Intro

Evacuees are arriving in Hay River, N.W.T. from multiple communities. Residents of Fort Providence are watching and waiting as a fast-moving wildfire bears down on their homes. The smoke is spreading to other parts of Canada.

And: In Newfoundland and Labrador, kids and families are trying to navigate the first days of school under the shadow of one of the province’s worst wildfire seasons — with classrooms destroyed and smoke in the air.

Also: Drought in Canada could be leaving Monarch butterflies hungry. New research shows they can’t get the nectar they need to fuel their migrations.

Plus: China hosts a summit with an eye to reorient the global trade map, earthquake recovery in Afghanistan, the possibilities of “open skies” in Canada, and more.
