Smoke from over 800 wildfires burning in Canada has drifted across North America, prompting air quality alerts in numerous cities. The affected areas include major urban centers such as Toronto and New York, as well as portions of the US Midwest and Great Lakes region. The widespread smoke results from ongoing fire activity across Canadian provinces. This atmospheric condition has led to hazy skies and health advisories for vulnerable populations in the impacted areas.
