On July 17th local time, U.S. President Donald Trump posted on his own social media platform 'Real Social', accusing Canada of poor forest management, which caused wildfire pollution to spread to the United States, affecting air quality in the country.
"We believe Canada should be responsible for their failure to adequately protect forests..." Trump wrote, "The United States is being besieged by dirty, polluted, and unhealthy air."
He stated that such situations occur annually, causing losses of “hundreds of millions of dollars” to the United States, which is “completely unacceptable”.
He also claimed he would contact Canada's Prime Minister Justin Trudeau that day and threaten to add the U.S. losses to Canadian tariffs.
In 2025, shortly after taking office, Trump imposed tariffs on several major imported goods from Canada.
Canada has not responded to this matter yet. On the 16th, Kannei said that the United States can take more measures to address climate change, as climate change is causing global temperatures to rise and extreme weather conditions to intensify.

According to Reuters, in recent days, thick smoke from hundreds of wildfires in Canada has covered large areas of the United States, from the Midwest to the Northeast. This has prompted authorities to warn residents to stay indoors. Climate experts have noted that rising temperatures in recent years have made forests drier and wildfires more frequent. Canada has one of the largest forests in the world.
On July 19 local time, the final match of the US-Mexico-Mean World Cup will be held at the New Jersey Stadium in New York, USA. Donald Trump will attend to watch the event.
According to people familiar with the matter, although the smoke from wildfires in Canada has deteriorated the air quality in New York, FIFA has no plans to move the final to another location.
