An attempt to broaden the scope of a committee looking into the gas plant cancellations has been ruled out of order.

Earlier in the day, the premier underlined she wants to delve deeper into the planning and why the cancellations in Mississauga and Oakville happened in the first place.

However, the justice committee says it can't adjust its own parameters, noting that's something only the legislature can do.  The Tories rushed to call this motion drawn up by Kathleen Wynne a delay tactic by the Liberals.

Along with expanding what the committee can look into, Wynne says she wants to make a list of files available from across the government, including the premier's office. Over 56,000 documents have already been released.

It's something opposition had been calling for.

In Question Period, the Tories called the Liberals out, claiming the government is now admitting more documents exists. But Wynne maintains the last search only asked for documents from the Ontario Power Authority (OPA), the Minister of Energy's office and the Ministry of Energy.

Progressive Conservative House Leader Jim Wilson wants files from the Liberal Party itself, given the decision to cancel the Mississauga plant came during the 2011 provincial election campaign.

The NDP continues calls for a public inquiry, something the Liberals have dismissed as too costly.

The gas plant cancellations are estimated to have cost taxpayers $230 million.

The premier has said she would testify at the hearings if asked.
