Apartment vs House Electricity Cost Estimator (Ontario)
Compare typical monthly electricity usage for different home types in Ontario.
Updated 2026‑04‑22
This simple estimator helps you compare typical electricity usage patterns for different types of homes in Ontario. Actual usage varies by insulation, heating type, number of occupants, and appliance efficiency — but these ranges reflect common patterns seen across the province.
Note: This tool estimates only the usage portion of the bill. Delivery, regulatory charges, and taxes are additional.
How to interpret the results
The number you see above reflects the Electricity/Usage portion of your bill — the part based on kWh. Your final bill will also include:
- Delivery charges — cost of poles, wires, transformers, and system operations
- Regulatory charges — system oversight and program costs
- Global Adjustment — system‑wide cost recovery
- HST
These additional components often mean the total bill is higher than the usage estimate alone.
Typical usage ranges in Ontario
While every home is different, these ranges are common across the province:
- Small apartment: 300–450 kWh
- Large apartment: 500–700 kWh
- Townhouse: 800–1,000 kWh
- Detached home: 1,200–1,800 kWh
- Electric‑heated home: 2,000–3,500 kWh (winter)
Heating type is the biggest driver of variation. Electric heat can double or triple winter usage.
