The wildfire in Alberta, Canada has become the worst in the province's history. Financial institutions believe the fire could become the costliest natural disaster in Canadian history in terms of economic losses. As of May 9, the raging wildfire had doubled in size to 200,000 hectares - three times the size of Toronto, Canada's largest city.

        On May 1 local time, a wildfire was reported in Alberta, Canada. The local government immediately took firefighting measures, but after May 3 the fire suddenly intensified, engulfing Fort McMurray and forcing the emergency evacuation of nearly 90,000 people. At present, governments at all levels in Canada are fully engaged in relief efforts, with more than 1,100 professional firefighters battling the blaze with the support of firefighting aircraft.

        The fire remains out of control. Fire officials believe that only cooler air temperatures and rainfall can ease the disaster. The hard-hit Fort McMurray area has been severely damaged, and residents will be unable to return home in the short term. Beginning on May 6, authorities started relocating more than 25,000 evacuees from the north of the city to other cities in the south, and Alberta has declared a province-wide state of emergency to respond to the disaster with full force.
