The questions below address what Renfrew County homeowners most frequently ask about residential electrical work — from verifying whether an electrician is properly licensed, to understanding permit requirements, to older-home issues like knob-and-tube wiring and 60-amp panels that affect much of the county's housing stock.
Do all electricians need to be licensed in Ontario?
Yes. Electrical work is a compulsory trade in Ontario — all electrical work performed for hire must be done by individuals holding a valid ESA Certificate of Qualification. Two C of Q classifications apply to residential work:
- 309A — Construction and Maintenance Electrician: Broadest qualification; covers residential, commercial, and industrial work
- 309C — Residential Electrician: Residential-only qualification; appropriate for most home projects
Additionally, the business must hold a separate ESA Electrical Contractor Licence. Both the individual C of Q and the business contractor licence are searchable at esasafe.com. Verify both before hiring.
How much does a panel upgrade cost in Ontario?
In the Renfrew County area, expect:
- 100A → 200A panel upgrade: $2,000–$4,000
- 60A → 200A service upgrade (more extensive): $2,500–$5,000
These ranges typically include panel hardware, labour, and ESA permit and inspection fees — confirm whether permit fees are included when comparing quotes. Utility-side work (Hydro One service disconnect and reconnect) is a separate cost not controlled by your electrician and may add to the total. See the Electrician Cost Guide for a full breakdown.
What electrical work requires a permit in Ontario?
An ESA permit is required for all significant electrical work, including:
- Any new electrical circuit
- Panel upgrades or replacement
- Service entrance work or service upgrade
- EV charger (EVSE) installation
- Swimming pool or hot tub electrical connections
- Home additions or renovations involving new wiring
- Generator transfer switch installation
- Solar photovoltaic (PV) grid-tie connections
Replacing like-for-like outlets, switches, or light fixtures does not typically require a permit. When in doubt, ask your licensed electrician or consult the ESA directly at esasafe.com.
Can I do my own electrical work in Ontario?
Homeowners can perform electrical work on their own principal residence and apply for an ESA homeowner permit. Important conditions:
- The property must be your own home — not a rental property or a home being flipped or renovated for immediate resale
- You must perform the work yourself — a homeowner permit cannot be used to hire an unlicensed person
- ESA inspection is required before the work is covered or concealed
For complex work — panel upgrades, service changes, or anything involving the main service entrance — a licensed electrician is strongly recommended even when a homeowner permit is technically available. The stakes are high and errors can be dangerous or costly to correct.
How do I verify an electrician's ESA licence?
Go to esasafe.com and search using the electrician's name or licence number. Verify two credentials separately:
- Individual Certificate of Qualification (C of Q) — confirms the person is qualified to perform electrical work
- Electrical Contractor Licence — confirms the business is authorized to perform electrical work for hire
Both must be current and active. An electrician with a personal C of Q who works for an unlicensed business is not authorized to perform electrical work for compensation — and work performed in that context is uninsured and uninspected.
What grants are available for electrical upgrades in Ontario?
Several programs are potentially relevant for Renfrew County homeowners undertaking electrical upgrades:
- Canada Greener Homes Loan: Interest-free financing for energy efficiency upgrades including electrical work required for heat pump or EV charger installation
- Ontario Home Efficiency Rebate Plus (HER+): Rebates for heat pumps and related electrical upgrades through participating utilities
- Oil-to-Heat-Pump Affordability (OHPA): For households converting from oil heating to heat pump systems — covers associated electrical upgrades
- IESO Save on Energy: Various rebate programs for electric heating and residential efficiency upgrades
- Net Metering: For solar PV systems — not a grant but reduces electricity bills through grid export credits
See the Grants and Rebates section of this site for current program details and eligibility criteria.
Does my older home need an electrical panel upgrade?
If your home has a 60-amp panel, upgrading is strongly recommended — and in many cases required by your insurer:
- 60A service is considered obsolete and inadequate for modern residential loads
- Many home insurance companies will not renew or will surcharge policies on homes with 60A service
- Modern appliances, EV chargers, and heat pumps cannot be safely added to a 60A service
If your home has 100-amp service, it may be adequate for a smaller home without high-draw appliances. However, 200A is the recommended standard for homes that include or plan to add EV chargers, heat pumps, induction ranges, or other high-load equipment. Have a licensed electrician assess your current service and load profile before deciding.
What is knob-and-tube wiring and is it a problem?
Knob-and-tube (K&T) wiring is an early electrical system found in many Renfrew County homes built before approximately 1945 — this includes significant amounts of housing in older Pembroke neighbourhoods, rural farmhouses, and heritage properties throughout the county.
K&T uses separate hot and neutral conductors supported by ceramic knobs and routed through ceramic tubes where they pass through framing. Key characteristics:
- No ground wire — does not meet modern electrical code requirements for grounded circuits
- Deteriorating insulation — original cloth or rubber insulation breaks down over decades, increasing fire risk
- Insurance concerns — most Ontario home insurers now require K&T removal as a condition of coverage or will refuse to insure homes with active K&T circuits
Knob-and-tube that has been properly deactivated and replaced poses no ongoing concern. Active K&T circuits should be assessed promptly by a licensed electrician, particularly before undertaking any renovation that might disturb or add load to them.
