Homeowners usually want the second kind when buying an older house, when an insurer questions the wiring, before a major renovation, or after a flood, fire or storm. In Ontario, ESA retired its ElecCheck home program and now points homeowners to an Electrical System Safety Assessment done by a Licensed Electrical Contractor.
Either way, the outcome is a clearer picture of the panel, grounding, wiring and protective devices, and a list of corrections ranked by urgency.
When to book an electrical inspection: buying a home, insurance requests and renovations
ESA lists typical reasons for a private assessment: obtaining home insurance, real estate transactions and conforming to local by-laws, among others. It describes the Electrical System Safety Assessment as a review of a home's wiring and devices to identify hazards that could lead to a fire or a shock.
- Your offer on an older house is conditional on inspections, and you want a specialist to review the electrical system.
- Your insurer or broker asks for a written assessment because of knob-and-tube, aluminum wiring or an old fuse panel.
- You are planning a renovation, a basement suite, a heat pump or an EV charger and need to know whether the panel and circuits can take it.
- Water, fire, smoke or a storm has reached the panel, the wiring or the outlets.
- Breakers trip often, lights flicker, outlets feel warm, or you notice a burning smell.
- The house you just bought shows visible amateur work: loose cables, open boxes, extension cords used as permanent wiring.
- A rental unit, secondary suite or plex you own needs a documented check for tenants, a lender or the municipality.
Electrical inspection of permitted work: ESA, the RBQ and Technical Safety BC
In Ontario, ESA inspects work reported through a notification. The Licensed Electrical Contractor files it before starting, the installation is inspected before it is concealed, and ESA issues a Certificate of Acceptance to whoever filed once the work passes. ESA's own General Inspections are now limited to Fire Code compliance, which concerns multi-unit dwellings, so a buyer who wants an overall check of a house hires a contractor instead.
In Quebec, the RBQ oversees electrical installations, whose rules are set out in chapter V, Electricity, of the Construction Code. The contractor must declare to the RBQ the construction work subject to that chapter, except work included in a connection request to an electricity distributor and work of no more than 10 kW that doesn't require replacing or adding wiring. In British Columbia, Technical Safety BC issues permits in most areas, while a few municipalities issue their own; the contractor's field safety representative declares compliance and requests an inspection after each phase, and at least once within 180 days of the permit being issued.
What a home electrical safety inspection checks: panel, grounding, wiring and alarms
A visual assessment has limits. ESA notes that its general inspections don't include wiring behind walls, in attics or anything else concealed at the time of the visit, and a private assessment faces the same reality: the electrician judges hidden cable from the panel, the boxes and the spaces that are open.
- Service and panel: the service entrance, meter base and panel, breaker or fuse sizes matched to the wire, signs of heat, rust or water, and a legible circuit directory.
- Grounding and bonding: the grounding conductor and its connection, and the bonding of metal piping where required.
- Wiring type and condition: knob-and-tube, aluminum branch wiring, cloth-insulated cable, amateur splices and extension cords used as permanent wiring.
- Receptacles and switches: ungrounded or miswired receptacles, loose or warm devices and damaged cover plates.
- GFCI and AFCI protection: whether ground-fault protection is in place near water and outdoors and arc-fault protection where the code expects it, and whether the devices trip when tested.
- Smoke and carbon monoxide alarms: presence, location and age, and whether they are hardwired or battery-powered.
- Exterior and special circuits: outdoor outlets, pool and hot tub equipment, and the feed to a garage or shed.
Electrician's inspection or general home inspection: what a buyer needs
A general home inspector looks at the whole house in one visit, from the roof to the foundation, and notes visible electrical concerns such as an old panel, two-prong outlets or missing ground-fault protection, often recommending that a licensed electrician look further. The electrician's assessment goes deeper on that one system: removing the panel cover where it is safe to do so, testing receptacles and protective devices, identifying the wiring type circuit by circuit, and judging what the corrections would involve. For an older house, the two work well together, as long as the electrician visits within the inspection period set in your offer.
Electrical inspection after a flood, fire or storm
Water and heat damage electrical equipment in ways you can't always see. Hydro-Québec states that if it interrupted your service, only a master electrician can ask to have it restored, and that if water got into the home without a service interruption, you should consult a master electrician before turning the power back on. In Ontario, repairs after a storm go to a Licensed Electrical Contractor, and ESA notes that one of its inspectors confirms the power can be reconnected.
After a fire, have the circuits near the damaged area, and any soaked by firefighting water, assessed before they are used again, and keep the electrician's written findings for your insurance claim. Until then, stay away from a wet panel and let the electrician and the utility decide what can be switched back on.
Your electrical inspection report: priorities, repairs and next steps
A useful report lists what was checked, what was found and where, with photos, and sorts the findings: hazards to correct right away, such as overheating connections or a damaged panel; code deficiencies to fix soon; and upgrades worth planning, such as adding arc-fault protection or replacing old circuits during a future renovation. It should also say what could not be seen.
Corrections are regulated electrical work, not something to tackle yourself. ESA notes that when a Licensed Electrical Contractor finds deficiencies during an assessment, it works with the homeowner to correct them, and the work has to be reported to ESA through a notification. Ask for a written scope for each item, keep the report with your permit papers, and send your insurer or buyer the proof it asked for once the repairs are inspected.
Electrical Inspections: frequently asked questions
Does ESA still do home electrical inspections for buyers?
Not as a general service. ESA decommissioned its ElecCheck program effective April 4, 2022, and its General Inspections now cover Fire Code compliance only. For a purchase, insurance or a by-law requirement, ESA says a Licensed Electrical Contractor can perform an Electrical System Safety Assessment.
My insurer wants an electrical inspection. What should I ask for?
Ask the insurer exactly which document it needs and what worries it. ESA notes that many insurers won't cover homes with knob-and-tube, and that some require an ESA inspection before insuring a home with aluminum wiring. A licensed electrician's written assessment, followed by corrections that are notified and inspected, is the usual way to answer.
Who does electrical inspections in Quebec?
For new work, the contractor, licensed through the CMEQ, must apply the Construction Code and declares the work to the RBQ when the rules require it. For a safety assessment of an existing home, hire a master electrician whose firm holds a licence, and ask for a written report.
Can an electrical inspection see inside the walls?
Not directly. The electrician judges hidden wiring from the panel, the boxes, the attic and the basement, and may recommend opening a wall where something looks wrong. A good report says what could not be examined.
Is a home inspector's report enough for the wiring?
It flags visible concerns, but a home inspector is a generalist. For an older home, or when the report raises an electrical issue, a licensed electrician's assessment goes further and describes what the corrections involve.
