An air quality warning is in effect for much of northwestern Ontario, with officials cautioning that while conditions may temporarily improve, pollution levels could rise again by evening. A special air quality statement was also issued for most of northeastern Ontario, where westerly winds are carrying smoke from active wildfires. “Westerly winds will bring smoke from forest fires over northern Ontario to the area, causing the air quality to deteriorate,” the statement read. “The poor air quality will persist through tonight and possibly Monday before improving.” Health officials warned that vulnerable groups – including seniors, pregnant individuals, young children, people with chronic illnesses, and outdoor workers – should avoid strenuous activities outside. Common symptoms from smoke exposure include eye, nose, and throat irritation, headaches, and mild coughs, while more severe reactions may involve wheezing, chest pain, or difficulty breathing. Residents are urged to seek medical help if symptoms worsen.
