Wildfires have forced an evacuation of Yellowknife, the capital of Canada’s Northwest Territories.
Officials with the territorial government told residents in the highest risk areas to evacuate immediately. Other residents have until 12 p.m. local time on Friday to leave the city of about 20,000.
Depending on smoke conditions, those leaving by car will be escorted through the active fire zone, officials said. Residents who can’t leave by road are being asked to register for evacuation flights.
