How to Respond to an HRTO Application: A Guide for Ontario Employers

An HRTO application response for Ontario employers is not optional, and the margin for error is thin. When your organization receives a Human Rights Tribunal of Ontario application, the clock starts immediately. You have 35 days to file a complete, substantive response or you risk losing your right to participate in the proceeding entirely. The HRTO will not wait for you to get organized, retain counsel, or locate documents. If you miss the deadline or file something incomplete, the Tribunal can proceed without your input and a decision can be made against you without hearing your side.

This guide covers what Ontario law actually requires, the procedural steps you need to follow, the mistakes that trip up employers, and what happens when things go wrong. If you are holding a notice with an HRTO file number on it, read this carefully and act quickly.

The Human Rights Code, R.S.O. 1990, c. H.19, gives the HRTO authority to adjudicate complaints involving protected grounds in employment, including race, disability, sex, age, family status, and a dozen others under section 5. When an applicant files a Form 1 Application and the HRTO accepts it as complete, the Tribunal delivers a copy to you as the respondent. That delivery notice triggers your 35-day deadline to file Form 2, the Response.

HRTO Rule 15.1 sets this deadline. It is not a suggestion. The Form 2 must be filed with the HRTO Registrar at HRTO.Registrar@ontario.ca with your file number in the subject line. You also must deliver a copy to the applicant and file Form 23, the Statement of Delivery, confirming you have done so. Skipping Form 23 is treated as improper service and can result in your Response being rejected.

One change employers need to know about for 2025 and forward: all applications filed on or after June 1, 2025 are subject to mandatory mediation. The HRTO schedules it automatically. You do not opt in. If you fail to attend mandatory mediation, the application proceeds without further notice to you. You also lose the right to participate in or defend the hearing. There is no grace period for being surprised by the scheduling. Use the updated Form 2 effective June 15, 2025. The old version is rejected.

A generic denial will not protect you. The HRTO expects a Response that directly addresses every allegation in the application. That means going through the Form 1 line by line, admitting or denying each factual claim, and providing your version of events with dates, context, and specifics. If you simply write “the employer denies all allegations,” you have filed a document that the HRTO will treat as non-responsive.

Your Response should identify any witnesses who can support your position and attach all relevant documentation: performance reviews, email correspondence, disciplinary records, attendance logs, applicable workplace policies, and any communications related to the incidents alleged. If you are referencing a document in your Response, attach it. If you cannot attach everything by the filing date, you have five business days to follow up with supporting documents, but get your Form 2 in on time.

If you are seeking early dismissal or deferral of the application, that argument must be included in your Form 2, not filed later as a separate motion. HRTO Rule 8.2 permits early dismissal on specific grounds: lack of jurisdiction, the matter has already been decided between the same parties on the same issues, the proceeding is duplicative or more appropriately dealt with elsewhere (such as a labour arbitration or Ministry of Labour claim), or the applicant lacks standing. Your argument must be complete. The applicant will then have the opportunity to file Form 3, a Reply, responding to your dismissal request.

Missing the 35-day deadline is the most serious error, but it is far from the only one. Here are the mistakes that come up regularly in HRTO proceedings.

Filing an incomplete Response. The HRTO will not consider motions, preliminary objections, or dismissal requests until a complete Form 2 is on file. Employers sometimes file a partial response with the intention of supplementing it later. That approach backfires. File everything together.

Failing to disclose related legal proceedings. Under section 34(11) of the Human Rights Code, if the same underlying facts are being litigated elsewhere, such as in civil court or through a labour arbitration, you must disclose that in your Response. Failing to do so can result in the application being deferred or dismissed, and it damages your credibility with the Tribunal.

Not filing Form 23. Filing your Response without confirming delivery to the applicant through Form 23 is treated as improper service. The Response may not be accepted. This is a procedural step that is easy to overlook and costly to miss.

Raising objections without a full Response. If you believe the application should be dismissed because the limitation period has expired under section 34(1) of the Code, you still need to file a complete Form 2 along with your argument. You do not get to skip the substantive response and argue process only.

Using the old Form 2. Any Response filed after June 15, 2025 using a pre-June version of Form 2 will be rejected. Confirm you are using the current version from tribunalsontario.ca/hrto/forms before you file.

The moment the HRTO delivery notice arrives, start a file and mark your 35-day deadline. Do not wait to see how serious the situation is. Do not assume the application is baseless and therefore easy to handle. Every application that clears the HRTO’s completeness review is a live proceeding.

Gather documents immediately. Preserve all email and electronic communications, HR files, disciplinary records, and anything related to the employee, the incidents alleged, or the decision-making described in the Form 1. If litigation holds are not already standard practice at your organization, implement one now.

Identify the people involved on your side: the manager or supervisor named, HR personnel who handled the matter, and anyone else with first-hand knowledge. Get their accounts in writing while the events are fresh. Their recollections will matter significantly if the case proceeds to a hearing.

Review the application against the protected grounds under the Ontario Human Rights Code. Understand what ground the applicant is claiming and what section of the Code applies. A disability discrimination claim under section 5 with a failure-to-accommodate angle requires a different substantive response than a racial harassment claim under section 5(2). Know what you are defending before you draft a single sentence of your Response.

For applications subject to mandatory mediation (filed June 1, 2025 or later), prepare for that process from the beginning. Mediation is not a formality. A significant proportion of HRTO applications settle at or before mediation. Come with authority to negotiate, a clear understanding of your exposure, and an honest assessment of the facts.

The consequences of a botched HRTO response range from procedural penalties to an outright loss on the merits. If you miss the deadline, the HRTO may send a “No Response to Notice of Application” letter requiring explanation. That is the optimistic scenario. The Tribunal can also simply proceed without you, which means a finding on the application is possible without your evidence, your witnesses, or your arguments on record.

If the application proceeds to a hearing and you lose, HRTO remedies under the Human Rights Code are significant. The Tribunal can award monetary compensation for lost income, damages for injury to dignity, feelings, and self-respect (which have reached $50,000 and higher in serious cases), and public interest remedies including mandatory training, policy changes, and compliance monitoring. There is no cap on damages under the Code.

A weak Response also damages your credibility throughout the proceeding. The HRTO adjudicator sees your Form 2. If it reads as evasive, incomplete, or inconsistent with the documents you later produce, that affects how your evidence is weighed. The Response is your first impression in a process where credibility matters enormously.

Ontario employers often face situations where the same facts give rise to multiple proceedings simultaneously: an HRTO application, an ESA complaint to the Ministry of Labour, a grievance under a collective agreement, or civil litigation. The HRTO has authority to defer an application pending the outcome of another proceeding if that other process could appropriately deal with the substance of the human rights claim.

If you intend to seek deferral, that argument belongs in your Form 2. You need to explain which other proceeding is underway, how it overlaps with the HRTO application, and why deferral is appropriate. This is a legal argument, not a paperwork request. The applicant will respond and the HRTO will decide. Deferral is not guaranteed and the Tribunal will not defer a matter simply because another process exists. The overlap must be substantive.

If you are a federally regulated employer, the applicable legislation is the Canadian Human Rights Act and the Canadian Human Rights Commission process, not the HRTO. The procedural steps differ. Know which jurisdiction governs your workforce before you file anything.

If the application involves serious allegations, multiple incidents, a named individual who is still employed, or a claim with significant damages exposure, you need experienced help before you file. A poorly drafted Form 2 is difficult to walk back. The positions you take in your Response follow you to mediation and hearing.

Smaller employers without in-house HR or legal counsel are particularly at risk. The HRTO process is designed to be accessible to self-represented applicants, which means the Tribunal assumes parties understand the rules. That assumption applies to respondents too. “I didn’t know I had to file a complete response” is not a defence the Tribunal accepts, and it will not restore your right to participate once the deadline has passed.

The cost of getting proper advice before you file a Form 2 is a fraction of the cost of losing your ability to defend an application on the merits. If you are uncertain about the process, the strength of your position, or how to structure your response, get experienced help before the 35-day clock runs out.
