Progressive Discipline in Ontario: What Employers Must Do Before Terminating

Progressive discipline in Ontario is not spelled out in the Employment Standards Act, 2000, and that trips up a lot of employers. They assume that because the law doesn’t mandate a specific process, they can skip straight to termination when an employee is underperforming or causing problems. That assumption gets expensive. Ontario courts expect a graduated, documented approach before an employer can defend termination for cause. Without it, you are paying out notice, sometimes a lot of it, for a dismissal you thought was justified.

This post lays out exactly what Ontario employers need to do before pulling the trigger on a termination, what mistakes to avoid, and when you can legitimately skip the process entirely.

No Ontario statute requires you to follow a specific discipline ladder. The ESA doesn’t mention progressive discipline. The Occupational Health and Safety Act (OHSA) requires written policies on workplace violence and harassment, but says nothing about how you escalate consequences for violations. The Ontario Human Rights Code (OHRC) requires that you not discriminate, not that you discipline in a particular sequence.

Where progressive discipline becomes legally critical is in common law. When a dismissed employee sues for wrongful dismissal, an Ontario court asks one central question: did the employer have just cause? Just cause is a high bar. It means the misconduct or performance failure was serious enough, and the employer’s response proportionate enough, to warrant dismissal without notice or severance. Courts consistently look at whether the employer warned the employee, gave a real opportunity to improve, and documented what happened. Without that evidence, the just cause argument collapses.

For unionized workplaces under the Ontario Labour Relations Act, 1995, the bar is even more explicit. Arbitrators apply progressive discipline principles as a default. Skipping steps without clear justification usually means the discipline gets overturned or reduced.

The ESA does require that employees with three or more months of service receive notice or pay in lieu when terminated without cause. That ranges from one to eight weeks depending on tenure. Severance pay kicks in at five years if the employer’s payroll exceeds $2.5 million. Termination for cause, if you can prove it, eliminates those obligations, but proving it without a documented progressive discipline process is extremely difficult.

There is no single mandatory sequence, but courts and arbitrators expect something that looks roughly like this: a private conversation, a written warning, a performance improvement plan or suspension, and then termination as a last resort. The exact steps depend on the severity of the issue, how long the employee has been with you, and whether the problem is performance-based or conduct-based.

Verbal warning or informal discussion. Address the problem promptly and privately. Be specific about what the employee did or failed to do, what the expectation is, and what needs to change. Ask the employee for their side. If training or support is needed, say so. Even this conversation should be noted in writing internally, even if the employee never signs anything at this stage.

Written warning. If the issue continues or is serious enough to warrant documentation from the start, put it in writing. Describe the specific incidents with dates, state the standard that was not met, explain the consequence of continued failure, and give the employee an opportunity to respond. Have them sign an acknowledgment that they received it, not that they agree with it.

Performance Improvement Plan.For performance issues, a PIP sets measurable goals, timelines, and the support the employer will provide. This is where employers often get lazy. A PIP that just says “improve attitude” is useless. Make the goals observable, put a date on each one, and schedule check-ins.

Final written warning or suspension. This signals that continued problems will result in termination. A suspension, paid or unpaid depending on the circumstances and your policy, can be an appropriate step for serious or repeated misconduct. It makes clear the relationship is at risk.

Termination. Only after the process above has run its course and the employee has failed to meet documented expectations. Your termination letter and supporting file should show the full history.

Before you discipline, you need to ask whether the conduct or performance issue has any connection to a protected ground under the OHRC. If an employee is chronically absent and that absence links to a disability, family status, or another Code-protected ground, discipline is not your first move. Accommodation is. You need to investigate what is driving the behaviour, offer appropriate support, and document that process before imposing any sanctions.

Failing to do this is one of the most common and costly mistakes Ontario employers make. A discipline record that looks clean on its face can be undone entirely if the Human Rights Tribunal finds the underlying issue was disability-related and the employer never explored accommodation. Remedies under the OHRC can include compensation for lost wages, general damages for injury to dignity, and reinstatement.

Under the OHSA, any discipline involving a workplace harassment or violence allegation must follow a proper investigation before any sanction is imposed. The employer has statutory obligations under sections 32.0.1 to 32.0.7 of the OHSA to investigate complaints appropriately, and those obligations exist independently of whatever your progressive discipline policy says. Disciplining the wrong person, or disciplining too quickly without completing the investigation, creates liability on two fronts simultaneously.

There are situations where progressive discipline is not required before termination. If an employee commits a serious enough single act, theft, fraud, physical violence, a major safety violation, or serious sexual harassment, courts have consistently held that immediate termination for cause is defensible. The threshold is high and fact specific, but it exists.

The conditions are non-negotiable even in these cases. You must investigate before you terminate. You must be able to show the employee understood the rules and knew the conduct was prohibited. You must act without undue delay, because if you take weeks to respond after learning about the incident, you risk being seen as having condoned it. And you must document everything.

Do not assume that severity alone justifies skipping process. An employer who fires someone for alleged theft without conducting a fair investigation, giving the employee a chance to respond, and confirming the facts will often find themselves in worse legal position than an employer who completed that process and still terminated.

The errors that produce the most expensive outcomes in Ontario employment disputes are rarely dramatic. They are procedural, and they are almost always avoidable.

No documentation or weak documentation.Notes that say “spoke to employee about performance” with no dates, specifics, or outcomes are nearly useless. If the record does not show what was said, what the expectation was, and what the consequence of further failure would be, it does not help you in court. Document every disciplinary conversation the same day it happens.

Inconsistent application. If you applied progressive discipline rigorously to one employee and skipped steps for another in similar circumstances, you have handed the dismissed employee an OHRC argument. Courts look at how the employer treated comparators. If the pattern suggests certain employees were treated differently based on a protected ground, the just cause argument becomes a discrimination complaint.

No clear policy. Employees should know from day one what your discipline process looks like, what kinds of behaviour put their employment at risk, and what escalation looks like. A written policy, reviewed at least annually, communicated to all employees, and applied consistently is your first line of defense and your strongest evidence of good faith.

No genuine improvement opportunity. A PIP that is designed to fail, unrealistic timelines, moving targets, lack of support, does not demonstrate good faith. Courts have seen enough of them to recognize one. If you are running a process just to build a paper trail toward a dismissal you already decided on, that approach tends to backfire.

No investigation before discipline. Discipline without a fair investigation is a common procedural failure. This means collecting the facts, speaking to relevant witnesses, and giving the employee a genuine opportunity to provide their perspective before any decision is made. This is not optional when the matter involves harassment, safety, or serious misconduct.

Documentation is not optional and a single note is not enough. A defensible discipline file contains the specific incidents with dates and times, the exact standard or policy that was not met, the employee’s response when you raised the issue, what corrective action was agreed to and by when, and the consequence communicated if the problem continued. Each document should be signed by both the manager and the employee, with a note if the employee declined to sign.

Keep this file separate from the general HR file and maintain it consistently throughout the relationship. Courts and arbitrators look at the full history. If your earliest documentation is from two weeks before termination after three years of undocumented problems, the record reads as pretext, not a good-faith process. Discipline files should grow in real time, not be assembled after the decision to terminate has already been made.

If you are using performance improvement plans, every goal in the plan needs to be specific, observable, and time-bound. Document each check-in during the PIP period. Note what the employee did, what support was provided, and whether the goal was met. If the PIP ends without improvement, that documented trail is the foundation of your just cause argument. Without it, you are paying notice on a dismissal you thought was deserved.

Finally, review who has access to the discipline file and how long you keep it. Ontario employers have obligations under PHIPA, PIPEDA, and in some cases MFIPPA regarding employee personal information. Discipline records are personal information. Retain them for as long as they are relevant to a potential claim, typically six years after the employment relationship ends, and restrict access to those with a legitimate need.
