The city tweeted there was not a tunnel collapse, rather a piece of “shotcrete” fell from the roof of the tunnel. Shotcrete is a layer of temporary spray-on concrete.
Mayor Jim Watson told media about 13 pounds of material fell.
Work has been halted until the Ontario Ministry of Labour can investigate.
Roads have reopened.
A small amount of shotcrete fell within tunnel in construction zone. This was not a tunnel collapse.

I'm on-site. No tunnel collapse. Staff are reporting a small construction incident with minor injury to one worker. Glad everyone is safe.
