From $1,500 CAD, subpanel installed [Subpanel Installation for EV →](/subpanel-installation/) ### Load Management (EVEMS) Installation DCC-9, DCC-12, Black Box, or SimpleSwitch EVEMS installation under OESC Rule 8-106 using current-transformer clamps to shed the EV load when household demand peaks. The affordable alternative to a full panel upgrade on many 100A homes. From $500 CAD, device installed [Load Management (EVEMS) Installation →](/load-management-system/) Compare paths ## Panel Upgrade vs Service Upgrade vs EVEMS Load Management Three different paths to adding EV charging capacity. The right one depends on your load calculation, service size, and how much of the house is on the panel. | Path | Typical cost | Timeline | When it fits | | --- | --- | --- | --- | | DCC-9 or DCC-12 EVEMS | $500 to $1,200 | Same day | 100A home with panel space, occasional peaking | | Dedicated subpanel | $1,500 to $2,800 | 1 day | Main panel has kW capacity but no breaker space | | 100A to 200A panel upgrade | $2,500 to $4,500 | 1 day + inspection | Load calc exceeds 100A even with EVEMS | | Full 200A service upgrade | $3,500 to $5,500 | 1 to 2 weeks | Mast, meter base, or utility feeder is the bottleneck | ## Not sure which electrical path fits your home?

A 100A to 200A panel swap runs $2,500 to $4,500 CAD in Toronto and the GTA, covering the new panel, breakers, OESC Section 8 load calculation, ESA permit, and inspection. A full service upgrade with new mast and meter base adds $3,500 to $5,500 CAD because it involves Toronto Hydro or Alectra disconnect and reconnect work. Combined with a Level 2 EV charger install, most homes land at $4,000 to $7,300 CAD. What is the difference between a panel upgrade and a service upgrade? A panel upgrade replaces the breaker panel inside your home, keeping the existing service mast, meter base, and utility feeder. A service upgrade replaces everything from the utility point of attachment down: mast, meter base, service entrance cable, ground plate, and often the panel too. Panel upgrades take 1 day; service upgrades take 1 to 2 weeks because the utility has to schedule a disconnect and reconnect. Do I need a permit for an electrical panel upgrade in Ontario? Yes. Every panel or service upgrade in Ontario requires an Electrical Safety Authority permit, an OESC Section 8 load calculation, and an ESA inspection with a Certificate of Acceptance issued at close-out. That Certificate of Acceptance is what your home insurer, mortgage lender, and any future buyer will ask for. We file the permit and coordinate the inspection as part of every quote. How do I know if I need a panel upgrade or a load management device? It depends on the load calculation. If your existing service has spare kW capacity but no physical breaker space, a subpanel is often the cheapest answer. If the service is genuinely at capacity, a load management device (DCC-9 or DCC-12 under OESC Rule 8-106) sheds the EV load when the house peaks, satisfying code without an upgrade. A full 100A to 200A upgrade is warranted when the load calculation exceeds 100A even with an EVEMS device installed. Which GTA utilities do you coordinate service upgrades with? Toronto Hydro (City of Toronto), Alectra Utilities (Mississauga, Brampton, Vaughan, Markham, Aurora), Oakville Hydro (Oakville), Burlington Hydro (Burlington), Elexicon Energy (Ajax, Whitby, Pickering, Richmond Hill), Newmarket-Tay Power, and Hydro One in outlying communities. We file the service upgrade application, coordinate the disconnect and reconnect date, and schedule the ESA inspection around the utility timeline. How long does a panel upgrade take on install day? A 100A to 200A panel swap with no service upgrade takes 6 to 10 hours on install day, plus the ESA inspection typically within 24 to 72 hours. Your power is out for 4 to 6 of those hours while we swap the panel. A full service upgrade with mast and meter base takes 1 to 2 weeks total because it depends on the utility disconnect and reconnect window. Still have a question about your panel or your charger?
