Can I get extra damages if my employer fired me in a humiliating or bad-faith way in Ontario?

Yes. Ontario courts can award additional moral damages on top of ordinary notice-based damages where the manner of your dismissal itself was unfair, untruthful, or unnecessarily harsh - for example, being misleadingly told the termination was for one reason when it was not, or being dismissed in a deliberately humiliating way in front of colleagues. These damages compensate for the mental distress caused specifically by how the dismissal was carried out, which is a distinct legal question from whether adequate notice was given for the job loss itself.

To succeed, you generally need to show the employer's conduct during the dismissal process was genuinely unfair or in bad faith, not just that being fired was upsetting, since losing a job is inherently difficult regardless of how considerately it is handled. These claims require specific evidence about how the termination was actually conducted - what was said, by whom, and in what setting - which is why documenting exactly what happened during and immediately after the termination meeting matters considerably to a claim like this.
