The nightmare was supposed to be over. After a relentless weeks-long blaze tore through the walls of two east-end Toronto condo towers last winter, residents finally returned home—only for a second inferno to erupt Monday in the exact same spot.
Fire Chief Jim Jessop revealed the chilling truth Tuesday: this new fire was not an accident of fate, but a direct consequence of the very workers hired to fix the damage. Their saws, grinding against concrete, spat sparks into a hidden layer of rigid wood-fiber insulation, igniting it once again.
The flames raced through the gap between 11 Thorncliffe Park Drive and 21 Overlea Boulevard, demanding an army of over 100 firefighters and a dozen trucks to battle the three-alarm monster. Yet miraculously, no one was hurt, and no one was forced to flee their homes this time.
“We’ve been monitoring the air constantly—for smoke, for carbon monoxide,” Jessop declared, his voice carrying the weight of exhausted residents still raw from the 2025 ordeal. “We won’t disrupt their lives any more than we have to.”
The city had issued two permits for remedial work after the original fire, ordering the removal of the TenTest insulation and the filling of the gap with fire-stopping material. But the plan failed catastrophically.
Kamal Gogna, Toronto’s chief building official, didn’t mince words: every single operation has been halted immediately. “Work will not continue until we are satisfied it can be done in a safe manner,” he said, demanding a new construction management plan from the property’s engineer before any blade touches concrete again.
Gogna admitted the saws were being used, and a methodology was supposedly in place. But the sparks didn’t care about paperwork. The TenTest insulation, commonly approved for separating structures, turned into a hidden fuse that no one could fully reach.
That earlier fire in November 2025 lasted over two weeks, forcing roughly 400 units to evacuate. Most residents couldn’t return until January. Jessop called it the most complex situation in his 30-year career—a smoldering labyrinth that crews could barely access.
Now, the same nightmare has clawed back. The investigation is closed. The cause is known. And a city that thought it had healed is holding its breath, staring at the walls that keep secrets, waiting for the honest certainty the chief promised.
