Police north of Toronto are working to determine the motive in what they've called a "horrendous" shooting at a condo that left five people, plus the suspected gunman, dead.

York Regional Police say Francesco Villi's victims at the high-rise building in Vaughan, Ont., on Sunday night included three members of the building's condo board.

Court documents indicate the 73-year-old had a lengthy history of threatening members of the board and believed they had a conspiracy to "systematically murder" him.

Police say a sixth shooting victim – the wife of a board member – remained in hospital with serious injuries.

The force also says Villi shot the victims in three different units in the building before an officer shot and killed him.

Ontario's police watchdog has said the suspected gunman was a resident of the building and used a semi-automatic handgun on his victims.
