Absolutely, there is stuff the government can do to both retain and retrain. The brain drain is something that has always been going on.
One of the things at this particular point in time that are perpetuating that are the programs that exist in other countries that could be redone. I think one of our witnesses talked this morning about continuity. These programs are particularly long term. They're very expensive and unique to this sector versus other sectors. Being able to have a program that allows employees to have certainty going forward in their companies, in their technologies and in the programs they participate in is really important.
Retraining and retention touch primarily on innovation and innovation support programs. We've heard multiple witnesses talk about the long term. Some of them are eight years long. The one we're in is five years long. Keeping an employee in uncertain times is difficult for a company to do on their own.
There is a silver lining. I think Christyn talked about this one. We're very thankful for defence procurement, because that's kept us alive. The commercial market completely disappeared on us, and we thank God for the defence sector because it kept us alive. Those things, leveraging those programs, will help us retain those employees.
On the retraining bit, I can't speak so much, but what I do know is that we're creating safety systems for autonomous vehicles that will ease somewhat the burden on air traffic controllers. It's not going to solve the issues that have been talked about this morning, but it should lessen the impact as we're now starting to introduce new things like drones into the airspace and have air traffic controllers deal with them as well as everything else.
I'll stop there, but those are two big themes that I would share with this committee on that question.
