Prime Minister Mark Carney said on July 18 Canada is facing one of its most
severe wildfire seasons amid extreme heat and record drought and the government
has launched an all‑hands mobilization. More than 5,300 firefighters and nearly
300 aircraft have been deployed; the interdepartmental wildland fire centre
reported 3,815 fires YTD and over 2.9 mln ha burned. Rising temperatures and
more frequent heatwaves linked to global climate change have heightened fire
risk, and wildfire smoke has degraded air quality across Canada and parts of the
US Northeast.
