A Mississauga family is looking for answers after a large piece of ice crashed through the roof of their home Wednesday, coming within a few feet of a woman sleeping.

The loud crash at 1317 Burgess Cres., in the area of Winston Churchill Boulevard and The Collegeway, occurred around 6:30 p.m. Jan. 9.

Carmela Caccavo was asleep but quickly awoke to the “enormous” noise.

The ice had landed a few metres from her bed.

“I was shaking,” she said, adding she is lucky to be alive as she believes the large chunk could have seriously injured or killed her.

Caccavo’s son, Michael, suggested the ice came from a plane soaring overhead at the time.

“2 meters away from my parents bed where my mother was. Thank God no one was hurt. “But if someone was, who would be responsible?” said @DanielCadillac on Twitter.

Transport Canada said that the Caccavos should file a report with them.

“The department takes all reports of possible debris coming from aircraft very seriously and every reported incident is investigated by departmental officials,” spokesperson Sau Sau Liu said Wednesday evening. “If it is determined that the ice came from an aircraft, the department will try to identify the carrier to ensure the problem is rectified. If the air carrier does not remedy the problem, Transport Canada will take appropriate action.”

Each air operator is responsible for ensuring their aircraft operate safely and in compliance with the Canadian Aviation Regulations, Liu added.
