Toronto's skyline was shrouded in an unusual orange haze on Wednesday, July 15, 2026, as dense smoke from ongoing wildfires in northwestern Ontario drifted south. The city experienced some of the worst air quality globally, according to IQAir, a real-time air quality tracking company. Environment Canada issued an air quality warning, classifying the risk as "very high," urging residents to limit outdoor activities.
The smoke has led to numerous cancellations and closures across the Greater Toronto Area, including city-run outdoor pools and the FIFA Fan Festival. Health advisories highlight potential symptoms such as eye, nose, and throat irritation, headaches, and coughs, with more severe respiratory issues possible for vulnerable populations, including seniors, young children, pregnant individuals, and those with pre-existing health conditions. Experts suggest that such conditions, exacerbated by heat waves, may become more frequent in the coming decades.
While a heat warning for Toronto was lifted on Wednesday afternoon, the air quality alert is expected to persist, with some improvement anticipated by Friday morning. Residents are advised to stay indoors, keep windows and doors closed, and use high-quality air filters. Health officials recommend wearing N95 masks if venturing outdoors is unavoidable. The wildfires in northwestern Ontario continue to burn, with many fires not yet under control, contributing to the persistent smoky conditions.
