MONTREAL--Former Aveos employees plan to demonstrate outside a Quebec courthouse today.

While they protest outside, their lawyers will oppose a recommendation to sell the insolvent aircraft maintenance firm's engine repair business to Lufthansa Technik.

The head of the machinists union says it may seek a delay or injunction to prevent the sale of this segment of the business despite Air Canada's insistence that a deal be concluded by tomorrow.

Chuck Atkinson, district chairman of the International Association of Machinists and Aerospace Workers, says the German company won't preserve jobs in Canada.

He says a competing bid from Vancouver-based M-T-U Aero Engines would.

But the court-appointed chief restructuring officer says both bids appear to be equal in terms of jobs creation in Quebec, although the M-T-U would create up to 130 jobs in Vancouver.

In a report to the court, he says M-T-U's offered price was about half the price offered by Lufthansa.
