Outdated wiring (knob-and-tube, aluminum, or 60A panel) increases fire risk and voids insurance. Many Canadian insurers will not provide or renew coverage without a full rewire – especially if you later add smart devices that draw more standby power.
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.
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
Two Major Cost Factors
Accessibility – Walls intact? More labour for fishing wires + drywall repair (2,000–10,000 extra)
Electrical Panel Upgrade – 100A to 200A costs 1,500–8,000 (mandatory for smart homes)
electrical panel upgrade cost Canada
Cost per Square Foot (Standard Rewire)
| 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 |
💡 Note: These costs are in addition to a standard house rewire. If you are already rewiring an old house, adding smart wiring adds only 20-30% to the labour, because walls are open.
Labour, Timing & Hidden 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 Upgrade – Mandatory for Smart Homes
A non-negotiable cost. Homes built before 1980 often have 60A or 100A. For a smart home with EV, heat pump, and multiple devices, you need 200A.
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 |

Always plan a budget range – add 20% contingency for hidden issues (e.g., asbestos, outdated junction boxes).
Get at least 3 quotes from licensed electricians who have done smart home pre-wiring.
Don’t compromise on cable quality – use certified Cat6 or Cat6a, and copper (not CCA).
If budget is tight: do standard rewire now but add empty conduits to walls for future smart wiring.
For maximum ROI – a rewired home with smart infrastructure sells faster and at higher value.
