What Actually Stops GTA 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.

Dispatch Across Agincourt, Guildwood and Birch Cliff
Scarborough dispatch runs on Highway 401 with Kingston Road, Lawrence Avenue East, Sheppard Avenue East, and Markham Road as the local connectors. Agincourt sits north of the 401 around Sheppard and Kennedy, Guildwood south along Kingston Road, and Birch Cliff on the bluffs west of Midland. Same-day dispatch covers the Scarborough M-series postal codes.
Distance is the variable here. Scarborough is large, so we schedule by corridor rather than by appointment slot, grouping calls along Kingston Road or Sheppard Avenue East on the same run. That keeps arrival windows tight instead of giving you a full-day window.
Cold-snap response is four hours. On a no-heat call in post-war housing stock the diagnosis usually resolves quickly, because the failure modes on 25 to 40 year old gas boilers are well known and the parts for the common repairs are on the truck.
Post-War Scarborough Homes and End-of-Life Gas Boilers
Agincourt, Guildwood, and Birch Cliff were built out through the 1950s and 1960s as post-war family housing. Basements are full height, utility rooms are small, and the heating system has usually been replaced once already. The equipment installed in that second round is now at the end of its service life.
The common pattern is a mid-efficiency gas boiler running around 80 percent AFUE, venting into a masonry chimney, feeding either original radiators or hydronic baseboard added during a renovation. It still works, but it is burning roughly a third more gas than a modern condensing unit would for the same heat, and it has no rebate value.
A lot of Scarborough homeowners choose a combi at replacement because it removes the separate hot water tank and frees floor space in a small utility room. Where the house still runs radiators, the better answer is usually a condensing boiler with return-water temperature protection so the radiators stay and the efficiency gain is real rather than theoretical.
- End-of-life mid-efficiency gas boiler replacement
- Combi swaps that remove the separate hot water tank and free utility room space
- Condensing retrofits that retain original radiator distribution
- Masonry chimney de-commissioning and PVC side-wall venting
- Red-tag clearance and TSSA violation resolution
