Metro Vancouver’s air quality this week is worse than what people are experiencing in megacities like Shanghai or New Delhi.
According to IQAir, a Swiss-designed air quality information system, the air in the region is currently among the hardest to breathe in the world.
It's due to smoke that’s continued to waft over the border from wildfires in Washington State.
For worst air quality and pollution, Metro Vancouver ranked fifth worldwide. New Delhi, India's capital, was listed as seventh. Shanghai, China was 28th.

A Metro Vancouver air quality advisory that was first issued on Tuesday, Sept. 8 continued to be in effect Friday.
According to Metro Vancouver environmental monitoring expert, Ken Reid, fine particulate matter in the air has increased "dramatically."
As of Friday, the region had equal to 100 micrograms of fine particulate matter (PM 2.5) per cubic metres in its air – due to the smoke.
"A hot, sunny day in Vancouver would only see upwards of 15 micrograms in the air," Reid explained.
Air quality in the region is predicted to worsen into the weekend, said Reid.

"Wildfire smoke from fires in Washington and Oregon has moved northward into the region this morning and forecast to impact air quality through the weekend as a large mass of smoke moves through," explained a Sept. 11 news release from the regional government.
Exposure to PM 2.5 is particularly a concern for people with underlying conditions, respiratory infections, pregnant women, infants, children, and older adults, Reid added.
"It is unclear whether the matter will remain higher up or stay at ground level," he said, which poses a health risk for those breathing them in.
The expert suggested people reduce their time spent outdoors and purchase a high-efficiency particulate air (HEPA) purifier if possible.
