About Mitigation

After being terminated from your job in Ontario, you might feel lost and overwhelmed. While you may be entitled to damages for wrongful dismissal, it's crucial to understand a legal concept known as the 'duty to mitigate'. In simple terms, mitigation means you are legally required to take reasonable steps to reduce your financial losses by trying to find a new, comparable job. You cannot simply sit back and wait for a settlement from your former employer; the law expects you to be proactive.

This duty is a central element in wrongful dismissal cases. Your former employer will almost certainly raise the issue, and the burden will be on them to prove that you failed to make reasonable efforts to find work. If they succeed, a court can reduce the amount of damages you receive. What constitutes a 'reasonable effort' is highly specific to your situation. It depends on factors like your age, the type of work you did, your salary, and the job market conditions for your field. For example, a senior executive is not expected to apply for entry-level positions, but they are expected to actively seek out comparable senior roles.

It is essential to distinguish this common law duty from your statutory entitlements. Your minimum entitlements to termination pay and severance pay under Ontario's Employment Standards Act, 2000 (ESA) are not subject to mitigation. You receive this money regardless of whether you find a new job the next day. The duty to mitigate only applies to the additional 'reasonable notice' damages you might be awarded by a court in a wrongful dismissal claim.

Because the success of your mitigation efforts can significantly impact the outcome of a legal claim, documenting your job search is critical. Keeping detailed records can be your best defence against an employer's claim that you didn't try hard enough. Every employment situation is unique, and assessing whether your job search efforts meet the legal standard requires a careful look at the facts, making professional guidance invaluable in these circumstances.

Frequently Asked Questions

What does the 'duty to mitigate' actually mean after I've been fired?

It means you have a legal responsibility to actively look for a new job that is comparable to the one you lost. This is to minimize the financial damages resulting from your termination. Your efforts directly impact how much wrongful dismissal pay (beyond ESA minimums) you may be entitled to.

Do I have to accept any job offer to show I'm mitigating?

No. You are only expected to seek and accept 'comparable employment,' which means a job with similar pay, status, responsibilities, and location. You are not required to take a significant pay cut or a job in a completely different field, especially in the early stages of your search.

How can I prove that I tried to mitigate my damages?

Documentation is key. Keep a detailed log of your job search, including websites you've used, positions you've applied for, networking contacts you've made, interviews you've attended, and any job offers you've received. Save all related emails and application confirmations.

Does mitigation affect the termination pay and severance my employer paid under the ESA?

No, it does not. Your entitlements under the Employment Standards Act, 2000 are a minimum standard and are not reduced by mitigation. The duty to mitigate only applies to common law reasonable notice damages, which are awarded in a wrongful dismissal claim.

What happens if I find a new job that pays less?

If you take a lower-paying job as part of a reasonable mitigation effort, you may still be able to claim the difference in salary from your former employer for the remainder of your notice period. This is a common part of damage calculations in wrongful dismissal cases.

My former employer is accusing me of not looking for work. When should I get a lawyer?

You should consult with an employment lawyer immediately if your former employer alleges you have failed to mitigate. A lawyer can help you assess the strength of your job search evidence and formulate a proper response to protect your claim for damages.

Common Scenarios

  • A software developer is terminated and keeps a detailed spreadsheet of the 50 jobs they applied for over three months, including dates, links, and outcomes.
  • A senior manager is terminated and refuses to apply for any roles that aren't at the Vice-President level, potentially narrowing their job search too much and risking a failure to mitigate argument.
  • After being laid off, a construction worker is offered a much lower-paying job by a different company and turns it down, which is likely considered a reasonable refusal in the context of mitigation.
  • An administrative assistant receives a job offer from their former employer to return to a similar role but refuses it without a good reason, which a court could see as a failure to mitigate damages.
  • A marketing professional decides to start their own consulting business after being terminated, which can count as mitigation if it's a genuine and reasonable attempt to earn income.

What You Should Know

  • Start your job search immediately after termination and keep meticulous records of every application, interview, and networking conversation.
  • Focus your search on roles comparable to your previous one in terms of salary, seniority, and duties. You can broaden your search as more time passes.
  • Do not automatically ignore or reject a recall or re-employment offer from your former employer; refusing a reasonable offer can be viewed as a failure to mitigate.
  • Remember that your statutory pay under the Employment Standards Act, 2000 is safe; mitigation only impacts your potential common law wrongful dismissal damages.
  • If you are unsure whether a job offer is 'comparable' or how to respond to an allegation of failure to mitigate, seek advice from an Ontario employment lawyer to protect your rights.
