The deleted emails investigation continues, with OPP detectives searching a data storage company in Mississauga Wednesday.
It's all part of a criminal investigation into emails discussing the Mississauga and Oakville gas plant cancellations said to have been wiped from computers at Queen's Park.
This comes a few months after officers searched the premier's office.
OPP spokesperson Sgt. Carole Dionne confirms a search warrant was executed but isn't getting into specifics when discussing the raid, unable to give information about what was seized.
Dionne also wouldn't speculate the next steps in this investigation or how long it could take.
The investigation into these deleted emails began when Tory MPP Vic Fedeli - then Progressive Conservative energy critic - requested the OPP look into things.
Fedeli says he's not surprised to hear of the search.
He says this just backs up what the Tories have been alleging all along, that staff in the former premier's and energy minister's offices were part of a cover-up regarding the gas plant cancellations.
NDP House Leader Gilles Bisson says Wednesday's search is deeply troubling, given police had to have some lead to get a warrant issued.
In a statement, Kathleen Wynne's office says "Since day one, the Premier has been open and transparent about the Mississauga and Oakville gas plant relocations."
