Natural gas is the most commonly used gas in residential applications in Canada for several reasons. It is widely available, cost-effective, and provides an efficient source of energy for heating, cooking, and other household needs. Canadian infrastructure supports the distribution of natural gas through pipelines, making it accessible to a large portion of the population.

In addition to its availability, natural gas has a relatively lower carbon footprint compared to other sources of energy such as propane and heating oil, making it an environmentally friendly choice. The energy content of natural gas is high, which allows it to effectively meet the heating demands of residential spaces.

Propane, while also used in some rural areas and for specific applications, is less common compared to natural gas for general residential use. Butane and biogas are utilized in more specialized contexts and do not have the widespread applications that natural gas enjoys in the home. Biogas, for instance, is still a developing technology and is primarily used in certain regions or specific applications such as digesters.
