PCL, for example, provides unionized commercial institutional work across the country. I think it's the seventh-biggest contractor in the country. It does all its work with the building trades in Ontario and does its industrial work with the building trades in the west, with the exception of its spinoff, Monad, which I think is with the Christian Labour Association. There are EllisDon, Aecon, Bechtel, Fluor, Black & McDonald, Comstock, Kiewit. The list goes on and on.
There are literally 500 significant contractors that are at the top of the pyramid. Then there are another thousand contractors, slightly smaller than that, who do it regionally. Then there are another couple thousand contractors who do it locally.
