Three men were injured in an explosion in a home on Cedar Street in Whitby on Wednesday afternoon, says Durham Regional Police.
The police said they were called to a residence on Cedar Street 119 shortly before 3:30 pm. for explosion reports.
The victims were transferred to the hospital with life-threatening injuries, the police said. They have been released ever since.
The first reports indicate that the explosion could be caused by a gas line ignition.
Five firefighting vehicles and 26 firefighters responded to the explosion, which blew the entire side of the house.
Natasha Park, who lives two homes away, said he just returned home when the explosion occurred.
"I went out to my balcony and when I went out I kinda got back with this big bang noise," he told CBC Toronto.
"It was almost like a bomb and a shot sound mixed together like a big batter."
Park said while smelling smoke, there was no fire.
She said she went to investigate and remarked that the house, which belonged to one of her friends – Johnna Yurkovich – "was more or less blown into pieces."
Jurkovic, who was not home during the explosion, said he broke and almost collapsed when he returned and saw the damage.
"I've literally left 10 minutes before blowing out to go get my daughter out. My daughter could have been there and I'm glad everyone is OK," he told CBC Toronto.
"I do not know what to do, everything is gone [and] we will probably not be allowed to return to both. "
