The smoke from the Canada wildfires 2026 is once again drifting across large parts of Canada and the United States, triggering air quality alerts, prompting evacuations, and raising fresh concerns among health experts. While the flames remain concentrated in several Canadian provinces, the impact is being felt hundreds of kilometres away as thick smoke blankets cities from Minnesota and Ontario to New York and parts of the US Northeast.
Health experts warn that wildfire smoke is more than just an inconvenience. It contains tiny particles and toxic gases that can affect the lungs, heart and overall health, particularly among children, older adults, pregnant women and people with pre-existing medical conditions.
