One of the most common mistakes Ontario employers make when terminating an employee is assuming that verbal warnings and a general sense of poor performance will be enough to justify dismissal for cause. They are not. Ontario courts have consistently held that employers bear the burden of proving just cause, and without documented evidence of progressive discipline, that burden is nearly impossible to meet. Good intentions and memories do not hold up under cross-examination.
Progressive discipline is a structured, step-by-step approach to managing employee misconduct or performance issues. It is designed to give employees a fair opportunity to correct their behaviour before more serious consequences follow. When done properly, it also creates a defensible record that demonstrates the employer acted reasonably, consistently, and in good faith. That record can mean the difference between a successful just cause termination and a costly wrongful dismissal judgment.
The Four-Step Framework (And What Courts Look For)
Progressive discipline typically follows a four-stage structure: verbal warning, written warning, final written warning, and termination. While there is no single formula required by Ontario law, courts and arbitrators expect to see a logical escalation that gives the employee reasonable notice that their job is at risk. Skipping steps without justification or applying discipline inconsistently across your workforce can quickly undermine your position.
At each stage, the documentation must answer four key questions: What specific conduct or performance issue occurred? When and where did it happen? What was communicated to the employee, and who was present? What improvement was expected, and by when? If your records cannot answer these questions clearly, they will not carry much weight when it matters most.
Courts also look for evidence that the employer genuinely intended to give the employee a chance to improve, not simply build a file to justify a predetermined outcome. That distinction is critical. Discipline that appears manufactured or retaliatory can expose an employer to aggravated or punitive damages in addition to a wrongful dismissal award.
Writing a Warning That Actually Holds Up
A written warning should read less like a vague reprimand and more like a professional record of fact. Start with the specific incident: include the date, the nature of the conduct, and any relevant prior discussions. Reference your workplace policies where applicable. Be direct about the impact the behaviour has had on the team, the client, or the business.
The warning must also outline clear expectations going forward and define what “improvement” looks like in concrete, measurable terms. Vague language like “we expect better performance” creates ambiguity that employees and their lawyers will exploit. Instead, use specific targets: “You are expected to meet your weekly sales quota of 15 units for the next 90 days” is far more defensible than “your performance must improve.”
Finally, include a consequence statement that explicitly tells the employee what will happen if the behaviour continues or the targets are not met. This is non-negotiable. If an employee cannot point to a document that told them their job was in jeopardy, courts are unlikely to find that termination was justified. Have the employee sign acknowledging receipt, and note in the document if they refuse to sign.
The Paper Trail: What to Keep and How to Keep It
Documentation is only as useful as it is accessible, organized, and complete. Every step in your progressive discipline process should be recorded in writing and stored in the employee’s personnel file. This includes meeting notes, performance reviews, email exchanges where conduct was discussed, attendance records, and any responses or rebuttals the employee provided. Do not discard or overlook records that are unfavourable to the employer’s position. Courts expect complete files, not curated ones.
Timing matters as well. Document incidents promptly, ideally the same day or within 24 to 48 hours. Reconstructed records written weeks or months after the fact are easy to challenge. If a conversation took place, follow it up with a brief written summary sent to the employee by email: “As discussed today, this letter confirms the verbal warning issued regarding your attendance on [date].” That one step transforms a forgettable conversation into a timestamped, corroborated record.
Be consistent across your workforce. If you disciplined one employee for a particular infraction, you must apply the same standard to others in similar situations. Courts and arbitrators are alert to selective enforcement, and if an employee can show that others were treated more leniently for the same conduct, it can raise a human rights concern or simply undermine your credibility as an employer acting in good faith.
When Progressive Discipline Can Be Bypassed
Not every situation calls for a gradual escalation. Ontario law recognizes that some forms of misconduct are so serious that they justify immediate termination for cause without prior warnings. These typically include theft, fraud, workplace violence, serious breaches of confidentiality, or conduct that fundamentally destroys the employment relationship. That said, courts apply a high standard to just cause dismissals even in serious cases. The conduct must be proportionate to the consequence, and context still matters.
If you are considering bypassing progressive discipline based on the severity of a single incident, document the incident thoroughly and be prepared to demonstrate why a lesser consequence was not appropriate. Employers who skip steps without a clear rationale often find themselves defending not just the termination, but the entire disciplinary process.
