1. Legal Framework of Defamation in Canada

To succeed in a defamation claim in Canada, a plaintiff must prove:

1. The impugned words were published (communicated to at least one person other than the plaintiff)
2. The words referred to the plaintiff
3. The words were defamatory, meaning they would lower the plaintiff’s reputation in the eyes of a reasonable person

Once these are proven, falsity and damages are presumed, and the burden shifts to the defendant to raise a defense.

2. Why Online Defamation is Different

Internet defamation raises additional legal issues:

• Global publication (jurisdiction disputes)
• Anonymity of posters
• Rapid and permanent dissemination
• Liability of intermediaries (platforms, ISPs, websites)
• Difficulty in enforcing judgments

Canadian courts have adapted defamation law through precedent rather than legislation.

3. Key Defenses in Canadian Defamation Law

Common defenses include:

• Truth (Justification)
• Fair comment / Honest opinion
• Responsible communication on matters of public interest
• Privilege (absolute or qualified)
• Innocent dissemination (limited for intermediaries)

4. Important Case Laws on Online Defamation in Canada

1. Grant v Torstar Corp, 2009 SCC 61

Significance: Established the “responsible communication on matters of public interest” defense.

• Expanded protection for journalists and online publishers.
• Even if statements are false, liability may be avoided if publication was responsible and in the public interest.
• Applied broadly to blogs, forums, and online journalism.

👉 This case modernized Canadian defamation law for the internet age.

2. Crookes v Newton, 2011 SCC 47

Significance: Defined liability for hyperlinking.

• The Supreme Court held that posting a hyperlink is not publication of the content it links to.
• Liability arises only if the hyperlinker adopts or repeats the content.

👉 This is foundational for online speech and blogging platforms.

3. A.B. v Bragg Communications Inc., 2012 SCC 46

Significance: Anonymous online defamation and privacy protection.

• Concerned a teen victim of cyberbullying seeking identity of anonymous posters.
• Court allowed anonymity to be lifted with limited disclosure.
• Balanced privacy rights vs. freedom of expression.

👉 Established the principle that courts may unmask anonymous online defamers where justified.

4. Barrick Gold Corp. v Lopehandia, 2004 CanLII 12938 (ON CA)

Significance: Landmark internet defamation case.

• False allegations posted online caused global reputational harm.
• Court emphasized that internet defamation is “ubiquitous and borderless”, increasing damages.
• Awarded significant damages due to viral online spread.

👉 One of the earliest Canadian cases recognizing the seriousness of online defamation.

5. Baglow v Smith, 2015 ONCA 407

Significance: Political blogging and freedom of expression.

• Concerned defamatory statements made in political online commentary.
• Court emphasized context matters, especially in political debate.
• Reinforced that online discourse is often robust and exaggerated.

👉 Demonstrates courts’ reluctance to restrict political online speech too easily.

6. Warman v Fournier, 2012 ONSC 2126

Significance: Twitter and social media defamation.

• Case involved defamatory tweets between political commentators.
• Court recognized Twitter as a platform for publication.
• Injunctions were considered, but courts are cautious due to free expression concerns.

👉 One of the earliest Canadian cases dealing directly with Twitter defamation.

7. Goldhar v Haaretz.com, 2018 SCC 28

Significance: Jurisdiction in online defamation.

• Israeli newspaper article defamed a Canadian businessman.
• Supreme Court addressed where a defamation case should be heard.
• Held that courts must balance:
  • Plaintiff’s connection to forum
  • Defendant’s freedom of expression
  • Where harm occurred

👉 Key ruling on cross-border internet defamation disputes.

5. Additional Legal Developments in Online Defamation

(A) Jurisdiction Issues

Canadian courts may hear cases if:

• Harm occurred in Canada
• Plaintiff resides in Canada
• Content was accessed in Canada

However, courts may decline jurisdiction if another forum is more appropriate (forum non conveniens principle).

(B) Anonymous Defendants

Courts may issue:

• Norwich orders (to force ISPs to disclose identities)
• Orders under privacy and procedural rules

Case example:

• A.B. v Bragg Communications (identity disclosure allowed with safeguards)

(C) Liability of Platforms

Generally:

• Platforms are not liable as publishers unless they actively contribute or refuse to remove content after notice in certain circumstances.
• Canada does not yet have strict statutory “notice-and-takedown” liability like some jurisdictions.

(D) Damages in Online Defamation

Courts consider:

• Extent of publication (viral spread increases damages)
• Seriousness of allegations
• Malice
• Reputational harm

Online defamation often leads to higher damages due to permanence and reach (Barrick Gold v Lopehandia).

6. Remedies Available

A plaintiff may seek:

• Monetary damages (general, special, aggravated, punitive)
• Injunctions to remove content
• Orders to identify anonymous defendants
• Retractions or corrections (rarely ordered but possible)

Conclusion

Online defamation litigation in Canada is a rapidly evolving area of law that balances two competing values:

• Protection of reputation
• Protection of freedom of expression under the Canadian Charter of Rights and Freedoms

Through key decisions like Grant v Torstar, Crookes v Newton, and Goldhar v Haaretz, Canadian courts have built a modern framework that adapts traditional defamation principles to the realities of the internet.
