Level 1 charging is the cord that came with the car, plugged into an ordinary 120 V outlet. Natural Resources Canada rates it at 3 km to 8 km of range for every hour the car is plugged in. Whether that is enough is arithmetic rather than opinion. Multiply the band by the hours your car actually sits at home overnight, then compare the answer to the distance you drive in a day. For most plug-in hybrids in Barrie it clears. For a battery EV on a Highway 400 commute it usually does not.
The two levels, side by side
Barrie Electrical Co. gets asked this before nearly every quote. The numbers below are Natural Resources Canada’s, not ours.
| Charging level | Input | Range added per hour |
|---|---|---|
| Level 1 | 120 V | 3 km to 8 km |
| Level 2 | 208/240 V | 16 km to 50 km |
The EV chargers page on this site quotes 8 km per hour for Level 1, which sits at the top of that federal band. The Electrical Safety Authority describes Level 2 as having about the same requirement as a stove or a dryer, at 240 Volts and 30 Amps. That difference in input is the whole reason for the difference in speed.
Your rate plan sets the length of the window
On Level 2 the price plan barely matters, because the charger finishes inside any cheap window a plan offers. Level 1 cannot finish, so the plan becomes the constraint. The Ontario Energy Board sets the residential prices, and the two overnight windows are different lengths:
| Plan | Cheapest window | Price |
|---|---|---|
| Ultra-Low Overnight | Every day, 11 p.m. to 7 a.m. | 3.9 cents per kWh |
| Time-of-Use off-peak | Weekdays, 7 p.m. to 7 a.m. | 9.8 cents per kWh |
Ultra-Low Overnight is the cheaper rate and the shorter window. Time-of-Use off-peak is the dearer rate and the longer one. On Level 2 that trade is about money. On Level 1 it is about kilometres, because the hours you lose are hours the car was going to spend charging.
Ultra-Low Overnight also punishes anyone who plugs in after work: weekdays from 4 p.m. to 9 p.m. it charges 39.1 cents per kWh. Alectra Utilities bills Barrie and InnPower bills Innisfil, and both bill residential customers on the same Ontario Energy Board price plans, unless you have signed a contract with an energy retailer.
The circuit is the part that goes wrong
A Level 1 cord set draws steadily for hours. That is a different demand from a kettle, and it is why every page on this site says the same thing about it: the outlet must be on a dedicated circuit.
Working as electricians in Barrie, we see the alternative in garages across the city. The car shares a circuit with a chest freezer, a compressor and the workshop lights, the breaker gives up in the middle of the night, and the driver finds out in the morning. The fault is not the charger.
Extension cords and power bars are worse again. During its Toronto charging blitz the Electrical Safety Authority found more than 400 instances of work done without a permit, along with extension cords run across sidewalks and chargers mounted on trees. Those are the failure modes of treating a charger as an appliance rather than as a circuit.
Barrie winters shorten the same window
Natural Resources Canada attaches a footnote to its own figures: range per hour of charging varies with the vehicle, the battery, the charger and fluctuating temperatures. In practice that means you plan a Barrie winter against the low end of the band and not the high end.
The one Level 1 habit worth adopting is scheduled departure. If your car supports it, set it while the cord is still connected, so as much of the warming as the cord can supply comes from the cord rather than from the battery. On Level 2 that energy is trivial. On Level 1 it is a meaningful share of the night.
When Level 1 stops being enough
Four signals, and any one of them is enough:
- Your daily distance is above what the window returns. Do the multiplication once and stop guessing.
- You drive a battery EV rather than a plug-in hybrid.
- The car is parked at home for fewer hours than the cheap window is long, because of shift work or a second job.
- There are two EVs in the driveway. One Level 1 circuit does not serve two cars.
At that point the question stops being about an outlet and becomes a question about the panel. Barrie Electrical Co. runs the Canadian Electrical Code Section 8 calculation before quoting a Level 2 EV charger installation in Barrie, because the service capacity decides the job far more often than the charger does. Our guide to putting an EV charger on a tight 100 amp service sets out both honest routes, load management and a service upgrade.
What a Level 1 circuit costs to have run
That same guide puts a dedicated Level 1 circuit at $300, and it is the cheapest experiment available to anyone unsure about Level 2. Ask what the figure covers before you accept it. A new branch circuit is notifiable work in Ontario, the ESA fee on a residential job lands between $120 and $300, and a quote that quietly leaves it out is not the number you will pay. The guide to ESA inspection costs in Ontario sets out what that notification is worth on resale and to an insurer.
Run the circuit, drive on it for a month, and let the odometer decide. If Level 1 covers your week, you have spent the smallest amount available. If it does not, you already have a proper outlet in the garage and a real number to size a panel upgrade in Barrie around.
