Risk of wildfire smoke in Ottawa low — for now: Environment Canada

Smoke from wildfires in Western Canada will soon be drifting high overhead, but it poses no health risk in Eastern Ontario, says Environment Canada.

“Taking a look at our guidance and the weather patterns this week and the way things are panning out, it doesn’t look like Eastern Ontario needs to be concerned about its air quality at this time,” Trudy Kidd, a warning preparedness meteorologist with Environment Canada, said Monday.

“At best, people might see some haze in the skies in the coming days as the forest fire smoke makes its way through and disperses aloft, but from what we can tell at this time, the particulate matter — and that’s what’s of concern when it comes to forest fires — we’re expecting it to stay aloft,” she said.

Air Pollution Is Really Dangerous, Even More New Evidence Shows

PM2.5 particles are tiny enough to enter the bloodstream and lodge in the lungs, where they contribute to respiratory problems such as asthma. They also can prompt heart attacks and strokes. And they have been linked to diabetes, obesity and dementia and may exacerbate COVID.

Wildfire smoke may have contributed to thousands of extra COVID-19 cases and deaths in western U.S. in 2020

Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health.
