Canada vs Mexico Air quality index (AQI) and deforestation
Canada has cleaner air than Mexico right now: its cities average AQI 25 against 69.
At ground stations alone, which measure rather than estimate, the averages are Canada 24 (55 cities) and Mexico 91 (46 cities). Canada has lost more forest since 2001. Canada has more tree cover in its cities.
Updated . Lower is better on the US EPA index: 0–50 is Good, above 300 is Hazardous. Measured by Airleaf.

Deforestation · 2001–2025
Which country has lost more forest, Canada or Mexico?
Canada has lost more: about 65.6 million ha of forest from 2001 to 2025, against 5.46 million ha in Mexico, or 12 times as much. 899,000 ha of Canada's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2023, with 8.38 million ha lost.
Worst year: 2024, with 332,000 ha lost.

Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 59 in Canada and 114 in Mexico, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Mexico rests on 114 cities against 59, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Canada vs Mexico: your questions answered
Is Canada cleaner than Mexico?
On air quality, yes, right now: Canada's cities average AQI 25 against 69 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather. At ground stations alone, which measure rather than estimate, the averages are Canada 24 (55 cities) and Mexico 91 (46 cities).
Which country has lost more forest, Canada or Mexico?
Canada has lost more: about 65.6 million ha of forest from 2001 to 2025, against 5.46 million ha in Mexico, or 12 times as much. 899,000 ha of Canada's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, Canada or Mexico?
Canada does: its measured cities average 33.1% tree cover against 14.6%, a gap of 18.5 percentage points.
How many cities are the Canada and Mexico figures based on?
59 measured cities in Canada and 114 in Mexico. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Why are there two air quality averages for each country?
The first covers every measured city, using a ground station where one is close and a model estimate everywhere else. The second counts only cities with a current station reading, which is measured rather than estimated but covers fewer places. Airleaf's world rankings use the station figures only.
Does this cover the whole of Canada and Mexico?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
