Air Quality Health Index

AIR QUALITY HEALTH INDEX strategy performance measure

Data from the Lower Fraser Valley Air Quality Monitoring Network are used by Environment and Climate Change Canada to calculate the Air Quality Health Index (AQHI). The AQHI provides information about the relative risks to human health from exposure to ground-level ozone, fine particulate matter and nitrogen dioxide across Canada. Further information is available about the AQHI on Environment and Climate Change Canada’s website.

Metro 2040 vision

Metro 2040 encourages consideration of overall health implications in new development. Air quality is one of many determinants of overall health.

Percent of Time in the AQHI Low Health Risk Category

Changes are made to the AQHI formula as updated information about health risk is available. In 2016, adjustments were made to incorporate wildfire smoke health risk information.

In 2018, air quality was in the low health risk category over 94% of the time. Wildfire smoke from outside the region resulted in a smaller proportion of the year being in the low risk category in 2018.
