Coming less than a year after a deadly stage collapse in Indiana at a Sugarland concert, another concert-related accident has claimed the life of one man and left several others injured.

Just one hour before a Radiohead show in Toronto’s Downsview Park on Saturday, the enormous metal roof covering the outdoor stage collapsed, pinning a man who was later pronounced dead at the scene. Several crew members and stage hands were on the stage when it happened, but most managed to get out of the way in time, although at least three other men were taken to the hospital with injuries. The concert, obviously, was cancelled, although Radiohead has yet to issue a statement.

Because there weren’t heavy winds rolling through when the incident occurred, officials are investigating exactly what caused the collapse. If human error is found, those in charge of erecting the venue could have a big problem on their hands. After the Sugarland stage collapse, the Indiana Department of Labor announced there were worker safety violations and fines were doled out amounting to almost $90,000.

The victim’s name hasn’t officially been released by authorities, although media sources learned it was a man in his 30’s. However, Twitter users are saying his name was Scott and are offering condolences via the social media source.
