Southern wildfires might affect northern air quality, Health Department says

Wildfires burning in the Prairie provinces might be affecting air quality across Nunavut and people should take precautions, Health Department officials say.

“Depending on wind and weather conditions, wildfire smoke can travel thousands of kilometres which means that even without active fires within the territory, air quality can still be impacted,” said Chelsea Halvorson, a spokesperson for the Department of Health.

“This is a common occurrence during the summer months, and Nunavummiut are encouraged to remain aware of local conditions and take precautions as needed.”

She said the air quality index provided by the federal Environment and Natural Resources Department suggests the fires’ impact on air quality in Iqaluit is low risk and it’s safe for outdoor activities.

“However, due to limited formal air quality monitoring across Nunavut, localized conditions may vary,” she said. “Communities may experience smoke and reduced air quality even if there are no official (air quality index) readings in place.”

That makes it important for Nunavummiut to remain aware of air quality indicators, such as visible smoke or the smell of smoke, in their communities.

If wildfire smoke is detected in a community, residents can reduce exposure by avoiding outdoor exercise and strenuous activities, and staying inside with windows and doors closed.

They can also use fans or air purifiers, avoid burning candles or anything that can add to indoor air pollution, and limit the use of exhaust fans when not cooking.

Winnipeg remained under an air quality advisory Friday, meaning smoke was causing or expected to cause poor air quality and reduced visibility.

People most likely to be affected by wildfire smoke include those aged 65 and older, pregnant women, infants and young children, people with an existing illness or chronic health condition, and those who work outdoors.

They should avoid strenuous activities outside and seek medical attention if experiencing symptoms, according to an advisory posted to the Department of Environment and Natural Resources website.

Under Winnipeg’s current heavy smoke conditions, everyone’s health is at risk regardless of their age or health status.

Saskatchewan also has air quality advisories in effect due to five forest fires and grass fires that have yet to be contained. Alberta currently has three wildfires that pose a threat to public safety, communities or critical infrastructure.
