It could be several days before we find out what caused the collapse of a parking garage in downtown Windsor.

The site’s in the Ministry of Labour’s custody now and structural engineers are investigating.

It means it could be some time before residents living in the apartment building next to the collapse can go back home.

They’re staying at a downtown hotel. 

The state of emergency continues but the professional building at 1368 Ouellette is open although some businesses are calling their clients.
