Question 1

How much does an electrical panel upgrade cost?

Accepted Answer

In the Greater Toronto Area, a residential 100A to 200A electrical panel and service upgrade typically ranges between $2,800 and $5,200 CAD, with standard projects averaging $3,400 to $4,200 CAD. This includes Licensed Electrical Contractor (LEC) labour, new 200A panelboard with modern breakers, whole-home surge protection, grounding electrodes, the Electrical Safety Authority (ESA) permit, and local utility (Toronto Hydro, Alectra, Elexicon, or Hydro One) coordination fees.

Question 2

How long does the upgrade take?

Accepted Answer

The actual on-site electrical installation is completed in a single day, usually taking between 6 and 8 hours. Power is isolated at the utility meter in the morning (typically around 8:30–9:00 AM) and restored the same afternoon (usually by 2:30–4:30 PM) once the ESA inspector provides connection authorization to your local utility dispatch.

Question 3

Do I need a panel upgrade if I'm installing an EV charger?

Accepted Answer

Not necessarily, but it depends on your current calculated electrical load under OESC Rule 8-200. A continuous Level 2 EV charger (typically 32A to 48A) on an older 100A service often pushes the panel over capacity if you also have an electric dryer, range, or air conditioner. In that case, you either need a 200A panel upgrade or an approved Electric Vehicle Energy Management System (EVEMS) load-shedder like a DCC.

Question 4

What size panel do I need (100A or 200A)?

Accepted Answer

A 200-amp panel is now the standard requirement for modern residential electrification across Ontario. While 100A was sufficient for traditional gas-heated homes with basic appliances, homes adding Level 2 EV chargers, high-efficiency heat pumps, induction cooking, or basement rental suites require the 40 to 60 breaker slots and 48,000-watt capacity of a 200-amp service.
