The largest city in Canada Toronto is included in the list of cities of the world with the most polluted air. This is evidenced by the data of the IQAIR air quality control.
According to IQAIR, the quality of the air in Toronto worsened greatly due to the ongoing forest fires.
In turn, the Ministry of Environment of Canada reported that the smoke from fires reached other cities of Ontario, including Toronto and Hamilton, which also led to a deterioration in air quality.
Toronto today closes the five cities with the most polluted air in the world.
