Public EV Charging Cost in Canada

Public DC fast charging can cost about 12× more per km than charging at home overnight - and the gap between networks is just as large. Here's what each one actually charges, converted to a real $/100 km figure.

home overnight (ULO)
$1.05/100km
gas (mid-size)
$14.87/100km
reference efficiency
18.5 kWh/100km

All public network figures below use this same 18.5 kWh/100km reference efficiency so networks are compared on a like-for-like basis - your actual vehicle's efficiency will shift these numbers up or down; see your model on the vehicle catalogue.

Network by network

NetworkOff-peakPeakEst. $/100km
Tesla Supercharger (Tesla vehicles)$0.28/kWh$0.51/kWh$9.44
Tesla Supercharger (non-Tesla via NACS)$0.45/kWh$0.72/kWh$13.32
Petro-Canada Electric Highway-$0.50/minDepends on charge rate
Electrify Canada-$0.50/kWh$9.25
Ivy Charging Network-$0.69/kWh$12.77
BC Hydro (reference, non-Ontario)-$0.31/kWh$5.74

Per-minute networks (like Petro-Canada Electric Highway) cost more per 100km for slower-charging vehicles and less for fast ones, since you're paying for time, not energy - the $/kWh networks above give a more predictable cost regardless of your vehicle's charge curve.

When public charging still makes sense

  • Road trips. You're paying for speed and coverage, not the cheapest possible electron - compare against the cost of stopping for gas instead, not against your home rate. Worked corridor: Toronto to Montreal charging. Plug adapters: NACS vs CCS.
  • No home charging. If you rent or live in a condo without assigned charging, public networks (ideally off-peak) are your baseline cost, not an occasional top-up - budget accordingly.
  • Tesla Supercharger access. Non-Tesla NACS access is priced higher than Tesla-owner rates on the same hardware - a Tesla-brand vehicle has a real, calculable cost advantage here, not just a network-size advantage.
