The international lines are subject to federal regulation, depending upon the proponent's election. The proponent has the ability to run the project through a provincial permitting system rather than the federal permitting system, which is what happened in the MATL line, the Alberta-Montana intertie that you referred to.
You have this sort of strange combination of federal and provincial regulation, which seems odd to me. It's not what we do for pipelines. It's not clear to me why we have different rules for transmission lines.
