On the 17th, US President Trump posted on social media, criticizing Canada for poor forest management.
He pointed out that Canadian forest wildfires are affecting US air quality, and that similar situations occur every year, causing the US billions of dollars in losses.
He stated that he would call the Canadian Prime Minister about this matter that day, and threatened that the losses suffered by the US must be added to the tariffs that Canada pays.
The EU Copernicus Atmosphere Monitoring Service stated on the 17th that the ongoing wildfires in Canada are producing large amounts of smoke, which is worsening air quality in many areas of Canada and the northeastern United States.
