INJURIOUS FALSEHOOD IN CANADIAN LAW

Injurious falsehood (sometimes called malicious falsehood, slander of title, or slander of goods) is a common law tort protecting against false statements that economically harm a person’s property, business, or products. Unlike defamation, which focuses on injury to reputation, injurious falsehood concerns financial loss arising from untrue statements that disparage the ownership, quality, or integrity of assets. The action has deep historical roots, originating from early English common law and later recognized in Canada through cases such as Manitoba Free Press Co. v. Nagy, [1907] S.C.R. 340.

The tort evolved to cover both slander of title, false statements that question ownership of property, and slander of quality, which involves false claims about the nature or condition of goods or services. Together, these principles protect commercial and personal interests from dishonest competition and misleading disparagement.

HISTORICAL DEVELOPMENT AND PURPOSE

The earliest form of the tort, slander of title, appeared when property rights were essential to commerce. Over time, courts extended the principle to situations where false statements about goods or business operations caused measurable economic loss. The English decision in Ratcliffe v. Evans, [1892] 2 Q.B. 524, is a landmark case establishing liability where a false statement (though not defamatory) caused pecuniary harm. Canadian courts soon followed suit, grounding the modern concept of injurious falsehood in the protection of economic interests against deceit and malice.

This tort plays an important role in preventing unfair competition. Businesses rely on the truthfulness of commercial representations, and false disparagement can undermine market confidence. The law thus strikes a balance between protecting free expression and preserving fair dealing in trade.

ELEMENTS OF THE TORT

To succeed in a claim for injurious falsehood, the plaintiff must generally prove four elements:

  1. A false statement about the plaintiff’s goods, property, or business;

  2. Publication to a third party;

  3. Malice, meaning the statement was made dishonestly or with an improper motive; and

  4. Special damage, representing actual or anticipated financial loss.

Each element serves a distinct function in separating legitimate competition from wrongful conduct. Truthful comparisons or fair opinions remain lawful, while deliberate or reckless falsehoods attract liability.

Canadian courts emphasize that malice is essential. It can be inferred where a defendant knew a statement was false, acted with reckless disregard for its truth, or published it without a bona fide purpose. The decision in Manitoba Free Press Co. v. Nagy confirmed that reckless disregard for truth is sufficient evidence of malice.

In Ontario, section 17 of the Libel and Slander Act, R.S.O. 1990, c. L.12 modifies the common law by removing the need to prove special damages when written falsehoods are calculated to cause financial harm.

SLANDER OF TITLE

Slander of title arises where a person falsely asserts an adverse claim over another’s land, goods, or property interests, thereby discouraging potential buyers or tenants. This might include a fraudulent claim of ownership, an invalid lien, or the wrongful registration of a legal interest. The harm lies not in reputation but in the interference with the ability to transact.

Courts require proof that the statement was false, malicious, and resulted in financial loss. In Captain Developments Ltd. v. Nu-West Group Ltd., [1983] O.J. No. 3294 (Ont. C.A.), the Ontario Court of Appeal reaffirmed that registering a legal caution can amount to actionable conduct when done falsely and with malice.

However, good-faith legal filings, such as certificates of pending litigation or sworn affidavits, are absolutely privileged and cannot form the basis of a claim.

SLANDER OF QUALITY

Slander of quality involves false or misleading statements that discredit the quality, performance, or reliability of goods or services. For example, a competitor might spread a false rumour that a product is unsafe or defective. The case of Rust Check Canada v. Young (1988), 47 C.C.L.T. 279 (Ont. S.C.) illustrates that lawful comparative advertising becomes actionable only when the claim crosses the line into factual misrepresentation.

In this context, courts apply an objective standard, whether a reasonable person with knowledge of the facts would treat the claim as a serious allegation of defect or inferiority. Puffery and opinion are permitted, but deceitful disparagement is not.

ANALOGOUS SITUATIONS AND RELATED CLAIMS

The tort extends beyond tangible property. Courts have recognized injurious falsehood in cases where defendants falsely alleged that a company was going out of business, or that a party was engaged in fraud or patent infringement. These statements, though not personal defamation, inflict direct economic harm.

In First Choice Canadian Communications Corp. v. Terra Cable Ltd. (1993), 133 N.B.R. (2d) 115 (N.B.Q.B.), the court found liability where false statements about alleged fraud caused substantial business losses. Similarly, false assertions of ownership or patent rights can give rise to injurious falsehood claims when made maliciously and without justification.

PROVING DAMAGE AND RELIEF AVAILABLE

A claimant must show measurable loss caused by the falsehood—such as cancelled contracts, reduced sales, or decline in property value. While general loss of custom may suffice in some cases, courts often require specific evidence linking the false statement to the financial harm.

Remedies include damages for proven loss and, where appropriate, injunctive relief to prevent further dissemination of the false statements. In Church & Dwight v. Sifto Canada (1994), 22 C.C.L.T. (2d) 304 (Ont. Gen. Div.), the court granted an injunction where continued publication would likely cause additional loss.

DIFFERENCES FROM DEFAMATION

Although closely related, injurious falsehood differs from defamation in several key respects:

  • Subject matter: Defamation protects personal or professional reputation, while injurious falsehood protects property and economic interests.

  • Proof of falsity: The plaintiff must affirmatively prove falsity in injurious falsehood, whereas in defamation, falsity is presumed.

  • Requirement of malice and damage: Both must be proven; negligence is insufficient.

  • Type of loss: Injurious falsehood focuses on pecuniary harm, not emotional or reputational injury.

The two torts sometimes overlap, especially where false statements about goods or business practices also reflect on the person’s integrity. Courts analyze context carefully to determine which cause of action best fits.

STRATEGIC CONSIDERATIONS IN LITIGATION

Injurious falsehood claims often arise in commercial disputes, real estate conflicts, and competitive business contexts. Plaintiffs must gather strong evidence of both falsity and malice (i.e., emails, advertisements, or correspondence showing reckless disregard for truth can be important). Defendants, on the other hand, may rely on fair comment, honest opinion, or qualified privilege where applicable.

Because damages are often difficult to quantify, early legal advice is important. Counsel may recommend injunctive relief to prevent further dissemination while preserving the ability to seek damages later.

MODERN APPLICATIONS AND EMERGING CONTEXTS

In recent years, the tort of injurious falsehood has taken on renewed importance as false statements spread rapidly through digital platforms and online business directories. The ability of a single post, review, or video to disrupt a commercial relationship has forced courts to adapt long-standing principles to a modern information environment.

Canadian courts have recognized that the same common law elements apply online. When a competitor, former client, or anonymous user publishes false material claims about a business, such as alleging regulatory breaches, false ownership disputes, or product defects, the publication can give rise to liability if malice and economic loss are proven. Although the law still protects honest comment and fair competition, courts remain alert to deliberate campaigns that use misinformation to cause financial harm.

Online business defamation and injurious falsehood increasingly intersect. A misleading Google review, for example, may contain defamatory statements about the business owner and also false statements about the services provided. Each tort addresses a different aspect of the injury: one reputational, the other commercial. Legal counsel must assess both causes of action strategically to determine which offers the strongest remedy.

Where injurious falsehood involves corporate or professional services, the claims often arise alongside allegations of interference with economic relations or unlawful competition. For instance, where a rival falsely informs clients that a business lacks required licenses or is under investigation, the conduct may constitute both injurious falsehood and interference with contractual relations. The availability of concurrent causes of action allows courts to provide tailored relief according to the nature of the loss.

Injunctions remain a particularly useful tool in this area. Courts will restrain further publication where continuing falsehoods pose a real risk of ongoing harm. In doing so, judges balance the public interest in freedom of expression with the principle that commercial communication must not be dishonest. An injunction may be granted even before trial if there is compelling evidence of falsity and malice and where damages alone would not adequately compensate the plaintiff.

The development of this tort continues to reflect a broader principle in Canadian tort law: the protection of economic interests from intentional wrongdoing. Injurious falsehood reinforces market integrity by discouraging the misuse of speech for competitive advantage. It remains an essential safeguard for property owners, entrepreneurs, and professionals whose livelihood depends on public trust and accurate information.
