Fire crews had to battle flames and the cold weather on Tuesday night when a fire broke out in the city's southeast. 

"Conditions like this, with it being so cold and icy, it is always tough, but we circulate our crews into rehab regularly so it's not too much of a concern," said acting district fire chief Mike Van Teetering.

Crew found heavy smoke pouring out the back of the house in Penbrooke when they arrived, but were able to quickly get things under control. 

"They mounted an aggressive interior attack and had a quick knock down of the fire and the lone occupant of the house was able to escape with no injuries," said Van Teetering. 

Authorities continue to investigate the cause of the fire.
