A dark house in Newmarket can mean three different things. The whole street may be out, and the Town's electricity page puts restoring service after an outage in NT Power's hands. Part of the house may be out, which NT Power's own rules treat as work for an electrical contractor. Or the lights may still be on while a storm has left the service mast leaning away from the wall. Only the last two call for an emergency electrician in Newmarket, so sort out which one you have before you pick up the phone.
KV Bear Electrical moves urgent Newmarket repairs ahead of planned work while its office is open, on weekdays between 7am and 6pm and on Saturdays between 8am and 2pm. Anything burning, smoking or sparking is a 911 call, and a power outage or a line on the ground goes to NT Power at 1-888-735-4801.
What Newmarket Homeowners Should Know
NT Power's Conditions of Service (effective March 14, 2022) ask a customer who loses power to look before calling. If NT Power's main supply appears to have failed, the customer should report it to NT Power at once. If the failure is only partial, the customer should get an electrical contractor to carry out the repairs.
Source: Conditions of Service (effective March 14, 2022), NT Power (ntpower.ca)NT Power's outage FAQ gives two reasons one home can be dark while the house next door has power: the homes may be on separate distribution circuits, even on the same street, or the problem may be specific to that property's electrical system. The FAQ adds that a loss of supply from Hydro One can cause an outage for NT Power customers even when NT Power's own equipment has no fault.

A loud bang during an outage, its FAQ explains, comes from a fuse on the distribution system operating to isolate the power to a problem area.

It also says not to run a generator inside a home or garage, to plug equipment directly into the generator, and not to connect a generator to a home's electrical system.

Once a contractor has completed the repair and notified ESA, an ESA inspector confirms the power can be reconnected and informs the utility.
Source: Checking for Electrical Damage Around Your Home from the Ice Storm, Electrical Safety Authority (esasafe.com)ESA's guideline on residential services damaged during emergencies says that when a rigid steel mast is broken or creased, the condition of the conductors inside cannot be determined, so the utility must isolate and de-energize the service immediately. A mast that is bent but not cracked, where the bend is unlikely to damage the conductors, may be left energized temporarily. The guideline makes the utility responsible for the overhead supply conductors up to the demarcation point, and requires every damaged consumer's service to be reported to ESA so the owner has it repaired.

On new buildings the point of attachment may not be anchored on the fascia board; on existing ones, the fascia and attachment must be supported in a way equivalent to fastening to the building structure.

Power Outage in Newmarket, or a Fault on Your Side of the Meter?
Start at a window. If the street lights and the houses across the road are dark as well, the fault is on NT Power's system or further upstream. NT Power points out that a lost supply from Hydro One can black out its customers even when nothing is wrong with the lines it maintains. Check the outage map, report the outage if your street is missing from it, and leave the panel alone. That kind of outage is not a job for an electrician.
If yours is the only dark house, the cause still may not be yours. NT Power's FAQ notes that homes on one street can be fed by different distribution circuits. Take a flashlight to the panel. If the main breaker is on and nothing looks scorched or wet, report the outage to NT Power before deciding the fault is inside.
Partial power is the clearest sign of a house problem. When some rooms work and others do not, NT Power's Conditions of Service send the customer to an electrical contractor. A blink that lasts a second or two is different, since NT Power classes an interruption of a minute or less as momentary. Lights inside your house that keep dimming or surging while the neighbours' stay steady are worth booking, because ESA's homeowner handbook links that pattern to loose connections in a lighting circuit, a fixture or the electrical service.
Storm Damage in Newmarket: Masts, Fascia Attachments and Fallen Limbs
The Town estimates that the July 3, 2026 storm damaged more than 200 trees on its property around Yonge Street and Mulock Drive, and storms like that are when service wires get hit. A falling limb can pull the point of attachment off the house or kink the mast that carries the wires down to the meter. Keep your distance and call NT Power's emergency line about any branch resting on a line. Whoever ends up clearing the tree, the wires have to be made safe before anyone starts cutting.
When the wires are clear, look the house over from the yard. ESA's advice after the 2025 ice storm holds for any storm: even if the power never went out, a mast can be pulled away from the wall or the wires can sag toward the ground. That equipment is yours to fix. NT Power's Conditions of Service leave the upkeep of the customer's service equipment to the customer, and ESA's damage guideline makes the utility responsible for the overhead supply conductors up to the demarcation point.
How the mast is damaged decides what happens next. ESA's guideline tells utility crews to isolate and de-energize a service right away when a rigid steel mast is broken or creased, because sharp edges inside may have damaged the conductors. A mast that is bent but not cracked, with a bend unlikely to harm the conductors, may stay live for a while. Either way, the damage is reported to ESA so the owner arranges the repair.
Some houses take their wires on the fascia board instead of a mast. ESA has seen those attachments fail where the board was too thin or poorly fastened, and new buildings may not use the fascia at all. On an existing house, the repair has to leave the board and attachment as solid as a fastening to the building structure, so expect the board to be checked before the wires go back up. When the Licensed Electrical Contractor has finished and ESA has inspected, ESA tells NT Power the house can be reconnected.
Urgent Electrician in Newmarket: Staying Safe Until the Repair
An electrical emergency in Newmarket usually has a waiting stretch between making things safe and getting them fixed. Central York Fire Services publishes blackout advice that fits it. Light the house with flashlights, never candles. Switch off whatever was running when the power failed, and leave a single lamp on so you notice when the supply returns. NT Power adds that appliances and electronics should be unplugged so a power surge cannot damage them.
Portable generators come with firm limits. CYFS says to run one outside, never in the house or garage, to plug each appliance directly into it, and never to connect it to the home's electrical system.
If one circuit is the trouble, leave its breaker off instead of resetting it over and over. Write down which breakers have moved, which rooms are out and whether anything outside looks damaged, and photograph the mast or meter base from a safe distance. Those notes are what an electrician needs to book emergency electrical service in Newmarket as an urgent job when the office opens.
Emergency Electrician in Newmarket: Common Questions
Half the outlets in my Newmarket house stopped working. Is that NT Power's problem?
Usually not. NT Power's Conditions of Service separate the two cases: a failure of NT Power's main supply gets reported to the utility, while a partial failure is for an electrical contractor to repair. Check the panel for a tripped breaker. If it trips again as soon as it is reset, or several circuits are out together, leave them off and book the repair.
What does a loud bang right before a Newmarket outage mean?
NT Power's outage FAQ says it comes from a fuse on the distribution system operating to isolate the power to a problem area. In other words, the utility's own protection operated, which points to a problem on NT Power's system rather than in your panel. Report the outage on 1-888-735-4801 or through the webchat on NT Power's outage map, and keep away from any wire that has come down.
Can I cut a tree limb that is lying on the wires to my Newmarket house?
No. NT Power asks people to contact its emergency line as soon as possible about branches on power lines, so make that call first and keep everyone back. Leave the cutting until NT Power has dealt with the wires. If the limb bent the mast or tore the attachment off the wall, that repair goes to a Licensed Electrical Contractor.
Does the sale of NT Power to Alectra change who I call during a Newmarket outage?
Not yet. The Town's March 2, 2026 notice says NT Power will keep operating as an independent company under its existing board of directors throughout the Ontario Energy Board process. The Town's electricity page still sends outage reports to NT Power at 1-888-735-4801, so use that number until NT Power or the Town announces a change.
How do I book an urgent electrical repair at a Newmarket home?
Phone during business hours, Monday to Friday 7am to 6pm or Saturday 8am to 2pm, and say the problem is urgent. Have the details ready: which circuits are out, whether the mast or meter base looks damaged, and whether NT Power already knows about an outage. The repair is quoted before any work begins, and it is filed with ESA when the rules call for it. Call 905-999-5048 or request a quote.
