In the digital age, where information spreads rapidly through social media, online reviews, and word-of-mouth, maintaining a positive reputation for your business is more important than ever. However, negative or false statements about your business can quickly damage its public image, customer trust, and bottom line. This is where understanding defamation laws in Ontario comes into play.
Defamation law in Ontario exists to protect individuals and businesses from false statements that harm their reputation. In this blog, we will explore how defamation laws work in Ontario, what constitutes defamation, how businesses can protect themselves, and the steps to take if defamation occurs.

What is Defamation?

Defamation is the act of making false statements about a person or business that damages their reputation. Defamation laws are designed to protect individuals and businesses from the harm caused by false statements that could result in a loss of reputation, business, or social standing.
Defamation can occur in two main forms:

  • Slander:

    Defamation through spoken words or gestures.

  • Libel:

    Defamation through written or published statements, including online content.

In Ontario, defamation is considered both a civil wrong (tort) and, in some cases, a criminal act. It is generally easier to prove a civil defamation claim in a court of law than a criminal one, as the civil process focuses on compensating the victim for damages caused by the false statements.

Elements of Defamation in Ontario

To prove defamation in Ontario, certain elements must be established. These elements apply to both slander and libel cases:

  1. False Statement:

    The statement must be false. If the statement is true, it cannot be considered defamatory, even if it causes harm to your business. Truth is an absolute defense in defamation cases.

  2. Published or Communicated to Third Parties:

    The defamatory statement must have been communicated or published to a third party (someone other than the person being defamed). This could be through social media, news articles, online reviews, or conversations with others.

  3. Harm to Reputation:

    The statement must be harmful to the reputation of the person or business, such as causing financial loss, damage to customer trust, or harming public perception. In the context of a business, this could include lost sales, damaged brand value, or reduced employee morale in some circumstances the court will presume that the damages have occurred without the need to prove actual losses “damages at large”.

  4. Identification of the Business or Person:

    The statement must be reasonably understood as referring to the business or person being defamed. In the case of a business, it must be clear that the statement was about that business and not about another entity.

What Are Defenses Against Defamation?

In Ontario, several legal defenses can be used to protect individuals or businesses from defamation claims. Some of the most common defenses include:

  1. Truth (Justification):

    As mentioned, if the statement is true, it cannot be considered defamatory. The defendant must prove that the statement is accurate. This is an absolute defense.

  2. Opinion:

    A statement that expresses an opinion, as opposed to a false fact, may be protected under defamation laws. However, if an opinion is presented as a fact, it may still be considered defamatory.

  3. Privilege:

    Certain statements made in specific situations are considered privileged and are not subject to defamation claims. For example, statements made in parliamentary debates or judicial proceedings may be protected under absolute or qualified privilege.

  4. Fair Comment:
    This defense applies when the statement is an honest expression of opinion based on facts that are known to the public. It must be a fair comment on matters of public interest. For example, if someone expresses an opinion in a manner that is not malicious or based on false information.

How Can Businesses Protect Their Reputation in Ontario?


Preventing defamation from occurring in the first place is the best way to protect your business's reputation. Below are some steps businesses can take to mitigate the risk of defamation:

1. Monitor Your Online Presence


In today’s digital age, much of the defamation businesses face happens online. Regularly monitoring your business’s online presence on review websites, social media platforms, and other digital forums is essential. This will help identify any potentially defamatory content early on and allow you to address it quickly.

2. Respond to Negative Reviews and Comments Professionally


If you encounter negative reviews or comments that are based on false information, respond in a professional and manner. Clearly present facts that can dispel misinformation. Ask for a correction to any inaccuracies, and if necessary, request the removal of false statements.

3. Utilize Non-Disclosure and Confidentiality Agreements


For businesses that work with sensitive information or have agreements with employees, contractors, or suppliers, confidentiality agreements can be helpful in preventing defamatory statements. Non-disclosure agreements (NDAs) protect your business’s confidential information from being shared publicly or used maliciously.

4. Educate Employees and Partners


Educate your employees, contractors, and business partners about the potential consequences of defamation. Encourage them to be mindful of their words and actions, especially in public forums or online spaces. This is particularly important in industries where negative publicity can spread quickly.

5. Consult Legal Counsel


If your business has been defamed or you believe defamatory statements may harm your reputation, consult with a lawyer who specializes in defamation law. A lawyer can guide you on how to proceed with potential legal action, whether through a defamation lawsuit or by issuing a cease-and-desist letter to the individual or organization responsible for the defamation.

What to Do if Defamation Occurs


If you believe that your business has been defamed, there are several steps you can take:

  1. Document the Defamatory Statements:

    Keep a record of the defamatory statements, including screenshots, printouts, and any relevant context. If the defamation is online, make sure to save copies of the content before it’s removed or altered.

  2. Request a Retraction or Apology:

    Contact the individual or business responsible for the defamatory statement and ask for the content to be corrected or removed.

  3. Consider Legal Action:

    If a retraction or apology is not forthcoming, or if the defamation has caused significant harm to your business, you may need to pursue legal action. A lawyer specializing in defamation law can help you assess your case and take appropriate steps, which may include filing a defamation lawsuit.

  4. Injunctions or Court Orders:

    In some cases, an injunction may be sought to prevent further defamatory statements from being made or to have the defamatory content removed from the internet or other platforms.
