At Queens Park … The opposition parties want Energy Minister Chris Bentley to produce documents about who made the decision to cancel a proposed gas plant in Mississauga just a few days before last year’s election.

Bentley has said only that the announcement was made through a Liberal party news release and couldn’t say whether Premier Dalton McGuinty ultimately made the call.

Bentley’s comments before a legislative committee come one day after he revealed that relocating the plant will cost 180 million dollars.

The NDP and the Conservatives have accused the Liberals of scrapping plans for the plants to save Liberal seats amid fierce opposition from local residents.

The opposition parties want Bentley to produce documents about the Mississauga plant deal, as well as those related to the cancellation of a proposed gas plant in Oakville in 2010.
