Common Signs You May Need Electrical Repair
Electrical problems often start with small warning signs before becoming larger failures. An outlet that works intermittently, a breaker that repeatedly trips or lights that flicker when equipment turns on can indicate an electrical fault that deserves proper diagnosis.
​
Contact Antech Electric for electrical repair services if you notice:
-
Circuit breakers repeatedly tripping or refusing to reset
-
Lighting circuits that stop working
-
Burning or unusual electrical smells
-
GFCI outlets that repeatedly trip or will not reset
-
Electrical problems that return after being reset
-
Partial power loss in one room or section of the property
-
Buzzing switches, outlets or panels
-
Electrical faults appearing after renovations, storms or water exposure
-
Warm or discoloured receptacles and switches
-
Dead or intermittent electrical outlets
-
Frequently blown fuses
-
Sparking or visible arcing
-
Flickering or dimming lights
-
Panel overheating or unusual noise
-
Damaged or exposed electrical wiring
Recurring problems should not simply be reset or ignored. A symptom may originate in the device, wiring, circuit breaker, panel, connected equipment or electrical supply.
Accurate electrical repair starts with diagnosis.
​
The same symptom can have several different causes, and each cause may require a different solution. That's why Antech Electric approaches repair calls as troubleshooting problems first and parts-replacement jobs second.
Breaker Keeps Tripping
A breaker that repeatedly trips may be responding to an overloaded circuit, short circuit, ground fault, damaged wiring, defective connected equipment, loose connection or a problem with the breaker itself. Instead of repeatedly resetting it, our electricians evaluate the circuit and relevant equipment to determine why the protective device is operating.
Dead Electrical Outlet
An electrical outlet that suddenly stops working could involve the receptacle itself, a loose connection, a tripped GFCI elsewhere on the circuit, damaged wiring, a breaker issue or loss of power upstream. The outlet you can see is therefore not necessarily where the fault originates.
Flickering or Dimming Lights
Persistent flickering may involve the fixture, switch, dimmer, LED driver, circuit loading, wiring connections or another part of the electrical supply. If several lights or circuits are affected simultaneously, the problem may require a broader electrical assessment.
Partial Power Loss
When one part of a property loses power while the rest remains energized, our electricians can inspect the relevant breakers, circuits, connections and devices to determine where the interruption occurred.
Our diagnostic approach
Depending on the electrical problem, troubleshooting may involve testing voltage, load, continuity, breakers, devices, connections and wiring to isolate the affected portion of the system.
​
Once we identify the likely cause, we explain what we found, what repair we recommend and whether replacement or upgrading should be considered.
​
The objective is to repair the cause—not just temporarily remove the symptom.
Electrical Repairs We Handle
Electrical Panel Repair
Your electrical panel distributes power throughout the property and protects individual circuits. Problems involving the panel can affect one circuit, several circuits or—in more serious situations—the entire property's electrical supply. Not every panel problem requires replacement; when equipment is damaged, obsolete or no longer has sufficient capacity, we explain whether panel replacement or a service upgrade is more practical.

Circuit Breaker Repair
A circuit breaker is designed to interrupt power when certain unsafe electrical conditions occur. Our circuit breaker repair services include troubleshooting breakers that repeatedly trip, will not remain reset, produce unusual heat or noise, supply circuits with intermittent power or begin failing after new equipment or additional electrical loads are introduced.
Related Service: Circuit Breakers & Fuses
Electrical Outlet Repair
Antech Electric provides electrical outlet repair in Toronto and throughout the GTA for houses, condominiums, offices, retail properties and other buildings. Common problems include dead outlets, intermittent power, loose receptacles, GFCIs that will not reset, damaged outlets, unusual heat, buzzing, discolouration and sparking. The outlet displaying the symptom may not contain the fault.
Related Service: Electrical Outlets
Electrical Wiring Repair
Wiring faults can create intermittent power, repeated breaker trips, damaged devices, overheating and potential shock or fire hazards. We address loose connections, damaged conductors, deteriorated insulation, improper alterations, grounding and bonding issues and renovation-related damage. Older wiring does not automatically mean the entire property needs rewiring.
Related Service: Electrical Wiring Installation & Repair
Lighting & Light Fixture Repair
Lighting problems can originate in the fixture, lamp or LED driver, switch, dimmer, wiring, controls or circuit. We provide troubleshooting and repair for flickering fixtures, failed lighting circuits, recessed and pot lights, exterior lighting, security lighting, commercial lighting and emergency lighting.
Related Service: Lighting Installation
Switch, Dimmer & Control Repair
Our electricians troubleshoot electrical controls including standard switches, dimmers, timers, occupancy sensors, smart switches and lighting-control systems. If a switch works intermittently, buzzes, becomes unusually warm or no longer controls the connected device properly, the problem may involve the switch, the connection behind it or the circuit supplying it.
.
GFCI & AFCI Troubleshooting
GFCI and AFCI protective devices are intended to interrupt power when particular unsafe electrical conditions are detected. Repeated tripping or a device that will not reset can indicate a problem involving the protective device, connected equipment or circuit. We determine why protection is operating rather than treating the trip as the problem.
.
Short Circuit & Electrical Fault Repair
Short circuits and other electrical faults can result in breaker trips, partial power loss, sparking, damaged equipment or unreliable circuits. Professional troubleshooting can involve evaluating circuits, wiring, connections, breakers, protective devices and connected loads to isolate the fault. These repairs should not be approached as DIY electrical work.
.
Need Electrical Repair Right Away?
Urgent situations such as burning smells, sparking, hot panels, major power loss and damaged wiring may require immediate attention. Do not touch damaged electrical equipment, exposed conductors or equipment affected by water.
Residential & Home Electrical Repair Services
Antech Electric provides home electrical repair services for detached houses, semi-detached homes, townhouses, condominiums, apartments and multi-unit residential properties throughout Toronto and the GTA.
​
Residential electrical problems vary significantly according to the property's age, wiring, renovation history, panel capacity and connected equipment. Older Toronto properties may contain legacy wiring or electrical alterations completed over several generations of renovations. Mid-century homes throughout the GTA may contain older panels or aluminum branch wiring. Newer homes increasingly place additional electrical demand on circuits through EV chargers, heat pumps, finished basements, smart-home technology and home offices.
​
Our residential electrical repair work includes breaker and circuit troubleshooting, electrical outlet repair, switch and dimmer repair, panel troubleshooting, wiring repair, flickering-light diagnosis, GFCI/AFCI issues, partial power loss, smoke and CO alarm electrical problems, fan electrical troubleshooting, smart controls and renovation-related faults.
​
Whether the problem affects one outlet or several circuits throughout the property, our residential electricians work to determine what failed, why it failed and what repair is appropriate.
Commercial Electrical Repair Services
Electrical failures in commercial buildings can affect employees, tenants, customers, equipment and revenue.
​
Antech Electric provides commercial electrical repair services for offices, retail stores, restaurants, medical and dental offices, commercial plazas, condominium corporations, mixed-use buildings, property-management portfolios, warehouses and other commercial facilities.
​
Commercial repairs can include lighting failures, receptacle problems, tenant electrical faults, breaker and panel issues, equipment circuits, emergency and exit lighting, electrical controls, damaged wiring, distribution problems and intermittent power.
​
Our commercial electricians focus on identifying the affected circuit or system efficiently and developing a repair plan that minimizes unnecessary disruption. Preventive electrical maintenance can also help businesses identify deteriorating equipment and recurring electrical problems before they result in an unexpected outage.
Industrial Electrical Repair & Troubleshooting
Manufacturing facilities, warehouses, distribution centres and industrial properties rely on electrical systems that support equipment, lighting, controls and production.
​
Antech Electric provides industrial electrical repair and troubleshooting for electrical systems within our verified capabilities, including three-phase distribution, industrial panels, equipment power circuits, motor-control electrical circuits, control wiring, facility lighting, grounding and bonding, and recurring electrical faults affecting facility operations.
​
Industrial troubleshooting requires a systematic approach because an apparent equipment problem may originate in the branch circuit, protective device, control circuit, power connection or facility distribution system.
​
Our electricians work with facility personnel to isolate the electrical fault, explain the findings and determine an appropriate repair strategy while reducing unnecessary downtime. Preventive maintenance can also be used to identify electrical deterioration before it results in unplanned production interruption.
24/7 Emergency Electrical Repair Toronto & GTA
Some electrical problems should not wait for a routine appointment.
​
Antech Electric provides 24/7 emergency electrical repair services for urgent residential, commercial and industrial electrical problems throughout Toronto and the GTA.
​
Call for urgent electrical assistance if you notice burning smells, smoke, visible sparking or arcing, a hot electrical panel, exposed or badly damaged wiring, significant partial power loss, electrical equipment affected by water or storm damage, or electrical failures affecting critical commercial or industrial operations.
​
If several neighbouring properties have also lost power, the problem may involve the local electricity distributor rather than your building. If surrounding properties still have power—or the situation includes heat, smoke, sparking, damaged wiring or burning smells—the fault may be specific to your property.
​
Do not touch damaged electrical equipment, exposed conductors or equipment affected by water.

Electrical Repair or Replacement?
Not every electrical problem requires new equipment—and not every damaged component is worth repairing.
​
Antech Electric uses a diagnosis-first approach to determine whether the safest and most practical solution is targeted repair, component replacement or a larger electrical upgrade.
Breaker Repair vs. Panel Replacement
A single faulty breaker or connection in an otherwise suitable panel may require only targeted work. Significant heat damage, deterioration, obsolete equipment or insufficient capacity can make replacement more appropriate.
Outlet Repair vs. Replacement
A dead outlet may originate elsewhere on the circuit, while a physically damaged, overheated or worn receptacle may require replacement.
Circuit Repair vs. Rewiring
An isolated wiring fault can often be addressed without rewiring an entire property. Widespread deterioration or unsafe previous alterations may require a broader solution.
Lighting Repair vs. Replacement
A fixture problem may involve a switch, driver, control or connection. A severely damaged or obsolete fixture may instead be more economical to replace.
Repair vs. Upgrade
Troubleshooting sometimes reveals that the electrical system is operating close to its practical capacity. If the property is also adding EV charging, heat pumps, major appliances, commercial equipment or new circuits, upgrading may address both the immediate problem and future electrical demand.
We explain the condition, available options and reasoning before recommending major replacement.
Electrical repair pricing depends primarily on what has failed and how difficult the fault is to locate.
​
A single damaged receptacle with an obvious cause may require much less diagnostic time than an intermittent problem affecting several circuits.
​
Other cost factors can include accessibility, diagnostic time, replacement components, the number of affected circuits, the condition of existing wiring, whether panel work is involved, required ESA notification or inspection, and whether emergency or after-hours service is required.
​
Instead of publishing broad prices that may not apply to your property, Antech Electric evaluates the actual electrical problem and explains the repair scope and pricing before authorized work proceeds.
Electrical maintenance can help identify problems before they develop into emergency failures.
​
Depending on the property and electrical system, preventive maintenance may include visual examination of electrical equipment, panel and breaker checks, outlet and GFCI testing, review of recurring electrical problems, lighting checks, identification of deteriorated components and recommendations for repair or upgrading.
​
Preventive maintenance can be especially valuable for property managers, commercial buildings, warehouses and industrial facilities where unexpected electrical downtime can disrupt operations.
Ontario Electrical Repair, Licensing & Electrical Safety
Electrical repair in Ontario is governed by applicable requirements of the Ontario Electrical Safety Code.
​
The current 2024 Ontario Electrical Safety Code is the 29th Edition and became effective May 1, 2025. It incorporates the Canadian Electrical Code, Part I together with Ontario-specific amendments.
​
Customers hiring someone to perform electrical work should verify that the business is an ECRA/ESA Licensed Electrical Contractor. ESA regulates electrical contractor and Master Electrician licensing in Ontario.
​
Antech Electric operates as an ECRA/ESA Licensed Electrical Contractor and completes electrical repair work in accordance with applicable Ontario Electrical Safety Code requirements.
​
Depending on the work being performed, an ESA Notification of Work may be required. Ontario's electrical code contains specific notification requirements as well as situations in which a notification is not required, so the requirement should be determined according to the actual scope rather than assuming every service call is identical.
​
Where notified work is reviewed and passes, ESA can issue a Certificate of Acceptance.
