Police got a call about a man on the roof of the building just north of Mosaic Place on Saturday.
They tried to talk the man down, but instead he threw bricks at the officers.
When the police negotiator showed up, the man tried to get off the building by climbing into the chimney.
He fell down the chimney about 15 metres into a furnace, but he couldn't get out and called for help.
Once firefighters and EMS got him free, the man — who was found with a sword — was charged with mischief and assaulting a police officer.
