The explosive 2025 wildfire season in Central Canada reflects an increasing trend of large-scale burning driven by climate change. This analysis quantifies the direct and transboundary impacts of the fires from mid-May to early June 2025. By early June, the fires had burned over 2.7 million hectares and forced over 33,000 evacuations. Using satellite and population data, we assessed the human consequences, revealing a significant international smoke event that exposed over 117 million people in the United States to heavy smoke on a single day. These fires, exacerbated by anomalously warm and dry conditions, underscore the urgent need for a paradigm shift toward heightened community preparedness, enhanced societal resilience, proactive prevention, and robust international cooperation to manage the cascading cross-border health and safety impacts of wildfires.
