Why is only my house without power?

A single-house outage is different from a street outage. If the whole home is dark but the houses around you are lit, the fault may be at the service connection, meter base, main disconnect, panel, or underground/overhead supply to your property. Treat it as urgent, especially if you heard a pop, smell burning, see damage at the mast, or the meter area looks hot, loose, or wet.

First, confirm whether it is a utility outage or only your property

First, check the simplest evidence before calling anyone: look outside, ask a neighbour, and check your local utility’s outage map if your phone still has data. A true area outage usually affects more than one home, one side of the street, or a wider pocket of the neighbourhood.

In the GTA, your utility depends on where the house is. It may be Toronto Hydro, Alectra, Hydro One, Oshawa Power, Elexicon, Oakville Hydro, or Burlington Hydro. If the map shows an outage at your address, report it to the utility and wait for restoration updates. An electrician cannot restore power if the utility’s feeder, transformer, service drop, or underground supply is out.

Do these checks from a safe place:

• Look at the streetlights, porch lights, and neighbouring windows.
• Ask one immediate neighbour on each side if they have power.
• Check whether your garage, shed, or detached building is out too, but do not assume that proves a utility outage.
• Look at the utility outage map for your address or postal code.
• If you have overhead wires, look for a pulled service mast, fallen branch, arcing, or a hanging wire. Stay well away.

If only one room or one area is out, that is a different problem. See why one room lost power or why half a house can lose power for those more localized symptoms. This page is about the whole house being out while nearby homes still have power.

Call the utility for supply-side trouble, and call a licensed electrician for house-side equipment

Call the utility when the problem appears to be on the supply side, and call a licensed electrician when the issue is in equipment that belongs to the property. The tricky part is that the meter area is a boundary zone: the utility controls the meter and connection, while the homeowner is usually responsible for equipment such as the service mast, meter base, service entrance conductors, main breaker, and panel. Exact responsibility can vary by utility and site, so let the utility confirm their side.

Use this split as a practical guide:

Do not remove the meter, cut a seal, open the service side of the panel, or try to tighten meter jaws or service lugs. Those parts can remain energized even when the house appears dead. If the utility says their side is normal, the next step is a licensed electrical diagnosis and, where required, an ESA notification and inspection.

City Power Electrical Services is a Licensed Electrical Contractor, ECRA/ESA #7015314, and provides 24/7 emergency service in Toronto and the GTA for situations like a single-house outage after the utility has been contacted.

The common causes are at the service entrance, meter base, main breaker, or main panel

If the street has power but your house does not, the fault is often at the equipment that brings power from the utility into the home. This is not the same as a tripped branch circuit. It is upstream of the normal room-by-room breakers.

Common causes include:

• Failed main breaker or main disconnect. The handle may look normal, but the internal mechanism or contacts may not be carrying power.
• Loose or burned service connection. A poor connection at the service mast, weatherhead, meter base, or main lugs can fail suddenly under load.
• Damaged overhead service mast. Ice, wind, tree limbs, or a pulled cable can damage the mast or service attachment.
• Underground service lateral fault. Homes with underground supply can lose power from a failed underground cable or connection point.
• Meter base failure. Heat, corrosion, water entry, or worn meter jaws can interrupt supply and may leave visible scorching or melting.
• Utility-side fuse, transformer, or connection serving one property. Sometimes one house can be affected even when the rest of the street is lit.
• Load-related failure. The outage may happen when a large load starts, such as heating equipment, an EV charger, a range, or air conditioning, revealing a weak main connection.

A licensed electrician will not guess at these. The diagnostic process normally starts with visual safety checks, then voltage testing at safe accessible points. If utility isolation is needed, the electrician coordinates with the utility before working on sealed or service-side equipment. If repair work is required on customer-owned service equipment, it must be done under the Ontario Electrical Safety Code process, with ESA notification where required and inspection before reconnection when applicable.

If the outage followed a storm, utility switching, or a surge, also read what to do after a power surge. Surge symptoms can overlap with service equipment failure, but the repair path is different.

Stay out of the panel if there are warning signs

Stay away from electrical equipment if you see, hear, or smell anything abnormal. A completely dark house can still have live parts at the meter, service conductors, or panel line side. The danger is not whether the lights are on; it is whether energized conductors are present where insulation, lugs, or enclosures have failed.

Leave the equipment alone and call for help if you notice any of these:

• Burning smell near the panel, meter, or outside service mast.
• Crackling, popping, or arcing sounds.
• Heat, smoke, soot, or melted plastic at the meter or panel.
• Water entering the panel area or meter base.
• A service mast pulled away from the house.
• A downed or sagging overhead wire.
• Lights that were unusually bright or dim before the outage.
• A main breaker that trips again immediately or will not stay in position.

You can safely unplug sensitive electronics if it is easy to do and there is no sign of heat, water, or arcing. You can also turn off large loads, such as the range or dryer, before power is restored. But do not keep cycling the main breaker. Repeated operation can worsen a failing connection and makes diagnosis harder.

If the home has had grounding or bonding concerns, a single-house outage is a good time to have the service checked as a system, not just restored quickly. Proper grounding does not make a bad service connection safe, but it is part of fault clearing and surge protection. See how to tell if your house is properly grounded for related warning signs.

An electrician’s inspection confirms whether the house can be safely re-energized

A licensed electrician’s job is to find the failed point and confirm the service is safe before normal use returns. For a non-utility cause, a comprehensive GTA electrical safety inspection is typically $250–$400, and emergency repair work is quoted in writing after the cause and scope are known.

For a whole-house outage, the inspection is more focused than a general homebuyer walk-through. It may include:

• Service mast, weatherhead, conduit, and attachment point condition.
• Meter base condition, including signs of heat, corrosion, water entry, or loose mounting.
• Main breaker or main disconnect operation and visible condition.
• Panel bus, neutral bar, grounding and bonding conductors, and service conductor terminations where safely accessible.
• Evidence of overheating from high-load equipment.
• Verification that any repair needing ESA notification is filed and inspected.
• Coordination with the utility for disconnect, reconnect, or meter-related work.

If the cause is a failed main breaker, damaged meter base, service mast issue, or obsolete panel condition, the repair may be more than a reset. If the service equipment is old or undersized, the conversation may also include whether a panel upgrade or service repair is the right long-term fix; the immediate priority is safe restoration, not selling unnecessary work.

For homeowners trying to sort out whether this is a common question or a true emergency, the electrical answers hub can help with smaller symptoms. But when only your house is dark and the neighbours have power, the safest sequence is clear: check the utility, stay away from the meter and service equipment, then bring in a licensed electrician if the utility side is not the cause.
