Overview

• Smoke from more than 200 wildfires in western provinces such as British Columbia and Alberta has caused hazardous air quality across urban centers from Ontario to the U.S. Midwest.
• Environment Canada and the U.S. EPA have issued air quality alerts in Ontario and Quebec cities as well as Midwestern states including Illinois, Michigan and Wisconsin.
• Health officials warn that fine particulate matter from the smoke can exacerbate respiratory and cardiovascular issues, particularly in children, seniors, pregnant individuals and those with chronic conditions.
• Residents are advised to limit outdoor activities, keep windows and doors closed, use high-efficiency air filters or portable cleaners and wear N95 respirators when venturing outside.
• Forecasts indicate smoke levels will remain elevated through the weekend with some improvement possible by Sunday as weather systems shift.
