About 3.8 million hectares (9.4 million acres) have already
burned, roughly 15 times the 10-year average, according to
federal Minister of Emergency Preparedness Bill Blair. Warm, dry
conditions were expected to persist in the months ahead.
Although wildfires are common in Canada, it is unusual for
blazes to be burning simultaneously in the east and west,
stretching firefighting resources and forcing the Canadian
government to send in the military to help. Hundreds of U.S.
firefighters arrived in Canada to help and more were on their
way.
Prime Minister Justin Trudeau blamed climate change. "These
fires are affecting everyday routines, lives and livelihoods,
and our air quality," Trudeau said on Twitter.
Some of the worst fires have sprung up in the eastern province
of Quebec, and more than 11,000 people had to evacuate their
homes in Quebec.
Wildfire season started unseasonably early in Alberta last month
and burned a record area, and Nova Scotia continues to battle
its largest-ever blaze,
In parts of the Pacific province of British Columbia, which is
facing the second-biggest wildfire on record, temperatures were
forecast to hit 33 Celsius (91 Fahrenheit) on Thursday, before
thunderstorms and heavy rains arrive on Friday.
Rob Schweitzer, executive director of BC Wildfire, said
lightning strikes could spark more blazes in tinder-dry forests
and the outcome would depend on how much precipitation comes
with the storms.
"When you get 150 or 200 strikes in one day from lightning
coming through the province, it's impossible to have enough
resources to suppress them all," he said.
Wildfires have eased in Alberta, the center of Canada's oil and
gas industry, but more than 3,000 people remain under evacuation
orders and heat warnings are in effect in the south of the
province.
Smoke-forecasting website BlueSky Canada showed wildfire smoke
spreading across much of the country on Thursday. The smoke is
set to intensify in Ottawa, Toronto, Cleveland and Pittsburgh
and remain thick in other cities along the east coast of the
United States, including New York.
