Bombardier is poorly managed company. With end of corporate welfare by Federal government it's very difficult for Bombardier to survive.
Due to poor planning and incapable management the production costs are too high.
In my estimate the labour costs to assemble a Global 7500 aircraft is same as A380.
Bombardier employees cannot do it right first time. Parts / assemblies are installed , removed, reinstalled on air crafts because workers lack the required skills.
Depends on government funding!!!
Regarding the Thunder Bay plant i feel the future is bleak. I'm already looking for my next job/career.
Regarding Bombardier as a whole I do not believe they will ever be a real force in industry being managed as they are.
