According to the Vancouver Fire Department, the collapse occurred just before 1:30 p.m. at a building on Lougheed Highway between Rupert Street and Boundary Road. Dozens of emergency responders were on the scene late into the night investigating the situation, including the Heavy Urban Search and Rescue Task Force. “A Bobcat was doing some work on the part of the roof of the parkade that caved in,” Epikouros said. Chief Dan Moberg told CTV News. “A section of the top floor car park collapsed into an office space below.” Some witnesses claim that about half a dozen people were trapped inside, but this has not been confirmed by officials. “I was just walking by and I hear a big crash and I just see everybody running out and I’m like, ‘Holy! What’s going on?” said witness Grant William Johnson. “The roof collapses and I see it all end. And I was like, ‘Oh, this is a big thing,’” she continued. In an email to CTV News, BC Emergency Health Services said four ambulances were sent to the scene and two patients were taken to hospital. The extent of their injuries is currently unknown. The investigation is ongoing. CTV News has reached out to the Vancouver Police Department for further updates, but has not heard back.
