When a panel swap alone will not do it, a full service upgrade replaces the service mast, meter base, and coordinates the utility disconnect and reconnect with Toronto Hydro. Our crew handles the point-of-attachment work, ground plate, and OESC-compliant scope end to end, files the ESA permit, and schedules the inspection so your 200A service is ready for EV charging and future loads. The distinction matters for your budget. An electrical panel upgrade [/electrical-panel-upgrade/ →](/electrical-panel-upgrade/) deals with everything behind the meter. A service upgrade deals with the incoming supply itself: the weatherhead where the utility drop lands, the mast holding it, the meter base, the service conductors, and the grounding electrode system. If any of those are undersized or deteriorated, replacing only the panel leaves the actual bottleneck in place. Most homes that need this are pre-1980 builds on 60A or 100A overhead service, and the mast and meter base are usually the same age as the house. ## When do you actually need one? Three signals point to a full service upgrade rather than a panel swap. **Your service is 60A or 100A and your load calculation says the upgrade is real.** Not just “the panel looks full,” but an OESC Section 8 calculation showing the connected demand exceeds what the service can carry. **The mast, weatherhead, or meter base is deteriorated.** Corrosion, a loose point of attachment, a cracked meter socket, or a mast pulling away from the wall. None of that gets better, and the utility will flag it eventually anyway. **You are adding more than a car.** A heat pump, a second EV, a basement suite, an induction range, or a hot tub. Doing the service once with spare panel capacity is much cheaper than doing it twice. If none of those apply and you just need headroom for one charger, say so, and we will price an EV load management device [/load-management-system/ →](/load-management-system/) or a dedicated subpanel [/subpanel-installation/ →](/subpanel-installation/) instead. ### Common problems we solve - **Corroded or undersized service masts** on older Etobicoke, East York, and Toronto core homes. - **Failing meter bases** the utility has already tagged or flagged. - **Inadequate grounding.** Common in pre-1970 homes and corrected as part of the upgrade. - **60A services** that cannot support modern living, let alone a 48A continuous charger load. - **Heritage and restricted-access properties** where the mast route and point of attachment need planning rather than improvisation. ## How does the utility coordination work? This is the part homeowners dread, and it is entirely our job. We file the ESA permit and submit the service upgrade application to the utility that serves you: Toronto Hydro in the City of Toronto, Alectra Utilities across Mississauga, Brampton, Vaughan, Markham, and Aurora, Elexicon Energy through Durham and parts of York, and the local distributor in Oakville, Burlington, Milton, or Newmarket. The utility schedules a disconnect so we can work the mast and meter base safely, then reconnects once the ESA inspection is satisfied. That scheduling is what makes a service upgrade a 1 to 2 week job rather than a same-day one, and it is the single biggest variable in the timeline. On upgrade day the old mast and meter base come off, the new ones go up with a proper point of attachment, service conductors are pulled, a copper ground plate and bonding conductors are installed, and the new 200A panel goes in with labelled circuits. Power is back the same day in nearly every case. ## What does it cost across the GTA? A full 200A overhead service upgrade runs $3,500 to $5,500 CAD, including the mast, weatherhead, meter base, conductors, grounding, panel, ESA permit, and inspection. Bundled with the Level 2 charger install, most homes land between $5,000 and $7,300 CAD. Underground service laterals cost more because of trenching and conduit. Heritage properties, tight side yards, and restricted-access sites are quoted after inspection rather than off a price list, because the routing genuinely changes the labour. A whole-home surge protector is worth adding while the panel is open, both for the charger electronics and for everything else modern in the house. We quote it as its own line so you can decide. And the 2026 Home Renovation Savings program pays up to $5,000 CAD toward an eligible EV charger installation, which we file for you.

Why Us ## Why choose us for 200a service upgrade? ### Utility coordination is our job, not yours We file with Toronto Hydro or your local distributor and schedule the disconnect and reconnect around your day. ### Grounding brought to current code Older homes often have inadequate grounding. The upgrade is the right moment to fix it, and we include it. ### Scoped before it is quoted Mast, meter base, point of attachment, and conductor route all inspected before you see a number. ### Future loads planned for Heat pump, second EV, basement suite. We size the panel with spare spaces so the next project is a breaker, not another upgrade. ### Surge protection available A whole-home surge protector is a cheap add-on while the panel is open, and it protects the charger electronics too. ### Documented for insurance and resale The ESA Certificate of Acceptance is what your insurer and the next buyer's lawyer will look for. Process ## How does 200a service upgrade work? Four clear steps, with the ESA permit and inspection built into every one of them. 01 ### Service Assessment We check your existing service size, mast condition, meter base, and grounding, then give you a scope and a price band. 02 ### Permit and Utility Filing The ESA permit goes in and the disconnect and reconnect is booked with Toronto Hydro, Alectra, Elexicon, or your local distributor. 03 ### Upgrade Day Mast, weatherhead, meter base, service conductors, grounding, and the new 200A panel, all in one coordinated visit. 04 ### Reconnect and Certify Utility reconnects, ESA inspects, and the Certificate of Acceptance is handed to you for your records.

They handled Elexicon and the ESA inspection start to finish." Farah A. Pickering Village, Ajax FAQ ## 200A Service Upgrade questions, answered How much does a 200A service upgrade cost in Toronto? A full service upgrade including the mast, meter base, service conductors, grounding, and a 200A panel runs $3,500 to $5,500 CAD. Add the Level 2 charger install and most homes land between $5,000 and $7,300 CAD. Underground service laterals and restricted-access sites are quoted after inspection. What is the difference between a panel upgrade and a service upgrade? A panel upgrade replaces the breaker panel only, which works when the incoming service is already adequate. A service upgrade replaces the mast, weatherhead, meter base, and service conductors as well, and requires the utility to disconnect and reconnect you. Many older GTA homes need the full service upgrade, not just the panel. How long does a service upgrade take? The physical work is typically one full day. The schedule is set by the utility, since Toronto Hydro or your local distributor has to book the disconnect and reconnect. From approved quote to energized service is normally 1 to 2 weeks. Will I be without power for long? Expect the power off for most of the working day while the mast, meter base, and panel are replaced. We plan the window with you in advance so you can arrange around it, and the service is reconnected the same day in nearly all cases. Who coordinates with the utility? We do. Toronto Hydro for the City of Toronto, Alectra Utilities for Mississauga, Brampton, Vaughan, Markham, and Aurora, Elexicon Energy for Durham and parts of York, and the local distributor in Oakville, Burlington, Milton, or Newmarket. You do not need to make the call. Do I need a service upgrade or is load management enough? Load management under OESC Rule 8-106 solves a headroom problem for one EV charger. It does not solve an undersized or deteriorated service. If your mast is corroded, your meter base is failing, or you are planning electric heat or a second EV, the upgrade is the right answer. The load calculation and the physical inspection together decide it. Should I add surge protection while the panel is open? It is worth considering. A whole-home surge protector is far cheaper to install while the panel is already open, and it protects the sensitive electronics in an EV charger, a heat pump, and modern appliances. We will quote it as an optional line rather than bundling it in. Does a service upgrade need an ESA permit? Yes, without exception. Service upgrades require an Electrical Safety Authority permit and inspection, and the utility will not reconnect without the ESA approval in place. We file the permit, schedule the inspection, and hand over the Certificate of Acceptance. Still have a question about your panel or your charger?
