How Much Does It Cost to Run a Sump Pump in Ontario? (2026)
A sump pump draws 400 to 1,500 watts but only runs when the pit fills. In dry seasons that may be minutes a day; in a wet spring it can run for hours.
A typical sump pump (800 W) costs C$0.12 per hour, or about C$1.80 per month at 0.5 hours a day in Ontario. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (400 W) | C$0.060 | C$0.030 | C$0.90 | C$10.95 |
| Typical (800 W) | C$0.12 | C$0.060 | C$1.80 | C$21.90 |
| High (1,500 W) | C$0.22 | C$0.11 | C$3.38 | C$41.06 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.5 h/day ≈ 146 kWh per year.
One hour of a sump pump (0.80 kWh) is the same electricity as
- 4.4km in an electric car
- 8.0hours of TV
- 18hours of a laptop
- 89hours of an LED bulb
In Ontario, with electricity at C$0.15 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical sump pump costs C$0.12 per hour and about C$21.90 per year at 0.5 hours a day. That is about 7% more than the national average for Canada (C$1.68 per month), because electricity in Ontario costs C$0.15 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 8.3 hours of use.
How to lower the cost of running a sump pump
- Fix grading and gutters so less water reaches the pit in the first place.
- Check the float switch. A stuck float can run the pump continuously.
- Size the pump correctly. An oversized pump short-cycles and wears out.
Frequently asked questions
How much does a sump pump cost to run?
About 0.4 kWh a day at 30 minutes of run time. Far more during storms.
