Residents in London, Ont., Rushed out of homes Wednesday night after a vehicle drove into a residence in the city's east end, causing an explosion. 12:16

Acting Deputy Fire Chief Jack Burt said crews were evacuated.

"So we've got a significant debris field from an explosion that actually goes over a block area at this point," he said.

Burt said more than 50 firefighters were at the height of the fire.

Here's a breakdown of injuries from the fire:

  • Four firefighters were hurt. Three people have been hospitalized in a serious but stable condition.
  • Two police officers were also taken to hospital, but have since been released.
  • A civilian was taken to hospital. That person's condition is not known.

Neighbors came quickly to the explosion, offering a place to sleep for those told to leave their homes. Others were circulating with water and coffee.

"I could see sparks exploding over the trees," said Joanne Bishop, resident in the area. "These are our friends and neighbors, so I think people are scared right now."

The city has set up an Emergency Operations Center at 275 Boler Rd.

With so many people unable to go home, the City of London arranged for hotel rooms for dozens of families. It was still unclear how long the evacuation would have been.

"In my 20 years in the fire service, I've never seen an event of this nature," said Burt.

He said the home was "reduced to rubble" and nearby homes have extensive damage.

Could have been much worse

Burt said it was gone the area was evacuated when the gas leak was first detected or "this could have been a very different story."

The fires were extinguished by 10 a.m. Thursday.

Mayor Ed Holder said the city has been rented for their homes.

"All these people have had to endure one of the most terrifying nights in their lives, our hearts and prayers go out to them and their families," he said.
