When making the decision, the federal minister has to take provincial policies into account. It's in the act. I'm not within the federal government, but from what I understand, the people within the investment review division at Industry Canada seek the views of their counterparts in relevant provincial departments. For example, if it's an energy deal, they might speak to the energy department in the Province of Alberta. There's already that consultation.
Do I think there should be joint decision-making by the provinces in which the assets are located and the federal government? I think it's a federal government jurisdictional issue, although I've heard arguments about the provinces having power over energy resources, natural resources, etc.
