A recurring fire at two Toronto highrises in Thorncliffe Park has raised concerns about the safety of insulation trapped within concrete walls. Fire crews reported that the blaze burned through the same materials that caused a massive evacuation of 400 units late last year. This incident underscores the critical need for safer building envelopes and rigorous maintenance of older highrise structures. While owners implemented hoarding measures to isolate the area, the repeat occurrence points to systemic issues with specific legacy insulation materials.
