Definition

An injunction is a remedy by which the Court orders a party to do or refrain from doing a
particular act or thing.1
Origins & Evolution



An injunction is a form of equitable remedy that predates the fusion of law and equity
Like all equitable relief, injunctions developed to provide a remedy where the operation
of law would not do justice.
The question of whether the operation of law (as opposed to equity) will suffice is still
relevant. As discussed below, by requiring that the plaintiff show “irreparable harm,”
injunctions are not available where the ‘wrong’ at issue can be remedied by common law
remedies, namely damages:
“The very first principle of injunction law is that … you do not
obtain injunctions to restrain actionable wrongs for which damages
are the proper remedy.”2

However, Justice Sharpe has observed that in spite of the historic basis for injunctions,
“In deciding whether to grant injunctions, modern courts are less
and less willing to be bound by tradition alone, and more and more
willing to base their decisions on the relative advantages and
disadvantages of damages or an injunction… History and the
traditional hierarchy are replaced by principle and pragmatism. A
context specific determination of the advantages and disadvantages
of damages on the one hand and injunctive relief on the other
allows the court to select the remedy that best fits the right that is
to be protected or vindicated.”3


In Ontario, only the Superior Court of Justice may grant an injunction. The Superior
Court’s Jurisdiction is based on:
o its inherent jurisdiction; and
o s. 101 of the Courts of Justice Act:
Injunctions and Receivers
101(1) In the Superior Court of Justice, an interlocutory
injunction or mandatory order may be granted or a receiver
or receiver and manager may be appointed by an
interlocutory order, where it appears to a judge of the court
to be just or convenient to do so.
Terms
(2) An order under subsection (1) may include such terms
as are considered just.4

While not a court of inherent jurisdiction, the Federal Court may also grant an
interlocutory injunction as a function of its statutory authority to oversee the exercise of
power by federal administrative bodies.5
Purpose


Interlocutory injunctions were traditionally conceived of in terms of freezing the status
quo until a final determination of a dispute could be made. This raises some conceptual
and practical challenges:
o How to determine the status quo?
o In some circumstances, merely freezing the current state of affairs is not sufficient
to ensure that a court can do justice when it renders a final decision.
Accordingly, modern justifications focus more on the need to ensure that effective relief
can be rendered upon a final determination rather than simply freezing the current state of
affairs:
“The purpose of … an injunction is to improve the chances of the
court being able to do justice after the determination of the merits
at trial. At the interlocutory stage, the court must therefore assess
whether granting or withholding an injunction is more likely to
produce a just result.”6

-3Types


Injunctions can be prohibitive (that is, they forbid a party from doing a particular act or
thing),7 or mandatory (that is, they require a party to do a particular act or thing).8
In terms of their scope, injunctions can be interlocutory (that is, a pre-trial order put in
place until a final determination occurs) or permanent (that is, they take effect
indefinitely).
Procedure


The procedure for seeking an injunction is governed by Rule 40 of the Rules of Civil
Procedure.
Rule 40.01 provides that an injunction may be obtained on a motion to a judge:
How Obtained
40.01 An interlocutory injunction or mandatory order under
section 101 or 102 of the Courts of Justice Act may be obtained on
motion to a judge by a party to a pending or intended proceeding.9


The ordinary rules for motions therefore apply.
Ex parte motions (motions made without notice)
o in certain circumstances, it might be appropriate to bring a motion without notice,
such as where notice would defeat the purpose of the order sought
o moving party must make full and frank disclosure to ensure that the court is not
misled on the evidence. Failure to do so can be fatal to the motion.
The Guiding Dilemma

Ultimately, the court is faced with this dilemma: On the one hand, if an immediate
remedy in the form of an injunction is withheld, the plaintiff’s rights might be so
impaired by the time of a final determination that it would be impossible to fashion a
proper remedy. On the other hand, if an injunction is granted, the defendant might end up
having been restrained from engaging in conduct that ultimately turns out to be entirely
lawful.
The Test

Pursuant to Rule 40.01 of the Rules of Civil Procedure, a court may grant an
interlocutory injunction on such terms as are considered just. This requires the
application of a three-part test first formulated by the House of Lords in American
Cynamid Co. v. Ethicon Ltd. (“American Cynamid”)10 and adopted in Canada by the

-4Supreme Court of Canada (“SCC”) in RJR-MacDonald Inc. v. Canada (AG) (“RJRMacDonald”).11 The plaintiff bears the burden of proof at each stage.
1. Strength of the Plaintiff’s Case
o The plaintiff must show a “serious question [of fact or law] to be tried.”
Previously, plaintiffs had been required to show a “strong prima facie case.” The
“serious question to be tried” standard is generally a low threshold. In RJRMacDonald, the SCC held that:
“The threshold is a low one. The judge on the application
must make a preliminary assessment of the merits of the
case… Once satisfied that the application is neither
vexatious nor frivolous, the motions judge should proceed
to consider that the plaintiff is unlikely to succeed at trial.
A prolonged examination of the merits is neither necessary
nor desirable.”
o However, in certain contexts the plaintiff will be required to meet a higher
threshold more akin to the “strong prima facie case” requirement.12 These include
cases dealing with:
 Picketing
 Defamation
 Restrictive (negative) covenants
 Fiduciary duties and misuse of confidential information13
 Take-over bids
2. Whether the Plaintiff Will Suffer Irreparable Harm Without an Injunction
o An injunction is an extraordinary remedy because it restricts a person from acting
or requires them to do a particular act before there has been a final determination
as to whether the restriction or requirement is warranted.
o Accordingly, to justify such extraordinary relief, the plaintiff must show that,
absent an injunction, he or she would not be able to remedy the wrong through
normal legal proceedings, typically an action for damages:
“The notion of irreparable harm both incorporates and
substitutes for the traditional discretionary barrier to
equitable remedies; namely, proof that common law
equities are inadequate.”14

-5o In RJR-MacDonald, the SCC held that,
“Irreparable” refers to the nature of the harm suffered
rather than its magnitude. It is harm which either cannot be
quantified in monetary terms or cannot be cured, usually
because one party cannot collect damages from the other.
[Emphasis added]
o Examples of irreparable harm include:
 Harm to one’s reputation or career15
 Harm to the viability of a business, including goodwill16
 Non-compliance with a restrictive covenant17
 Infringements of natural resources or the quiet enjoyment of land18
 Intellectual property infringements19
o Generally, irreparable harm will not be inferred and requires evidence that is
“clear and not speculative.”20
o Likewise, a plaintiff may be refused an interlocutory injunction if there are
reasonable steps he or should could take to avoid the harm or ensure that any
harm suffered is not irreparable.21
Plaintiff’s Undertaking
o The plaintiff will normally be required to post an undertaking in damages to
provide for the event in which he or she ultimately abandons the claim or is
unsuccessful at trial. The undertaking aims to offset the risk to the defendant in
granting a remedy before the legality of the conduct complained of is ultimately
determined. Courts have required that the undertaking be “meaningful.” However,
the court may dispense with the undertaking altogether where the plaintiff has a
compelling case or does not have the financial means to make such an
undertaking.22
o In Ontario, Rule 40.03 of the Rules of Civil Procedure stipulates that:
Undertaking
40.03 On a motion for an interlocutory injunction or
mandatory order, the moving party shall, unless the court
orders otherwise, undertake to abide by any order

-6concerning damages that the court may make if it
ultimately appears that the granting of the order has caused
damage to the responding party for which the moving party
ought to compensate the responding party.23
o If the plaintiff is ultimately unsuccessful at trial, the defendant will be able to
claim damages for the harm suffered as a result of the improperly obtained
injunction.24
o The defendant may also be required to keep proper records so that the plaintiff
can quantify the amount owed as a result of an improper injunction.25
3. The Balance of Convenience
o If the plaintiff has shown that there is a serious issue to be tried and that, absent an
injunction, he or she would suffer irreparable harm, the court will consider the
relative impact of granting or denying an injunction on the parties
o This can involve any number of considerations. Common considerations include:
 Timing
 A plaintiff once entitled to an injunction might lose that right on
account of delay in asserting the claim.26
 Delay alone may not be fatal if the defendant has not been
prejudiced by the delay.27 However, if the plaintiff has delayed in
bringing the injunction, the court will be disinclined to find that the
harm complained of is truly “irreparable.”28
 Undertaking (discussed above)
 Third parties - i.e. the relative prejudice to third parties may also be
considered.29
The Merits of the Case: A Fourth Prerequisite?


By requiring a plaintiff only to meet the relatively low “serious question to be tried”
standard, the American Cynamid/RJR-Macdonald approach seemingly precludes any
substantive review of the merits of a case. This makes sense given that the court does not
have the benefits afforded by a full trial on a motion for an injunction.
However, in American Cynamid the House of Lords recognized a limited exception to
this prohibition at the end of the ‘balance of convenience’ step if an assessment of
irreparable harm and balance of convenience has not yielded a clear answer. This
approach has been adopted in Canada as well. As Justice Sharpe explains,

-7The core test to be applied is irreparable harm and the balance of
convenience. It is only where the irreparable harm and the balance
of convenience fail to yield a clear answer that the relative strength
of the parties’ cases may be taken into account, and even then, only
where one side of the case is clearly stronger…
…
It seems incontrovertible that the plaintiff’s chance of ultimate
success is directly relevant to an assessment of the relative risks of
harm. The likelihood of the plaintiff’s success or failure relates
both to the extent of the risk that there will be any legal harm
which calls for a remedy in favour of the plaintiff, and to the extent
of the risk that an injunction may prevent the defendant from
pursuing a rightful course of conduct.30
The Court’s Flexible Approach

A strict application of the RJR-MacDonald test does not always produce results that
reflect the overall balance of risk:
[A] box-ticking approach does not do justice to the complexity of a
decision as to whether or not to grant an interlocutory injunction.31

Accordingly, Canadian courts have opted for a flexible approach wherein the various
steps of the RJR-MacDonald test are viewed as guidelines rather than strict preconditions:
…the strength of the case, irreparable harm and balance of
convenience considerations, although prescribed and necessary
parts of the analysis mandated by the Supreme Court, are
nonetheless not usefully seen as an inflexible straightjacket.
Instead, they should be regarded as the framework in which a court
will assess whether an injunction is warranted in any particular
case. The ultimate focus of the court must always be on the justice
and equity of the situation in issue … there are important and
considerable interconnections between the three tests. They are not
watertight compartments.32

-8Practical Considerations
Plaintiff:






Drafting affidavits with the test and the defendant’s likely arguments in mind:
o Does the type of action fall into the limited exceptions for which the Court may
require satisfying a higher threshold akin to a “strong prima facie case”?
o Why is the harm irreparable? i.e. why will damages not suffice?
o Has the plaintiff moved quickly to bring the motion? Has the defendant been
prejudiced by the time between the conduct that is said to justify an injunction and
the bringing of legal proceedings?
o Is there anything that the plaintiff can reasonably do to mitigate the harm
complained of?
o Would it be harder on the plaintiff not to grant the injunction than the hardship
faced by the defendant if the injunction were granted?
o Is the plaintiff’s case likely to succeed at trial?
Undertaking as to damages:
o Can the plaintiff provide a meaningful undertaking in case he or she abandons the
action or is ultimately unsuccessful? If not, what is the basis for having the Court
employ its discretion to forego the undertaking?
Have to be able to move quickly
o To get in court quickly  Motions Scheduling Court to demonstrate the urgency,
or a 9:30 appointment on the Commercial List if the subject matter is commercial
Effectively running an application with witnesses
Costs – injunctions can be expensive
Is the injunction absolutely necessary, or can the harm be dealt with at trial? The plaintiff
bears the burden of proof at each stage of the RJR-MacDonald analysis and judges are
generally disinclined to order such an extraordinary remedy
Defendant:


Challenge of having to drop everything to respond quickly
o If you cannot drop everything to respond, or the client cannot afford for you to
respond, how to get an agreement that preserves the status quo?
o Getting an adjournment and on what terms?
Whether to file responding materials or just cross-examine the plaintiff’s affiants?
o If you begin cross-examining the plaintiff’s affiant without having filed a
responding affidavit, will not be able to file a responding affidavit without leave
of the court
o Responding affidavit would try to show:
 monetary nature of alleged harm (such that damages would suffice and
injunction is unwarranted)
 harm to defendant if injunction is granted
 ability of plaintiff to mitigate the harm
 delay
