An enormous sinkhole swallowed three lanes of Rideau Street and a parked van on Wednesday morning, forced the evacuation of the Rideau Centre and nearby businesses, and left the downtown core in a state of chaos that could last for days.

As the city moved “from response to recovery” mode late Wednesday afternoon, the Rideau Transit Group, builders of Ottawa’s light rail transit system, began pumping out water and filling the gaping hole with concrete to stabilize the area and protect building foundations exposed by the collapse. Building code inspectors were working with structural engineers to determine when affected buildings could reopen for business.
