Canadian wildfires

Before smoke from Canadian wildfires drifted into northeastern states this spring and summer, about half of New York counties were equipped with air quality sensors.

Smoke from Canadian wildfires poured into the U.S. East Coast and Midwest over the past week covering the capitals of both nations in an unhealthy haze, holding up flights at major airports, postponing baseball games - Major League and little league - and prompting people to fish out pandemic era facemasks.

As authorities on the eastern seaboard of the U.S. provide air quality alerts, Canadian officials continue to fight numerous wildfires that are the cause of the particulate material.
