Climatologist David Phillips details worsening conditions amid massive Ontario wildfires forcing evacuations.

Over 148 active wildfires are burning across Ontario, with numerous fires remaining out of control due to extreme heat and dry conditions, forcing mandatory evacuations in northwestern Ontario. Officials have issued warnings as thick smoke degrades air quality across much of southern Ontario. Climatologist David Phillips explained that the poor air quality results from a rare combination of weather, including a heat dome that trapped smoke close to the surface. Evacuation orders remain in effect for multiple communities, including Armstrong and Whitesand First Nation, as fire crews battle rapidly changing conditions. Health officials urge residents to remain indoors when air quality is poor, advising that proper masks, such as N95 respirators, may help filter some particles for those who must go outside. Authorities across the province are urging residents to remain prepared for potential further evacuations. The focus remains on protecting communities and critical infrastructure as the fire season shows no signs of immediate abatement.
