TORONTO — A massive stage collapse hours before a Radiohead concert was to begin Saturday left one person dead and three others injured, officials said.

Emergency Medical Services deputy commander David Viljakainen said a man who was trapped under the rubble was pronounced dead at the scene. Officials said he was in his mid-30s.

A 45-year-old man was hospitalized with a head injury and two others were treated at the scene for minor injuries at the Downsview Park venue, said Viljakainen.

The venue said on its website that the sold-out concert was canceled.

Fire Services Platoon Chief Tony Bellavance said officials were alerted to a person trapped under the rubble and crews assisted in extracting the victim. "It was a crushing injury that killed the man," he said.

Police spokesman Tony Vella said crew were setting up the stage when it collapsed.

"They were setting up when the top portion collapsed on top of them. Unfortunatly, four people were hurt. The remainder of the people, when they heard the stage coming down, ran from the area," Vella said.

Dusty Lalas, an employee with Toronto Radio Station "The Edge," which was sponsoring the concert, said the structure suddenly caved in.

"There was a loud crash and it sounded like sheet metal and lightning and we just saw the stage collapse," Lalas said.

Radiohead tweeted that "due to unforeseen circumstances tonight's concert at downsview park tonight has been canceled. Fans are advised not to make their way to the venue."

Radiohead's website had listed the concert as being sold out, with 40,000 tickets sold.

Jaime Rivest, 33, said at around 4 p.m. the stage suddenly came down, crumpling and falling onto itself.

"It was like a tornado hit the stage and in just moments the stage came down with metal everywhere," she said.

Rivest said security officials rushed to evacuate the area. She said there was possibly about 1,000 people there hours before Radiohead was to take the stage at 9:30 p.m. The doors for the show opened at 5 p.m. and other acts were scheduled to perform.

Police said the park wasn't full, but there was a considerable crowd of people already waiting for the show amid sunny and clear conditions.

Viljakainen said the Ministry of Labor would investigate to determine the cause of the collapse.

There have been a number of concert stage collapses in recent years.

In Canada, one person died and several people were injured when the stage went down at Bluesfest in Ottawa last July, and one person died and more than a dozen were injured in 2009 when a powerful windstorm caused the main stage to collapse at the Big Valley Jamboree near Camrose

Six people died last August when the stage collapsed at a Sugarland concert in Indianapolis; five died in Belgium when a storm swept in and toppled the stage at the Pukkelpop Festival.



CLARIFICATION: A headline elsewhere on the site has been edited to emphasize that the collapse took place prior to the concert.
