Can a party get an emergency exclusive possession order the same day violence is alleged?

It's possible in a genuinely urgent situation, but it isn't guaranteed or routine — Ontario family courts can hear an urgent motion for exclusive possession of the matrimonial home quickly, sometimes without notice to the other party, where the evidence shows a real and immediate safety concern, but there's no fixed rule that any such motion will be heard on the very day it's brought. How quickly it actually gets before a judge depends on the courthouse, the strength and clarity of the supporting evidence, and how the urgency is presented to the court.

Because an urgent, without-notice application is a significant step, the party bringing it needs to provide a clear, honest account of the situation and why it can't wait for the normal process, since orders granted this way are subject to review once the other party is served and has a chance to respond. Anyone facing this kind of emergency should contact a family lawyer immediately, since properly preparing the supporting material has a real effect on how the court responds.
