The Premier is moving forward with her legal battle again Progressive Conservative leader Tim Hudak and his energy critic Lisa MacLeod.
Kathleen Wynne has sent the pair a libel notice, after getting her lawyer to issue a cease and desist letter earlier this week.
Last week, Hudak and MacLeod made allegations that Wynne oversaw the gas plant email deletion. They claim recently released police documents prove that.
These allegations have not been proven in court.
"Premier Wynne gave the opportunity for Mr. Hudak to pull back from his unfounded statements. Unfortunately he did not," Wynne's press secretary Zita Astravas told Newstalk 1010 by email.
During testimony at the government committee looking into the gas plant cancellations on Thursday, Liberal MPP Steven Del Duca asked OPP Det. Cst. Andre Duval if the documents outlined the Tories allegations. Duval said they did not.
However, the OPP is waiting for their tech experts to see if any if the 24 government computers alleged to have been wiped we're accessed after Wynne took office on Feb. 11, 2013.
Police documents allege former McGuinty Chief of Staff David Livingston brought in the tech-savvy boyfriend of his deputy, Laura Miller to delete sensitive information.
Those allegations have also not been proven.
