A four-alarm fire broke out early Wednesday at a waste transfer facility on Disco Road, near Highways 427 and 409 in Toronto. Fire crews were called to the industrial site just before 4 a.m. and quickly scaled up their response as the blaze took hold inside the building, which handles the transfer of waste.
According to the Toronto fire commander who spoke about the response, crews initially launched an offensive attack before transitioning to a defensive one as conditions changed. Firefighters also cut additional holes in the roof of the structure to reach the seat of the fire and apply more water from above, a tactic used when flames are hard to get at directly.
The commander said the fire was classified as a four-alarm blaze because of the sheer scale of the response required to bring it under control. In total, 38 fire vehicles and more than 120 firefighters were needed at the scene, one of the larger deployments the city's fire service has mounted in recent months.
Officials noted that fires of this kind are typically deep-seated, meaning the flames burrow into piles of material and are difficult to fully extinguish. That characteristic posed additional challenges for crews working to knock down the fire and prevent it from flaring back up once the main flames were suppressed.
Despite the size of the fire, there were no reports of anyone being hurt. The commander confirmed that no one was inside the facility at the time the fire started and that there were no injuries. He added that the building's sprinkler system did activate inside, helping to slow the spread before crews arrived.
With the fire brought under control, crews were expected to remain at the scene for a full 24 hours to monitor the situation. Deep-seated fires can smoulder and reignite long after the visible flames are gone, so firefighters typically stay on site to watch for flare-ups and douse any hot spots that emerge.
The blaze also marked the second time in less than a year that fire crews have had to respond to this particular facility in large numbers. The repeat incident at the same waste transfer station is likely to draw scrutiny over conditions at the site, even as the immediate priority remained making sure the fire was fully out.
