Investigators say the caller is a 10-year-old hearing impaired and developmentally delayed student who cannot speak and attends a Sarnia public school.
An educational assistant at the school heard the story about the 911 calls and informed a teacher.
The teacher was aware that the student enjoyed playing with gadgets and lived in the area police had identified as the source of the calls.
The parent of the student had removed the SIM card before giving the cellphone to the child, believing that it would have no service capabilities.
Police say the child was not aware that 911 was being contacted each time a call was made.
