Toronto is experiencing one of the worst air quality levels globally today as thick smoke from wildfires drifts into the region, prompting serious health warnings.
Smoke from wildfires has led to the issuance of a special air quality statement covering the Greater Toronto Area, much of southern Ontario, five other provinces, and one territory.
With wildfires intensifying across the country, the air quality has worsened significantly. So far this month, 15 new out-of-control wildfires have been reported in northern Ontario and Western Canada. Smoke from these fires has now made its way south into Ontario.
Toronto’s Air Quality Health Index (AQHI) is expected to peak at 7 out of 10 — a level classified as high risk. Earlier in the day, the city was ranked as having the second-worst air quality in the world, based on international monitoring data.
“Only a few see the flames, but millions smell the smoke,” one official noted, emphasizing how widespread the impact has become.
Residents in affected areas are being strongly advised to limit outdoor activities, especially during the morning and early afternoon when smoke levels are expected to rise before easing by evening.
Health authorities warn that increased smoke levels can pose health risks. Common symptoms include:
- Mild irritation of the eyes, nose, and throat
- Headaches or a mild cough
More severe symptoms — though less common — may include wheezing, chest pain, or a persistent, severe cough.
Vulnerable groups, including people with pre-existing respiratory conditions, pregnant individuals, seniors, and young children, are especially at risk.
While air quality levels may fluctuate over the weekend, smoky conditions are likely to persist into early next week.
The arrival of warm weather — long-awaited by many — has unfortunately come with hazy skies and poor air, rather than clear summer days. As one expert put it, “It took so long for the summer-like weather to come, and when it did, it came not with blue skies, but with smelly, smoky air.”
Authorities continue to monitor the situation closely and urge residents to stay informed and prioritize their health during this period of deteriorating air quality.
