Electrical Service Upgrade in Toronto and GTA
Your electrical service is the connection between your home or business and the utility grid. If your home is still running on 100 amp service, it may not be able to handle today’s energy demands. At XBOCT (XB) Electric, we provide professional electrical service upgrades in Toronto and the GTA to ensure your property has the power capacity it needs — safely, efficiently, and fully code-compliant.
Frequently asked questions
How much does a 200 amp service upgrade cost in Toronto?
The cost of a 200 amp service upgrade in Toronto typically ranges from $2,500 to $5,000, depending on factors such as whether the service is overhead or underground, the location of your panel, and utility requirements. At XBOCT (XB) Electric, we provide a clear, upfront quote with no hidden fees.
What size service upgrade do I need—200 amp or 400 amp?
For most homes in Toronto, a 200 amp service upgrade is sufficient to power EV chargers, heat pumps, and modern appliances. Large homes, multi-unit dwellings, or properties with high demand may require a 400 amp service upgrade. We calculate your load to recommend the right size.
How long does an electrical service upgrade take?
Most electrical service upgrades in the GTA are completed in one day. Power is disconnected in the morning, upgraded by our licensed electricians, inspected by the ESA, and restored the same day.
Can I upgrade from 100 amp to 200 amp service without changing my panel?
In most cases, no. Upgrading from 100 amp to 200 amp service usually requires a new panel, since older panels are not designed to handle the higher capacity or may lack the necessary breaker space. In rare cases where the existing panel is compatible, we can upgrade without replacement — but this is uncommon. During our consultation, we’ll assess your setup and recommend the safest solution.
Do I need a permit for a service upgrade in Ontario?
Yes,. The first step is to apply to your local distribution company (such as Toronto Hydro, Hydro One, or Alectra) to obtain their approval and specific requirements. The next step requires an ESA permit and inspection.
XBOCT (XB) Electric handles the entire process for you—from utility applications and paperwork to permits and inspections—so you don’t have to worry about compliance.
