Speaking at a news conference Wednesday, Toronto Fire Services Chief Jim Jessop said city engineers have recommended causing significant damage to units with the adjoining burning wall. We understand this is hard to hear for those impacted, he said. We know residents are eager to return home and we share that urgency, but safety must come first. Jessop has called the five-alarm blaze, which originally started on Nov. 27, one of the more complex he's seen in his career.
