Knob & Tube Rewiring Cost in Toronto (2026 CAD Pricing)

# Knob & Tube Rewiring Cost in Toronto (2026 CAD Pricing)

Toronto K&T rewiring costs in 2026 sit between $8,000 for a small partially-renovated semi and $45,000+ for a large pre-1930 detached home requiring panel upgrade, asbestos abatement, and full plaster patching. The range is wide because every pre-war home is different, and the most expensive parts of the project — asbestos, vermiculite, plaster repair, panel upgrades — are conditional on what the electrician finds when they open the walls.

This post breaks down realistic CAD pricing for the GTA in 2026 across project tiers, line items, and the variables that move pricing up or down. For the full project guide, see [Knob & Tube Rewiring Toronto: Complete 2026 Guide](/blog/knob-tube-rewiring-toronto-2026-complete-guide).

The Three Cost Tiers

Tier 1: Small Home, No Panel Upgrade — $8,000–$15,000

House size: 1,200–1,500 sq ft, 1.5 or 2 storey semi or small detached.
Existing service: 100A modern panel (Eaton, Schneider, Siemens) — reusable.
Wiring: K&T in second floor and attic only, modern wiring in basement and main level (typical of post-1980 partial renovation).
No asbestos or vermiculite issues identified.
Drywall walls (not plaster) on second floor.

Cost breakdown:

Permit + Master Electrician oversight + LEC labour: $5,500–$9,500
Material (Romex 12-2 NMD90, 14-2 NMD90, devices, breakers): $1,000–$1,800
Drywall patching (RenoHouse): $1,200–$2,500
Final paint touch-up: $300–$1,000

Tier 2: Mid-Size Home with Panel Upgrade — $12,000–$25,000

House size: 1,500–2,500 sq ft, 2 or 2.5 storey detached.
Existing service: 60A or 100A old panel (Federal Pioneer Stab-Lok, Wadsworth, or 60A fused) — replace.
Wiring: K&T throughout 60–80% of home.
Possible asbestos paper on basement ducts (Type 1 abatement, $1,500–$3,500 added).
Mix of plaster (older sections) and drywall (renovated sections).

Cost breakdown:

Permit + Master Electrician + LEC labour: $9,000–$16,000
100A or 200A panel upgrade with Eaton, Schneider, or Siemens: $2,500–$4,500
Toronto Hydro service disconnect/reconnect: $300–$800
Material: $1,800–$3,200
Asbestos Type 1 abatement (specialist): $1,500–$3,500 (if required)
Drywall and plaster patching: $2,500–$5,000
Paint: $800–$2,000

Tier 3: Large Pre-1930 Detached, Full Coordination — $20,000–$45,000+

House size: 2,500–4,000+ sq ft, large pre-war detached (Annex, Forest Hill, High Park, Wychwood).
Existing service: 60A or 100A — replace with 200A.
Wiring: K&T plus knob-and-tube tap-spliced to BX cable from past partial renos. Full audit needed.
Vermiculite attic insulation requiring Type 2 abatement before fishing.
Plaster walls throughout. Hardwood floors over plaster ceilings.

Cost breakdown:

Permit + Master Electrician + LEC labour: $15,000–$28,000
200A panel upgrade plus service mast and meter base: $3,500–$6,000
Material: $3,000–$5,500
Vermiculite Type 2 abatement: $3,000–$8,000
Asbestos paper abatement: $1,500–$4,000
Plaster patching (skim coat over patch repairs): $4,000–$10,000
Paint: $2,000–$5,000

Per-Circuit and Per-Outlet Pricing

Some Toronto LECs quote on a per-circuit or per-outlet basis. 2026 rough numbers:

Per outlet replacement (rewire feed plus device): $180–$320
Per light fixture (rewire plus reinstall existing fixture): $220–$380
Per dedicated circuit (kitchen counter, laundry, EV charger): $450–$900
Per home run from panel to first device: $250–$500

Per-unit pricing is useful for partial scope work and additions but is rarely cheaper than fixed-price full-house rewire pricing for K&T removal scope.

What Drives Pricing Up

Plaster walls vs. drywall: 15–25% labour premium for plaster.
Federal Pioneer panel (must replace): $2,500–$4,500 added.
60A service (must upgrade to 100A or 200A): $3,000–$6,000 added.
Asbestos paper duct wrap: $1,500–$3,500 abatement added.
Vermiculite attic insulation: $3,000–$8,000 abatement added.
Finished basement ceiling (popcorn or drywall): adds drywall and asbestos exposure if pre-1990 popcorn.
Multiple kitchens / in-law suite: extra circuits, EV-style sub-panels, more devices.
Smart home integration: low-voltage cabling, smart switches, dimmers — typically adds $1,500–$5,000.

What Drives Pricing Down

Open access (unfinished basement, accessible attic) makes fishing fast.
Drywall instead of plaster halves the patching time.
Recent panel upgrade (last 10 years) means panel can be reused.
No asbestos/vermiculite: confirmed by sampling.
Single storey (bungalow) versus 2.5 storey: easier fishing routes.

Drywall and Paint: The Hidden Line Items

Many quotes from electrical-only contractors exclude drywall patching and paint. Toronto homeowners are routinely surprised by the post-rewire patching scope. A typical 2,000 sq ft rewire opens 30 to 60 small wall and ceiling sections, plus the 2 to 4 large openings around the panel and major junctions. Patching costs run $2,500–$8,000 depending on plaster vs. drywall, and paint adds $1,500–$4,500.

RenoHouse projects include drywall patching and basic paint touch-up in scope by default. We do this because we have learned that homeowners who get an "electrical only" quote and a separate drywall quote later end up paying 25–40% more than a coordinated quote, and the project drags an extra 2–4 weeks while a separate drywall trade is sourced.

Financing the Project

Toronto homeowners commonly finance K&T rewiring through:

HELOC (Home Equity Line of Credit) — most common, prime + 0.5% to prime + 2%.
Mortgage refinance — at renewal or with prepayment penalty if mid-term.
Renovation loan — credit unions and some big-five offer dedicated reno products.
Insurer payment plan — rare; some insurers offer 12-month bridge premium with rewire deadline.

The CMHC's eco-improvement programs and federal Greener Homes Loan do not cover K&T rewiring directly, but if you bundle the rewire with an envelope upgrade (insulation, windows) the bundled project may qualify for partial financing.
