US President Trump posted on social media on the 17th local time accusing Canada of poor forest maintenance, saying that forest fires in Canada affect US air quality. Similar situations occur every year, causing “billions of dollars” in losses to the US. He said he would call the Canadian Prime Minister about this on the same day, and threatened that the US losses must be added to the tariffs paid by Canada.
