Frustration of contract in Canada happens when an unexpected event, through no fault of the employer or employee, makes it impossible for the employment relationship to continue.

In employment law, frustration most often comes up when a serious illness or disability leaves an employee unable to return to work for the foreseeable future. But being away from work for a long time does not automatically mean your contract is frustrated.

If you could return with reasonable accommodation, modified duties or a gradual return-to-work plan, your employer can’t simply use the word “frustration” to avoid its legal obligations.

⚠️ Don’t resign or sign a release because your employer says your employment contract has been frustrated. Your medical prognosis, accommodation options and termination compensation should be reviewed first.

What Does Frustration of Contract Mean?

Frustration means something outside both parties’ control has made the employment contract impossible to carry out as originally intended.

It is different from an ordinary firing. An employer can’t create frustration simply because continuing the employment relationship has become inconvenient or expensive.

Situations that can raise frustration issues include:

  • a serious long-term illness or disability;
  • an unforeseen event that permanently makes the work impossible; or
  • a legal change that makes the employee unable to perform an essential part of the job.

The most common situation is prolonged medical absence.

💡 Frustration happens because of the actual circumstances—not because an employer writes “frustration of contract” in a termination letter.

Can Illness or Disability Frustrate an Employment Contract?

Yes, but only when there is no reasonable prospect that the employee will be able to return to work within a reasonable period of time.

There is no automatic rule that says a contract is frustrated after six months, one year, two years or any other fixed period away from work.

The important questions include:

  • How long have you been unable to work?
  • What does your current medical prognosis say?
  • Is improvement expected?
  • Is there a realistic return-to-work date?
  • Could you return with modified duties, hours or another accommodation?

Does being on long-term disability mean your contract is frustrated?

No. Receiving long-term disability benefits does not automatically end your employment contract.

LTD benefits deal with income while you are disabled. Frustration deals with whether the employment relationship can realistically continue. Medical evidence about your ability to return to work is much more important than the simple fact that you receive LTD benefits.

Frustration of Contract and the Duty to Accommodate

An employer can’t use frustration of contract to avoid its duty to accommodate an employee with a disability.

Employers must consider reasonable ways to help an employee continue working or return to work, up to the point of undue hardship.

Depending on your medical restrictions, accommodation can include:

  • modified duties;
  • reduced or adjusted hours;
  • a gradual return to work;
  • changes to how duties are performed; or
  • other reasonable workplace changes.

If you can perform the essential parts of your job with reasonable accommodation, ending your employment because of your disability can create serious legal problems for the employer.

⚠️ Keep communicating with your employer during medical leave. Provide reasonable updated medical information about your restrictions, prognosis and ability to return when requested.

Do You Get Severance If Your Contract Is Frustrated?

You can still be owed money when an employment contract is frustrated, but the amount depends on the province and why the contract became frustrated.

If frustration is legally established, the employee normally loses the much larger common-law reasonable notice that can apply to an ordinary termination without cause.

However, employment standards rights are separate. Some provinces preserve minimum termination or severance payments in particular frustration situations.

Don’t assume frustration means you are owed nothing. The applicable provincial rules should be checked before you accept the employer’s calculation.

Frustration of Contract vs. Wrongful Dismissal

If the facts do not actually support frustration, ending your employment can instead amount to a wrongful dismissal.

Warning signs include an employer that:

  • relies only on how long you have been off work;
  • ignores a realistic return-to-work date;
  • does not consider modified duties or accommodation;
  • relies on outdated medical information; or
  • treats LTD benefits as proof that you will never return.

If frustration can’t be established, you can have the same termination and severance pay rights that apply to an ordinary dismissal—including up to 24 months’ pay.

What Should You Do If Your Employer Claims Frustration?

Do not accept the employer’s conclusion until the medical evidence, accommodation history and compensation have been reviewed.

  1. Get the employer’s position in writing. Keep the frustration or termination letter.
  2. Review your medical evidence. Your prognosis and ability to return are central to the issue.
  3. Save accommodation records. Keep emails about modified work, restrictions and return-to-work plans.
  4. Check what you are being paid. Frustration does not automatically mean zero compensation.
  5. Don’t resign. There is normally no reason to provide your employer with a resignation letter.
  6. Don’t sign a release before review. Once signed, you usually can’t return for additional compensation.
⚠️ Unionized? A frustration-of-contract termination or disability accommodation dispute must go through your union and the grievance process. Samfiru Tumarkin LLP’s employment law team can’t assist with unionized workplace disputes.

Frustration of Contract FAQs

How long do you have to be off work before your contract is frustrated?

There is no fixed deadline. The key question is whether you have a reasonable prospect of returning to work within a reasonable period.

Can my employer terminate me while I am on LTD?

Possibly, but LTD does not automatically justify termination. Your medical prognosis and the employer’s accommodation obligations still matter.

Can I claim that my own contract is frustrated?

Yes, in an appropriate case. Get legal advice first because frustration permanently ends the employment relationship.

Does frustration mean no severance?

Not always. Common-law notice normally ends with true frustration, but statutory termination and severance rights vary by province and circumstances.

Frustration of contract is a high-stakes issue because a valid frustration can significantly reduce an employee’s termination compensation. But an employer can’t establish frustration simply because you have been away from work for a long time.

If your employer says your contract has been frustrated because of illness, disability or medical leave, the employment lawyers at Samfiru Tumarkin LLP can review your medical evidence, accommodation history and termination rights before you sign anything.

Has Your Employer Said Your Contract Is “Frustrated”?

Don’t assume a long medical leave means your employment or severance rights have disappeared.
