Licensed electricians for residential electrical work
Published March 5, 2026
Complete Ontario electrician guide: average costs in CAD, ESA requirements, how to hire a licensed 309A electrician, EV charger installation, common wiring problems, and available rebates.
Whether you own a century home in Toronto's Cabbagetown neighbourhood or a postwar bungalow in Kitchener, electrical work is one of the most consequential investments you will ever make in your property. Done right, it keeps your family safe, raises your home's resale value, and positions your household for a decade of rising electricity demands — from electric vehicles to heat pumps to home offices that did not exist when most Ontario panels were sized. Done carelessly or illegally, it can void your insurance, trigger a failed ESA inspection at closing, or — in the worst case — start a fire behind drywall that nobody sees until it is too late.
This guide was written from the perspective of a licensed 309A Construction and Maintenance Electrician with more than two decades of field experience across the Greater Toronto Area, Southwestern Ontario, and Eastern Ontario. Every dollar figure is in Canadian dollars, every regulation reference is Ontario-specific, and every recommendation reflects the realities of our housing stock, our climate, and the Electrical Safety Authority (ESA) rules that govern all electrical installations in the province.
Ontario's residential electrical landscape is under more pressure than at any point in the province's history, and several forces are converging at once.
Aging housing stock. Statistics Canada data shows that more than 1.5 million Ontario homes were built before 1975. A significant share of those properties still contain aluminum branch-circuit wiring (installed roughly between 1965 and 1976), knob-and-tube wiring (pre-1950 construction), or original 60-ampere service panels that were designed for an era when a home's heaviest electrical load was a clothes dryer. In cities like Hamilton, St. Catharines, Kingston, and the older neighbourhoods of Toronto and Ottawa, it is common to open a panel and find a mix of Federal Pacific Stab-Lok breakers, double-tapped circuits, and wiring that has not been touched in half a century.
EV adoption. Ontario now has more than 200,000 registered battery-electric and plug-in hybrid vehicles on the road, and that number is accelerating. Every Level 2 home charger requires a dedicated 40-ampere or 50-ampere circuit and, in most homes built before 2010, a panel upgrade or at minimum a load-calculation review. Electricians across the GTA report that EV charger installations now represent 15 to 20 percent of their residential work.
Electrification and heat pumps. Provincial and federal incentive programs are pushing homeowners toward cold-climate heat pumps, heat-pump water heaters, and induction cooktops — all of which draw significant amperage. A household that once peaked at 80 amps of demand can easily exceed 150 amps after adding a heat pump and an EV charger, which means the 100-ampere panel that was "fine" last year is suddenly undersized.
Smart home and home-office demand. The permanent shift to hybrid work has created sustained demand for dedicated home-office circuits, structured data cabling, whole-house surge protection, and upgraded lighting. Smart-home automation — from smart panels like Span to whole-house generators with automatic transfer switches — adds another layer of complexity that requires licensed installation.
Safety. Electrical fires cause more than one billion dollars in Canadian property damage annually, according to the Office of the Fire Marshal. Ontario averages seven to ten residential electrocution deaths each year. The 2013 Toronto ice storm and the 2022 Ottawa derecho both triggered massive spikes in generator installations — many of them performed under emergency conditions where corners are tempting to cut. Understanding your home's electrical system is not optional; it is a safety imperative.
Regulatory environment. The Electrical Safety Authority (ESA) governs all electrical installations in Ontario. Unlike most other provinces, Ontario has a unique homeowner provision that allows you to perform your own electrical work under certain conditions and with an ESA permit — but the rules are strict and the inspection process is rigorous. Knowing where that line falls can save you thousands of dollars or keep you out of serious trouble.
This guide will walk you through every major category of residential electrician work, give you real 2026 pricing for the Ontario market, explain the permit and code requirements, help you evaluate contractors, and flag the most common problems lurking in Ontario homes. If you are planning any electrical project — or simply want to understand what you are paying for when an electrician hands you a quote — this is the resource you need.
Residential electrician services fall into several broad categories. Understanding which category your project belongs to will help you get accurate quotes, pull the right permits, and set realistic timelines.
This is the most common reason homeowners call an electrician. Typical repair work includes:
Repair work typically does not require an ESA permit if no new wiring is being installed and no circuits are being added. However, any work that modifies the wiring or adds circuits crosses into permit territory.
Your electrical panel is the heart of your home's electrical system. It receives power from the utility, distributes it across branch circuits, and provides overcurrent protection through breakers or fuses. Common panel-related work includes:
Panel upgrades almost always require an ESA permit, a utility disconnect and reconnect, and a final ESA inspection before the utility will restore service.
New circuit installation covers a wide range of projects:
Lighting work ranges from simple fixture swaps to complete redesigns:
Electric vehicle charger installation has become one of the fastest-growing segments of residential electrical work in Ontario. The standard residential installation involves:
Homeowners in the GTA should be aware that some older neighbourhoods in Toronto, Hamilton, and Ottawa have narrow driveways or detached garages that require longer cable runs, increasing installation costs significantly.
After the 2013 Toronto ice storm left some neighbourhoods without power for more than a week, and the 2022 Ottawa derecho caused similar extended outages, generator demand in Ontario has remained permanently elevated. Options include:
Several categories of residential electrical work require specialized expertise:

Electrician rates vary significantly across Ontario. Understanding your region's labour market helps you evaluate quotes more accurately.
Greater Toronto Area ($95 – $135/hour). The GTA — including Toronto, Mississauga, Brampton, Markham, Vaughan, Richmond Hill, and Oakville — commands the highest electrician rates in the province. This reflects higher operating costs, licensing fees, parking and access challenges in urban condos and narrow-lot houses, and sustained demand driven by the region's construction and renovation activity. In downtown Toronto, expect to pay a premium for projects in older homes where access is difficult and parking adds to the electrician's overhead.
Southwestern Ontario ($80 – $115/hour). Cities like London, Kitchener-Waterloo, Cambridge, Guelph, and Windsor fall into this range. Strong demand from the region's growing tech sector and new housing developments keeps rates competitive but lower than the GTA. Windsor's proximity to the US border and the Stellantis/LG EV battery plant has created localized demand spikes for EV-related electrical work.
Eastern Ontario ($75 – $110/hour). Ottawa, Kingston, Belleville, Cornwall, and Peterborough. Ottawa rates approach GTA levels for complex work, but smaller cities in the region offer more competitive pricing. The Eastern Ontario market has a higher proportion of older homes, which means electricians in this region tend to have deep experience with aluminum wiring, knob-and-tube, and heritage property considerations.
Northern Ontario ($70 – $105/hour). Sudbury, Thunder Bay, Sault Ste. Marie, North Bay, Timmins, and Kenora. Lower hourly rates but potentially higher project costs due to travel time, material shipping delays, and fewer competing contractors. In remote communities, a single qualified electrician may serve a wide area, and scheduling can require weeks of advance planning.
| Metric | Amount |
|---|---|
| National Average (Low) | $150 |
| National Average (High) | $499 |
| Lowest Reported | $127 |
| Highest Reported | $550 |
| Cities with Data | 2,047 |

Understanding the variables that drive electrical project pricing helps you budget accurately and evaluate competing quotes on an apples-to-apples basis. Here are the ten most significant cost factors for Ontario homeowners.
The single biggest cost driver. A home built in the 1990s with copper NMD-90 wiring and a 200A panel is a straightforward canvas for additional work. A 1920s Toronto home with knob-and-tube, a 60A fuse box, plaster-and-lath walls, and no ground wires is an entirely different proposition. Every aspect of the job takes longer when the existing infrastructure is outdated or non-compliant.
If your current panel has spare breaker slots and adequate amperage, adding a new circuit is relatively inexpensive. If the panel is full — or worse, undersized for your total load — you may need a panel upgrade before the original project can even begin. This can add $2,500 to $4,500 to a project that seemed simple in the planning stage.
An electrician working in an unfinished basement with exposed joists can run cable in a fraction of the time it takes to fish wire through finished walls and ceilings. Attic access, crawl space height, and the presence of insulation all affect labour time. In multi-storey homes, running a new circuit from the basement panel to a second-floor bedroom may require opening walls on multiple floors.
A single outlet installation might take 45 minutes. A whole-house rewire can take two to three weeks. Scope affects not just total cost but also the type of permit required, the number of inspections, and the logistical complexity of the work.
Copper wire prices have increased approximately 30% since 2020 and remain elevated. For large projects — whole-house rewires, panel upgrades with extensive branch-circuit work — material costs represent 25% to 40% of the total project price. The type of wire (NMD-90, TECK cable, armoured cable), the gauge required (14 AWG for 15A circuits through 6 AWG for 50A circuits), and the length of runs all affect material costs.
Emergency calls — evenings, weekends, holidays, or "the power is out right now" situations — typically carry a premium of 1.5x to 2x the standard hourly rate. Planning your electrical work during normal business hours and booking in advance can save 30% to 50% compared to emergency rates.
Every electrical project that involves new wiring, new circuits, panel modifications, or fixed equipment installation requires an ESA permit in Ontario. Permit fees range from $75 to $250+ depending on the municipality and scope. The ESA inspection fee is separate and typically runs $100 to $200. Your electrician usually handles the permit application and schedules the inspection, but these costs are passed through to you.
Electrician demand in Ontario follows predictable seasonal patterns. Summer (June through August) sees peak demand for air conditioning circuits, outdoor lighting, pool and hot tub wiring, and EV charger installations timed to summer road trips. Late fall (October through November) brings a surge in generator installations as homeowners prepare for winter storms. Scheduling work during the quieter winter months (January through March, excluding emergency storm work) can sometimes yield faster availability and more competitive pricing.
Projects involving aluminum wiring, knob-and-tube wiring, asbestos-containing materials (common in pre-1980 Ontario homes as wire insulation or panel gaskets), or heritage designations add cost due to specialized techniques, additional safety precautions, and sometimes additional permits from municipal heritage committees.
Ontario's 13% Harmonized Sales Tax applies to all electrician labour and materials. On a $4,000 panel upgrade, that is $520 in tax. Some homeowners forget to factor HST into their budget, which leads to sticker shock when the final invoice arrives.
Ontario's four distinct seasons create specific patterns in residential electrical demand. Timing your project to align with — or strategically avoid — these patterns can affect both cost and contractor availability.
Spring is when most Ontario homeowners begin planning renovation projects after the winter pause. Demand for electricians begins to climb in April and accelerates through May. Common spring electrical projects include:
Summer is the busiest season for Ontario electricians. Extended daylight hours allow for longer workdays, and several high-demand project categories converge:
Expect longer wait times (two to four weeks) for non-emergency summer work in the GTA. Booking in May for a June or July start is advisable.
Fall brings a shift in focus from outdoor work to winter preparation:
Winter is the quietest season for planned electrical work in Ontario, which creates opportunities for homeowners:
Ontario has one of the most rigorous electrical safety regimes in North America. Understanding the regulatory landscape protects you legally, keeps your insurance valid, and ensures your work passes inspection.
The ESA is the sole authority responsible for electrical safety in Ontario. It is a delegated administrative authority (not a government department) that operates under the authority of the Electricity Act, 1998. The ESA:
The OESC is the technical standard governing all electrical installations in Ontario. It is based on the Canadian Electrical Code (CEC) but includes Ontario-specific amendments. The current edition incorporates requirements for:
Ontario requires all electricians performing work to hold valid certification:
Both are compulsory trades in Ontario, meaning it is illegal to perform electrical work without one of these certifications (with the homeowner exception described below). You can verify any electrician's licence through the SkilledTradesOntario online registry.
In addition to individual electrician licences, electrical contracting businesses must hold an ECRA (Electrical Contractor Registration Agency) licence, now administered by the ESA. This ensures the business carries appropriate insurance, employs licensed electricians, and is accountable to the ESA for the quality and safety of its work.
Ontario is unique in Canada in allowing homeowners to perform their own electrical work under specific conditions:
In practice, this means a handy homeowner can legally install a new outlet, run a circuit, or even upgrade a panel — provided they pull the permit, do the work to code, and pass inspection. However, the ESA inspection failure rate for homeowner-permitted work is significantly higher than for work done by licensed electricians, and the cost of correcting failed inspections often exceeds what a professional would have charged in the first place.
Unpermitted electrical work in Ontario carries serious consequences:
Choosing the right electrician is one of the most important decisions you will make during a home improvement project. Here is a systematic approach to finding and vetting qualified electricians in Ontario.
Before anything else, confirm that the electrician holds a valid 309A or 442A certificate through the SkilledTradesOntario public registry. Then confirm that their employer holds a valid ECRA/ESA contractor licence. Both verifications take less than five minutes online and are non-negotiable.
A reputable electrical contractor will carry:
Ask for certificates of insurance and verify they are current. If an uninsured electrician is injured in your home, you could face personal liability.
Not all electricians have the same skill set. If your project involves aluminum wiring remediation, look for an electrician who has completed hundreds — not dozens — of aluminum wiring projects. If you need a standby generator installed, find a contractor who is an authorized dealer and installer for a major generator brand (Generac, Kohler, Briggs & Stratton). Specialization matters.
For any project over $500, obtain at least three written quotes. Each quote should clearly specify:
Ontario electricians typically use one of two pricing models:
Walk away from any electrician who:

Ontario's homeowner provision creates a unique situation in Canadian residential electrical work. Understanding where the DIY line falls — both legally and practically — can save you money on simple tasks while keeping you safe on complex ones.
Under the homeowner provision, you can legally perform electrical work in your own primary residence provided you obtain an ESA permit and pass inspection. In practice, this is most appropriate for:
While the homeowner provision technically allows you to perform almost any electrical work in your own home, certain projects are dangerous, complex, or code-intensive enough that hiring a licensed electrician is the only sensible choice:
Ontario averages seven to ten residential electrocution deaths per year, plus hundreds of non-fatal electrical injuries. Electrical fires account for a disproportionate share of residential fire damage. The most common contributing factors are:
If you choose to do your own electrical work under the homeowner provision, invest in education. The ESA offers homeowner resources, and several Ontario community colleges offer evening courses in basic residential wiring. Never work on live circuits, always use a non-contact voltage tester, and treat every wire as live until you have personally verified it is de-energized.
Ontario's housing stock spans more than 150 years of construction, and each era brought its own wiring methods, materials, and standards. Here are the ten most common electrical problems that Ontario electricians encounter.
Between approximately 1965 and 1976, aluminum wire was widely used for 15A and 20A branch circuits in Ontario homes as a cost-saving alternative to copper during a period of high copper prices. The problem is not the aluminum wire itself — it is a perfectly adequate conductor — but the connections. Aluminum expands and contracts more than copper with temperature cycling, and it oxidizes when exposed to air, creating high-resistance connections that generate heat.
Identification: Look at the wiring visible in your panel or at an accessible outlet. Aluminum wire is silver-coloured (copper is, obviously, copper-coloured). The cable sheathing may be stamped "AL" or "ALUMINUM."
Risk level: The US Consumer Product Safety Commission (CPSC) found that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions at outlets than homes with copper wiring. Canadian data mirrors this finding.
Solutions: COPALUM crimp connectors (gold standard, requires specialized tool), AlumiConn set-screw connectors (approved alternative), or full copper rewire.
Knob-and-tube (K&T) is the oldest wiring method found in Ontario homes, common in pre-1950 construction across Toronto, Hamilton, Kingston, Ottawa, and other cities with significant Victorian and Edwardian housing stock. K&T uses individual conductors (hot and neutral — no ground) run through porcelain knobs and tubes.
Problems: No grounding, insulation degradation over 70+ years, inability to safely blow insulation into walls containing K&T (fire risk), and the tendency of previous homeowners to extend K&T circuits improperly.
Insurance impact: Many Ontario insurers will not cover homes with active K&T wiring, or they charge a significant premium.
Federal Pacific Electric (FPE) panels with Stab-Lok breakers were installed in hundreds of thousands of Ontario homes between the 1950s and 1980s. Testing has consistently shown that a significant percentage of FPE Stab-Lok breakers fail to trip during overcurrent conditions — the one thing a breaker absolutely must do.
Recommendation: Immediate panel replacement. This is not a "monitor and wait" situation. If you have a Federal Pacific panel, budget for a replacement as a priority safety investment.
Older Ontario homes were designed for a fraction of today's electrical load. A home built in the 1960s might have four or five circuits serving the entire house — a number that was adequate when the heaviest kitchen load was a toaster. Today, that same kitchen might have a dishwasher, microwave, range hood, instant hot water tap, countertop convection oven, and a coffee machine, all sharing a single 15A circuit.
Symptoms: Frequently tripping breakers, warm outlet cover plates, dimming lights when appliances cycle on.
Two-prong (ungrounded) outlets are common in Ontario homes built before the 1960s. While a two-prong outlet is not inherently dangerous, it provides no equipment grounding — meaning there is no safe path for fault current and no protection for sensitive electronics.
Solutions: Install grounding conductor to each outlet (ideal but expensive in finished homes), replace with GFCI-protected outlets (provides personal protection but not equipment grounding — code-compliant with labelling), or rewire the circuit.
The Ontario Electrical Safety Code requires GFCI (Ground Fault Circuit Interrupter) protection for all receptacles in kitchens (within 1.5 metres of a sink), bathrooms, outdoors, garages, unfinished basements, and near laundry sinks. Many older Ontario homes lack this protection entirely.
Cost to correct: $150 to $250 per location for a GFCI receptacle, or $200 to $400 for a GFCI breaker protecting an entire circuit.
Occasional flicker during utility voltage fluctuations is normal. Persistent flickering, especially concentrated in one area of the house, warrants investigation. Common causes include loose connections (especially in homes with aluminum wiring), a failing breaker, a deteriorated neutral connection at the panel or meter, or a utility-side problem.
A full panel — every breaker slot occupied and total connected load near the panel's rated capacity — is not dangerous in itself, but it means you cannot add any new circuits without a panel upgrade or sub-panel installation. This is one of the most common surprises homeowners encounter when they request a "simple" outlet addition or EV charger installation.
Ontario's freeze-thaw cycles can cause moisture infiltration into outdoor outlet boxes, leading to nuisance GFCI tripping. Properly rated in-use weatherproof covers (not just weather-resistant covers) and correct box installation with drainage provisions are the solution.
During past renovations, junction boxes (where wires are spliced) are sometimes drywalled over, making them inaccessible. This violates the OESC, which requires all junction boxes to remain accessible without removing building finishes. Buried junction boxes cannot be inspected, maintained, or identified as the source of a problem when circuits fail.
Electrical upgrades can represent a significant investment, but several programs can offset costs for Ontario homeowners.
The federal iZEV (Incentives for Zero-Emission Vehicles) program provides rebates on eligible electric vehicles, and some municipalities and utilities offer rebates on Level 2 charger hardware or installation. Check with your local utility (Toronto Hydro, Hydro One, Alectra, London Hydro, Ottawa Hydro, etc.) for current incentive programs, as these change frequently.
While primarily focused on gas efficiency, Enbridge programs sometimes include electrical components — particularly when upgrading to an electric heat pump or a hybrid HVAC system. The Home Efficiency Rebate Plus program may cover a portion of costs when electrical upgrades are part of a broader energy-efficiency improvement.
The federal Canada Greener Homes programs (grant and interest-free loan) cover certain electrical upgrades when they are part of an approved energy-efficiency improvement — particularly heat pump installations and solar panel systems that require panel upgrades.
If electrical modifications are required to improve home accessibility for a senior or person with a disability — such as improved lighting, accessible outlet heights, or powered door operators — the federal HATC may provide a non-refundable tax credit for eligible expenses.
Completing aluminum wiring remediation, replacing a Federal Pacific panel, upgrading from a fuse box to a breaker panel, or replacing knob-and-tube wiring can result in meaningful reductions in your homeowner's insurance premiums. Some Ontario insurers offer 5% to 15% discounts for homes with updated electrical systems. Contact your insurer before starting the work to understand what documentation they need to apply the discount.
While not a rebate program, the return on investment from replacing incandescent or fluorescent lighting with LED is worth noting. A typical Ontario home converting 30 light fixtures to LED can save $200 to $400 per year in electricity costs, meaning the conversion pays for itself in one to three years while reducing your carbon footprint.
Some electrical contractors offer financing on major projects like panel upgrades and whole-house rewires. Terms vary, but 12-month interest-free financing is available from some Ontario contractors through third-party lenders. Always compare the total cost of financed work against paying out of pocket — contractor-arranged financing sometimes comes with higher base pricing.
Electrical work touches every aspect of your Ontario home — from safety and insurance compliance to energy efficiency and property value. Whether you are dealing with aluminum wiring in a 1970s Mississauga split-level, upgrading a century-old Toronto panel to support an EV charger, or wiring a standby generator in Ottawa before the next ice storm, the fundamentals remain the same: hire licensed professionals, always pull permits, and never compromise on the quality of work that protects your home and family.
The Ontario electrical landscape is changing rapidly. EV adoption, heat pump electrification, smart-home technology, and an aging housing stock are creating unprecedented demand for qualified electricians. Projects that seemed optional five years ago — panel upgrades, whole-house surge protection, dedicated home-office circuits — are now essential infrastructure for a modern Ontario household.

Electrician hourly rates in Ontario range from $70 to $135 per hour depending on the region, with the GTA commanding the highest rates ($95 to $135/hour) and Northern Ontario the lowest ($70 to $105/hour). Most electricians charge a minimum service call fee of $85 to $150, which typically covers the first hour. Many projects, including panel upgrades, EV charger installations, and rewiring, are quoted at a flat rate rather than hourly.
Yes, almost all electrical work in Ontario requires an ESA (Electrical Safety Authority) permit. This includes adding new outlets, running new circuits, upgrading panels, installing EV chargers, wiring pools or hot tubs, installing generators, and any work that modifies the permanent wiring of your home. Simple like-for-like replacements (swapping one outlet for another identical outlet, replacing a light switch) do not require a permit. When in doubt, contact the ESA — the consequences of unpermitted work (voided insurance, fines, issues at resale) far outweigh the cost of a permit.
Yes, Ontario's homeowner provision allows you to perform electrical work in your own primary residence provided you obtain an ESA permit before starting, perform the work to Ontario Electrical Safety Code standards, and pass the ESA inspection. You cannot do electrical work on rental properties you own, on other people's homes, or for compensation. While this provision technically allows you to perform complex work like panel upgrades, in practice, dangerous tasks involving live service entrance conductors should be left to licensed professionals.
Check the wiring visible in your electrical panel — aluminum wire is silver or grey, while copper is copper-coloured. The cable sheathing may be stamped "AL" or "ALUMINUM." If your home was built between approximately 1965 and 1976, there is a strong probability it contains aluminum branch-circuit wiring. An electrician can confirm in minutes. Many Ontario insurance companies ask about aluminum wiring during the application process and may require remediation or charge higher premiums for homes with unremediated aluminum wiring.
A typical 100A to 200A panel upgrade in an Ontario home takes one full day (6 to 8 hours) of on-site work by a licensed electrician, plus an ESA inspection visit (usually within one to two weeks). Total elapsed time from permit application to final ESA approval is typically two to four weeks. Your power will be off for four to six hours during the upgrade while the utility disconnects and reconnects service. If the meter base, weatherhead, or service entrance cables also need replacement (common in older homes), add a second day and additional utility coordination time.
A complete Level 2 EV charger installation in Ontario typically costs $1,500 to $3,500 for the electrical work alone, plus $500 to $1,200 for the charger unit itself. If your panel requires an upgrade to accommodate the additional 40A or 50A load, add $2,500 to $4,500 for the panel upgrade. Total all-in cost ranges from $2,000 for a straightforward installation in a home with a 200A panel and a short circuit run, to $8,000+ for a full panel upgrade combined with a long run to a detached garage.
Knob-and-tube wiring that is original, unmodified, and in good condition is not inherently dangerous — it was a code-compliant installation method for its era. However, after 70 to 100+ years, insulation deterioration, previous improper modifications, lack of grounding, and the inability to safely install blown insulation in walls containing K&T make it a significant risk factor. Most Ontario insurance companies will not provide standard coverage for homes with active K&T wiring. The practical recommendation is replacement, prioritized by floor (start with the floor that has the most circuits) and by accessibility (unfinished areas first).
After your electrician (or you, under the homeowner provision) completes the permitted work and calls for inspection, an ESA inspector visits the site. The inspector verifies that the work complies with the Ontario Electrical Safety Code, checks connections, grounding, bonding, overcurrent protection, and workmanship. If the work passes, the ESA issues a Certificate of Acceptance. If it fails, the inspector issues a deficiency notice listing required corrections, and a re-inspection is scheduled after corrections are made. Re-inspection fees may apply. ESA inspection records are publicly searchable online — a fact that is relevant at resale.
Visit the SkilledTradesOntario website and use the public registry to search for the individual electrician's 309A or 442A certificate. For the contracting company, search the ESA's ECRA/ESA licensed contractor database. Both searches are free and take less than five minutes. Any legitimate electrician will be happy to provide their licence number and employer's ECRA number when asked.
Arc-fault circuit interrupters (AFCIs) are breakers that detect dangerous electrical arcs — the type of sparking that can occur in damaged wiring, loose connections, or pinched cords — and trip the circuit before the arc can ignite surrounding materials. The current Ontario Electrical Safety Code requires AFCI protection on most 15A and 20A branch circuits in bedrooms and living areas of new construction and major renovations. Existing homes are not required to retrofit AFCI breakers unless the circuits are being modified. However, AFCI protection is a worthwhile safety upgrade, particularly in older homes with aging wiring, at a cost of approximately $50 to $80 per breaker plus installation.
