A typically-busy downtown block remains closed to pedestrians and traffic the day after employees at Trump Tower reported seeing the building's antenna swaying in the wind.

Bay Street is closed from King Street to Richmond Street, and Adelaide Street is closed eastbound from York Street to Bay.

The roads were shut at approximately 8 a.m. on Monday, when hotel staff called Toronto police to the Trump International Hotel and Tower Toronto, located at 325 Bay St.

A city engineer was brought in to consult with police, and it was determined there was a possible safety risk.

Police said officials do not think there's a chance that the antenna, or any part of it, will fall to the street below, but the nearby streets are closed as a precaution.

On Tuesday morning, Toronto police said roads will remain closed until a structural engineer arrives. Officers estimated the road would be closed until the afternoon.

A statement from the City of Toronto said the owner of the building is required to provide a report from an engineer "that concludes there is no risk to the public."

The statement said the city had been in touch with property management and was awaiting a response.

Addressing reporters at a news conference, Toronto Mayor John Tory said he'd been in touch with officials, and added that he'd advised the owners to "do a better job" of communicating with the city and the public.

"I think one of the frustrations yesterday was the lack of information," Tory said.

He said that he hops to make sure those responsible for the ongoing traffic disruption are held accountable.

"There was a considerable cost and a considerable disruption to the city that resulted from what went on in the last 24 hours," he said.

"I would like to make sure there is accountability for that, both in terms of people who did or didn't do things they should do but also in terms of financial accountability because there is a big cost to this as well."

Talon International Development, a Markham-based developer associated with Trump Development Company, issued a statement Monday evening saying the giant antenna needed further inspection, but that it appeared there was no risk.

"Talon's technical specialist was quickly dispatched to the area, and found that the concerns were unsubstantiated," the company said.

"Talon is continuing its due diligence and is now awaiting a final report from its technical team. As soon as Talon has the final report, the police department will be notified."
