MONTREAL (AP) — Bombardier's CEO says employees should expect additional aircraft production cuts that may lead to more layoffs as the plane and train maker adjusts to dwindling demand.

The Montreal-based manufacturer, which has a rail-car assembly plant in Plattsburgh, has already announced 4,400 layoffs this year because of lower demand for its business and regional jets.

The lack of orders will force the company to consider increasing that number, CEO Pierre Beaudoin told reporters Monday after addressing the Canadian Club of Montreal.

Bombardier is the world's third-largest aircraft manufacturer.

Details of the changes will be announced before the end of January. The company discloses its third-quarter results on Dec. 3.

Beaudoin says it's a tough market for commercial aircraft.
