Overview
- Canadian officials reported roughly 900–950 active wildfires, most uncontrolled, that have sent dense smoke into major U.S. and Canadian cities and degraded air quality across the Northeast and Midwest.
- President Trump posted on his Truth Social account that the United States will add the 'costs of this pollution' to existing tariffs and said he would call Canadian prime minister Mark Carney to press for action.
- Several Republican lawmakers echoed the president and signaled possible sanctions or legislative measures targeting Canada, framing the issue as a failure of Canadian forest management.
- Canada’s disaster minister said Ottawa and Washington are in constant contact and noted billions invested since 2020 in forest sustainability and fire prevention, while experts point to climate change as a key driver of larger, more frequent fires.
- Air-quality monitors placed New York and Toronto among the worst in the world at times, prompting public-health warnings, event cancellations and concern for fans and vulnerable residents even as shifting weather could quickly change local smoke levels.
