Today’s Air Quality
Air Quality Health Index (AQHI)
The AQHI is a tool that indicates the level of health risk associated with local air quality through a simple 1 to 10+ point scale – the higher the reading, the greater the health risk and the greater the need to take precautions. Find out today’s AQHI to protect your health. (Please note that for the AQHI rating for Caledon, check under Newmarket.)
