Not every legal dispute can wait for a full trial to reach a resolution. When someone threatens action that causes immediate, irreversible damage, money alone cannot fix the problem. Learning how to get an injunction in Ontario allows businesses and individuals to stop harmful conduct before permanent loss occurs. This comprehensive legal guide explains the definition of an injunction, the primary categories available, and the criteria applied by courts across the province.

What Is an Injunction in Ontario Court Proceedings?

An injunction serves as an equitable court remedy. Rather than granting monetary compensation after damage takes place, the order directly commands a party to act or refrain from acting. Under Section 101 of the Courts of Justice Act, the Ontario Superior Court of Justice can grant an injunction whenever it appears just or convenient. Within active civil litigation matters, parties obtain an interlocutory injunction by bringing a formal motion under Rule 40 of the Rules of Civil Procedure.

Understanding the Primary Types of Injunctions

Ontario courts categorize injunctions in two primary ways based on timing and exact requirements:
  • By Timing: An interim injunction provides short-term protection, frequently granted during emergency situations without advance notice. An interlocutory injunction remains active until trial. A permanent injunction forms part of the final court judgment.
  • By Requirement: Prohibitory injunctions restrain a party from taking specific actions, such as breaching non-solicitation covenants or terminating commercial leases. Mandatory injunctions require positive acts, such as restoring property access. Because mandatory orders compel positive conduct, judges apply higher standards before granting them.

The Legal Test for Obtaining an Injunction

For most interlocutory injunctions, judges follow the three-part test set by the Supreme Court of Canada in RJR-MacDonald Inc. v. Canada (Attorney General). Moving parties must successfully establish every branch:
  • Serious Issue to Be Tried: The applicant must demonstrate a genuine, legitimate question. This initial threshold remains low, requiring only that the underlying claim is neither frivolous nor vexatious.
  • Irreparable Harm: The applicant must prove that damages cannot properly compensate the financial or operational injury if relief is denied. Classic examples include losing goodwill, client bases, or unique commercial locations.
  • Balance of Convenience: Courts evaluate which side suffers greater harm from granting or refusing the requested order pending trial.
Judges weigh these elements together to determine what result achieves justice.

Higher Legal Standards for Mandatory Injunctions

When an applicant seeks a mandatory order compelling active steps, the legal standard increases significantly. Following R. v. Canadian Broadcasting Corp., the Supreme Court of Canada established that applicants must demonstrate a strong prima facie case. This means proving a strong likelihood of ultimate success at trial rather than merely establishing a serious issue. Ontario courts analyze the practical effect of the requested order to decide if it is mandatory.

The Undertaking as to Damages Requirement

Under Rule 40.03 of the Rules of Civil Procedure, an applicant seeking an interlocutory injunction must offer an undertaking as to damages. This formal commitment promises to pay any damages the responding party suffers if the court later determines the injunction was improperly granted. Although judges hold discretion to dispense with this rule, applicants should prepare to provide financial undertakings.

Acting Quickly in Urgent Legal Disputes

Urgency remains essential when seeking emergency court relief. Injunction applications rely on meticulous affidavit evidence prepared on tight schedules. Unnecessary delays undermine claims of immediate urgency and irreparable harm. Anyone facing unlawful lockouts, stolen trade secrets, or asset dissipation should consult legal counsel immediately.

Frequently Asked Questions

What is the main difference between an interim and interlocutory injunction?

An interim injunction provides brief, immediate relief during urgent emergencies. An interlocutory injunction stays in effect continuously until the full trial finishes.

Can you get an injunction without notifying the other party?

Yes, courts grant ex parte interim injunctions without notice during extreme emergencies. However, the applicant must demonstrate that giving advance notice would cause immediate, severe harm.

What qualifies as irreparable harm in Ontario courts?

Irreparable harm refers to injury that money or damages cannot fix. Common examples include losing trade secrets, commercial reputation, unique real estate, or client relationships.

What happens if someone violates a court injunction?

Violating an injunction constitutes contempt of court. Judges enforce compliance through severe penalties, including substantial fines, asset seizures, or imprisonment.

Is an undertaking as to damages mandatory in every case?

Courts expect undertakings as to damages for interlocutory injunctions under Rule 40.03. However, judges retain discretion to waive the requirement under exceptional circumstances.

How long does it take to obtain an emergency injunction?

Emergency injunctions can be prepared and argued within hours or days when severe harm threatens. Standard interlocutory motions usually require several weeks to schedule.
