Provincial police in Ontario, Canada, said on Jan. 31 that they have charged former engineer Robert Wood, 64, with three counts of criminal negligence related to his role as inspector of an Elliot Lake mall roof that collapsed on June 23, 2012, killing two store employees.

Wood, former president of M.R. Wright & Associates Inc., Sault Sainte Marie, faces two criminal counts related to the deaths and one related to injuries to another person.

A police investigation, with analysis by four Canadian engineers and contractors, began in July 2012.

Wood testified to an inquiry commission that the Algo Centre Mall roof was sound in May 2012, only weeks before it fell.

More than 125 people testified at the panel's hearings. The commission report is set for completion in late October.

Ontario Provincial Police Detective Superintendent David Truax said Wood was arrested on Jan. 31 and is set to appear in an Elliot Lake court on March 25, but Truax declined further comment on whether charges would be brought against anyone else.

Neither Wood nor his attorney would comment to Canadian media.

Wood faces a possible life sentence on the fatality charges and could be charged separately by the Ministry of Labour, says The Toronto Star.
