Poor air quality warnings remain in effect for the Greater Toronto Area due to wildfire smoke for the fourth consecutive day. Conditions in southern Ontario are impacted by smoke, but a shift to clean air from the east should lead to improvements, with the worst expected to pass by midweek. Toronto's air quality has improved, dropping in global rankings. Vulnerable populations are advised to limit outdoor activity, as symptoms from poor air quality may include respiratory issues and discomfort. Bad air conditions are likely to persist until anticipated rain later in the week.
"With clean air coming in from the east, air quality is expected to improve through Tuesday with 'the worst of it' gone by Wednesday," says Lucas Alexopoulos.
"We can expect some reduced air quality from forest fire smoke as we've seen the past couple of days. However, it shouldn't be as severe as it has been," he says.
"People with vulnerabilities, such as respiratory conditions, are advised to reduce their time outdoors and follow guidelines set by local authorities," says Alexopoulos.
"Symptoms can include eye, nose, and throat irritation, headaches, and a mild cough. While it's not as common, Environment Canada says wheezing, chest pains or a severe cough are also potential symptoms."
