Ontime Electric upgrades Toronto homes from 100 amp to 200 amp electrical service — including the new 200 amp panel, service entrance work as required, ESA Notification of Work, and coordination of the utility disconnect and reconnect with Toronto Hydro or your local utility. We are a licensed electrical contractor (ECRA/ESA Licence #7009495) with over 20 years of experience in Toronto and a 4.9-star Google rating, 4.8 on HomeStars.

Signs You May Need a 200 Amp Upgrade

  • Frequent breaker trips when major appliances run at the same time
  • Installation of a Level 2 EV charger, heat pump, hot tub, or home addition
  • Insurance concerns about an older electrical service or fuse panel
  • An outdated 60-amp service or fuse-based electrical system
  • Planned major renovations or a new basement apartment

Not every home needs 200 amps. We perform a load calculation first and recommend an upgrade only when your home’s electrical demand and future plans justify it.

What’s Included in a 100 Amp to 200 Amp Service Upgrade?

Typical 100 amp to 200 amp service upgrades in Toronto fall within $1,700–$4,500, with the exact cost depending on your existing electrical service, panel condition, utility requirements, accessibility, and scope of work. Your written quote confirms the price before work begins. For a full breakdown of 200 amp service upgrade cost factors, see our panel upgrade cost guide.

Included in a 100→200A upgrade

  • Load calculation and capacity assessment
  • New 200 amp panel with new breakers
  • ESA Notification of Work
  • Utility disconnect/reconnect coordination
  • Required ESA review/inspection and Certificate of Acceptance after approval
  • Upfront written quote

What Affects the Cost?

  • Service entrance work: mast, service cable, meter base condition
  • Overhead vs. underground electrical service
  • Panel relocation, if required
  • Grounding or bonding corrections found during assessment
  • Utility-side fees, where applicable
  • Older wiring issues identified during assessment

Our 100 to 200 Amp Upgrade Process

  • Step 1: Assessment & load calculation — we confirm your current electrical capacity and what your home actually needs.
  • Step 2: Written quote — you receive the full price and scope before work begins.
  • Step 3: ESA Notification of Work — we file the required electrical notification.
  • Step 4: Utility coordination — we coordinate the required service-upgrade and disconnect/reconnect process with Toronto Hydro or your local utility. If the utility requires owner authorization or payment, we let you know in advance.
  • Step 5: Installation — on-site electrical work for a straightforward upgrade is often completed in one working day, depending on site conditions and utility scheduling.
  • Step 6: ESA inspection & utility connection — ESA completes the required service inspection and provides connection authorization to the utility. Once the installation is accepted, you receive a copy of the ESA Certificate of Acceptance.

200 Amp Service Upgrades for Toronto Homes

Electrical service upgrades can be very different depending on the age and layout of the home:

  • East York and Scarborough: post-war bungalows may still have original 60 or 100 amp electrical services
  • Toronto’s older west-end neighbourhoods: Victorian and Edwardian semis can require additional attention to the service entrance and grounding
  • Older wartime homes: panel locations and existing wiring can make access more complicated
  • Newer infill homes: EV chargers, heat pumps, electric appliances, and other modern loads can push existing service capacity

More than 20 years of Toronto-specific electrical work means we assess the actual service, wiring, access, and load requirements of your home rather than treating every upgrade the same.

ESA Permits and Toronto Hydro Coordination

A 100 amp to 200 amp electrical service upgrade requires an ESA Notification of Work. The completed installation must also go through the required ESA inspection and approval process before the utility completes the service connection. Toronto Hydro has its own service-upgrade process, and other GTA utilities may have different connection requirements.

We file the ESA notification and coordinate the required utility steps as part of the project. A quote that excludes the required ESA notification should be treated as a red flag. Once the work is reviewed and accepted, ESA issues a Certificate of Acceptance, which is important documentation for insurance and resale.

Insurance and Resale Value

Some insurers may ask about an older electrical service, fuse panel, or previous electrical upgrades. A properly completed 200 amp service upgrade with an ESA Certificate of Acceptance provides documentation that the work was reviewed and accepted under the Ontario Electrical Safety Code.

When selling a home, buyers planning EV chargers, heat pumps, hot tubs, or other high-demand electrical equipment may also ask about electrical service capacity. A documented 200 amp upgrade gives them a clear answer.
