Officers responded to a Toronto Community Housing apartment building on Lawrence Avenue East and Mossbank Drive, near Scarborough Golf Club Road, at around 3:30 p.m. Monday.
Investigators initially told Global News that a mother was returning home with her three young children after picking two of them up from school.
The two-year-old girl was in her stroller when the air-conditioning unit fell from the eighth floor of the building and struck her, police said.
Officers told Global News they are conducting a forensic investigation and are looking for any surveillance video or witnesses “to ensure we know exactly what happened,” adding that preliminary information suggests the incident was a “tragic accident.”
There is no word yet on whether charges may be laid, and the investigation remains ongoing.
