3.
1. (a) The court shall grant a request for termination of a sentence of probation under this section when, having regard to the conduct and condition of the probationer, the court is of the opinion that:
  1. (i) the probationer is no longer in need of such guidance, training or other assistance which would otherwise be administered through probation supervision;
