Environment and Climate Change Canada has issued a Yellow Air Quality Warning for Wednesday, July 15, as wildfire smoke continues to affect parts of southwestern Ontario, including London and Middlesex County.
The smoke is expected to cause poor air quality and reduced visibility across much of southern Ontario throughout the day, with conditions potentially lasting for several more days.
A Yellow Air Quality Warning means wildfire smoke may pose an increased health risk, particularly for vulnerable groups such as older adults, young children, pregnant people, and those with heart or lung conditions.
Exposure to wildfire smoke can cause symptoms including irritated eyes, a runny nose, sore throat, headaches and coughing. More serious symptoms, such as wheezing, chest pain or a severe cough, are less common but may occur.
Residents experiencing symptoms are encouraged to limit the amount of time they spend outdoors and monitor local air quality conditions using the Air Quality Health Index (AQHI). Officials also recommend checking in on family, friends and neighbours who may be more susceptible to poor air quality.
Health officials are advising residents to reduce strenuous outdoor activities, especially if they have asthma, heart disease or other respiratory conditions. Anyone experiencing shortness of breath, wheezing, severe coughing, dizziness or chest pain should move indoors and seek medical attention if symptoms persist.
People without access to well-ventilated indoor spaces are encouraged to spend time in public buildings such as libraries, shopping malls or community centres. Staying hydrated, listening to your body and taking breaks from outdoor activities can also help reduce the effects of smoke exposure.
Officials also remind residents to pay attention to their mental well-being, noting that feeling anxious or isolated during prolonged wildfire smoke events is a normal response.
