![High-efficiency condensing boiler installed in a Toronto mechanical room with copper manifold and pressure gauges](/images/misc/clean-high-efficiency-condensing-hydronic-boiler-f.webp)

Toronto Boiler Installation delivers TSSA-licensed boiler installation, high-efficiency condensing retrofits, combi swaps, hydronic system design, and 24 hour emergency boiler service across Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill, and the wider GTA. Our four transparent CAD scope bands are published on the page: diagnostic from $99 CAD, standard part repair from $200 CAD, major component replacement from $1,200 CAD, and full high-efficiency condensing boiler installation from $6,500 CAD, with the diagnostic fee waived when you authorise the installation on the same visit. Every technician holds a valid TSSA G1 or G2 gas certification, and every quote itemises the parts, labour, permits, and CAD total before payment.

**GTA Cost Benchmark:** A Toronto boiler installation costs $4,500 to $8,500 CAD for a combi boiler, $6,500 to $12,000 CAD for a 95%+ AFUE high-efficiency condensing boiler, and $8,500 to $18,000 CAD for a commercial rooftop installation. Enbridge Home Efficiency Rebate Plus offsets up to $6,500 CAD and Canada Greener Homes Grant offsets up to $5,000 CAD on qualifying installations, with combined rebate potential up to $11,500 CAD.

Most calls come from a trigger: boiler failed on the first cold snap, ignition sequence not firing, system losing pressure daily, heat exchanger showing corrosion, 25-year old cast iron finally cracked, landlord needing certification for RentSafeTO, or commercial operator failing TSSA inspection. Diagnostic, quote, and installation handled end to end.

Common Objections

## What Actually Stops Toronto Homeowners From Replacing an Aging Boiler

Four objections come up on almost every call. Here is the straight answer to each, with the CAD numbers attached.

### 1\. “The quote is huge, I am being oversold”

A high-efficiency condensing swap runs $6,500 to $12,000 CAD because it includes a new condensate line, PVC flue rework, near-boiler piping, expansion tank, zone controls, and the TSSA permit. Every line item appears on the quote in CAD. Combined Enbridge and federal rebates offset up to $11,500 CAD.

### 2\. “You cannot tell if the technician is really licensed”

Ontario requires TSSA G1 or G2 certification for gas boiler work, plus CSA B51 for large-BTU pressure vessels. Certificate numbers appear on every invoice and TSSA permit numbers appear on completed work.

### 3\. “Nobody publishes the price”

Our four CAD scope bands are published on this page: diagnostic $99 to $249, standard repair $200 to $1,200, major repair $1,200 to $3,500, and full combi installation $4,500 to $8,500. High-efficiency condensing runs $6,500 to $12,000 CAD.

### 4\. “The boiler is 25 years old, repair or replace?”

Cast iron lasts 30 to 50 years but drops to 60 to 70 percent efficiency by year 25. A modern 95% AFUE unit cuts natural gas bills 25 to 35 percent, qualifies for up to $11,500 CAD in rebates, and pays back in 6 to 10 years. You get a written repair-versus-replace on every diagnostic.

Why Licensing Matters

## TSSA-Licensed Installation vs. Unlicensed or Handyman Work

Gas boiler work is one of the few trades where the cheapest quote can carry the largest hidden risk. Here is what actually differs.

| What It Affects | TSSA-Licensed Installation | Unlicensed or Handyman Work |
| --- | --- | --- |
| Certification | TSSA G1 or G2 certified, certificate number printed on every invoice | No certification requirement, no verifiable number |
| Manufacturer warranty | Stays valid with Ontario distributor parts and licensed labour | Frequently voided by generic parts or unlicensed installation |
| Code compliance | Ontario B149 fuel code, CSA B51, and Building Code Part 6 and 7 | No code review, no TSSA permit pulled |
| Insurance coverage | $2M commercial general liability insurance, WSIB registered | Often uninsured for gas appliance work |
| Rebate eligibility | ENERGY STAR installer, Enbridge and Canada Greener Homes paperwork filed | Rebates unavailable without a qualifying licensed installer |
| Safety verification | Combustion analysis with a CO monitor on every installation | No combustion verification, higher risk of an undetected leak |

Ask any contractor for their TSSA certificate number before work starts. We print ours on every invoice.

Market Context

## Why So Many Toronto Boilers Are Being Replaced Right Now

Toronto has one of the largest concentrations of hydronic heating in North America, and most of it is aging at the same time. The pre-1950 housing stock across Riverdale, Leslieville, The Annex, Cabbagetown, High Park, and Bloor West Village was built around cast iron column radiators fed by gravity hot water systems. Those radiators are still excellent. The boilers feeding them have been replaced once, typically in the 1990s, which puts a very large share of GTA equipment in the 25 to 35 year window right now.

That matters because a cast iron sectional lasts 30 to 50 years mechanically but drops to 60 to 70 percent efficiency by year 25. The unit keeps running. The gas bill keeps climbing. A modern 95%+ AFUE condensing boiler cuts that consumption 25 to 35 percent, and with Enbridge Home Efficiency Rebate Plus at up to $6,500 CAD and the Canada Greener Homes Grant at up to $5,000 CAD, the payback on a $6,500 to $12,000 CAD installation typically lands between 6 and 10 years.

The newer half of the GTA is on a different clock. Vaughan, Brampton, Markham, and Richmond Hill subdivisions built from the 1990s onward run wall-mounted combi and condensing units with a 12 to 18 year service life. Those are reaching end of life in waves, street by street, because whole neighbourhoods were finished within a two or three year window with identical equipment. A combi swap there runs $5,500 to $9,500 CAD.

Both patterns lead to the same practical question: repair or replace. Every diagnostic we run ends with that comparison in writing, showing repair cost against remaining service life, projected gas savings, and the rebate offset. Roughly one call in five ends with us quoting the repair.

Got Questions?

## Frequently Asked Questions

### How much does boiler installation cost in Toronto?

Combi boiler installation runs $4,500-$8,500 CAD, high-efficiency condensing (95%+ AFUE) $6,500-$12,000 CAD, and commercial rooftop $8,500-$18,000 CAD. Enbridge Home Efficiency Rebate Plus offsets up to $6,500 CAD and Canada Greener Homes Grant offsets up to $5,000 CAD on qualifying installations.

### What is the diagnostic fee?

$99-$249 CAD business hours, $199-$349 CAD after hours. It is waived when you authorise installation or major repair on the same visit.

### Do I need a TSSA-licensed technician in Ontario?

Yes. Ontario B149 fuel code and CSA B51 pressure vessel code both require TSSA G1 or G2 certification. Certificate numbers appear on every invoice.

### How old should a boiler be before I replace it?

Cast iron sectional lasts 30-50 years but drops to 60-70% efficiency by year 25. Wall-mounted condensing lasts 15-20 years. Replace at 25+ where the efficiency gap plus Enbridge and federal rebates pay back in 6-10 years.

### What Ontario rebates apply to a high-efficiency boiler?

Enbridge Home Efficiency Rebate Plus up to $6,500 CAD (qualifying 95%+ AFUE with insulation). Canada Greener Homes Grant up to $5,000 CAD. Canada Greener Homes Loan up to $40,000 CAD at 0% interest. We file the paperwork.

### 80% AFUE vs 95%+ AFUE condensing?

80% mid-efficiency: $3,500-$5,500 CAD installed, no rebate. 95%+ condensing: $6,500-$12,000 CAD installed, cuts natural gas bills 25-35%, qualifies for up to $11,500 CAD combined rebates.

### Can you install a boiler on an older Toronto home with cast iron radiators?

Yes. High-efficiency condensing boilers work with cast iron radiator distribution paired with mixing valves and return-water temperature protection. Retrofit $8,500-$14,500 CAD depending on radiator count and near-boiler piping complexity.

### Do you install commercial rooftop boilers in Toronto?

Yes. TSSA-licensed for BTU inputs above 400,000, CSA B51 certified for pressure vessel installations, and Ontario Boiler and Pressure Vessel Safety Act compliant. Commercial rooftop $8,500-$18,000 CAD depending on BTU capacity.

### How long does a boiler installation take from quote to commissioning?

A standard residential swap is installed within 3 to 7 business days of quote approval and takes one working day on site. Emergency no-heat replacements are scheduled within 24 to 48 hours. Cast iron conversions with new near-boiler piping and chimney liner de-commissioning usually take one and a half to two days.

### Do you pull the TSSA permit and handle inspections?

Yes. Every gas boiler installation is permitted and completed to Ontario Building Code Part 6 and Part 7, B149 fuel code, and CSA B51 where the pressure vessel rules apply. We book the inspection, meet the inspector, and hand over the closed permit with the written workmanship warranty.

### Can I finance a boiler replacement in Ontario?

Yes. The Canada Greener Homes Loan provides up to $40,000 CAD at 0% interest over 10 years on qualifying retrofits, and it stacks with the Enbridge Home Efficiency Rebate Plus and the Canada Greener Homes Grant. We confirm eligibility during the site assessment and file the paperwork on your behalf.

### Which parts of the GTA do you cover?

Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill, North York, Scarborough, Etobicoke, and Oakville, with same-day dispatch and 4-hour cold-snap response across all ten cities.

### What warranty comes with the work?

You receive a written workmanship warranty on labour and the manufacturer warranty on parts. Registering the unit with the manufacturer and using Ontario distributor parts keeps that parts warranty valid, which is why we file the registration for you at commissioning.

### Can you certify a boiler for RentSafeTO or Fire Code compliance?

Yes. Landlords regularly call us for certification ahead of RentSafeTO evaluations and Ontario Fire Code section 6 obligations. We inspect combustion, venting, pressure relief, and gas train, document the result, and issue a report naming the TSSA certificate number of the technician who performed the work.

### Will you tell me honestly whether to repair or replace?

Every diagnostic ends with a written repair-versus-replace analysis. It compares the repair cost against the remaining service life, the current AFUE, the projected natural gas savings of a 95%+ condensing unit, and the rebate offset. If the repair is the better value we say so and quote the repair.
