Workplace Misconduct in Ontario: How Employers Can Respond Without Triggering Legal Risk
Harinder2026-06-02T16:51:08-04:00When workplace misconduct arises, the instinct is to act decisively and quickly. That instinct is understandable but in Ontario employment law, how an employer responds to misconduct can create as much legal risk as the misconduct itself. A rushed investigation, an unsupported just cause termination, or an improper suspension can transform a manageable disciplinary situation into a wrongful dismissal claim, a human rights complaint, or a constructive dismissal dispute. Getting the process right from the first step is what separates a defensible outcome from an expensive one.
This means that an employer who correctly identifies genuine misconduct but handles the investigation, suspension, or termination incorrectly can still face significant legal liability. The quality of your process documentation, procedural fairness, proportionality of the response is assessed independently of whether the underlying conduct warranted a response at all.
Are you dealing with a workplace misconduct allegation in Ontario and considering discipline, suspension, or termination?
Missteps in the process create liability even where the misconduct itself was real. Get legal advice before taking any action particularly before suspending, alleging just cause, or terminating.

Conduct a proper investigation before drawing conclusions
The investigation must be thorough, neutral, and procedurally fair not a process designed to reach a predetermined outcome. Clearly define the allegations, give the employee a genuine opportunity to respond, use a neutral decision-maker without a stake in the outcome, and document every step including interviews, evidence reviewed, and findings. Where the allegation involves harassment, discrimination, or a significant credibility dispute between parties, consider using an external investigator.
A flawed investigation is one of the most common reasons Ontario employers lose misconduct disputes even where the underlying conduct was real. Courts assess whether the employee received procedural fairness, and where the process was rushed, biased, or under-documented, liability frequently follows regardless of the substantive outcome.
Manage the interim period carefully
During the investigation, you may need to separate the employee from the workplace or from the subject of the complaint. Options include temporary reassignment, changes to reporting structure, remote work arrangements, or paid or unpaid suspension. Each carries specific legal risk.
An unpaid suspension without pay must be clearly justified as a disciplinary measure using it simply as a holding pattern during an investigation can constitute constructive dismissal. An indefinite suspension, whether paid or unpaid, creates compounding risk the longer it continues. Get legal advice on the appropriate interim step before implementing it, as the wrong choice here can create liability before the investigation even concludes.
Apply a proportionate and consistent disciplinary response
Where misconduct is confirmed, the disciplinary response must be proportionate to the severity of the conduct and consistent with how similar situations have been handled in the past. Progressive discipline working through verbal warnings, written warnings, performance improvement plans, and suspension before termination remains the standard approach for ongoing or escalating conduct issues. Jumping to termination for a first or minor offence without documented warnings is one of the most common sources of wrongful dismissal exposure for Ontario employers.
Document every step of the disciplinary process, including what was communicated, when, and how the employee responded. This documentation is your evidence if the matter is later disputed.
Assess just cause rigorously before alleging it
Just cause termination means dismissing the employee without notice or severance. The threshold is extremely high in Ontario conduct must be serious enough to have irreparably destroyed the employment relationship to the point where continued employment is genuinely impossible. The employer bears the burden of proving just cause to that standard. Poor performance, isolated incidents, attitude concerns, or ordinary workplace friction almost never meet it.
An employer who alleges just cause and fails to prove it does not simply revert to owing notice the allegation itself, where made without a genuine basis, can attract additional bad faith damages. Get legal advice on whether the specific conduct actually meets the just cause threshold before the word "cause" appears in any communication to the employee or their counsel.
The disciplinary responses available to Ontario employers
Where Ontario employers create liability in misconduct situations
Acting before investigating
Terminating or suspending without a proper investigation particularly for harassment or fraud allegations is the most common source of procedural unfairness findings. Courts expect employers to know the facts before acting on them.
Poor or missing documentation
A disciplinary process without contemporaneous written records of what was alleged, what the employee said, what evidence was reviewed, and what decision was made cannot be defended effectively in litigation regardless of what actually happened.
Disproportionate responses
Terminating for a first offence, or for conduct that was minor or that the employer had previously tolerated without discipline, exposes the organization to wrongful dismissal claims where the response cannot be shown to be proportionate to the conduct.
Misusing suspension
An indefinite or unexplained suspension whether paid or unpaid can constitute constructive dismissal in Ontario. Suspensions must be time-limited, purposeful, and legally assessed before they are implemented.
Alleging just cause without evidence
Asserting just cause in a termination letter or severance offer without being able to prove it to the legal standard is one of the most expensive misconduct decisions an employer can make. A failed just cause allegation increases the employee's damages and can attract bad faith penalties.
Inconsistent application
Applying different disciplinary standards to different employees for similar conduct particularly where the inconsistency tracks along lines of protected characteristics supports both wrongful dismissal and human rights claims simultaneously.
Dealing with a misconduct situation in Ontario and unsure how to proceed?
The process matters as much as the conduct. Get legal advice before investigating, suspending, or terminating the earlier the better, and always before any just cause allegation is made.

Does workplace misconduct in Ontario automatically justify termination?
No. Misconduct exists on a spectrum, and the appropriate response depends on the severity and nature of the conduct, the employee's disciplinary history, and whether warnings or progressive discipline were applied. Only conduct that is serious enough to have irreparably destroyed the employment relationship meeting the high legal threshold for just cause justifies termination without notice or severance. Minor misconduct, first offences, and conduct previously tolerated without discipline typically require a progressive disciplinary response before termination becomes defensible.
What must a workplace investigation include in Ontario to be legally defensible?
A defensible Ontario workplace investigation clearly defines the allegations in writing, gives the employee a genuine and meaningful opportunity to respond to those allegations, uses a neutral decision-maker without a stake in the outcome, gathers evidence from all relevant sources including witnesses, and documents every step contemporaneously. Where the allegation involves harassment, discrimination, or a significant credibility dispute, using an independent external investigator significantly reduces procedural unfairness risk. An investigation that was designed to confirm a predetermined outcome will not withstand scrutiny.
Can suspending an employee in Ontario create constructive dismissal liability?
Yes. An indefinite suspension, or a suspension without a legitimate and documented purpose, can be characterized as constructive dismissal in Ontario allowing the employee to treat it as a termination and claim severance. Paid suspension during an active investigation is generally the safest interim measure where separation is required before findings are made. Unpaid suspension as a disciplinary measure must be clearly justified, proportionate to the conduct, and time-limited. Get legal advice before suspending an employee in any situation where the legal basis is not clear.
What happens if an employer alleges just cause in Ontario and cannot prove it?
Where an employer alleges just cause and fails to establish it at the legal standard conduct so serious that it irreparably destroyed the employment relationship the employer is liable for the full wrongful dismissal damages that would have been owed had the termination been handled without cause from the start. Where the just cause allegation was made without a genuine basis or was used opportunistically, courts may additionally award bad faith or aggravated damages. Alleging just cause without being able to prove it consistently makes a dispute more expensive than it would have been without the allegation.
When should an Ontario employer involve a lawyer in a misconduct situation?
Before taking any significant action ideally at the point where misconduct is first identified and a response is being contemplated. Legal advice is particularly important before any suspension, before the investigation begins where the allegations are serious, before any termination for cause is communicated, and before any settlement offer is made where a claim has been threatened. Early legal guidance prevents the most common and costly procedural errors. Involving a lawyer after a flawed investigation or premature termination limits what can be corrected.
