The best way to do it, we've found, is go directly to the purchasers of construction—the Suncors, the Shells, the CNRLs—and tell them when they make arrangements with their contractors to make it part of the contractual obligation between an energy company and a construction company that, if that company is a contractor of Suncor or of CNRL, it must do x, y, z and have an engagement plan.
We work really hard on the work sites to implement that kind of change. It's slow, but there are really good examples, and I could provide those examples to the committee in writing afterwards.
