Ontario’s Ultra-Low Overnight price plan charges 3.9¢ per kWh from 11 p.m. to 7 a.m. and 39.1¢ on weekday evenings. For EV drivers that gap is huge, but condo and apartment residents can’t always choose the plan. Here is what the OEB says, who can switch, and how to time your charging. Not electrical or legal advice.
These are the Ontario Energy Board prices set for November 1, 2025. They apply until October 31, 2026; the OEB sets new prices every November 1. Source: OEB electricity rates.
| ULO period | When | Price (¢/kWh) |
|---|---|---|
| Ultra-Low Overnight | Every day 11 p.m. – 7 a.m. | 3.9 |
| Weekend Off-Peak | Weekends and holidays 7 a.m. – 11 p.m. | 9.8 |

For comparison, the OEB’s Time-of-Use prices are 9.8, 15.7 and 20.3¢, and Tiered prices are 12.0 and 14.2¢. Holidays follow the OEB holiday schedule.
| How your suite is billed | Can you pick ULO? | What to do |
|---|---|---|
| Your own account with the local utility (for example Toronto Hydro) | Usually yes, with a smart meter on the Regulated Price Plan | Ask your utility for the election form |
| Unit sub-meter provider (your own meter, but the bill comes from a company that isn’t the utility) | No — the OEB says only the building’s principal consumer can choose | Ask your property manager or board |
| Hydro included in rent or fees | Not your choice | Agree how EV electricity is paid before you plug in |
| Energy retailer contract | Not while on contract | Check your contract |

ULO only helps if the charging circuit is on your meter. Many condo stalls are fed from the building’s common panel. In that case the board or landlord decides how charging is billed, often a flat fee or a separate EV meter. Ask before you assume overnight savings. More: who pays for the outlet and the power.
A simple example on the Electricity line only, for 30 kWh of charging:
Delivery, regulatory charges and HST are extra. A 32 A charger on 240 V supplies about 7.7 kW, so the 8-hour overnight window can cover a lot of daily driving; your car’s onboard charger may limit the speed.
For November 1, 2025 to October 31, 2026, the OEB’s Ultra-Low Overnight price is 3.9¢ per kWh every day from 11 p.m. to 7 a.m. The OEB sets new prices every November 1, so check the OEB page for the current number.
If your bill comes from an electricity utility, you can usually switch by sending your utility an election form. If your bill comes from a unit sub-meter provider, the OEB says you can’t switch; only the building’s principal consumer, usually the property manager, landlord or condo board, can choose for the whole building.
The weekday on-peak price, 4 p.m. to 9 p.m., is 39.1¢ per kWh, ten times the overnight price. Set your charger or car to start after 11 p.m. so you don’t plug in at peak by accident.
No. The OEB says there is no guarantee you will save by switching. ULO suits people who can move most use, including EV charging, overnight. If you use a lot of power on weekdays between 4 and 9 p.m., ULO can cost more.
No. That is the Electricity line price. Your bill also includes delivery, regulatory charges and HST, so your real cost per kWh is higher.
