A small fire forced the temporary evacuation of the Salvation Army shelter on Gottingen Street on Wednesday.
Officials with Halifax Fire and Emergency say the blaze started on the fourth floor.
The Salvation Army says that at some point a shirt was placed over a lamp, eventually causing the shirt to start smoldering and setting off the fire alarm.

Investigators are still working to determine the cause of the fire.
