I don't know how the contractual arrangements with the specific brokerages are made; however, I can speak to a lot of the engagements I've had with the UA and others who have had similar situations to what you describe with the ironworkers.
Although workers who are in the trades move from site to site, oftentimes there is that mobility that needs to occur. They might move from, say, the Kearl site, but there's certainly another job ticket waiting at another site. I'd really like to follow up with you to understand more about this situation, because that's how I understand the process works, at least in the case of the UA.
Overall, when we talk to our building trades colleagues, they reinforce to us that there is a skilled labour shortage. In fact, the UA, again, is one of the biggest groups bringing in foreign workers from the United States. They've even developed their own system with a travel card, where if you have a certain card in the United States, you can come to Canada, to Alberta specifically, quite easily. That is purely as a result of our skilled trades shortage.
So I think there are some wrinkles in the system, and I'd like to delve into this particular issue. But there is a skilled trades shortage, and we do need access to foreign workers.
