Can I use a wood-burning fireplace during a Calgary air quality advisory?

No, you should not use a wood-burning fireplace during an air quality advisory in Calgary. The City of Calgary and Alberta Environment specifically ask residents to avoid burning wood during poor air quality events to prevent worsening conditions for everyone in the community.

During air quality advisories — which typically occur during summer wildfire season or winter temperature inversions — particulate matter (PM2.5) levels are already elevated to unhealthy levels. Wood-burning fireplaces and stoves release additional fine particulates that contribute directly to the problem. Even EPA-certified wood stoves, which burn much cleaner than traditional fireplaces, still produce measurable emissions that compound existing air quality issues.

Calgary's unique geography makes air quality advisories particularly serious. The city sits in a natural bowl between the Bow River valley and surrounding hills, which can trap pollutants during temperature inversions — especially common during winter high-pressure systems. When chinook winds aren't moving air masses through the region, smoke and particulates can linger for days. Adding wood smoke from residential fireplaces during these events creates a cumulative effect that impacts respiratory health across the entire metropolitan area.

Winter air quality advisories in Calgary often coincide with the coldest weather when homeowners most want to use their fireplaces for supplemental heating. This creates a frustrating situation, but it's precisely when wood smoke has the greatest impact — cold, still air prevents dispersion, and people spend more time indoors breathing concentrated pollutants. If you rely on a wood-burning fireplace for primary heating, consider having a backup heating plan during air quality events.

Gas fireplaces are not restricted during air quality advisories because they burn cleanly with sealed combustion systems that don't contribute to outdoor air pollution. Direct-vent gas fireplaces draw combustion air from outside and exhaust combustion products directly outside through a sealed system, making them air-quality neutral. This is one of the key advantages of gas over wood in Calgary's urban environment.

Check Environment and Climate Change Canada's Air Quality Health Index (AQHI) or the City of Calgary's website for current air quality status. The AQHI runs from 1-10+, with advisories typically issued at level 7 or higher. During these periods, vulnerable populations including children, seniors, and people with respiratory conditions should limit outdoor activities, and everyone should avoid adding to air pollution sources.

If you're considering a fireplace upgrade, this is one reason why gas fireplaces have become the dominant choice in Calgary. With ATCO Gas readily available and current rates around $3.50-$5.00 per GJ, a gas fireplace provides reliable supplemental heating without weather or air quality restrictions. You can enjoy your fireplace every day of Calgary's long winter season without worrying about contributing to community air quality problems.
