If you have been terminated, one of the first things you will want to understand is whether your employer is claiming just cause. The difference matters enormously — both for your immediate entitlements and for your ability to pursue a claim.

What wrongful dismissal means

In Ontario, every employee has the right to either reasonable notice before termination, or pay in lieu of notice. "Wrongful dismissal" does not mean your employer acted immorally or broke a contract in a traditional sense. It means the employer ended your employment without providing the notice — or equivalent pay — that the law requires.

This is the default outcome for most terminations. Even if your employer says the decision was for economic reasons, performance, or restructuring — if they failed to give proper notice, that is a wrongful dismissal.

What is just cause — and why the bar is so high

Just cause is the legal justification for terminating an employee with no notice and no severance. For an employer to successfully establish just cause, the misconduct must be serious enough to fundamentally rupture the employment relationship.

The Supreme Court of Canada in McKinley v BC Tel established that just cause is assessed contextually: the question is whether, in all the circumstances, the employee's conduct was incompatible with the continuation of the employment relationship. Ontario courts have consistently held that this is a demanding standard.

Employers frequently allege just cause when they should not. Common examples that rarely rise to the level of just cause include:

• Performance issues addressed without any progressive discipline

• A single incident of poor judgment

• Personality conflicts or management disagreements

• Policy violations where the rule was inconsistently enforced

Progressive discipline and condonation

Ontario courts expect employers to give employees a meaningful chance to improve before terminating for cause. An employer who overlooks misconduct — or who continues to accept satisfactory performance after a single incident — is generally held to have condoned that behaviour. Condonation can strip an employer of the right to rely on earlier conduct when they eventually terminate.

What happens when cause is alleged but not proven

When an employer alleges just cause and fails to prove it at trial, the consequences extend beyond simply owing notice pay. Courts may also award aggravated damages for the manner of dismissal, particularly where the cause allegation was made without a genuine factual basis or was used to pressure a settlement.

If your employer has alleged cause, do not make statements or sign anything without first obtaining legal advice.
