There was a loud boom and the house shook as a block of ice, believed to be from a plane above, crashed through the roof of a Mississauga home on Wednesday.

Homeowner Carmela Caccavo said she was still in bed when she heard a “big, big crash” around 6:30 a.m.

“It’s like if you throw something down the stairs. I got scared,” she said. “I turned the light on and I just saw this huge hole on the roof and all the insulation on top of my clothes.”

The chunk of ice landed in the closet of Caccavo’s room.

“I turned the light on and I just saw this huge hole on the roof and all the insulation on top of my clothes, and a piece of ice,” she said. “It just shattered on the floor and went all over my room.”

Caccavo’s son, Michael Caccavo, said that he “woke up right away” when he heard the noise.

“At first, I was in shock and disbelief. I didn’t know what happened,” he explained.

He said the ice chunk weighed about five pounds and landed about two or three metres away from where his mother was sleeping.

“Even if maybe my dad or mom were getting ready in the morning, that’s where they put their clothes on,” Michael Caccavo said. “It’s scary.”

The family believes the ice must have fallen from a plane, as there was no wind or storm that night.

According to flight path data, an Air Canada Rouge flight, scheduled to land at Pearson International Airport at 6:41 a.m., would have been passing right over the house at the time.

It’s unclear how the ice would have fallen from the plane.

The roof has now been patched up, but Michael Caccavo said he believes the damage could cost around $20,000 to repair.

“My mom is shaken up. She’s a little worried. She’s scared a little bit. But, we’re just happy everyone is ok," he said.

Air Canada told CTV News Toronto that they were not aware of the situation and that Transport Canada would be responsible for investigating the incident. 

In a statement Wednesday night, Transport Canada said they were not aware of the incident, but that all complaints about objects falling from aircraft are taken seriously.

“The department takes all reports of possible debris coming from aircraft very seriously and every reported incident is investigated by departmental officials,” the statement read. “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.”
