Bombardier is a Canadian technological corporation which if not financially aided now could result in further shrinking of the aerospace industry in the country going forward. Financially aiding the industry in difficult times could lead to a growth both in terms of employment and further research and development in this field in the future. Bombardier is being aided for the "potential" it holds. 

Airbus has done the same 30 odd years ago, and now look at how well the company is performing now.
