Many Orléans residents were jolted awake early Monday morning after an explosion caused by a gas leak at a residential construction site rocked their homes several kilometers away.

Two men were pulled from the rubble in the hours after the blast and taken to hospital in serious but stable condition, while two children and two other adults were taken to local hospitals in stable condition. Another seven people were treated at the scene and released.

The Office of the Fire Marshal is leading the investigation into the Orléans explosion, while a fuel safety investigator and inspector from a technical standards and safety agency is assisting. The Ontario Department of Labor is conducting its own investigation.

Here’s what we know about how events unfolded from the moment of the explosion:

6:17 am (and 22 seconds) The explosion

Footage from a resident’s ring camera shows the moment an explosion rocked a residential area near Tenth Line Road, releasing a fireball several stories into the air and lighting up the early morning sky.

6:18 am 911 flooded with calls

Seconds later, multiple 911 calls poured in from residents about an explosion in the area of ​​Tenth Line Road and Shallow Pond Place.

They felt their homes tremble miles from the blast radius. In the initial confusion, some local residents later told CBC they thought there had been an earthquake.

Divya Suri described seeing her windows blown out, the ceiling cracked and a door blown out of its frame.

Insulation could be seen scattered over houses and cars.

Drone footage captured by CBC showed the houses under construction where the blast took place were leveled.
