A B.C. Liberal political staffer has resigned and his conduct has been referred to the RCMP by the Information and Privacy Commissioner after an investigation of his deletion of government emails that were being requested under freedom of information laws.

Commissioner Elizabeth Denham said three investigations showed records were intentionally destroyed to avoid public release. One of those requests was was for records related to public hearings on risks of travelling along Highway 16 in northern B.C.

NDP leader John Horgan said the investigation shows the conduct of B.C. Liberal government staffers, including Premier Christy Clark’s deputy chief of staff Michele Cadario, reveals “a culture of deception, a culture of deceit, a culture of delete, delete, delete.”

Citizens’ Services Minister Amrik Virk told reporters the reference to the RCMP is related to transportation ministry staffer George Gretes testifying under oath to the commissioner. Denham said Gretes lied about his actions while under oath.

Virk said the government has accepted Gretes’ resignation and has called on former information and privacy commissioner David Loukidelis to respond to Denham’s finding that records were routinely deleted in violation of freedom of information legislation.

Denham started investigating the Highway 16 information request after a complaint from Tim Duncan, made after Duncan left his job as executive assistant to Transportation Minister Todd Stone. Duncan told the commissioner that Gretes deleted a series of emails from Duncan’s office computer in December 2014 after they were requested under freedom of information law.

Stone told reporters Thursday he has also “triple deleted” his own emails, and that he disagrees with Denham’s interpretation of the Freedom of Information and Protection of Privacy Act.

“I adhere to the act,” Stone said. “I expect all of my staff to adhere to the act.”
