How Much Does It Cost to Run a Crypto Mining Rig in Ontario? (2026)
A mining rig runs flat out around the clock. Even a single-GPU setup at 500 watts uses more electricity than most whole households, and an ASIC miner at 3,000 watts uses as much as a dozen fridges.
A typical crypto mining rig (1,500 W) costs C$0.22 per hour, or about C$161.57 per month at 24 hours a day in Ontario. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 500 W | C$0.075 | C$1.80 | C$53.86 | C$655.25 |
| Typical 1,500 W | C$0.22 | C$5.39 | C$161.57 | C$1,966 |
| High 3,500 W | C$0.52 | C$12.57 | C$376.99 | C$4,587 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 13,140 kWh per year.
One hour of a crypto mining rig (1.5 kWh) is the same electricity as
- 8.3km in an electric car
- 15hours of TV
- 33hours of a laptop
- 167hours of an LED bulb
In Ontario, with electricity at 15.0¢ per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical crypto mining rig costs C$0.22 per hour and about C$1,966 per year at 24 hours a day. That is about 7% more than the national average for Canada (C$151.20 per month), because electricity in Ontario costs 15.0¢ per kWh against 14.0¢ nationally. Each C$1.00 of electricity buys roughly 4.5 hours of use.
How to lower the cost of running a crypto mining rig
- Calculate the electricity cost per day before anything else. It decides whether mining makes money at all.
- Undervolt GPUs. It often cuts power by 20 to 30 percent with little hash rate loss.
- Vent the heat outdoors in summer. Cooling the room adds to the bill.
