It is about coordination. We live in a country of co-operative federalism. That requires the provinces, the federal government and first nations be at the table to discuss and negotiate when jurisdictions overlap.
Unfortunately, if one of those parties chooses not to come to the table or refuses to enter into an agreement, that can, obviously, stall the negotiations and leave us in a deadlock or a stalemate.
That can't be allowed. We can't be frustrating first nations jurisdiction in those circumstances. It is inherent. It does come before other jurisdictions and should be given the force of federal law and therefore paramountcy over provincial laws when provincial governments refuse to enter into such coordination agreements.
