Emergency crews responded to a dramatic scene in downtown Toronto on Friday evening after a fire erupted on the roof of a building under construction, triggering a series of explosions that sent debris raining onto the street and forced the closure of several major roads in the city’s entertainment district.
Toronto Police Service said the incident was reported around 6:02 p.m. near the intersection of Richmond Street West and John Street, a bustling area surrounded by restaurants, offices, and residential towers. Officers and Toronto Fire Services responded in force to what quickly escalated into a multi-alarm emergency.
According to fire officials, the blaze originated on the roof of a commercial building currently undergoing construction. The fire ruptured propane cylinders stored at the site, causing heavy flames and thick plumes of black smoke that were visible across the downtown core. Witnesses reported hearing multiple loud explosions that rattled windows in nearby buildings.
Videos posted on social media showed dramatic footage of fireballs erupting from the rooftop, with smoke billowing high into the evening sky. One resident filming from a balcony on nearby Widmer Street captured the moment several explosions occurred in rapid succession, the footage quickly going viral on platforms including X and Instagram.
“It sounded like bombs going off,” said Sarah Chen, who was dining at a restaurant on John Street when the first explosion occurred. “Everyone ran outside, and we could see flames shooting up from the construction site. It was terrifying.”
Authorities moved swiftly to establish a safety perimeter, closing Richmond Street West between Peter Street and Duncan Street. Pedestrian access was also restricted in the immediate area as firefighters worked to contain the blaze and prevent it from spreading to adjacent structures. Several nearby buildings were evacuated as a precautionary measure.
Toronto Fire Services deployed aerial ladder trucks and multiple hose lines to attack the fire from several angles. The challenging rooftop location complicated suppression efforts, as crews had to navigate the partially completed construction to reach the seat of the fire. The ruptured propane cylinders added an additional layer of danger, with fire officials warning of the potential for further explosions.
In an update issued later Friday evening, police confirmed that the fire had been extinguished. Remarkably, no injuries were reported among either firefighters or civilians, though officials acknowledged the situation could easily have turned deadly given the explosions and falling debris.
“We were fortunate that the area immediately around the construction site was not heavily populated at the time of the initial explosions,” said Toronto Fire Services District Chief Mark Thompson. “Had this occurred during the lunch hour with more pedestrians on the street, we could be telling a very different story.”
Some road closures remained in effect late into the evening as investigators began examining the scene. The Ontario Fire Marshal’s office has been notified and is expected to participate in the investigation to determine the cause of the fire and whether proper safety protocols for storing propane at the construction site were being followed.
Construction industry observers noted that the incident raises questions about the storage and handling of pressurized cylinders on active building sites in dense urban areas. Under Ontario’s Fire Code, propane cylinders must be stored in accordance with strict guidelines, including minimum distance requirements from ignition sources and proper ventilation.
The identity of the construction company responsible for the project has not been publicly disclosed. City officials said any regulatory violations discovered during the investigation could result in charges under the Fire Protection and Prevention Act.
