How Many kWh Does a House Use in Ontario?

Ontario, Canada’s most populous province, uses significant electricity in its residences. The question that often arises is, how many kWh does a house use in Ontario? The average Ontario household uses approximately 7500 kilowatt-hours (kWh) of electricity annually. However, if you’re curious to understand what’s behind this figure, stick around as we delve into the finer details of electricity consumption in Ontario homes.

The Scope of Electricity Consumption in Ontario

Understanding kWh and Average Electricity Consumption

Firstly, let’s understand the term kWh. A kilowatt-hour (kWh) is a measure of energy that represents the amount of power equivalent to one kilowatt (1 kW) in usage for one hour. In household terms, if you run a 1000-watt appliance for one hour, you consume 1 kWh of electricity.

The average household electricity consumption in a home can vary significantly depending on factors like the size of the house, the number of occupants, the types and efficiency of electrical appliances used, and lifestyle habits. Canadian households have diverse energy consumption patterns, given the different energy needs across the country.

Electricity Costs and Bills

Understanding electricity costs is essential to comprehend your average electricity bill. The price per kWh in Ontario fluctuates throughout the day, with off-peak, mid-peak, and on-peak rates. This time-of-use pricing model can significantly impact your electricity bills.

In addition to the kWh used, the total cost of an electricity bill in Ontario includes delivery charges, regulatory charges, and taxes. As a residential utility customer, it’s essential to understand these factors when examining your electricity bills.

Average Annual Electricity Consumption in Ontario

Ontario’s Independent Electricity System Operator (IESO) data shows that the average Ontario household consumes about 7500 kWh of electricity per year. This figure represents the total energy consumption for lighting, using appliances, and heating or cooling the home.

The Role of Natural Gas

Natural gas plays a significant role in Ontario’s energy profile, particularly for heating purposes. Many Ontario homes use natural gas for heating and water heater operations.

While this doesn’t contribute directly to electricity consumption, it forms a substantial part of the average energy usage of an Ontario home.

Impact of Seasonal Variation

How much electricity a home uses can also vary by season. Due to heating requirements, Ontario’s cold winters often mean higher energy usage during these months.

Factors that Affect Your Average Energy Consumption

Understanding the factors that affect your average energy consumption is critical to managing your energy bills and identifying opportunities for savings. Let’s explore some of these key influences.

Home Size and Occupancy

The size of the average house is a significant factor that affects energy consumption. Naturally, larger homes consume more energy due to increased space that needs lighting, heating, and cooling. The number of people living in the house also matters. More occupants typically mean more usage of appliances, lights, and heating or cooling systems, leading to higher kWh per person.

Energy Source

The source of energy your home uses for heating can also significantly impact your average energy consumption. Many homes in Ontario use natural gas for heating due to its efficiency and relatively low cost compared to electricity. Using natural gas for heating can lower your electricity consumption, as can using high-efficiency electric heat pumps.

Appliance Use and Efficiency

The type and efficiency of appliances in your home significantly impact how many kWh of electricity you consume. Older, less efficient appliances typically use more energy than newer, energy-efficient models. Additionally, the frequency and manner of appliances used can significantly influence energy consumption. For example, running an older model refrigerator or washing machine can lead to high energy bills.

Climate and Weather

Ontario’s seasonal climate significantly affects your home’s average energy consumption. In colder months, the demand for heating rises, increasing energy use. Similarly, hot summers lead to increased use of air conditioning systems, again contributing to more significant energy usage.

Electricity Prices

Electricity prices can indirectly affect your energy consumption. When prices are high, one may incentivize households to use less electricity to save on energy bills.

Ontario’s time-of-use pricing can influence when households use electricity, with many opting to run significant appliances during off-peak hours when electricity prices are lower.

Behavior and Lifestyle

The average household’s occupants’ behavior and lifestyle significantly impact energy consumption. Habits like leaving lights on in unoccupied rooms, taking long hot showers, and using appliances during peak energy times can lead to higher energy use.

By slightly modifying these behaviors, such as using energy during off-peak times, turning off unnecessary lights, and investing in energy-efficient appliances, households can significantly reduce their energy consumption.

In conclusion, several factors can influence your average energy consumption, from the size and occupancy of your house to your appliances’ efficiency and usage habits. By understanding these elements, you can make informed decisions to reduce your energy consumption and, as a result, your energy bills.

Strategies to Reduce Electricity Consumption

Electricity consumption is a significant consideration for any household, not only from a cost perspective but also considering environmental impacts. Here, we explore several strategies to help you reduce how much electricity your home consumes, save money, and contribute to a more sustainable lifestyle.

Optimize Heating and Cooling

The heating and cooling of your home can constitute a significant portion of your energy use. Ensuring your home is well insulated can reduce the need for excessive heating or cooling.

Additionally, smart thermostats can regulate your home’s temperature more efficiently, reducing kWh usage. Using natural gas for heating instead of electricity can lower your household’s total electricity consumption.

Upgrade Your Appliances

Older appliances tend to be less efficient, consuming more electricity than necessary. Upgrading to energy-efficient appliances, such as Energy Star-rated devices, can reduce the amount of electricity used. It applies to all appliances, including refrigerators, dishwashers, washing machines, and smaller devices like televisions and computers.

Efficient Lighting

Switching to energy-efficient lighting, such as LED or compact fluorescent lamps (CFLs), can also reduce electricity use. These bulbs use significantly less electricity than traditional incandescent bulbs and last much longer, saving you money over your lifetime.

Water Heating

Your water heater can be a significant electricity consumer, especially if it’s an older, less efficient model. Switching to a more energy-efficient water heater, or using alternatives like solar water heaters or natural gas heaters, can help reduce how much kWh your home uses.

Also, lowering the thermostat on your water heater to a more moderate setting, like 120°F (49°C), can save electricity.

Use Renewable Energy Sources

Consider using renewable energy sources like solar panels to generate electricity. These systems can reduce your dependence on the grid, potentially lowering how much electricity you need to buy. With net metering programs, you can sell excess electricity back to the grid, reducing your energy bills further.

Energy Audit

Consider having a home energy audit conducted. This assessment can identify energy-inefficient areas in your home and recommend improvements. Implementing these changes can result in less energy usage.

Change Daily Habits

Simple changes to daily habits can significantly reduce electricity consumption. Also, turning off lights and unplugging devices when not in use, only running dishwashers and washing machines with full loads, and using energy-intensive appliances during off-peak times can all contribute to lower electricity usage.


To answer the question at the beginning, note that the average Ontario household uses approximately 7500 kWh of electricity per year. This consumption results from various factors, including appliance use, heating and cooling needs, water heating, and more. However, understanding how this energy helps and implementing strategies to reduce consumption can lower your household’s electricity bill and contribute to a more sustainable future.
