Four workers were injured over the noon hour Thursday at a highrise construction site in downtown London. Workers were pouring concrete and shoring up the ceiling on the 26th floor at 131 King Street when some of the material collapsed, falling on the workers. They were taken to hospital in stable condition. The Ministry of Labour has been called in to investigate. Two years ago last month, a pair of workers were killed when a floor collapsed at a Wonderland Road construction site.
