Extreme Fire Danger Returns to Banff National Park as B.C. Wildfire Smoke Moves Into Bow Valley

An extreme wildfire danger rating has returned to Banff National Park as smoke from an active wildfire in British Columbia drifts into the Bow Valley, reducing air quality and underscoring the heightened fire risk across the region.

Parks Canada has raised the park's fire danger to Extreme, its highest rating, meaning any new fire could spread rapidly under current conditions.

The elevated fire danger comes as Environment Canada issued a Yellow Air Quality Warning for Banff National Park on Thursday afternoon, meaning wildfire smoke is expected to create moderate health risks and periods of poor air quality through the weekend.

The smoke is originating from the Brunswick Creek and Ainslie Creek wildfires near Highway 1 south of Lytton, B.C., where the Fraser Valley Regional District has issued evacuation orders for parts of North Bend and a travel advisory remains in effect for sections of the Trans-Canada Highway.

No active wildfires were listed in Banff National Park as of Thursday afternoon, although Parks Canada says it is actively monitoring the park for new starts and is prepared to respond quickly if they occur.

The combination of hot, dry conditions and smoky skies serves as a reminder that wildfire season remains active across Western Canada, even when flames are hundreds of kilometres away.

Smoke Expected Through the Weekend

Environment Canada says wildfire smoke is causing periods of poor air quality and reduced visibility, with conditions expected to fluctuate from hour to hour depending on changing winds.

Health officials advise residents and visitors to reduce or reschedule strenuous outdoor activities when smoke becomes heavy, particularly children, older adults, pregnant people, those with chronic health conditions and anyone who works outdoors.

Common symptoms from smoke exposure include irritated eyes, nose and throat, headaches and coughing. People experiencing more serious symptoms such as wheezing, chest pain or severe coughing are advised to seek medical attention.

Officials also recommend keeping windows and doors closed when possible, using high-quality air filtration indoors and wearing a properly fitted N95 respirator if spending extended periods outside in smoky conditions.

Campfires Limited to Designated Fire Pits

With fire danger now rated as extreme, Parks Canada is reminding visitors that campfires are only permitted in designated metal fire rings, fire boxes or cooking shelters provided by the agency.

Building campfires in makeshift rock rings or on open ground is prohibited throughout the national park.

Visitors are also encouraged to report any wildfires, illegal campfires or suspicious smoke immediately to Banff Dispatch at 403-762-1470.

Although no fire ban has been announced for Banff National Park as of Thursday afternoon, officials say the extreme fire danger means everyone has an important role to play in preventing human-caused wildfires.

Even a single escaped campfire or discarded cigarette can ignite dry vegetation under current conditions, creating the potential for a fast-moving wildfire.
