On Wednesday, Toronto woke to an orange‑tinged sky caused by distant wildfires. Smoke from multiple fires across Ontario drifted eastward over the city. Air quality monitors recorded readings that

ranked among the worst globally. The deteriorated conditions prompted health advisories for residents. The same smoke plume traveled across the border into the U.S. Northeast. New York City

reported visible haze and elevated particulate levels. Officials in both countries warned of potential respiratory impacts. Emergency services prepared to support vulnerable populations as the

haze persisted. Meteorologists expect the smoke to linger until wind patterns shift. The event underscores the transboundary nature of wildfire pollution.
