NYC sees world's worst air quality, thanks to Canada wildfires

Canada's Environment Department on Tuesday issued its strongest warning for the capital city of Ottawa, deeming its air quality a "very high risk" to people's health, reported the BBC. This came as the country has been witnessing raging wildfires in the major cities of Ontario and Quebec provinces. Notably, Canada's wildfire smoke has also become "unhealthy" for the United States (US).
