The stage at Downsview Park in Toronto has collapsed, leaving one dead and at least three injured, Canadian news services are reporting. The venue was hosting this evening's sold-out Radiohead concert.

The collapse happened at around 4 pm—an hour before doors were set to open. So none of the victims were audience members.

Radiohead has posted a tweet that contains wording errors making it seem written in haste: "Due to unforeseen circumstances tonight's at downsview park tonight has been cancelled. Fans are advised not to make their way to the venue."

"Several stage accidents

The stage collapse is one of several high-profile accidents at concert sites throughout North America in recent years — though the others happened during inclement weather and with fans nearby.

 In August 2009, the collapse of a stage at Alberta's Big Valley Jamboree in Camrose, Alta., killed a 35-year-old woman when a storm blew in.
 
In July 2011, a stage at Ottawa Bluesfest fell in a storm just moments after the band Cheap Trick had left the stage. No one was killed, but several people were treated for injuries.

On Aug. 13, 2011, a wind gust toppled the main stage at the Indiana State Fair, killing five people and injuring 45 other as they were waiting for the band Sugarland to perform. A study determined the stage was poorly designed.

The Ontario Ministry of Labour has been called in to investigate Saturday's disaster in Toronto."
