  Using pm 2.5 is only one way to measure overall air quality. The CTV article should have linked to their site, which hosts the original blog post and explains their methodology
  https://housefresh.com/secondhand-smoke-world-map/

  The basically scrapped average fine particulate data from this site (https://aqicn.org/), and converted it “cigarettes per year”. It does strike me as a bit of pseudo science hiding their real goal which is to create marketing hype for air purifiers ( it also offers lots of reviews).

  So many review sites turn out to be sponsored by the companies…deck paint is one very well known example. Not sure yet if house fresh falls into that category.

  Remember a few years ago when our air pollution monitors went through the roof, and it turned out it was because of a nearby pizza oven? I’ve been skeptical ever since.

  According to https://aqicn.org/city/montreal/ today is a good air quality day.
  I am a fan of the wood-stove and wood fireplace ban (technically, disallowing non-epa-approved wood stoves) Montreal enacted a few years ago. Air quality is much better.
  There is a NFB film about Rick Leckner doing traffic reporting from a helicopter and he says at one point not to fly too low bc the air is not breathable (days of every building had a garbage incinerator in the building & low-quality bunker-oil furnaces)

  Leckner must be ancient. He was quoted in the media just this week, but I remember him doing helicopter traffic reports when I was a kid.
