This guide explains the typical factors that affect house rewiring costs and also covers how smart-home wiring and pre-wiring can change the project scope and budget.
Cost to Rewire a House in Canada: 2026 Cost Guide
Are you planning a smart home wiring renovation or a complete house rewire? This guide covers both: from basic electrical safety upgrades to the specific costs of installing infrastructure for home automation, smart lighting, security sensors, and entertainment systems. Whether you’re in Ontario, BC, or Alberta, get accurate 2026 pricing.
The following ranges are general planning figures. Actual rewiring costs vary based on the home’s size, accessibility, existing wiring, electrical panel, labour requirements, permits, and local conditions.

Standard House Rewiring Cost in Canada (for comparison)
| House Size (sq ft) | Cost per sq ft (low) | Cost per sq ft (high) |
|---|---|---|
| 1,000 sq ft | $10 | $25 |
| 1,500 sq ft | $9 | $25 |
| 2,000sq ft | $8 | $20 |
The complete rewiring of a house in Canada is a generational project crucial for safety, meeting modern electrical load requirements, and maintaining insurance standards.
Overall Cost Range
Full rewire for standard home (up to 1,200 sq ft): 10,000–30,000 CAD
Complex projects (knob-and-tube, plaster walls, large homes): can exceed $50,000
What Affects the Cost to Rewire a House?
- House Size – Larger homes generally require more wiring, labour, and installation time.
- Accessibility – Walls, ceilings, finished areas, and difficult-to-access spaces can increase labour and repair requirements.
- Existing Wiring – The type, condition, and complexity of existing wiring can affect removal and replacement work.
- Labour – Labour costs vary based on project complexity, accessibility, and the amount of electrical work required.
- Electrical Panel – A panel upgrade may be needed when the existing panel cannot support the electrical requirements of the project.
- Permits and Inspections – Applicable permit and inspection requirements can add to the overall project cost.
- Drywall and Plaster Repair – Opening walls or ceilings may create additional repair costs.
- Smart-Home Requirements – Smart switches, structured wiring, network cabling, dedicated circuits, and other smart-home provisions can increase project scope and cost.

Labour, Permits, Timing and Hidden Rewiring Costs
Best time to do smart wiring – during a major renovation when walls are open. This eliminates the biggest cost: opening and repairing walls.
| Item | Cost / Detail |
|---|---|
| Electrician hourly rate | $65 – $130 CAD |
| Duration (full rewire) | 3 – 10 days |
| Drywall/plaster repair (separate contractor) | $2,200 – $10,500 |
| Permit fees | $88 – $1,500 (varies by province) |
Electrical Panel Upgrades for Rewiring and Smart Homes
A non-negotiable cost. Homes built before 1980 often have 60A or 100A.For a smart home with an EV charger, heat pump, and multiple electrical loads, a 200A service may be required depending on the home’s electrical load calculation.
Ontario (ESA): 1,500–4,500 for 100A→200A upgrade
British Columbia (TSBC): 2,500–8,000 (higher permit fees)
Alberta: 2,000–6,000 depending on municipality
Regional Regulations & Permit Fees (Canada)
| PROVINCE | Authority | Minimum Permit Fee | 200A Upgrade Cost |
|---|---|---|---|
| Ontario (ON) | ESA | $88 | 1,500–1,500–4,500 |
| British Columbia (BC) | Technical Safety BC | $131 (circuit alteration) | 2,500–2,500–8,000 |
| Alberta (AB) | Municipal | Varies (100–100–500) | 2,000–2,000–6,000 |

| SCOPE | Low Estimate | High Estimate |
|---|---|---|
| Standard full rewire + 200A panel | $12,000 | $18,000 |
| Standard + smart pre-wiring (Cat6, sensors, neutral) | $18,000 | $26,000 |

Smart Home Wiring Cost in Canada
If you are already rewiring a house, the project can also be an opportunity to plan for future smart-home technology. Smart pre-wiring may include structured cabling, network wiring, dedicated circuits, low-voltage wiring, and provisions for devices that may be installed later.
💡 Note: These costs are in addition to a standard house rewire. If you are already rewiring an old house, adding smart wiring may require less additional labour because walls are already open.
