Air quality alerts have been issued across Canada and northern USA as smoke from widespread wildfires continues to degrade air conditions, prompting urgent health warnings. Environment Canada has warned residents, especially in Ontario and Toronto (where air quality recently ranked among the worst globally), to limit outdoor exposure. Similar alerts have been issued in US cities like Chicago, where unhealthy ozone levels and residual smoke from Canadian fires are posing additional concerns. Wildfires raging across Manitoba, Saskatchewan, and northern Ontario have forced tens of thousands to evacuate, with emergency responders working to assess the rapidly changing situation. Also, political tensions emerged after some Congress members said Canada’s wildfires were ‘making it difficult for Americans to enjoy their summer’. Scientists attribute the increasing intensity and frequency of wildfires to climate change; Canada is believed to be warming at twice the global rate.
