In the ten defined utility scenarios below, an EV using 18 kWh/100 km adds about $1.76 to $3.44 in marginal electricity per 100 km at home. That range is not a promise about a household’s complete bill: rate plans, tiers, delivery, taxes and fixed charges differ.
Direct answer: multiply the vehicle’s kWh/100 km by the applicable cents/kWh and divide by 100. Public fast charging can cost much more, and time-based prices depend heavily on the energy the vehicle actually accepts.
Home EV charging cost by province: defined scenarios
| Province | Defined rate scenario | Rate | 18 kWh/100 km | Effective |
|---|---|---|---|---|
| Newfoundland and Labrador | NL Hydro diesel first block | 15.213¢ | $2.74 | 2026-01-01 |
| Prince Edward Island | Maritime Electric first 2,000 kWh | 17.840¢ | $3.21 | 2026-08-01 |
| Nova Scotia | NS Power standard variable charge | 19.128¢ | $3.44 | 2026-05-01 |
| New Brunswick | NB Power base plus variance energy charge | 15.840¢ | $2.85 | 2026-04-14 |
| Quebec | Hydro-Québec EV estimate, second tier with tax | 12.813¢ | $2.31 | 2026-04-01 |
| Ontario | OEB time-of-use off-peak energy price | 9.800¢ | $1.76 | 2025-11-01 |
| Manitoba | Manitoba Hydro standard variable charge | 9.970¢ | $1.79 | 2026-01-01 |
| Saskatchewan | SaskPower standard variable charge | 15.476¢ | $2.79 | 2026-02-01 |
| Alberta | DERS Rate of Last Resort energy-only price | 12.020¢ | $2.16 | 2025-01-01 |
| British Columbia | BC Hydro tier 1 energy charge | 11.870¢ | $2.14 | 2026-04-01 |
At 18 kWh/100 km, the same rate scenarios equal roughly $17.60–$34.43 per 1,000 km and $264–$516 for 15,000 km. At 22 kWh/100 km, multiply every result by 1.222. Charging losses are not added; drivers wanting a cautious budget can model 10% more energy.
Public charging is not one national price
| Public scenario | Published pricing | Comparable example |
|---|---|---|
| Petro-Canada DC fast | $0.50/minute | At 80 kW average, about $0.375/kWh effective |
| ChargePoint station | Owner-set: kWh, time, session or other | Check each station before starting |
| NRCan general guidance | Time, flat, kWh or combination | Pricing structures are not directly interchangeable |
Methodology and limitations
- Rates were verified September 10, 2026 and use one explicitly named utility scenario per province.
- Ontario uses off-peak commodity pricing; Alberta uses the default energy price; delivery and billing charges are excluded.
- Quebec’s EV example is the second-tier estimate including tax. Other rows generally exclude tax.
- The Newfoundland and Labrador row is an NL Hydro diesel-service scenario, not an island-wide average.
- No territorial comparison is presented because the approved scope is provincial and remote-system structures differ substantially.
For infrastructure rather than cost, see Motorz.ca’s highway charging redundancy analysis and Electric Vehicles hub.
