Ottawa Sinkhole Opens Up On Rideau Street In Heart Of Downtown

A massive sinkhole in the heart of downtown Ottawa has snarled traffic, prompted evacuations, and swallowed a minivan.

A water main break caused the giant chasm to open up Wednesday morning on Rideau Street near Sussex Drive, outside the Rideau Centre mall and steps away from Parliament Hill.

Burt Blaisdell, a site superintendent who is working on new store in the Rideau Centre mall, said he and his crew left quickly once the bells to evacuate the building started sounding.

"It's a normal fire alarm came up to evacuate. They never said why," Blaisdell told The Huffington Post Canada.

He was allowed to back in to get the workers' keys and wallets, but wasn't permitted to stay more than 10 minutes inside the building.

"They are lucky that someone didn't get hurt. Guys were working there," Blaisdell said.

CTV Ottawa tweeted that a minivan swallowed up by the sinkhole is now under water.

The water main break also caused a gas leak in the mall and the adjacent Westin Hotel, which were evacuated Wednesday morning, according to the National Post.

Twitter users wasted no time in making jokes about the sinkhole.

There's already a parody Twitter account.
