The courts.
If I can, Mr. Chairman, to help clarify, under subsection 17(9), it states:
In making a variation order varying a custody order, the court shall give effect to the principle that a child of the marriage should have as much contact with each former spouse as is consistent with the best interests of the child and, for that purpose, where the variation order would grant custody of the child to a person who does not currently have custody, the court shall take into consideration the willingness of that person to facilitate such contact.
That gives it both ways.
