The city has billed the developer of Toronto's Trump Tower about $2,000 over the closing of a large swath of the financial district in late August due to reports of an unstable antenna on top of the building.

Police were called to the Trump International Hotel and Tower Toronto on Aug. 31 after reports of seeing an antenna swaying in the wind. The city had issued an unsafe building order and a section of Bay and Adelaide streets were shut down for the better part of two days as engineers worked to determine if the luxury high-rise was a safety risk to the public.

The building was ultimately deemed safe and the roads were re-opened around 4 p.m. on Sept. 1.

According to a city report released on Friday, the road closures were "appropriate and necessary."

Toronto's acting chief building official John Heggie said although the engineers' findings didn't support the initial reports from witnesses, the city's decision to issue the unsafe building order was the right move.

"After reviewing the facts, Toronto Building and Legal Services staff believe that the city's response was appropriate and necessary to satisfy municipal obligations set out in the Building Code Act for public safety," the report explained.

Earlier this year, Mayor John Tory said the downtwon road closures had resulted in a substantial cost to the city, both in terms of money spent on deploying police officers and the cost to businesses in the area. He said he would look into holding the building's developer, Talon International Development, financially accountable.

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

Friday's report does not provide details about the costs associated with the road closures.
