‘Limit time outside,’ ECCC issues air quality alert across region

On Wednesday, a ‘yellow’ heat warning and an ‘orange’ air quality warning were issued for many of the municipalities across the region.

As wildfires burn through much of northern Ontario, the effects can be seen and felt across Simcoe County and Muskoka. Many residents awoke to strong haze on Wednesday morning, following the hottest day of the year so far. On Wednesday, a ‘yellow’ heat warning and an ‘orange’ air quality warning were issued for many of the municipalities across the region.

Environment and Climate Change Canada estimates a daytime high of up to 36 C and a low of 20 C. “Limit time outdoors, reschedule or cancel outdoor sports, activities and events,” the weather agency says as part of its air quality warning. ECCC urges pregnant women, the elderly, infants, young children and those with existing illness or chronic health conditions to “avoid strenuous activities outdoors.” “During heavy smoke conditions, everyone’s health is at risk regardless of their age or health status,” the organization says.

“A well-constructed, well-fitting and properly worn respirator type mask, such as a NIOSH-certified N95 or equivalent respirator can reduce your exposure to the fine particles in the smoke,” ECCC says. “Even though exposure may be reduced, there can still be risks to health,” the organization adds. Environment Canada says residents may experience eye, nose and throat irritation, headaches or a mild cough due to the air quality.

More serious but less common symptoms include wheezing, chest pains or severe cough. According to the agency, conditions may improve by Friday.
