The best way to answer this question is in the context of an issue that hasn't been touched on but I think is central to the development of the oil sands, and that has to do with pace.
Until this point, projects have proceeded whenever the energy companies developing them have requested it. So they participate in a land sell, they make an application for development, and they're almost always approved. There's no regulation of pace or one after the other.
Our former premier Peter Lougheed suggested that to manage development both in terms of the environment and the economy, it might make better sense to approve only one major project at a time. That hasn't happened.
It's almost like those old Three Stooges movies where all the stooges get caught in the door because they're trying to go through at the same time.
