A large pane of glass fell Tuesday afternoon from the 34th floor of the Trump Tower on Bay Street.
Constable Tony Vella, spokesman for the Toronto Police Service, said the glass fell just after 4 p.m. onto the sidewalk as well as on the road. Some cars were damaged, but no people were injured, he said.
Dorenda McNeil, a spokeswoman for the Trump International Hotel and Tower Toronto, said the fallen glass is not related to the structure of the building.
"The panel appears to have been dropped by a worker during installation," Ms. McNeil said.
Police blocked off the intersection at Bay and Adelaide Streets while they investigated. Some Toronto Transit Commission buses were rerouted as a result of the road closing.
The affected TTC routes were the 144 Don Valley Express, 143 Beach Express, 141 Mount Pleasant Express, 509 Harbourfront, 145 Humber Bay Express, and the 6 Bay.
Constable Vella said the road closing could last "a couple of hours at least."
The Ministry of Labour was also investigating the incident, Constable Vella said. The ministry has not yet returned a phone message for comment.
The 65-storey Trump Tower is a luxury condo hotel and one of the tallest buildings in Canada. Construction of the tower began in 2007, and it opened on Jan. 31, 2012. It has 261 hotel rooms and 118 condos.
This is not the first time glass has fallen from the Trump Tower. A piece of glass reportedly broke on an early Saturday morning in March when high winds caused scaffolding to crash into the building. Nobody was hurt in that incident either. At the time, Donald Trump Jr., executive vice-president of the Trump Organization, told Reuters that one piece of broken glass doesn`t "speak to the rest of the building."
"If you know anything about construction, that kind of thing just happens," said Mr. Trump Jr. in an interview with Reuters before the official ribbon-cutting opening of the hotel.
