The air quality in Vancouver is being affected by wildfires in the Okanagan and Kootenay region but the source of the problem is not clear, according to the Vancouver Foundation.
From June 17 until October, Vancouver’s air quality is rated as moderate or worse on six of seven days, according to Environment Canada’s Air Quality Index, though the index is seasonal and the rating is based on an average of the last three days rather than one or two.

The index uses six air quality levels with air quality rated as excellent being the best.

The index rates air quality as moderate or worse on five days with air quality rated as excellent on two of those days.

The air pollution index is based on a comparison of outdoor air quality in the region to outdoor air quality in three other locations surrounding Vancouver: the Calgary Region, Edmonton, and Kelowna.
The Air Quality Index is a measure of air quality and is calculated using the data collected from monitors located throughout the greater Metro Vancouver region and nearby cities as of 6:00 p.m. on the day after each day’s reporting.

The Air Quality Index uses an “air quality” rather than “pollution” to describe the air quality, according to the National Collaboratory for Air Quality Research.

The Air Quality Index is updated every five minutes and recorded on the “atmospheric quality index,” which is based on measurements of the concentration of seven criteria pollutants: ozone, carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide and lead.
