McGuinty aide David Livingston found guilty in gas plants trial

One of former Ontario premier Dalton McGuinty’s top political staff was found guilty Friday of criminal charges for wiping government computers following the cancellation of two gas-fired power plants.

David Livingston, who was McGuinty’s chief of staff, was found guilty on charges of unauthorized use of a computer and a charge of attempting to commit mischief to data.

Meanwhile, his deputy Laura Miller was found not guilty on both counts.
