Alberta Premier Rachel Notley says the wildfire has destroyed about 1,600 structures in Fort McMurray, which is in Canada's oil sands region. No major oil sands facilities are in the fire's path, though two Royal Dutch Shell mines are closing, and a Suncor Energy facility is reducing crude production. The fire is threatening the Alberta Highway 63 bridge across the Athabasca River, the sole route south. The Canadian Red Cross is encouraging people to donate funds rather than clothing.
