(b) order that a claim or question stated in the third party notice be tried in such manner as it directs;

(c) give the third party leave to defend the proceeding, either alone or jointly with a defendant, or to attend and take part at the trial; and

(d) generally make such orders and give such directions as are necessary to ensure that all questions in the proceeding are effectually and completely determined and adjudicated on and as to the extent to which the third party is to be bound by a judgment or decision in the proceeding.

(2) The Court may make an order or give a direction under subrule (1) either before or after a judgment in the proceeding has been entered or given for the plaintiff against the defendant and may, at any time, vary or rescind such an order or direction.
