Complete Guide: Installing an EV Charger at Home in Ontario

Ontario is one of the fastest-growing EV markets in Canada, and with good reason — the province has robust rebate programs, expanding charging infrastructure, and a growing selection of EVs from every major manufacturer. If you've just bought an EV or are about to, installing a Level 2 home charger should be your next step.

Level 1 vs Level 2: Why it matters

Your EV came with a Level 1 charging cable — the kind that plugs into a standard 120V outlet. It works, but slowly: you're adding roughly 8 km of range per hour. For a 60 kWh battery pack, a full charge from empty takes over 60 hours.

A Level 2 charger uses a dedicated 240V circuit (like your dryer or electric range). It adds 25–40 km of range per hour, meaning most EVs charge fully overnight. For daily commuters, this is the difference between waking up to a full battery every morning and managing range anxiety.

Choosing the right Level 2 charger

Most home Level 2 chargers deliver 7.2–11.5 kW of power. Unless your EV's onboard charger accepts more than 7.2 kW (which most don't), a 32-amp charger is sufficient for the majority of households. Key factors:

• Amperage: 16A (slower, lower cost) to 48A (faster, requires larger breaker)
• Smart features: Wi-Fi scheduling, usage tracking, load management
• Indoor vs outdoor rating: Most quality units are weather-rated for outdoor use
• Cable length: 20–25 ft gives you flexibility in garage placement
• Brand reliability: ChargePoint, JuiceBox, Enel X, and Tesla Wall Connector all have strong track records

Does my panel support an EV charger?

This is the most common question we get. The answer depends on your current panel capacity and what other high-draw appliances you're already running. A 200-amp panel in a typical GTA home can almost always accommodate a 40-amp EV circuit without an upgrade. A 100-amp panel may need assessment — some can handle it, many can't.

The permit process in Ontario

Under Ontario Regulation 570/05, a dedicated EV charger circuit is considered electrical work requiring an ESA (Electrical Safety Authority) permit. Any licensed electrical contractor can pull this permit on your behalf — and should. Unpermitted EV charger installations can create problems with your homeowner's insurance and are illegal.

What to expect on installation day

• Your electrician will assess the panel and determine the best circuit routing
• A dedicated 240V circuit is run from your panel to the charger location
• The charger is mounted and hardwired (or plugged in, depending on the model)
• Your electrician connects the smart charger to Wi-Fi if applicable
• ESA inspection is scheduled (usually within 1–3 business days)
• You receive a certificate of inspection confirming all work is code-compliant
