A toddler was seriously injured after she fell out of a fifth-floor window in southwest Calgary on Sunday morning.

Police said the girl, who is almost three, was leaning on the screen of an open window at an apartment in the 700 block of 14th Avenue S.W. when it collapsed and she fell to the ground.

The girl was taken to Foothills hospital with serious, life-threatening injuries.  Her condition was later upgraded to stable, said EMS spokesman Stuart Brideaux.

Investigators have determined it to be an accident with no criminal intent.

Neighbour Cassi Stevens ran out to her balcony when she heard the commotion.

"We saw the little girl just laying on the ground. She wasn't crying, she was unconscious," she said. "You could tell she was really badly hurt."

Officials with Alberta Social Services and the police victims assistance unit are helping the parents and family members.

Another neighbour who witnessed the aftermath of the accident, Shyelle Welker, demonstrated in her unit how the building's window screens can give-way with a couple of firm pushes.

"I felt so helpless for them," she said. "It's still replaying in my head. It's the shock factor."

Police Duty Insp.Chris Butler said city inspectors are looking at possible building code issues or safety violations at the building.
