Canada wildfire threat eases, but oil drilling continues with summer around the corner

Canada is just entering a new fire season after last year’s record number of wildfires sent choking smoke across parts of the U.S. and forced more than 235,000 Canadians to evacuate their communities.

The threat from a wildfire near Canada’s oil sands hub of Fort McMurray, Alberta, appeared to be easing on Wednesday, a day after it forced thousands of residents to evacuate and stirred memories of a damaging blaze nearly a decade earlier.
