Yes, I'll comment in terms of the context, and then Michelle can go into some of the specifics.
As I mentioned earlier, while we're facing a very significant infrastructure build over the next 20 years, in the order of $300 billion, we as an industry built up our infrastructure a generation ago. So, many of the companies saw a significant reduction in their workforce from the early 1990s for a period of about a decade and a half.
We went through a period when there were very few, and, in some companies, no, apprentices moving forward, one, because of the infrastructure build they're looking at, and two, because of the generational change in staff. Apprenticeships are now probably one of the top if not the top issue for people in human resources within the companies. That's a significant change from where we were a decade ago, but it's a reflection of the infrastructure challenge we're facing.
