Bentley ran for the provincial legislature in the 2003 general election, contesting the riding of London West as a Liberal.
[9] Bentley was soon mired in controversy over the government's decision made during the election campaign to scrap unpopular gas plants being constructed in Mississauga and Oakville - the move was seen as a politically expedient one made to improve the Liberal Party's chances of retaining the 5 ridings it held in the area.
The election returned a minority government and the emboldened opposition demanded that Bentley's ministry release all documents related to the decision.
After it became known that there were an additional 20,000 documents Bentley was cited by a rare contempt motion by a legislative committee and was facing a contempt motion of the legislature when McGuinty unexpectedly ended the legislative session by proroguing the legislature on October 15.
