The collapse occurred shortly before 1:30 p.m. at a building on Lougheed Highway between Rupert Street and Boundary Road, according to Vancouver Fire Services. “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.” 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.
