# 100A to 200A Upgrade Toronto | Toronto Electrical Panel Upgrade URL: https://electricalpanelupgradetoronto.ca/100a-to-200a-service-upgrades/ ![Crew installing a 200A main breaker and 42-circuit load centre in a Toronto basement](/images/misc/two-electricians-in-plain-navy-workwear-seen-from-.webp) Most Requested # 100A to 200A Service Upgrades in Toronto and the GTA for EV, Heat Pump & Suite Loads A 100A to 200A service upgrade in Toronto is Toronto Electrical Panel Upgrade [/ →](/) 's most-requested job. Upgrade from an undersized 100A service to a full 200A, 42-circuit panel with 2/0 AWG copper or 4/0 AWG aluminum service entrance conductors sized per OESC Section 8, a new meter base, weatherhead and mast where required, whole-home surge protector, copper grounding electrode conductor, and ESA Certificate of Acceptance. Toronto Hydro disconnect and reconnect coordinated end-to-end so you get one point of contact for permit, materials, and utility scheduling. A 100A to 200A upgrade in Toronto costs $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 or Eaton, with the ESA permit fee and utility coordination fee itemised on the written quote. Most calls start with a trigger: a Level 2 EV charger install, a cold-climate heat pump, an induction range, a hot tub or sauna, a basement-suite subpanel, a major renovation that puts the panel in front of an ESA inspector, or a 60A fuse panel flagged during a home inspection. We serve Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan and Markham on Alectra Utilities, Oakville on Oakville Hydro, Burlington on Burlington Hydro, and Ajax, Pickering, Whitby on Elexicon Energy inside our 50km radius. - ECRA/ESA Licensed - ESA Permit Included - Utility Coordination Handled - Written Itemised Quote Get a Free On-Site Estimate [/free-estimate/ →](/free-estimate/) +1-647-577-6113 [tel:+16475776113 →](tel:+16475776113) Written itemised quote $ 2,500 to $8,000 CAD - ESA permit filed and inspection booked - Utility disconnect and reconnect coordinated - Same-Week Scheduling View Pricing Detail [#pricing →](#pricing) - ECRA/ESA Licensed - ESA Permit Included on Every Job - Same-Week Scheduling - WSIB Certified - Free Written Itemised Quote ## What Is a 100A to 200A Service Upgrade? A 100A to 200A service upgrade replaces the main breaker, the load centre, the meter base and the service entrance conductors so the property can draw twice the continuous current it could before. It is not a panel swap. The whole service from the Toronto Hydro service drop or underground lateral, through the weatherhead and meter base, down to the main breaker, is rebuilt to carry 200A. For a Toronto home that means moving from a panel with every position filled to a 42-circuit load centre on a copper bus bar, with real spare capacity left after the existing circuits transfer across. The 2/0 AWG copper service entrance conductors and the new meter base are sized to the upgraded service, and the grounding electrode conductor is verified rather than assumed. The trigger is almost always electrification. A Level 2 EV charger draws 40A or 50A continuous, and the Ontario Electrical Safety Code treats it as a continuous load at 80%, so it eats capacity fast. Add a cold-climate heat pump, an induction range and a basement-suite subpanel, and an OESC Section 8 demand calculation on a 100A service runs out of room before the renovation is finished. Because the meter has to come off, this is coordinated work rather than a same-hour job. We file the ESA Notification of Work, submit the service layout to Toronto Hydro, book the disconnect, complete the install, pass the inspection and hand back the Certificate of Inspection. For the rest of the residential range, see residential electrical panel upgrades [/residential-electrical-panel-upgrades/ →](/residential-electrical-panel-upgrades/) . ### Types of 100A to 200A Upgrade - **Overhead mast, panel in place.** The service drop lands on a new mast and weatherhead, the meter base is replaced, and the new 200A load centre goes in the same position as the old one. The cleanest version of this job. - **Overhead with panel relocation.** The existing panel sits in a closet or under a stair with no working-space clearance, so the new load centre moves to a compliant wall and the feeder is rerouted. - **Underground lateral.** Common on rebuilt streets in Mimico, Guildwood and parts of North York. The lateral, meter base and load centre are all replaced, and any trenching or conduit work is priced separately in the quote. - **200A service with a suite subpanel.** The service upgrade and a 60A or 100A subpanel on a four-wire feeder are installed together, which is cheaper than doing them as two projects. ## When Do You Need to Go From 100A to 200A? - **Level 2 EV charging.** A 40A or 50A continuous load on top of laundry, HVAC and refrigeration is where most 100A services fail the calculation. Where the panel is otherwise healthy, an EV charger electrical upgrade [/ev-charger-electrical-upgrades/ →](/ev-charger-electrical-upgrades/) with an EVEMS device is the alternative worth pricing. - **Heat pump conversion.** Moving off gas heating adds a large dedicated load plus backup heat, and the calculation has to hold on the coldest design day, not the average one. - **Induction range plus electric water heating.** Two large resistive loads that arrive together in most kitchen renovations. - **Basement suite or accessory dwelling unit.** The City of Toronto expects a documented load calculation, a dedicated subpanel and a separate disconnect. See basement suite electrical upgrades [/basement-suite-electrical-upgrades/ →](/basement-suite-electrical-upgrades/) . - **No spare breaker positions.** Tandems in every slot and no knockouts left means the enclosure, not the breaker count, is the limit. - **Failing panel hardware.** Bus-bar corrosion, double-tapped terminals or a warm enclosure means the panel needs replacing anyway, so the incremental cost of upgrading the service at the same time is small. That path is covered under electrical panel replacement [/electrical-panel-replacement/ →](/electrical-panel-replacement/) . ## What Drives the Cost Between $2,500 and $8,000 Four variables move a quote inside the band. **Service type** is the biggest: an underground lateral with trenching costs materially more than a mast and weatherhead replacement. **Conductor routing** is second, because the distance from the meter base to the panel position sets the length of 2/0 AWG copper and any conduit needed. **Panel choice** between Siemens, Square D / Schneider Electric and Eaton shifts material cost. **Scope added by the calculation** is the fourth: a grounding electrode conductor that has to be run to the water service, a panel relocation for working-space clearance, or a subpanel the suite plan requires. What does not move is the ESA permit fee, which is included, and the Toronto Hydro coordination fee, which is itemised on its own line so you can see it. Where we find something after the service is opened that changes the scope, work stops and you get a revised written quote before we continue. ## What to Expect on Install Day Toronto Hydro arrives in the morning to pull the meter and drop the service. From that point the property is without power. We remove the old load centre, replace the mast or lateral and the meter base, pull the new service entrance conductors, and mount the 200A load centre. Existing circuits move across onto correctly sized breakers, arc-fault and ground-fault protection goes on the circuits that require it, terminations are torqued to specification, and the panel schedule is written and fixed inside the door. The ESA inspector attends to review bonding, grounding, terminations and labelling. Once the Certificate of Inspection is signed, Toronto Hydro reconnects and sets the meter. On a standard overhead job, power is back the same afternoon. Before we leave, you get the certificate, the panel schedule and the itemised invoice that matches the original quote. ## What Triggers a 200A Upgrade in Toronto: EV Chargers, Heat Pumps, Suites, and Inspector Flags Most Toronto 200A upgrades are triggered by one of six real load additions or one of four inspector-flagged discoveries. The trigger determines the timeline, the utility coordination window, and whether an ESA amendment is required. ### The six most common load triggers - **Level 2 EV charger install:** a 40-60A dedicated circuit for a Tesla Wall Connector, ChargePoint Home Flex, or Grizzl-E Classic pushes a 100A service past its 80% continuous load ceiling. - **Cold-climate heat pump:** a Mitsubishi Zuba or Daikin Aurora ducted heat pump on a 240V split-phase circuit adds 30-50A of continuous load in heating mode. - **Induction range and induction cooktop combination:** a full-kitchen induction retrofit adds a 40-50A circuit plus a 20A dedicated countertop circuit. - **Hot tub, sauna, or pool heater:** a 40-60A GFCI-protected circuit for a Softub, Arctic Spa, or Sundance Optima. - **Basement suite subpanel with second-suite metering:** an OESC Section 26 second-suite install typically pulls a 60-100A subpanel off the main service. - **Major renovation on the ESA permit path:** any addition, second-suite, or garage-loft renovation puts the panel in front of an ESA inspector. ### The four inspector-flagged discoveries - **60A fuse panel flagged during a home inspection:** the buyer’s insurer refuses to bind coverage until the panel is upgraded to a 100A or 200A breaker service. - **Federal Pacific Stab-Lok or Federal Pioneer panel:** insurers and ESA both push for immediate replacement due to documented breaker-trip failure rates. - **Aluminum branch-circuit wiring feeding a modernised load:** insurers require an ESA-certified pigtail retrofit or full rewire before increasing service size. - **A Toronto Hydro service drop that predates 1990:** older drops on 100A meter bases with corroded neutrals get replaced during the upgrade, not before. ## Signs Your 100A Panel Is Overloaded: Warm Bus Bars, Nuisance Trips, Full Positions, No Spare A 100A panel usually gives four or five obvious signals before it stops being safe. Homeowners often notice one signal at a time and only connect them at the load calculation stage. ### Physical warning signs at the panel - **Warm enclosure or warm breakers:** heat you can feel on the panel cover means terminations are loose, breakers are undersized for the actual continuous load, or the bus bar is starting to pit. - **Discoloured or browned breaker faces:** yellowing on a Siemens QP, Square D HOM or Eaton BR breaker indicates repeated overheating on that circuit. - **A hum, buzz or occasional pop from inside the enclosure:** normal AC hum is quiet. A loud or intermittent buzz signals a loose neutral or a failing breaker. - **Corrosion, rust or moisture inside the cabinet:** any water ingress on a bus bar or a grounding electrode conductor lug is an immediate ESA concern. ### Circuit-level and load symptoms - **Nuisance trips on the dryer, kitchen, or AC circuit:** especially when the dryer and range run at the same time, or the AC compressor starts. - **Lights dimming when a large motor starts:** the pump, the compressor or the microwave pulling voltage down means the service is at its ceiling. - **Every breaker position full, and tandem breakers doubled up:** if the panel has no knockouts left and tandems are in every 15A and 20A slot, the enclosure is the limit rather than the amperage. - **A 100A service feeding gas heat, gas water heat, and no EV:** if the calculation is already close to 100A on the current loads, the next appliance addition triggers the upgrade. ## Overhead Mast vs Underground Service for a 200A Upgrade: Cost, Timeline, and Toronto Hydro Coordination Toronto has both service styles, and which one you have decides how the 200A upgrade is priced and scheduled. The choice is set by the original build, not by preference. ### Overhead mast service upgrades - **Applies to most pre-1990 Toronto Hydro service drops:** a service cable from the pole to a mast on the roof, into the meter base, and down to the panel. - **Materials replaced on a 200A overhead job:** a new 2 or 3 inch rigid galvanised mast, a 200A weatherhead, 2/0 AWG copper or 4/0 AWG aluminum service entrance conductors, a 200A meter base. - **Toronto Hydro coordination window:** the disconnect and reconnect happen on the same day, usually within a 4-6 hour outage. The service drop reattachment is handled by Toronto Hydro on the same visit. - **Typical price band:** $2,500 to $6,000 CAD depending on mast height and conductor length. ### Underground lateral service upgrades - **Applies to newer subdivisions on Alectra Utilities or Elexicon Energy:** a buried service lateral running from a transformer or pedestal to a below-grade meter base. - **What gets replaced on a 200A underground job:** the meter base, service entrance conductors from the meter to the panel, and sometimes the lateral itself if it is undersized or aluminum-degraded. - **Trenching, conduit and civil work:** if the lateral needs replacing, a trench from the transformer pedestal to the house is required, plus a locate through Ontario One Call. - **Typical price band:** $5,000 to $8,000 CAD once civil work is included, with a longer timeline due to utility scheduling and locate lead time. ### When the service type changes - **Overhead to underground conversion:** possible but rare on a Toronto Hydro 200A residential upgrade. It requires a coordinated project with the utility and is priced as a full service change, not a panel upgrade. ## How Much Does 100A to 200A Upgrades Cost in Toronto? A 100A to 200A upgrade runs $2,500 to $8,000 CAD. The ESA permit fee is included and the Toronto Hydro coordination fee is itemised separately on every written quote. Typical range $ 2,500 to $8,000 per upgrade (CAD) - ESA permit fee included - Final ESA inspection included - Utility coordination itemised, never hidden Get an Itemised Quote [/free-estimate/ →](/free-estimate/) ### What Moves the Price #### Overhead mast or underground lateral An underground service entrance needs trenching and civil work, so it sits higher in the range than a mast and weatherhead replacement. #### Panel brand and circuit count Siemens, Square D / Schneider Electric and Eaton load centres price differently, and a 42-circuit panel costs more than a small enclosure. #### Service entrance length and routing Conductor length from the meter base to the panel, plus any wall penetration or conduit work, changes the material and labour line. #### Scope flagged by the load calculation An OESC Section 8 result can add a subpanel, a grounding electrode conductor or a meter base that was not in the original plan. | Scope | Low | High | | --- | --- | --- | | Overhead mast, panel swap in place | $ 2,500 | $ 4,500 | | Overhead mast with new meter base and conductors | $ 3,500 | $ 6,000 | | Underground lateral with civil work | $ 5,000 | $ 8,000 | ## Why Choose Us for 100A to 200A Upgrades? ECRA/ESA licensed, permit filed, utility coordinated, quote itemised. - ### 20+ Years of 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. Panel work is the whole business, not a side service. - ### Same-day energization Because the disconnect is booked before material is ordered, power goes off in the morning and comes back the same afternoon on most 100A to 200A jobs. - ### 42 circuits, not 24 We size the load centre with real spare capacity, so the next charger, heat pump or suite circuit does not force a second panel project. - ### Section 8 calculation first The demand calculation decides the answer, not a guess. If 100A still has headroom, we will tell you and quote the cheaper fix instead. - ### One crew for the whole chain Permit, utility booking, install, inspection and reconnect are all handled by the same two-person crew. Nothing gets handed off mid-project. ## How Does 100A to 200A Upgrades Work? The sequence every job follows, from the first load calculation to the utility reconnect. 1. 01 ### Load calculation An OESC Section 8 demand calculation covering the existing house plus the EV charger, heat pump, induction range or suite you are adding. 2. 02 ### Permit and layout ESA Notification of Work filed, and the new service layout and meter base position submitted to Toronto Hydro for approval. 3. 03 ### Disconnect and service change Toronto Hydro pulls the meter in the morning. We replace the mast or lateral, meter base, 2/0 AWG conductors and load centre. 4. 04 ### Circuit transfer and labelling Existing circuits move to the new panel on correctly sized breakers, terminations torqued to spec, panel schedule written and fixed inside the door. 5. 05 ### Inspection and reconnect ESA inspection passes, Toronto Hydro reconnects and sets the meter, and the Certificate of Inspection is handed over with the invoice. ## How Toronto Electrical Panel Upgrade Compares | Feature | Typical provider | Toronto Electrical Panel Upgrade | | --- | --- | --- | | ESA permit and final inspection | Quoted as an extra | Included on every job | | Utility disconnect coordination | Homeowner arranges it | Booked and coordinated by us | | Quote format | One lump sum | Itemised: labour, materials, permit, coordination | | Panel circuit count | Smallest enclosure that fits | 42-circuit panel with spare capacity | | Load calculation | Rule of thumb | OESC Section 8 demand calculation | ## Try Our Free Electrical Load Calculator Check if your current panel can carry 100a to 200a upgrades before you book an estimate.

Stefan H.Trinity-Bellwoods ## 100A to 200A Upgrades FAQs ### How much does a 100A to 200A service upgrade cost in Toronto? A 100A to 200A upgrade runs $2,500 to $8,000 CAD. A straightforward overhead mast job with the panel in the same position sits at the lower end. A new meter base, longer service entrance conductors, a panel relocation, or an underground lateral needing trenching pushes toward the upper end. The ESA permit fee is included and the Toronto Hydro coordination fee is a separate line on the quote, so you can see what each part costs. ### How long does a 100A to 200A upgrade take? One to two days on site. The Toronto Hydro disconnect and reconnect happens on the same day, booked in advance, which is what keeps the outage to part of one working day rather than spread across a week. Power typically goes off mid-morning and comes back the same afternoon once the ESA inspection passes. Jobs that also need a mast replacement, a panel relocation or trenching for an underground lateral run into a second day. ### Do I need 200A, or is 100A still enough? The OESC Section 8 demand calculation answers this, not a rule of thumb. A basic modern home with gas heating, gas water heating and a gas range can run comfortably on 100A. Add a Level 2 EV charger at 40A or 50A continuous, a cold-climate heat pump, an induction range, electric water heating or a basement-suite subpanel, and the calculated demand normally exceeds what a 100A service can supply. We run the calculation at the free on-site estimate and show you the number. ### Will Toronto Hydro need to cut my power? Yes. The meter has to be pulled and the service de-energized before the meter base, service entrance conductors and load centre can be replaced safely. We book that disconnect window with Toronto Hydro as soon as the ESA Notification of Work is filed, and request a morning slot so the reconnect lands the same afternoon. ### Can I stay home during the upgrade? Yes. Most people do. Plan around several hours without power: charge devices, keep the fridge and freezer closed, and be aware that anything on a sump pump or medical equipment needs a backup plan for the day. We tell you the expected off and on times when the disconnect window is confirmed. ### What is included in a 42-circuit panel? A 42-circuit 200A load centre gives 42 usable breaker positions on a copper bus bar, which leaves real spare capacity after the existing circuits transfer over. That matters because the next project, a charger, a hot tub, a heat pump or a suite subpanel, then only needs a breaker and a circuit rather than another panel replacement. ### Which panel brand should I choose? We install Siemens, Square D / Schneider Electric and Eaton load centres. Siemens enclosures are deeper, which makes conductor routing tidier on a full panel. Square D QO has the widest arc-fault and ground-fault breaker range. Eaton BR prices competitively and is well stocked through Ontario distributors. Any warranty on the panel or breakers is the manufacturer's, and we explain the trade-offs rather than pushing one brand. ### Does the upgrade include the meter base and mast? Where the service size changes from 100A to 200A, yes, the meter base and service entrance conductors are almost always replaced because the existing ones are rated for the old service. A corroded mast and weatherhead is replaced at the same time. This is why the quote separates the service entrance work from the panel itself. ### Will my insurer want documentation afterwards? If the upgrade was triggered by an insurance condition, yes. The ESA Certificate of Inspection is the document underwriters accept as proof the work meets the Ontario Electrical Safety Code. We hand it to you when the inspection passes, and you can forward it straight to your broker. ### Can the panel move to a different wall? Yes, and sometimes it has to. The Ontario Electrical Safety Code requires defined working space in front of and around a panel, and closets and bathrooms are not acceptable locations. If the existing position fails that test, we price the relocation with the upgrade so the ESA inspection passes the first time. ### Still have a question? Ask the crew directly.

Toronto Electrical Panel Upgrade diagnoses the failing panel (bus bar corrosion, double-tapped terminals, cracked plastic breaker housings, main service disconnect failure, breaker tripping under normal load), coordinates the Toronto Hydro service disconnect and reconnect, files the ESA permit, transfers every circuit to the new panel with fresh labelling, and delivers same-day energization. An electrical panel replacement in Toronto costs $2,000 to $5,500 CAD depending on load centre brand, circuit count (24 vs 42 circuits), and whether the meter base and service entrance conductors are reused or replaced, with the ESA permit fee itemised. Most calls start with a trigger: a burning smell or heat at the panel, a failed home inspection identifying a Federal Pacific Stab-Lok or Zinsco panel, a real-estate closing condition, an insurance renewal flag, breaker trips under normal appliance load, or arc-fault damage. We serve Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan and Markham on Alectra Utilities, Oakville on Oakville Hydro, and Ajax, Pickering, Whitby on Elexicon Energy inside our 50km radius.

Toronto Electrical Panel Upgrade files the ESA permit, coordinates Toronto Hydro service work when required, and delivers the ESA Certificate of Acceptance for your insurer and warranty registration. An EV charger electrical upgrade in Toronto costs $500 to $1,800 CAD for a straight 240V circuit on adequate existing service, $1,800 to $3,500 for an EVEMS or DCC-9 install on a full panel, or $2,500 to $8,000 for a full 100A to 200A service upgrade when required. Most calls start with a trigger: a new Tesla, Ford Lightning, Rivian, Hyundai Ioniq, or Kia EV9 delivery date, a heat pump added to a full panel, an existing 100A service that cannot pass the OESC Section 8 continuous load check, or an insurance requirement for hardwired charging. We serve Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan and Markham on Alectra Utilities, Oakville on Oakville Hydro, and Ajax, Pickering, Whitby on Elexicon Energy inside our 50km radius.

Toronto Electrical Panel Upgrade handles the Toronto Hydro service disconnect and reconnect coordination, files the ESA permit, and delivers same-day energization on most residential jobs. A 60A to 100A service upgrade in Toronto costs $2,000 to $4,500 CAD depending on overhead vs underground service entrance, whether the mast and meter base need replacement, and which load centre you choose from Siemens, Square D or Eaton, with the ESA permit fee itemised. Most calls start with a trigger: a home insurance non-renewal notice, a real-estate closing condition on a Cabbagetown or Riverdale character home, an original knob-and-tube era 60A service flagged during home inspection, or an Edison-base fuse panel that cannot support modern loads. We serve Toronto, Etobicoke, Scarborough, North York, York and East York on Toronto Hydro, plus Mississauga, Brampton, Vaughan and Markham on Alectra Utilities, Oakville on Oakville Hydro, and Ajax, Pickering, Whitby on Elexicon Energy inside our 50km radius.
