THUNDER BAY — Tuesday was the busiest day of what has already been a hectic few weeks for forest firefighters in Northwestern Ontario. The Aviation, Forest Fires and Emergency Services agency reported 70 new fires as of 8:37 p.m. EDT. That brought the number of active fires in the Northwest Region alone to 165, including 84 that are not under control. Twenty of the new fires were in the Red Lake district, and 24 were in the Sioux Lookout district. With no sign of imminent relief from fire threats, residents of two more Northwestern Ontario First Nations are to be flown to safety in other communities starting Wednesday. The Ministry of the Solicitor General says partial evacuations are planned for both North Spirit Lake and Cat Lake due to their proximity to forest fires.
