As of this morning, the downtown is largely intact. The hospital is still standing. Municipal buildings and the airport also remain intact.

Sreenivasan the cbcs evan dyer says, that means theres no timetable for when the evacuees will finally be able to return home. Some know for a fact that their homes have been destroyed. Others are still living with the uncertainty of not knowing, some know their homes are safe, but perhaps are in the path of fire. Sreenivasan but, melissa blake, the mayor of the regional municipality of wood buffalo, says theyll make it. We are a strong and resilient community.
