Whether the NEB is left in Calgary or moved back to Ottawa is essentially a political decision.  It was originally moved from Ottawa to Calgary in 1991 largely for national unity reasons.  Reasons can be found to justify the choice of either city.  However, it would be a mistake to relocate the board members without their staff.  Expert economic regulatory tribunals are most successful when there are solid working relationships between board members and expert staff.  Relocating the decision-makers without the ease of access to expert staff that co-location provides could hamper the ability of board members to discharge their office.  Either leave it all in Calgary or return all of it to Ottawa.
