Can You Be Fired for Social Media Posts in Ontario?

In September 2025, Washington Post columnist Karen Attiah was terminated after making social media posts about the assassination of conservative activist Charlie Kirk. Closer to home, just months earlier, York Region paramedic Katherine Grzejszczak was fired after posting a Facebook comment criticizing Israel’s military operations in the Middle East.

Both cases highlight the same question: Can you be fired for what you post on social media outside of work hours? The answer in Ontario is yes—but the circumstances matter. This Q&A guide addresses the some of the key questions about employment law in Ontario evolving around social media posts, helping you understand when your off-duty posts can cost you your job.

1. Can my employer legally fire me for something I post on social media in Ontario?

Yes, your employer can potentially terminate your employment based on social media posts, but the circumstances matter significantly. Under Ontario’s Employment Standards Act, employers can terminate employees for any reason, provided they follow proper procedures. However, there are two types of termination to understand:

• Termination without cause: Your employer can let you go without providing a reason, but they must give you proper notice or pay in lieu of notice (severance).
• Termination for cause: Your employer can fire you for cause if the social media conduct negatively affects the employer’s legitimate interests, but they must meet a high legal threshold to justify immediate dismissal without any compensation.

The key question is whether your social media activity has created a real and material connection to your workplace that justifies the termination.

2. What types of social media posts can lead to termination for cause?

Courts and arbitrators have upheld dismissals in cases involving:

• Discriminatory or hateful content: Posts containing racist, sexist, or otherwise discriminatory remarks
• Harassment of co-workers: Online comments that target coworkers, even without naming them directly
• Confidential information breaches: Sharing proprietary business information or trade secrets 
• Severe damage to employer reputation: Posts that discourage customers from using the employer’s products or services
• Threats or violence: Content suggesting violent acts, even if made in jest

3. Does my right to free speech protect me from being fired for my posts?

No. Many people misunderstand how freedom of expression works in employment contexts. Canada’s Charter of Rights and Freedoms guarantees freedom of expression, but it applies to government actions, not private employment relationships. This means:

• Private employers can discipline or terminate you for posts that harm their organization
• You can express political opinions, but your employer can act if those posts damage the company

That said, your employer cannot terminate you for discriminatory reasons prohibited under the Ontario Human Rights Code, such as firing you based on your religion, race, gender, or other protected grounds. 

4. Can I be fired for “whistleblowing” or raising workplace concerns on social media?

This is a complex area. Ontario employees are protected against reprisal for attempting to exercise their rights under the Occupational Health and Safety Act or the Employment Standards Act.

However, the manner and forum matter. Posting about workplace safety concerns publicly on social media is very different from following proper internal reporting procedures. You may have protection if you’re exercising rights under employment or safety legislation, reporting illegal activity, or raising genuine health and safety concerns.

But even legitimate concerns should generally be raised through proper channels first. Public social media posts can still damage your employment relationship.

5. What if I don’t mention my employer in my posts?

Even if you don’t explicitly identify your employer in a post, you may still be linked to your workplace if your account or social media presence can be easily connected to your job.

Consider these factors:

• Your profile lists your employer
• You’ve posted workplace photos or discussed your job previously
• Colleagues or customers follow you
• Your posts reference workplace incidents or people who can be identified
• You have a public-facing role in the company

5. Does having a social media policy at work change anything?

Yes, significantly. If an employee violates workplace social media policies—particularly if they have signed an agreement acknowledging them—disciplinary action may be justified.

Employers with clear, well-communicated social media policies are often in a stronger position to discipline employees who violate those policies. However, even with a policy:

• The employer must enforce it consistently
• The discipline must be proportionate to the violation
• The policy must be reasonable and lawful

If you’ve never been provided with a social media policy or it hasn’t been enforced consistently, this could work in your favour if you challenge a termination.

6. What should I do if I’m disciplined or fired over a social media post?

If you face termination or discipline over social media activities, take these steps:

• Do not sign anything immediately: Severance packages and releases should be reviewed by an employment lawyer before you accept them.
• Document everything: Keep copies of the posts in question, any communications with your employer, and your termination letter.
• Avoid discussing it on social media: Don’t compound the problem by posting about your termination or employer on the very platform that costs you your job. 
• Seek legal advice promptly: An employment lawyer can assess whether:
  • The termination was lawful
  • You were provided adequate notice or severance
  • You have grounds for a wrongful dismissal claim
  • The employer had legitimate cause

While you have freedom of expression as a Canadian, that freedom doesn’t shield you from employment consequences in the private sphere. The safest approach is to maintain professional boundaries online and remember that in today’s interconnected world, there’s no true separation between your digital presence and your professional reputation.
