The biggest mistake is treating urgency as a substitute for proof. Ontario’s procedural rules allow genuinely urgent injunction motions to move quickly, but urgency does not reduce the need for a sound legal basis, a credible evidentiary record, proper disclosure, and a carefully drafted order.
A matter can be extremely time-sensitive and still fail if the evidence does not establish the legal requirements for the relief requested.
Why is urgency alone not enough to obtain an injunction?
Urgency explains why the court is being asked to act quickly. It does not establish why the court should grant the injunction.
For a conventional interlocutory injunction that restrains conduct, the moving party ordinarily still needs to address the RJR—MacDonald framework: a serious question to be tried, irreparable harm, and the balance of convenience.
Where the requested order is mandatory in substance, the first-stage merits threshold may be more demanding.
The complete framework is explained in What do you have to prove to get an interlocutory injunction in Ontario?.
The practical point is simple: a compressed timetable changes the speed of preparation, not the substance that must ultimately be proved.
Why does the evidentiary record matter so much?
Injunction motions are highly dependent on the motion record.
The Superior Court of Justice may have to make an important interim decision before the parties have completed discoveries or reached trial. The moving party therefore needs affidavit evidence and supporting documents capable of establishing the relevant legal right, the threatened harm, the urgency, and the practical consequences of granting or refusing relief.
A weak factual record cannot ordinarily be repaired by repeatedly emphasizing that the matter is urgent.
Chronology is particularly important. The evidence should make clear what occurred, what is expected to happen next, when it may happen, and why court intervention is required before the ordinary litigation process can address the dispute.
See What evidence matters most on an injunction motion in Ontario? for the evidentiary considerations in more detail.
Why are without-notice motions especially demanding?
Where relief is sought without notice, urgency creates additional responsibilities rather than eliminating them.
Under Rule 39.01(6) of the Rules of Civil Procedure, the moving party must make full and fair disclosure of all material facts. That includes facts that may assist the responding party’s position, not only facts supporting the requested relief.
Failure to make the required disclosure may itself provide a basis for setting aside the order.
For the separate procedural requirements, see Can you get an injunction without notice to the other side in Ontario?.
Why does the wording of the proposed order matter?
An injunction should be drafted with enough precision that the affected party can understand what conduct is restrained or what action is required and the court can meaningfully supervise compliance.
An order that is unnecessarily broad, ambiguous, or disconnected from the evidence may create problems both at the injunction hearing and later if enforcement becomes necessary.
The objective is therefore not to request the broadest order imaginable. It is to identify the relief actually necessary to address the demonstrated risk.
What should be assessed before an urgent injunction motion is brought?
Preparation should address more than urgency.
Counsel should consider the applicable injunction test, the strength of the underlying legal claim, the affidavit and documentary record, the adequacy of damages, the proposed scope of relief, and the practical effect of the order on both sides.
The moving party should also consider the undertaking as to damages required by Rule 40.03, unless the court orders otherwise. Interim relief can create loss for the responding party, and that potential exposure is part of the strategic assessment before an injunction is sought.
How does ME Law approach an urgent injunction motion?
ME Law approaches urgency as a case-management constraint, not a substitute for legal preparation.
The objective is to identify the precise relief required, build the evidentiary record around the applicable test, address procedural obligations early, and draft an order that is sufficiently narrow and precise for the court to grant and supervise.
That includes assessing not only whether an injunction can be sought quickly, but whether the available evidence and legal theory justify asking the court to intervene before the underlying dispute has been finally determined.
