The Real Question Every Ontario EV Owner Asks
If you've recently bought an electric vehicle—or you're considering one—you've probably wondered about charging costs. Should you install a home charger, or just rely on the public charging network around the GTA?
As electricians who install EV chargers across Ontario every week, we hear this question constantly. The answer isn't complicated once you see the actual numbers.
What Public Charging Actually Costs in Ontario
Public charging stations across the GTA vary widely in pricing. Here's what you'll typically pay:
Level 2 Public Chargers (6–10 hours for full charge):
- Free stations: Still exist at some malls and municipal lots, but increasingly rare
- Paid stations: $1.50–$2.50 per hour, or $0.20–$0.35 per kWh
DC Fast Chargers (20–45 minutes to 80%):
- Electrify Canada: $0.27–$0.50 per minute depending on power level
- Petro-Canada: Around $0.33 per minute
- Tesla Superchargers: $0.36–$0.50 per kWh for non-members
For a typical EV with a 60 kWh battery, a DC fast charge from 20% to 80% costs roughly $18–$30. Do that twice a week, and you're looking at $150–$250 monthly.
Level 2 public charging is cheaper but less practical. You're paying for parking, waiting around, and often competing for available plugs during peak hours.
What Home Charging Costs in Ontario
Home charging math is straightforward once you understand Ontario's electricity rates.
Time-of-Use Rates (as of late 2024):
- Off-peak: $0.076 per kWh
- Mid-peak: $0.122 per kWh
- On-peak: $0.158 per kWh
Most EV owners charge overnight during off-peak hours. For that same 60 kWh battery charged from 20% to 80%:
- Home charging at off-peak: Approximately $2.75–$3.00
- Public DC fast charging: $18–$30
That's roughly 85–90% savings per charge session.
Over a year, assuming you drive 20,000 km and your EV uses about 18 kWh per 100 km, you'd consume around 3,600 kWh. At off-peak rates, that's approximately $275 annually. The same usage at public fast chargers could run $1,500–$2,500.
The Upfront Cost of Home EV Charger Installation
Home charging requires an initial investment. Here's what GTA homeowners typically pay:
Level 1 Charging (standard 120V outlet):
- Cost: $0 if you already have an outdoor outlet
- Reality: Adds only 5–8 km of range per hour—impractical for most drivers
Level 2 Charging (240V hardwired or NEMA 14-50 outlet):
- Charger unit: $500–$1,200 for quality brands
- Installation: $800–$2,500 depending on panel distance, wiring complexity, and permit requirements
- Total: $1,300–$3,700
If your home's electrical panel is older or at capacity, you may need a panel upgrade before installation. This adds $2,000–$4,500 but also future-proofs your home for additional electrical loads.

Permits and ESA Requirements in Ontario
This is where many homeowners get confused—or make costly mistakes.
In Ontario, any EV charger installation involving new circuits requires an Electrical Safety Authority (ESA) permit. This isn't optional. It's provincial law.
A licensed electrical contractor pulls the permit, completes the work to Ontario Electrical Safety Code standards, and arranges ESA inspection. The permit fee is typically $100–$150, included in most professional installation quotes.
Why this matters:
- Unpermitted work can void your home insurance
- It creates problems when selling your home
- Improperly installed chargers pose fire risks
We've been called to fix DIY installations and work done by unlicensed handymen. It usually costs more to correct than doing it right the first time.
Breaking Down the Payback Period
Let's do simple math for a GTA homeowner:
Assumptions:
- Annual driving: 20,000 km
- Public fast charging cost: $1,800/year
- Home charging cost: $275/year
- Annual savings: $1,525
- Installation cost: $2,200 (mid-range)
Payback period: Under 18 months
After that, you're saving over $125 monthly—indefinitely. The charger itself typically lasts 10+ years with minimal maintenance.
If you also needed a panel upgrade, payback extends to 3–4 years. But that upgrade adds value to your home and supports future electrical needs like heat pumps, hot tubs, or additional EVs.
Convenience Factors Beyond Cost
Money aside, home charging changes your daily routine.
You plug in when you get home, like charging your phone overnight. Every morning starts with a full battery. No apps to check, no detours to charging stations, no waiting in parking lots.
Public charging works for road trips and emergencies. As your primary charging method, it's inconvenient and expensive.
Practical Tips From the Field
After hundreds of installations across the GTA, here's what we tell homeowners:
Choose a charger with more capacity than you need today. A 48-amp unit costs slightly more than 32-amp but charges faster and handles future EVs with larger batteries.
Install in your garage if possible. Weather protection extends equipment life and simplifies wiring runs.
Consider future panel capacity. If you're planning any major electrical additions in the next five years, address panel limitations now rather than paying for two separate projects.
Get multiple quotes. Pricing varies significantly. But beware quotes that seem too cheap—they often skip permits or use undersized wiring.
The Bottom Line for Ontario Homeowners
Comparing home EV charging vs public charging Ontario cost isn't close. Home charging wins on price, convenience, and long-term value.
The upfront installation cost pays for itself quickly—often within 18 months. After that, you're keeping $1,500+ annually that would otherwise go to charging networks.
