TORONTO

It’s Premier Kathleen Wynne’s signature on an Oakville gas plant record.

Everyone could agree on that Thursday, but opinions veered sharply on the significance, if any, of this latest twist in the cancelled gas plants’ saga.

Tory energy critic Vic Fedeli said the Liberal government failed to turn over the cover page of a cabinet document authorizing the Minister of Energy to enter into negotiations with TransCanada Energy Limited for damages stemming from the political decision in 2010 to cancel the Oakville gas plant.

The cover page was signed by four cabinet ministers, including Wynne.

“This is the cover up of the cover up of the cover up of the cover page,” Fedeli said Thursday after receiving the record.

House Leader John Milloy said the document was created at a July 29, 2011, cabinet meeting, long after the decision to pull the plug on the Oakville plant. “That was a government-wide decision and the premier was part of the government at the time.”

A government committee set up to look into the gas plants’ cancellations demanded the release of all related energy ministry and Ontario Power Authority (OPA) documents last year.

When documents kept surfacing — after the government assured the legislature that all had been revealed — another government committee began investigating whether records were being suppressed.

Fedeli said a draft form of the cabinet decision appeared in one “document dump” without the attached letter linking it to Wynne.

“I allege that it was not in the documents that we had because her signature is on this,” Fedeli said. “Clearly the cabinet was well aware of the deal.”

The premier’s office says the cover page wasn’t included because it was a cabinet document that had not been requested initially by the committee.

NDP MPP Peter Tabuns said of the cover page, “We knew that the cabinet was approving this process. So this does not surprise me.”

Auditor General Jim McCarter will release the results of his investigation into the cancellation of the Mississauga plant on Monday, followed at a later date by an assessment of the Oakville plant costs.
