An injunction is an emergency court order that stops a party from taking a specific action—such as stealing clients, destroying evidence, or selling disputed assets. To obtain one in Ontario, you must satisfy the RJR-MacDonald test: a serious issue, irreparable harm, and a balance of convenience in your favour. Powell Litigation acts quickly to secure urgent relief in high-stakes business disputes across Toronto and the GTA.
In fast-moving commercial disputes, waiting even a few days can cause irreversible damage. Whether it is a departing employee misusing confidential information or a business partner diverting assets, injunctions are designed to preserve the status quo before the damage is done.

When Do You Need an Emergency Injunction?
An injunction is typically required when immediate action is necessary to prevent harm that cannot be undone.
Common scenarios include:
- A business partner siphoning company funds or assets
- A former employee using confidential information or trade secrets
- A competitor infringing on intellectual property or trademarks
- A shareholder attempting to sell or transfer disputed assets
These situations often arise in urgent commercial litigation across the GTA, where speed and precision are critical.
The 3-Part Legal Test for an Injunction (RJR-MacDonald)
To obtain an injunction in Ontario, you must satisfy the three-part legal test established in RJR-MacDonald.
- Serious Issue to Be Tried: The claim must be legitimate and not frivolous
- Irreparable Harm: The harm cannot be adequately compensated by money
- Balance of Convenience: The court weighs which party would suffer greater harm
Examples of irreparable harm include:
- Loss of business reputation or goodwill
- Permanent loss of market share
- Disclosure of confidential or proprietary information
- Dissipation of assets before judgment
The strength of your evidence at this early stage can determine whether the court grants urgent relief.
Beyond the Basics: Mareva Injunctions and Anton Piller Orders
Certain cases require extraordinary remedies beyond standard injunctions.
A Mareva injunction is an emergency court order in Ontario used to freeze a defendant’s assets to prevent them from being moved or hidden before a judgment is reached.
An Anton Piller order is a civil search warrant that allows the seizure of evidence to prevent its destruction.
These remedies are powerful but difficult to obtain. Courts require strict compliance with procedural safeguards and strong evidence of risk.
Why Full and Frank Disclosure Matters in Ex Parte Motions
When seeking an injunction without notice to the other party (ex parte), you have a legal duty to provide full and frank disclosure to the court.
This means you must disclose:
- All relevant facts, including those that weaken your case
- Any defenses the other side may raise
- Any gaps or uncertainties in your evidence
Failure to meet this duty can result in the injunction being set aside—even if it was initially granted.
Commercial List and Strategic Filing in Toronto
Complex business disputes in Toronto are often heard on the Commercial List, a specialized branch of the Ontario Superior Court of Justice designed for urgent and high-value cases.
Emergency motions are frequently brought at the 361 University Avenue courthouse, where timing, preparation, and procedural accuracy are critical.
Choosing the right venue and litigation strategy can significantly impact how quickly relief is granted.
Understanding the Risks: Undertaking as to Damages
To obtain an injunction, the applicant must provide an undertaking as to damages.
This means you agree to compensate the opposing party if the court later determines the injunction should not have been granted.
This requirement ensures fairness and underscores the importance of bringing injunction motions only when justified by strong evidence.
2026 Trends: Injunctions and Digital Assets
In 2026, Ontario courts are increasingly dealing with injunctions involving digital assets, including cryptocurrency and online business platforms.
These cases often involve rapid asset movement and require immediate legal intervention to prevent dissipation or concealment.
Modern commercial litigation demands a strategy that accounts for both traditional and digital asset risks.
Related Business Disputes
In many cases, injunctions arise alongside shareholder disputes, including oppression claims where majority stakeholders attempt to misuse company assets or exclude minority owners.
Urgent court intervention may be required to prevent further harm while the dispute is resolved.
Common Questions About Injunctions in Ontario
How fast can you get an injunction in Ontario?
In urgent cases, injunctions can be obtained within days or even hours, depending on the circumstances and the strength of the evidence.
What qualifies as irreparable harm?
Irreparable harm includes damage that cannot be easily quantified in money, such as loss of goodwill, confidential information, or market position.
Can you get an injunction without notifying the other party?
Yes. Courts may grant injunctions without notice in urgent situations, but strict disclosure obligations apply and the order is typically temporary.
