Andrew Saxton, parliamentary secretary to the President of the Treasury Board, has told the House of Commons the Conservatives feel they've delved deep enough into the issues surrounding the cost of the stealth fighters.
Media reports say the Tories are expected to pass a motion to end the hearings at a closed-door meeting of the Parliamentary public accounts committee today.
The move would come as only four weeks remain on the parliamentary calendar before the summer break.
The committee has been studying the auditor general's hard-hitting report on the acquisition of the costly jets.
The auditor general said in his report that Parliament didn't get the full picture on the costs of the 65 jets, which are closer to $25 billion rather than the $16 billion the Tories publicized.
The F-35 program is designed to replace the country's aging fleet of CF-18 jet fighters.
