Quick answer

What does Cities with cleanest air in Canada show?

Halifax, Canada has the lowest pm2.5 — annual mean of the 30 cities compared: 1.9 µg/m³ (Official ECCC/NAPS 2024 annual daily-mean station observations, reproducibly aggregated as an arithmetic mean for eligible stations within 25 km of the target city coordinate. This is a derived place observation, not an asserted municipal monitor aggregate., 2024).

How this list is built

Every row is a published pm2.5 — annual mean observation measured in µg/m³, ranked lowest first. The values were observed in 2024. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.

  • Compare the displayed value, unit, source date and geographic grain together.
  • A city label does not change a regional observation into a city measurement.
