I'll try to answer this very succinctly.
The NRC has 14 research centres that occupy those 22 sites across the country. We are divided into engineering divisions that have a very applied focus, that have very strong connections with industry and in many cases are working directly with industry sectors. That might cover automotive, aerospace, construction as you've already mentioned, and others.
We have life science institutes that are focused on a range of things, from medical devices to ag biotech to human health. We have research centres focused on emerging technologies, which would cover advanced materials and photonics, and so now this is where astronomy comes in.
It's really important to recognize that although on the surface it looks like our astronomy group is doing very academic work, what we actually do is enable academics to gain access to world-class telescopes where Canada has some ownership. In fact, the majority of what we do is actually engineering, building next-generation instrumentation for emerging observatories, and of course we have observational astronomers who work hand in hand with academics.
Since you mentioned DRAO, you will also know that CHIME, which is a university-owned facility, is hosted on the DRAO site, and there's a very strong collaboration with NRC.
That's a very high level, but of course we're very happy to send to the chair a more detailed overview of NRC's structure and operations.
