Construction is still underway at a gas-fired Mississauga power plant the Ontario Liberals promised to move during the recent provincial election.

The Liberals made the promise on Sept. 24. But nearly three weeks after the Oct. 6 election, CTV News' helicopter captured images of massive generators being moved to the site, located in the provincial riding of Mississauga South.

Police vehicles were paid to escort the trucks, and hydro crews were hired to move overhead wires.

This had Hudak furious on Monday.

"If they're going to cancel the plant like they said they would, then cancel it," he said. "Don't delay. Don't run up the bill. We're already $16 billion in debt."

In a news release, the Tories said: "It has been one year since Dalton McGuinty broke a similar contract to scrap a power plant in Oakville, and taxpayers still don’t know how much it will cost them."

Hudak said Premier Dalton McGuinty must explain why the work is continuing, how much it is costing taxpayers to keep building and what it will cost to break the contracts for the Oakville and Mississauga plants.

In response, Energy Minister Chris Bentley sent out a news release.

“The Ontario government is committed to relocating the natural gas plant originally planned for Mississauga," he said.

"The government will work with the company to find a suitable location for this plant. More information will become available as discussions progress.”

NDP Leader Andrea Horwath said the Liberal government should be taking the plant apart, not putting more money into building it.

She wanted to know how much this situation is costing taxpayers.

Mississauga South Liberal MPP Charles Sousa said he didn't know when construction would stop at the plant. "We've made a commitment that we'll have it moved, and we're going to deliver up," he said.

When the Liberals promised to move the plant, Sousa -- named minister of citizenship and immigration in last week's cabinet shuffle -- was the incumbent candidate in the hotly contested riding.

Hudak made a campaign stop there on Oct. 5, the day before the vote, to note that work was still taking place on the site despite the Liberal promise.

On Oct. 6, Sousa won re-election with 50.6 per cent of the vote. His Tory opponent finished 14.5 percentage points behind him
