Federal unjust dismissal complaint in Canada: eligibility, 90-day deadline, reasons and evidence

Confirm that Part III of the Canada Labour Code applies

The federal unjust dismissal process is not the ordinary termination route for every Canadian employee. Begin by identifying the employer’s legal name, industry, workplace and the employee’s actual role. Many workplaces are regulated by provincial or territorial employment standards rather than Part III of the Canada Labour Code. Record why the employer is federally regulated and preserve the contract, employer information, workplace address and business description supporting that conclusion. Do not infer federal jurisdiction merely because an employer operates nationally or has customers in several provinces.

If jurisdiction is uncertain, resolve it before the 90-day complaint period expires. Prepare a short jurisdiction note stating the facts that connect the employment to federal labour standards. The note should be factual rather than conclusory. If a provincial route may instead apply, record that possibility and obtain current advice. A detailed complaint on the merits cannot cure filing in the wrong system, so jurisdiction belongs at the front of the working file rather than at the end.

Test all threshold eligibility conditions

Current Labour Program guidance states that an unjust dismissal complainant generally must have been dismissed, including a qualifying constructive dismissal, have at least 12 consecutive months of employment with the same employer, not be covered by a collective agreement and not be a manager. Record the start date, dismissal date, continuity of service, bargaining status and actual managerial responsibilities. Preserve payroll, contract and job-description records that support these threshold facts.

Do not rely only on job title when considering the manager exclusion. Record authority over staff, decision-making powers, reporting lines, responsibility for discipline or hiring and the actual day-to-day function. If a collective agreement may apply, obtain it and identify the grievance mechanism. If service was interrupted, list the dates and reason instead of assuming continuity. The eligibility analysis should be capable of being checked against documents because a strong dismissal dispute may still fall outside this particular statutory route.

Calculate the 90-day filing deadline immediately

The federal eligibility guidance states that an unjust dismissal complaint must be filed within 90 days from the date of dismissal. Put the dismissal date and calculated final filing date on a separate deadline sheet at the start of the file. Preserve the termination letter, dismissal email, meeting record or other evidence showing when employment ended. Where the claim is constructive dismissal, the relevant dismissal date may be disputed and should be analyzed carefully before the deadline is assumed.

Do not wait for severance negotiations, an internal appeal or a request for reasons to finish before protecting the statutory period. Settlement discussions can be useful but should not be assumed to suspend the 90-day deadline. If the ordinary period has already expired, check the current statutory extension provisions and official instructions immediately. State the true chronology rather than backdating a complaint. If different possible dismissal dates exist, record each position and calculate conservatively.

Preserve the employer’s reasons exactly

Keep the termination letter and a contemporaneous note of the dismissal meeting. Canada.ca explains that after an unjust dismissal complaint is received, the employee or the Head of Compliance and Enforcement may request a written statement of the reasons for dismissal and that the employer must provide that statement within 15 days after the request. If the employer’s explanation changes, build a table showing each stated reason, who gave it and when.

Do not paraphrase the employer’s reason into stronger or weaker language. If misconduct is alleged, identify the conduct, policy and evidence. If performance is relied on, preserve objectives, reviews, warnings, coaching records and improvement plans. If restructuring or lack of work is advanced, keep the communication describing that reason. Accurate recording of the employer’s case lets the complainant challenge what was actually asserted rather than a reconstructed explanation created after the dispute began.

Build a complete employment chronology

Create a dated chronology from hiring through dismissal. Include role changes, performance reviews, warnings, complaints, accommodation requests, leave, investigations, disciplinary meetings, policy changes and the termination. Give each material event an exhibit reference. Do not fill the chronology with routine emails that have no connection to the dismissal. The purpose is to allow a reviewer to see the sequence that led to the employer’s decision and whether the stated reason is consistent with the historical record.

Where facts are contested, identify both versions. If the employer says a warning was issued and the employee denies receiving it, record the document or witness relied on by each side. If the employee previously acknowledged a performance problem, include that fact and explain subsequent improvement or context. A credible chronology does not delete adverse material that the employer is likely to produce. It marks the disagreement and preserves the evidence needed to resolve it.

Separate unjust dismissal from monetary labour standards complaints

The federal labour standards system contains several complaint categories. An unjust dismissal complaint addresses the dismissal itself, while separate monetary complaints can concern unpaid wages, vacation pay, termination pay, severance pay and other amounts, each subject to current procedural requirements and time limits. Prepare a separate financial schedule showing what was paid on termination, what remains claimed and the documents supporting each amount.

Do not assume the unjust dismissal complaint automatically preserves every money claim. Related reprisal, leave or other protected-right issues may also use distinct routes. The same factual event can be relevant to more than one process, but each remedy should be connected to its proper statutory mechanism. Review the current federal complaint categories and forms before filing. This prevents a wage or retaliation claim from disappearing inside a narrative focused on dismissal fairness.

Organize performance and disciplinary evidence by allegation

If the employer relies on misconduct or performance, make a table with alleged incident, date, policy or expectation, employer evidence, employee response, prior warning and outcome. Include favourable and adverse records. Preserve invitations to disciplinary meetings, investigation questions, notes, warning letters, performance plans and any written response. If a warning was disputed at the time, retain that contemporaneous objection rather than drafting the first response only after dismissal.

Use documents the employee is entitled to retain or may lawfully obtain. Do not take unrelated confidential employer data. If important records remain solely with the employer, identify them in the complaint file. If coworkers may have relevant knowledge, note the factual topic and contact details where appropriate without scripting their evidence. The evidence file should be focused enough that each allegation can be checked without searching an entire personnel history.

Treat constructive dismissal as a fact-sensitive issue

Federal guidance recognizes that unjust dismissal can include constructive dismissal. If that route is relied on, record the specific change to employment terms, when it was communicated, the prior arrangement, employee response and practical impact. Changes to compensation, duties, location, hours or another essential term may be relevant depending on the facts, but the legal conclusion should not be assumed merely because the change was unwelcome. Preserve the original contract, amendments, pay records and communications.

Record whether the employee protested, sought clarification, continued working temporarily or accepted any part of the new arrangement. The date on which a constructive dismissal is said to have occurred can affect the 90-day period, so obtain case-specific advice where timing is unclear. In the complaint, state the concrete changes and chronology first and the legal characterization second. A label does not replace evidence of what actually changed.

Prepare a loss and mitigation ledger

Where compensation may be sought, maintain a contemporaneous ledger of pre-dismissal earnings, termination payments, replacement earnings, periods without work and reasonable job-search activity. Federal guidance identifies compensation, reinstatement and other fair measures among possible remedies if unjust dismissal is established. A transparent ledger lets the eventual decision-maker see the actual financial consequence rather than a round number selected at the beginning of the complaint.

Keep applications, interview records, job offers, new pay statements and relevant benefit records. If an employment opportunity is declined, note the reason. Reconcile termination pay, severance or settlement payments already received so they are not counted twice. Keep financial loss distinct from other alleged consequences that may require a separate legal basis. The requested remedy should be reproducible from documents even though no particular remedy is automatic.

Complete the current Labour Program complaint form consistently

Use the current official federal complaint form and instructions. Make the employer name, employment dates, dismissal date and contact information match the source records. State the jurisdiction and threshold eligibility facts clearly. Present the dismissal dispute in numbered points and attach an indexed set of the termination document, contract, key disciplinary or performance records, written reasons and other records that directly address the complaint.

Do not turn the complaint form into a complete trial brief. The Labour Program should be able to verify jurisdiction, timeliness, eligibility and the central dispute quickly. Number additional pages and cross-reference exhibits. Keep a signed copy and proof of submission. If a representative is involved, complete any required authorization separately. Review the form immediately before filing because administrative requirements and submission channels can change.

Understand the mediation and Board referral stages

Canada.ca states that the Labour Program first attempts to resolve unjust dismissal complaints and that this may include mediation. If the parties do not participate in mediation or cannot resolve the complaint, the Head of Compliance and Enforcement sends the complaint to the Canada Industrial Relations Board for hearing and determination. Keep mediation material separate from the factual evidence file and observe any confidentiality requirements that apply.

If the matter is referred, retain the original complaint, employer response, written reasons and every procedural communication. Update the issue list to show what remains disputed after any partial agreement. Do not treat failed mediation as evidence that either side lacks merit. Once the Board gives directions, its filing dates and evidential requirements become the operative timetable and should be entered immediately in the case calendar.

Describe the requested remedy without promising an outcome

Official federal guidance says the Board may order compensation, reinstatement and other fair measures if it finds an unjust dismissal. The complaint may identify the remedy sought, but should not state that reinstatement or a particular financial award is automatic. If reinstatement is requested, explain the employee’s current practical position and preserve evidence relevant to whether returning to work is feasible. If reinstatement is not sought, identify the alternative relief requested.

Reconcile the requested compensation with the loss ledger and any payment already received. If another proceeding or settlement exists, record it so overlap and double recovery can be assessed. Avoid copying a remedy section from an unrelated case. The facts of the employment, the consequences of dismissal and the statutory decision-maker’s powers should drive the requested relief.

Maintain the complaint record after filing

Keep every acknowledgment, request from the Labour Program, employer submission, mediation notice, referral document and Board direction. Enter deadlines immediately. If the employer provides a new statement of reasons, add it to the chronology and compare it with earlier explanations. If new evidence emerges, preserve its source and date rather than altering the original complaint package. This keeps the administrative history auditable.

If settlement occurs, retain the signed terms, payment dates, release language and any withdrawal instruction. If the Board issues a decision, preserve the full decision and proof of compliance with every order. A complaint may remain active for months, so disciplined post-filing records prevent the case from depending on memory or informal messages.

Perform a final threshold audit immediately before submission

Before filing, verify federal jurisdiction, at least 12 consecutive months of employment, dismissal status, collective-agreement position, manager status and the 90-day calculation. Compare the dismissal date on the form with the termination document. Resolve inconsistencies before submission. A threshold defect can prevent the merits from being considered, so this final check is more important than adding another page of argument.

Then check the evidence index, chronology, loss ledger, current form version and proof-of-submission plan. Remove duplicate attachments and identify disputed facts accurately. If constructive dismissal, manager status or interaction with another process remains uncertain, obtain advice before the deadline rather than delaying until every evidential issue is perfect. Protecting jurisdiction and timeliness comes first.
