An EV charger installation begins with an electrical assessment of the property. A home EV charger draws a continuous load, and the existing service and electrical panel determine what the installation can support. The assessment sets the available capacity, the cable route and the notification requirements. The ten checks below cover what we review first.
Do I need to upgrade my panel for a home EV charger?
Not in every case. Some 100A services support a Level 2 charger with load management, once a load calculation confirms it.
How long does an EV charger installation take?
Many installations are completed within a few hours, depending on the equipment and site conditions.
Does an EV charger need its own circuit?
A Level 2 charger is normally supplied by a dedicated 240V circuit sized to the equipment.
Is a permit required in Ontario?
Work of this type is generally subject to Electrical Safety Authority notification, which we file.
A load calculation establishes what capacity remains after existing loads such as the furnace, range, dryer and air conditioner. A 200A electrical panel often has room, and some 100A panels do as well with load management. Spare breaker space and equipment condition are assessed at the same time. More on how Toronto homeowners prepare their electrical systems for EV charger installation.
The mounting position determines the cable route and the work involved. We review:
Charger output is matched to daily driving distance rather than the highest rating available. A 32A charger can restore roughly 40 km of driving in about an hour, though the rate varies with the vehicle, the equipment and site conditions. Two vehicle households and longer commutes may suit a 40A or 48A unit, subject to available capacity. Our breakdown of Level 1 vs Level 2 EV charging covers the calculation.
Both configurations can be installed in compliance with the requirements that apply to the equipment and the location. Hardwired units suit outdoor positions, support higher amperage and remove the receptacle as a point of failure. Plug-in units use a NEMA 14-50 receptacle and can be exchanged or relocated more easily, provided the receptacle is industrial grade. Outdoor and higher output installations are commonly hardwired.
Where a second vehicle is anticipated, provision can be made during the first installation. Options include a larger conduit, spare breaker capacity, or a feeder sized for a second EV charging station while walls are open. What is practical depends on the existing service and the scope of work. More in planning your home for long term EV ownership beyond the charger installation.
Outdoor equipment is selected for exposure to weather, and manufacturer specifications govern the ratings for a given unit.
An enclosure rating such as NEMA 4 or 4X for rain, snow and road salt
Cable temperature ratings suited to Ontario winters
A mounting height that keeps the connector clear of snow
Indoor installations still need clearance and a mounted cable holder

An EV charging station installation in Ontario is generally subject to Electrical Safety Authority notification, depending on the scope of work. We file the notification, an inspector reviews the installation, and a Certificate of Acceptance is issued once the work is accepted.
Smart chargers rely on a network signal at the mounting location, and garage signal strength is often weaker than elsewhere. We test the signal at the intended mounting point first. A detached garage may call for a mesh node or access point, and some units support an Ethernet or cellular connection. Without a reliable signal, scheduling and off peak charging may not function as intended.
Electrical work of this kind is carried out by a licensed electrical contractor, and the applicable requirements depend on the installation and the governing rules. A licence number, proof of insurance and a written scope of work are reasonable items to confirm first. Canadian Wire Wizards is a licensed electrical contracting company serving the GTA, established in 2018, owned and operated by Demetrois Alafogiannis, with more than 35 years of combined industry experience. We hold an ECRA/ESA electrical contractor licence and complete residential and commercial EV charging station installation. Our overview of electric car charger installation for homes and businesses in Toronto and the GTA sets out what a compliant installation includes.

An EV charger installation is only as sound as the assessment behind it. The electrical panel, the location, the notification requirements and the contractor’s licence are confirmed before work starts.
Pricing depends on panel capacity, cable run length and whether finished surfaces have to be opened.
Work of this type is generally subject to ESA notification in Ontario, and we file it.
Either can work. Outdoor units are selected with an enclosure rating suited to the exposure.
The work involves a dedicated 240V circuit and inspection requirements, so we recommend a licensed electrical contractor.
