Auditor General Sheila Fraser is set to deliver a report Tuesday on the federal government's delivery of the much-hyped Economic Action Plan, which was designed to combat the effects of the recession.

The program, introduced in the 2009 federal budget, is intended to provide $62 billion in stimulus funding over two years "to help protect and create jobs and invest in future prosperity."

A damning report could be politically explosive to the Conservative minority government, while a favourable report would bolster Harper's recession-fighting resume.

Fraser -- who exposed questionable spending during the 2002 and 2004 Quebec sponsorship scandal that eventually helped the Conservatives unseat the Liberals -- looked at whether the rules were followed and whether all the projects that received funds, should have.

Transport Minister Chuck Strahl, who is responsible for infrastructure, has a news conference scheduled immediately following the release of Fraser's report on Tuesday afternoon.

However, the government will take a couple of days to pore over the report before issuing a full response to the entire report.

Fraser will also look at two other contentious issues: The regulation and supervision of big banks and the military purchase of Chinook and Cyclone helicopters.

The Conservative government has faced heavy criticism over the helicopter purchase, with the opposition complaining about the cost and the tendering process.

The Sikorsky Cyclone helicopters were actually ordered by former prime minister Paul Martin in 2004 for $1.8-billion, to replace the aging Sea King helicopter fleet. They are behind schedule however, with delivery not expected until June 2012.

The $1.2-billion contract for 15 Boeing Chinook helicopters was signed by the Harper government in 2009, along with a 20-year, $2.2-billion maintenance and support contract. They are set for delivery in July, 2013.

Fraser's take on the helicopters could also give the opposition ammunition in its criticism of Canada's latest controversial military purchase -- $9 billion worth of F-35 fighter planes and $7 billion in maintenance costs.

Fraser is scheduled to table her report in Parliament at 2 p.m. ET.
