What is the best fire pit fuel type for Ottawa's long winters?

Ottawa homeowners who want to use a fire pit through the colder months — and with winter stretching from November well into April here — need a fuel source that performs reliably at extreme low temperatures, ignites quickly when you want heat, and shuts off cleanly when you head inside. Natural gas is the strongest all-around choice for winter fire pit use in Ottawa, followed closely by propane, with wood burning presenting the most complications in cold-weather conditions.

Natural gas delivers consistent BTU output regardless of ambient temperature. At -25°C or -30°C, a natural gas fire pit lights instantly and burns at full capacity because the gas arrives through your home's supply line at steady pressure. There are no tanks to manage, no fuel to store outdoors, and no degraded performance in cold weather. For Ottawa homeowners who already have a natural gas connection — and most homes in the urban core and suburbs do — running a dedicated line to a patio fire pit is a straightforward project. The ongoing fuel cost is also significantly lower than propane, which matters when you are running the fire pit regularly through a six-month cold season.

Propane is the best alternative if natural gas is not available at your property, which is common in parts of rural Ottawa, Kanata's outer subdivisions, and some areas of Orleans. However, propane has a notable cold-weather limitation: standard 20 lb portable tanks lose pressure as the liquid propane inside gets colder, and below approximately -25°C to -30°C the vaporization rate drops to the point where a small tank may not deliver enough gas to sustain a full flame. The workaround is using a larger bulk tank (100 lb or more) which maintains better pressure at low temperatures due to the greater volume of liquid. If you plan to use a propane fire pit in Ottawa's deep winter, sizing up the tank is not optional — it is a functional necessity.

Wood-burning fire pits offer the most atmospheric experience but are the least practical for Ottawa's winter use. Wet or frozen wood is difficult to ignite, hardwoods like oak and maple take much longer to reach full combustion in frigid air, and the smoke produced during a slow-starting cold burn can be substantial. Ottawa Fire Services bylaws also restrict open burning during certain conditions, and the smoke can draw complaints from neighbours — something less likely to happen in July but very possible in January when windows may be closed but furnace air intakes pull in outdoor air. You also cannot simply turn off a wood fire; it needs to burn down completely, which means tending it long after you have gone inside.

Many Ottawa homeowners settle on a natural gas fire pit for regular winter use and keep a separate portable wood-burning pit for summer gatherings when lighting conditions are easier and the experience of a real wood fire is most enjoyable.
