Claims Particularly Relevant to PIC Readers - Article #17 | Primary search phrase: defamation libel slander Canada

Defamation, libel and slander in Canada concern communications that may harm a person’s reputation. The law protects reputation while respecting freedom of expression and legitimate public discussion. Most provinces and territories use common-law defamation principles, often alongside legislation, while Quebec uses a civil-law framework. Whether a statement is legally defamatory depends on its words, context, audience, publication, defences and jurisdiction.

What defamation means

Defamation is the broad legal concept. In common-law Canada, a plaintiff generally begins by proving three things: the words were communicated to at least one person other than the plaintiff; the words referred to the plaintiff; and the words would tend to lower the plaintiff’s reputation in the eyes of a reasonable person. The Supreme Court of Canada has repeatedly described this as the basic test.

The court considers the meaning an ordinary reasonable reader, listener or viewer would take from the communication in context. A statement does not have to use a person’s name if the surrounding circumstances make the person identifiable. Insults, criticism and unpleasant statements are not automatically defamatory; the legal question is whether the communication carries a reputation-lowering meaning and whether the other required elements are present.

Libel and slander: what is the difference?

Term

General common-law meaning

Examples

Defamation

The umbrella term for legally actionable harm to reputation through communication.

A written post, spoken statement, broadcast or other communication may potentially be defamatory.

Libel

Traditionally, defamation in writing or another relatively permanent form. Statutes may treat broadcasts as libel.

Articles, letters, social-media posts, emails, images, recordings or broadcasts, depending on the jurisdiction.

Slander

Traditionally, spoken or other more transient defamation.

Oral remarks in a conversation, meeting or speech.

The historical distinction can still matter because rules about damages, pleading and legislation may differ. It should not be assumed that every province or territory treats libel and slander identically. For example, Ontario’s Libel and Slander Act contains special rules for newspaper and broadcast libel, while British Columbia has its own Libel and Slander Act.

Important distinction

This article concerns civil defamation. The Criminal Code also contains offences dealing with defamatory libel. A civil claim for damage to reputation and a Criminal Code allegation are different legal processes with different elements, procedures and consequences.

Publication means communication to someone else

In common-law defamation, “publication” does not necessarily mean publication in a newspaper or on a public website. It generally means that the words were communicated to at least one person other than the person allegedly defamed. A private email copied to another person, a group message, a social-media post or an oral statement to a third party can potentially satisfy this requirement.

Internet publication creates additional questions. In Crookes v. Newton, the Supreme Court of Canada held that creating a hyperlink to defamatory material does not, by itself, amount to publishing the defamatory words. The result can be different if the linking communication itself repeats or adopts the defamatory content.

Allegations, repetition and court proceedings

Repeating an allegation can create legal risk even when the speaker identifies another person as the source. In Grant v. Torstar Corp., the Supreme Court described the “repetition rule”: generally, repeating a libel carries the same legal consequences as originating it. Simply saying “someone else alleged this” does not automatically protect the repetition.

Court-related reporting requires particular care. Canadian law recognizes privilege for some fair and accurate reports of public judicial proceedings, and provincial statutes may add protections. An allegation in a demand letter, unfiled pleading or anticipated case is not a proven fact and is not automatically privileged merely because litigation is contemplated. Protection depends on the occasion, jurisdiction and communication.

Common defences in common-law Canada

Once the plaintiff establishes the required elements of common-law defamation, the analysis may turn to one or more defences. The availability and requirements of a defence depend on the facts and jurisdiction.

Defence

General educational description

Truth / justification

Substantial truth can provide a complete defence to a common-law defamation claim. The legal burden and what must be proved should be checked under the applicable law.

Fair comment

Protects certain recognizable opinions on matters of public interest when they are based on facts and satisfy the legal test. The defence can be defeated by malice.

Responsible communication

May protect defamatory statements of fact on matters of public interest where the publisher acted responsibly and was diligent in trying to verify the allegations. It is not limited to professional journalists.

Absolute privilege

Certain occasions receive very strong protection, including statements made in particular judicial or legislative settings. The scope is defined by law.

Qualified privilege

Can protect communications made on an occasion where the maker has a duty or interest to communicate and the recipient has a corresponding interest in receiving the information. Malice or exceeding the occasion can defeat the defence.

Fair comment and responsible communication

The Supreme Court’s decision in WIC Radio Ltd. v. Simpson explains the defence of fair comment. The communication must be recognizable as comment rather than a statement of fact, relate to a matter of public interest, and have a factual foundation that supports the opinion. The test permits strong or unpopular opinions, but the defence may fail where the legal requirements are not met or where malice is proved.

Grant v. Torstar Corp. created the defence of responsible communication on matters of public interest. It considers whether the subject is genuinely of public interest and whether the publisher acted responsibly, including the seriousness of the allegation, urgency, source reliability, verification efforts, whether the affected person was asked for their side, and whether publication was justified. The defence is not limited to traditional news organizations.

Online posts, reviews and social media

Online communications can be copied, reposted or viewed across borders. Posts, reviews, video captions and group messages can potentially be defamatory if the legal requirements are met. Internet cases can also raise questions about where a claim should be heard and which law applies. Haaretz.com v. Goldhar considered jurisdiction and forum issues in an online defamation claim.

Deleting or editing a post does not necessarily erase evidence that it existed. Screenshots, platform records, messages and third-party copies may remain. Reposting, quoting or amplifying another person’s allegation can also raise separate publication issues.

Quebec uses a different legal framework

Quebec does not apply the common-law tort in the same way. The Civil Code of Quebec protects reputation and privacy, and defamation falls under general civil liability. In Bou Malhab v. Diffusion Metromedia CMR inc., the Supreme Court explained that a plaintiff must establish fault, injury and causation, with reputational injury assessed objectively.

Because the Quebec analysis is structurally different, common-law language about presumed falsity, justification or the technical libel/slander distinction should not be treated as a complete statement of Quebec law.

Damages and other possible remedies

A successful defamation claim may result in damages for reputational and related injury. Depending on the jurisdiction and facts, aggravated or punitive damages may be available in exceptional cases, and apologies, retractions, injunctions or other relief may be relevant. Hill v. Church of Scientology of Toronto discusses reputation and damages in a serious libel case.

The outcome is highly fact-specific. A defamatory publication does not guarantee a particular damages award, and the existence of a defence may defeat liability entirely.

Limitation periods and special notice rules

Defamation deadlines can be unusually short and jurisdiction-specific. Provincial legislation may create special rules for media claims. Ontario, for example, generally requires written notice within six weeks for certain newspaper or broadcast libel claims and provides a three-month limitation period, subject to the Act’s scope and conditions. Other claims may follow different limitation rules.

Because deadlines can depend on the medium, location, defendant and date of knowledge, jurisdiction-specific legal advice may be important rather than assuming the ordinary civil limitation period applies.

Important educational considerations

• An allegation is not the same as a proven fact, finding or conviction.
• Repeating another person’s accusation can create separate publication issues.
• Truth, opinion and public interest are legally distinct concepts and should not be used interchangeably.
• Privilege depends on the occasion and can have strict limits.
• Online publication can create jurisdiction and evidence issues across borders.
• Libel, slander, limitation periods and statutory protections vary by province and territory.
• Quebec applies a civil-law framework that differs from the common-law tort used elsewhere in Canada.

General practical steps for organizing information

Without assessing whether a claim or defence exists, a person trying to understand a possible defamation issue can generally organize information by:

• preserving the exact words, images or recording rather than relying only on memory;
• recording the date, platform or location and known audience;
• saving screenshots, URLs, message headers and relevant surrounding context;
• distinguishing the original statement from later repetitions or reposts;
• noting any correction, retraction, apology or request for clarification;
• identifying the province, territory or country connected to the publication and the people involved; and
• checking applicable defamation statutes, limitation rules and current court decisions before taking legal steps.

Emotional and family impact

Reputational disputes can be stressful, particularly where statements concern employment, family relationships, community standing or alleged misconduct. Online material may remain searchable or be repeatedly shared. Organized records, fewer unnecessary public exchanges and appropriate personal support may help while legal questions are assessed.

When professional assistance may be appropriate

Defamation law can be complex where allegations are serious, publication crosses jurisdictions, a media notice deadline may apply, privilege is asserted, or statements relate to another legal proceeding. A qualified lawyer can assess the applicable law, defences, deadlines, jurisdiction and remedies. Limited-scope services may sometimes be available.

How Presumption of Innocence Canada may help

Presumption of Innocence Canada provides general public legal education about Canadian legal processes and moderated discussion groups for educational discussion.

Frequently Asked Questions

What is the difference between defamation, libel and slander in Canada? Defamation is the broad concept. In common-law jurisdictions, libel generally refers to written or otherwise permanent defamation, while slander generally refers to spoken or transient defamation. Statutes and Quebec civil law can modify or replace those distinctions.

What must a plaintiff prove in a common-law defamation case? Generally, that the words were published to at least one person other than the plaintiff, referred to the plaintiff, and would tend to lower the plaintiff’s reputation in the eyes of a reasonable person.

Is a false accusation automatically defamation? No. The legal test also considers publication, identification, defamatory meaning, available defences, privilege and the law of the jurisdiction. The court must assess the complete context.

Can I be liable for repeating something someone else said? Potentially. The general repetition rule means attribution to another source does not automatically prevent liability for republication.

Is an opinion protected from defamation claims? Not automatically. The defence of fair comment has specific requirements, including a factual foundation, recognizable comment and a matter of public interest.

Can responsible communication protect an online publisher? Potentially. The Supreme Court has said the defence is available to anyone publishing public-interest material in any medium if the legal requirements, including responsible verification, are met.

Is linking to another website considered publication? A hyperlink alone is not ordinarily publication of the linked defamatory material under Crookes v. Newton. Repeating, endorsing or adopting the words can raise a different issue.

Are defamation deadlines shorter than other civil claims? Sometimes. Some provincial statutes impose special notice and limitation periods for particular media publications. The applicable jurisdiction and medium should be checked promptly.

Does Quebec use the same defamation test as Ontario or British Columbia? No. Quebec defamation is governed through the Civil Code’s general civil-liability framework, including fault, injury and causation, together with protection of reputation and freedom of expression.

Conclusion

Understanding defamation, libel and slander in Canada requires more than asking whether words were harsh or damaging. The analysis depends on publication, identification, defamatory meaning, context, defences, privilege, remedies and jurisdiction. Canadian law balances reputation with freedom of expression, while Quebec uses a different civil-law framework. Real disputes require verification of the applicable provincial or territorial law and deadlines.
