Electrical Panel Upgrade in Toronto: 100A to 200A Service Upgrades, Panel Replacement & Fuse Box Replacement
Toronto Electrical Panel Upgrade is an ECRA/ESA licensed electrical contractor specialising exclusively in electrical panel upgrade projects, service upgrades, fuse box replacement, and breaker panel installations across the Greater Toronto Area. We handle 60A to 100A upgrades, 100A to 200A service upgrades, 200A to 400A commercial upgrades, subpanel installations, and full service entrance replacements, with ESA permit filing and Toronto Hydro disconnect coordination on every job.
A 100A to 200A electric panel upgrade in Toronto runs $2,500 to $8,000 CAD depending on whether the service is overhead or underground and which load centre you choose from Siemens, Square D / Schneider Electric or Eaton. A 60A to 100A upgrade runs $1,500 to $4,000 CAD and a fuse box to breaker conversion $1,800 to $5,000 CAD. Every quote is written and itemised, with the ESA permit fee and the utility coordination fee on separate lines.
Most calls start with a trigger: a Level 2 EV charger, a cold-climate heat pump, an induction range, a hot tub, a basement-suite subpanel, a renovation that puts the panel in front of an ESA inspector, an insurance renewal condition, or a 60A fuse panel flagged during a home inspection. We run the OESC Section 8 demand calculation first and tell you whether the existing service carries the load or a service upgrade is the honest answer.
We work Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Ajax, Pickering, Whitby and Oshawa, with Hydro One coordination for outer-GTA properties inside our 50km radius.

We serve Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan and Markham on Alectra Utilities, and outer-GTA industrial parks on Hydro One inside our 50km industrial radius.
View serviceWhen Do You Need an Electrical Panel Upgrade in Toronto?
Eight triggers account for almost every panel upgrade we quote. If one of these describes your property, the load calculation will tell you how far the existing service can stretch.
Home insurance refusal or a renewal notice
Toronto underwriters decline or surcharge policies on homes still running an obsolete 60A service or a fuse block. The ESA Certificate of Inspection is what closes the file.
Level 2 EV charger installation at 40A or 50A
An EV charger is a continuous load. Added to laundry, HVAC and refrigeration on an aged 100A panel, the OESC Section 8 calculation runs out of room fast.
Heat pump or central air conversion
Moving off gas heating to a cold-climate heat pump needs dedicated high-amperage breakers and headroom the original panel was never sized for.
Legal basement suite or accessory dwelling unit
City of Toronto secondary-suite permits require a documented load calculation, a dedicated subpanel and a separate disconnect for the suite.
Screw-in glass fuses or cartridge fuse blocks
Fuse blocks cannot provide the arc-fault and ground-fault protection the Ontario Electrical Safety Code now expects on modern branch circuits.
Flickering lights when appliances start
That flicker is voltage drop under load. It points at bus-bar saturation or loose terminations at the main breaker, both end-of-life signals.
Doubled-up breakers with no knockouts left
When every position is tandemmed and the enclosure has no knockouts left, adding a circuit safely means a new load centre, not more stacking.
Corroded service mast or meter base
A weathered mast and weatherhead lets water track into the panel interior. The service entrance conductors and meter base get replaced with the panel.

Panel Replaced. Permit Pulled. Inspection Passed.
Six reasons Toronto homeowners and property managers hand panel work to a specialist instead of a general contractor.
-
20+ Years of Electrical Panel Upgrade Experience
Over two decades of ECRA/ESA-licensed panel replacement, service entrance upgrades, fuse box conversions and utility coordination across Toronto and the GTA. Every crew member is a panel-upgrade specialist first.
-
Panel-only specialists
We do not chase general electrical work. Panel upgrades, fuse box replacement, subpanels and service entrance work are the whole business, which is why the utility and ESA steps run without surprises.
-
ESA permit filed on every job
Every project gets a Notification of Work and a final inspection. No exceptions, no "we can skip the permit" conversations, and the fee is visible on the quote.
-
Utility coordination handled directly
Toronto Hydro inside the city, Hydro One for outer-GTA addresses, and Alectra, Elexicon, Oakville Hydro, Burlington Hydro or Oshawa Power in the region. You never have to book a meter pull yourself.
-
Written itemised quotes
Labour, materials, the ESA permit fee and the utility coordination fee are broken out separately, so you can see exactly what changes if the scope changes.
-
Insurance-required upgrades documented
When an insurer flags a 60A service, a fuse panel, a Federal Pacific Stab-Lok or aluminum wiring, we complete the work and hand over the documentation underwriting asks for.
-
Panel brand options explained
Siemens, Square D / Schneider Electric and Eaton load centres each have trade-offs in breaker availability and cost. We explain them and let you choose. Warranty terms are the manufacturer’s.
How We Are Different
Most electrical contractors treat a panel upgrade as one job type among dozens. That works until the utility disconnect slips, the ESA inspector flags a grounding electrode conductor, or the meter base turns out to need replacing on a service the quote assumed was fine. Those are the moments where a general crew loses a day and a specialist does not, because the material is already on the truck and the utility contact is already made.
Our whole workflow is built around the dependency chain: load calculation, ESA Notification of Work, utility service layout approval, disconnect booking, install, inspection, reconnect. We quote against that chain, not against an optimistic hour count, which is why the invoice matches the quote and the power comes back on the day we said it would.
It also means we will tell you when you do not need a service upgrade. If the demand calculation shows headroom on your existing 100A or 200A service, a subpanel or an EVEMS load-management device solves the problem for a fraction of the cost, and that is what we will quote.
Layout Approved. Meter Pulled. Power Back Same Day.
The Toronto Hydro coordination process, step by step. Hydro One, Alectra Utilities, Elexicon Energy, Oakville Hydro, Burlington Hydro and Oshawa Power follow the same sequence with their own booking windows.
- 01
Service layout approval
We submit the new service layout, conductor sizing and meter base position so the utility can confirm the point of attachment before any material is ordered.
- 02
Disconnect scheduling
Once the ESA Notification of Work is filed, we book the disconnect slot. Morning slots let us finish and re-energize inside the same working day.
- 03
Meter pull and service change
The utility pulls the meter and drops the service. We replace the meter base, service entrance conductors, mast or lateral, and the load centre.
- 04
ESA inspection
The ESA inspector attends, reviews bonding, grounding, terminations and labelling, and signs off the Certificate of Inspection.
- 05
Energization and handoff
The utility reconnects and sets the meter. You get the certificate, the panel schedule and the itemised invoice matching the original quote.
The ESA Permit Process in Ontario
Every panel upgrade in Ontario is notifiable work. That means a licensed electrical contractor files a Notification of Work with the Electrical Safety Authority before the job starts, and an ESA inspector reviews the finished installation before the utility re-energizes it. There is no compliant path that skips either step.
-
Notification of Work
Filed under our ECRA/ESA contractor licence with the scope, service size and property address. The fee appears as its own line on your quote.
-
Inspection booking
Scheduled to land on install day so the inspection, sign-off and utility reconnect can happen in sequence without an extra outage.
-
Certificate of Inspection
Issued once the work passes. This is the document insurers, lawyers and buyers accept as proof the panel meets the Ontario Electrical Safety Code.
-
Commercial plan review
Commercial and industrial projects add an ESA plan review before install, covering single-line diagrams, load studies and short-circuit current ratings.
Our 5-Step Job Process

ESA permit application
The Notification of Work is filed in your name with the scope we quoted. The permit fee sits on its own line in the quote.
- 03
Utility booking
Toronto Hydro, Alectra, Elexicon, Oakville Hydro, Burlington Hydro, Oshawa Power or Hydro One, whichever holds your service.
- 04
Install day
Panel, meter base and service entrance replaced, circuits transferred and labelled, grounding electrode conductor verified.
- 05
ESA inspection and reconnect
Inspection passes, the utility reconnects, and the Certificate of Inspection goes to you and your insurer if one is waiting on it.

What Toronto Customers Say
Panel upgrades, fuse box conversions, Stab-Lok replacements and EV circuits across city neighbourhoods.
Our 100A panel could not carry the heat pump and induction range, so the crew ran a 100A to 200A upgrade and coordinated the Toronto Hydro disconnect for the morning. Full ESA approval the same afternoon.
Insurance flagged the screw-in fuse box on our 1920s semi and gave us a deadline. The crew replaced it with a 42-circuit breaker panel and filed the ESA certificate our insurer accepted.
Home inspection found a Federal Pacific Stab-Lok panel before closing. They identified it, replaced the panel to OESC code, and had the Certificate of Inspection ready in time for possession.
Added a Level 2 EV charger in the garage. The crew ran a dedicated 50A circuit off a new 200A service and coordinated the meter pull with Toronto Hydro cleanly.
Building a legal basement suite meant a separate 100A subpanel and disconnect. The load calculation and ESA sign-off were handled on time so our secondary-suite permit stayed on track.

Electrical Panel Upgrade FAQs
Cost, timelines, permits, utility disconnects and insurance requirements, answered for Toronto and the GTA.
How much does an electrical panel upgrade cost in Toronto?
A 100A to 200A upgrade runs $2,500 to $8,000 CAD depending on overhead versus underground service and panel choice. A 60A to 100A upgrade is $1,500 to $4,000 CAD, and a fuse box to breaker conversion is $1,800 to $5,000 CAD. Every quote is written and itemised with the ESA permit fee and Toronto Hydro coordination fee broken out separately.
How long does an electrical panel upgrade take in Toronto?
A 100A to 200A upgrade takes 1 to 2 days, with the Toronto Hydro disconnect and reconnect booked in advance and completed the same day. A fuse box to breaker conversion is typically 1 day.
Do I need a permit to upgrade my electrical panel in Toronto?
Yes. Every panel upgrade requires an ESA Notification of Work (permit) and a final ESA inspection. We file the permit and handle the inspection on every job, and the permit fee is included in the written quote.
What is the difference between a 100A and 200A electrical panel?
A 100A service carries a basic modern home, while a 200A service adds headroom for EV charging, a heat pump, induction cooking and a basement suite at the same time. A 200A panel commonly holds 42 circuits versus far fewer on an older 100A panel.
Why would I need to upgrade my electrical panel?
Common triggers are an insurance requirement, frequent breaker trips on modern loads, a 60A or fuse panel, a flagged Federal Pacific Stab-Lok or aluminum wiring, and no space for an EV charger, hot tub, heat pump or basement-suite subpanel.
Does Toronto Hydro need to disconnect power for a panel upgrade?
Yes. Toronto Hydro disconnects the service so the meter base and panel can be replaced safely, then reconnects after the ESA inspection passes. We coordinate the disconnect and reconnect directly, usually the same day, and use Hydro One for outer-GTA properties.
What does ESA certification mean for panel upgrades in Ontario?
The ESA Certificate of Inspection confirms an ESA inspector reviewed the work and it meets the Ontario Electrical Safety Code. It is the document insurers and lawyers accept as proof the panel work is code-compliant.
Can I stay home during an electrical panel upgrade?
Yes, though power is off for part of the day during the Toronto Hydro disconnect. Most 100A to 200A upgrades cut power in the morning and re-energize the same afternoon after the ESA inspection.
Will my homeowner's insurance require a panel upgrade?
Many Toronto insurers require replacing a 60A service, a fuse box, a Federal Pacific Stab-Lok panel or aluminum wiring before they renew or issue a policy. We complete the flagged upgrade and provide the ESA certificate underwriting accepts.
What are the signs my electrical panel needs replacing?
Frequent breaker trips, a warm panel, flickering lights when appliances start, no free breaker slots, double-tapped breakers, screw-in fuses, and a corroded service mast or meter base all point to a panel at end of life.
What triggers the need for a 200A upgrade in Toronto?
EV charging, a heat pump, an induction range, a hot tub and a basement-suite subpanel each add significant load. When an OESC Section 8 calculation exceeds a 100A service, a 200A upgrade is the fix.
How much does a fuse box replacement cost in Toronto?
A fuse box to breaker panel conversion runs $1,800 to $5,000 CAD depending on the panel size and service condition, with the ESA permit fee included in the written quote.
Do you handle commercial electrical panel upgrades in Toronto?
Yes. We upgrade commercial and light-industrial service from 200A to 400A, including CT cabinets, single- and three-phase supply, and the commercial ESA plan review, for restaurants, offices, retail units, warehouses and manufacturing facilities.
What panel brands do you install in Toronto?
We install Siemens, Square D / Schneider Electric and Eaton load centres, and explain the pros and cons of each so you can pick the panel that fits your home and budget. Any warranty terms are those of the panel manufacturer.
