Will my gas fireplace still work during an Ottawa ice storm power outage for backup heat?

It depends entirely on the type of gas fireplace you have — and this is a critical distinction in Ottawa, where ice storms can leave thousands without power for days or weeks at a time.

Direct-vent gas fireplaces with electronic ignition and blower fans will NOT work during a power outage. These units require electricity to operate the spark ignition system, electronic valve controls, and the blower fan that circulates heated air into the room. The moment the power goes out, so does your fireplace. Many Ottawa homeowners discover this uncomfortable reality during the 1998 ice storm or during recent winter power outages, when they flip the switch expecting heat and get nothing. If backup heat during a grid failure is a priority for you, a gas fireplace with electronic controls is not the answer.

Vent-free (ventless) gas fireplaces are not available in Ontario, so this is not an option. The Ontario Building Code restricts vent-free gas appliances due to air quality and moisture concerns, especially in tightly sealed modern homes.

A wood stove or fireplace insert burning seasoned firewood, by contrast, will work perfectly during a power outage — wood burns regardless of whether the electrical grid is functioning. This is the single biggest advantage wood-burning appliances have over gas in Ottawa's climate. If you live in an area with a history of ice storms or extended winter power outages (which includes much of Ottawa, particularly the rural areas around Kanata, Barrhaven, and the eastern communities), a wood stove provides genuinely reliable backup heat when the grid fails. You will not be sitting in a cold dark house if you have split, seasoned firewood stacked and ready.

The Real Consideration for Ottawa

Ottawa's freeze-thaw cycle and ice storms are not theoretical risks — they are seasonal certainties. The 1998 ice storm left some neighbourhoods without power for up to three weeks. More recently, severe winter weather has knocked out power for 48 to 72 hours across parts of the city multiple times. If your gas fireplace is your primary supplemental heating system and the power goes out for an extended period, you will lose heat at the exact moment you need it most, when outdoor temperatures are at their lowest and your home's heating load is highest.

If you are seriously considering a gas fireplace for supplemental heating in Ottawa, ask yourself honestly whether you have reliable alternative heat sources if the power fails. Central forced-air furnaces also depend on electricity, so if your furnace is your only heat, a power outage during a winter storm becomes a genuine safety issue, especially for families with young children, elderly relatives, or anyone with health vulnerabilities. A backup wood stove or fireplace insert is not a luxury in Ottawa — it is a practical hedge against the climate and grid failures that Ottawa experiences regularly.

A practical middle path: Some homeowners in Ottawa install both a gas fireplace (for convenience and ambiance on normal days) and a wood stove as a separate backup system. The wood stove sits idle most of the time, but when the power goes out or the grid becomes unreliable, it becomes invaluable. Wood stove installation in Ottawa runs $4,500 to $9,500 installed depending on whether you need a new chimney or can use an existing one. Over a 20-year ownership period, that represents genuine insurance against both extended power outages and the anxiety that comes with knowing you have no backup heat if the grid fails during Ottawa's coldest weeks.
