The idea is to determine how the companies could be forced to make them available, which isn't a simple or easy matter. They can always argue that a potential mining project somewhere will be developed in 30 years.
To retain something, they have all the tricks of the trade and all the arguments. How could that be imposed on them? The AMT definitely couldn't do it; the Canadian Transportation Agency could look into it. We could make a request to determine whether the railway company is actually abusing the situation by not wanting to make a railway line available to us.
We didn't dare go that far when we reviewed the act. We thought that, as with anything, if we asked for too much, we'd lose everything we had.
Perhaps we should view this more as a matter of stages over time. There will definitely be another review of the act in five years. There will be another one five years later. Perhaps we can be more particular at that time, but, for the moment, we haven't felt the need to go further.
