Toronto air ranked among world's worst as wildfire smoke billows south

Toronto edged out New Delhi and the Democratic Republic of Congo's capital Kinshasa as wildfire smoke turned the skies a hazy yellowish-grey in Canada's largest city. While this year's wildfire season has been fairly muted compared to the devastation caused in recent years, there are more than 800 active fires nationwide.
