They were setting up when the top portion collapsed on top of them. Unfortunately, four people were hurt. The remainder of the people, when they heard the stage coming down, ran from the area.
A force spokesman later tweeted that once the structure was deemed safe to work around, forensic officers would begin a joint investigation with the coroner and the Ministry of Labour.
Tony Bellavance, Fire Services Platoon Chief in Toronto, 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.
Ian West, Mr Johnson's drum teacher in Doncaster, said his former pupil toured the world with famous bands, including Radiohead and Keane.
It was a very, very big shock. He was a great student and a great drummer. He got a lucky break and made the most of it, he never looked back.
The list of bands he worked with was endless, his CV had every band worth their salt on it, a lot of British bands and world class bands.
Mr West said he taught Mr Johnson for three years about 10 years ago.
He was a fantastic guy, never down, very enthusiastic. He was very thoughtful and would do anything for you, he was spot on.
