Forest fire smoke in Canada is suffocating Toronto and threatening U.S. cities

The smoke clouds produced by forest fires in Canada covered the skies of Toronto, causing air quality to be classified as "Very High Risk," with expectations of hazardous weather conditions continuing until the end of the week. These fires, concentrated in Ontario, Manitoba, and Saskatchewan, have resulted in significant air pollution, contributing to the deterioration of residents' health. The city recorded the highest pollution levels in the world according to specialized air quality companies, with warnings about long-term impacts due to climate change. In the United States, the smoke caused a decline in air quality in New York, prompting authorities to issue warnings to residents, especially those with health issues. The pollution is expected to persist until the end of the week, as smoke from the Canadian fires—recurring every summer—continues to spread and affect large areas.
