On the environmental side, I'm not aware of the clause. I've focused specifically on labour, so I can't touch on the environmental side.
Obviously, raising standards for labour workers across the globe is important to us. At the same time, I think we look at the standards we try to set. You mentioned bringing workers over to different countries through SNC-Lavalin or those types of things. As Chris mentioned, typically those contractors, even if a large general was going to do work for SNC-Lavalin, they would bring maybe a general foreman or a supervisor over the whole project and then come there, but they would be under the standards of that individual country, obviously, not Canadian standards.
