Two families were forced from their rented homes because of a fire early Friday morning on Humber Road in Corner Brook.
The fire was reported shortly before 2 a.m.
The Canadian Red Cross is supplying the five adults and five children with emergency lodging, food and clothing.
Two adults and two toddlers lived in one half of the duplex, while three adults and three children were in the other side of the building. The children range in age from one to 13.
There has been no word on the cause of the fire.
