capacitor or seal. Replace when the heat exchanger or motor housing is cracked, or when the repair quote passes half the price of new equipment. A repaired heater past 12 seasons usually fails again within two seasons.
Not on its own. Equipment swaps and plumbing repairs under existing decking do not normally need one. Work that changes the pool footprint, the deck or the fence line can trigger a permit, and the enclosure still has to meet your municipality's rules afterwards.
