Today’s Air Quality
Air Quality Health Index (AQHI)
The AQHI is a national health-based index to help individuals protect their health and the health of people in their care. The AQHI uses a simple 10-point scale to indicate the level of health risk associated with local air quality – 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.)
