Employees in Ontario often wonder whether their employer must provide a written warning before terminating their employment. While many assume warnings are legally required, the reality is more nuanced. Ontario law does not mandate written warnings in all cases, but employers must follow strict procedural fairness rules when justifying termination for cause. This blog clarifies when warnings are necessary, the legal standards for performance management, and your rights if facing termination.

‍

1. Legal Framework: Termination With vs. Without Cause

In Ontario, employers can terminate employment in two ways:

‍

a) Termination Without Cause

• Employers may end employment without reason but must provide:
  
  • Notice or Pay in Lieu: Under the Employment Standards Act (ESA), minimum notice ranges from 1–8 weeks based on tenure.
  • Common Law Reasonable Notice: Courts often award significantly more (e.g., months or years) based on age, role, and job market.
• No Warning Required: Employers need not give warnings or justify the termination.

‍

b) Termination With Cause

• Employers can terminate immediately, without notice or severance, but only for serious misconduct or persistent poor performance.
• Burden of Proof: Employers must show they:
  
  • Provided clear expectations.
  • Warned the employee about deficiencies.
  • Offered a reasonable chance to improve.

‍

2. When Are Written Warnings Legally Required?

Written warnings are not automatically required by law but are critical to proving just cause:

‍

a) For Poor Performance

• Employers must demonstrate progressive discipline (e.g., verbal warning → written warning → termination).
• Example: An employee repeatedly missing deadlines may need documented warnings before termination for cause.

‍

b) For Misconduct

• Serious misconduct (e.g., theft, harassment) may justify immediate termination without warnings.
• Less severe issues (e.g., tardiness) typically require warnings.

‍

c) Unionized Workplaces

• Collective agreements often mandate progressive discipline, making warnings a contractual right.

‍

3. Employer Obligations for Performance Management

To avoid wrongful dismissal claims, employers should:

1. Set Clear Expectations: Provide job descriptions and performance metrics.
2. Document Issues: Track performance gaps or misconduct in writing.
3. Offer Support: Allow time for improvement (e.g., training, mentorship).
4. Follow a Fair Process: Ensure warnings are specific, timely, and non-discriminatory.

‍

4. Employee Rights and Recourse

If terminated without warnings or due process:

‍

a) Challenge “Just Cause” Claims

• Argue the employer lacked evidence of progressive discipline.
• Sue for wrongful dismissal to seek additional pay in lieu of notice.

‍

b) File an ESA Complaint

• If the employer withholds minimum notice/severance, contact the Ministry of Labour.

‍

c) Human Rights Claims

• If termination relates to a protected ground (e.g., disability, pregnancy), file with the Human Rights Tribunal of Ontario.

‍

5. Common Misconceptions

Myth 1: “Employers Must Give Three Warnings Before Firing You”

• Reality: No legal rule specifies the number of warnings. Courts assess whether the employer acted reasonably.

Myth 2: “A Written Warning Guarantees Job Security”

• Reality: A warning is a step in the process—not a shield. Employers can still terminate without cause by providing notice.

Myth 3: “Verbal Warnings Don’t Count”

• Reality: Verbal warnings can support a just cause defense, but written documentation is stronger.

‍

6. Key Takeaways

• Termination Without Cause: Legal without warnings, but notice/severance is required.
• Termination With Cause: Warnings are critical to proving the employee was unfit to continue employment.
• Procedural Fairness Matters: Employers must act in good faith; employees can challenge unfair processes.
• Unionized Employees: Often entitled to stricter progressive discipline under collective agreements.

Conclusion

While written warnings are not universally required in Ontario, they play a pivotal role in justifying terminations for cause. Employees should understand their rights to fair treatment, and employers must balance performance management with legal obligations. If you’ve been terminated without warnings or due process, consult an employment lawyer to assess your options.
