Huge sinkhole opens in downtown Ottawa, forcing evacuation of mall and businesses

A large sinkhole closed down part of the Canadian capital on Wednesday and forced the evacuation of businesses a few blocks from the national parliament, three weeks before Ottawa is due to host a summit of the leaders of Canada, Mexico and the United States.

The sinkhole formed on a normally busy downtown street in an area that has been under construction for Ottawa’s new light-rail transit (LRT) system. City officials said the cause of the sinkhole, spanning an entire four-lane road, was not yet known but earlier gas and water leaks have been contained.

“It’s premature at this point to make the connection to LRT, although that could very well be the possibility,” Mayor Jim Watson told a news conference.

Officials said there were no reports of injuries or missing people. The Canadian Broadcasting Corporation showed footage of a van parked on the side of the road falling into the sinkhole.

Nearby buildings that were evacuated remained closed, including the Rideau Centre shopping mall, which is owned by Cadillac Fairview, a unit of the Ontario Teachers’ Pension Plan.

Buses in the area were being rerouted, and officials told Ottawans to expect travel delays on Wednesday and Thursday morning. It was the second sinkhole in downtown Ottawa in as many years.
