A stage collapse at Toronto's Downsview Park killed one person and injured at least three others setting up for a Radiohead concert, the CBC reported, citing emergency responders.
One person was transported to Sunnybrook Hospital in serious condition while two others were being assessed at the scene, CBC said.
Downsview Park tweeted that the concert was canceled. Show promoter Live Nation Entertainment also announced the show was canceled.
The collapse occurred at 4 p.m. ET, about an hour before venue gates were scheduled to open.
"From what I understand the piping which makes up the roof structure where lights and what not are supported collapsed down and there was workers setting up the stage at the time," Toronto Fire Services Captain Mike Strapko told broadcaster CP24.
