Ontario's legislature will continue to debate a contempt motion surrounding the Mississauga and Oakville gas plant cancellations in committee hearings.

The same motion which was debated in the fall before the legislature was prorogued was brought back to Queen's Park by the Tories on the first day of debate in the new session.

The issue is whether or not the Liberals knowingly held back thousands of documents related to the cancellations.

Government house leader John Milloy maintains he and then energy minister Chris Bentley had believed all the documents were released last September despite thousands more made public weeks later.

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

Speaker Dave Levac ruled the issue can be sent back to committee, with a report on its findings due within 90 days.
