The Saskatoon Fire Department responded to a structure fire in the 1400 block of Avenue B North shortly before 7 p.m. Wednesday evening.

Firefighters could see heavy smoke and fire coming from the back yard shed and a large tree.

Crew hosed down the exterior of two houses while another crew searched the house to make sure no one was inside.

Hose lines were used to put out the tree on fire as well as two sheds in the backyards.

No one was hurt and now the fire investigator is determining the origin and cause of the fire.
