How to Dispute a Payroll Error in Canada
Follow these steps to resolve a payroll discrepancy calmly and keep a clear paper trail.

Short answer
Start by reviewing your pay stub carefully to identify the specific discrepancy. Then raise it in writing with your employer's payroll team. If payroll cannot resolve it, escalate to HR or management. For unresolved wage issues, your provincial employment standards office handles complaints, and the CRA or Revenu Quebec handles tax-related deduction errors. Material disputes may benefit from advice from a qualified professional or employment lawyer.
Discovering what looks like a payroll error can be unsettling. Before assuming the worst, it helps to work through the issue calmly and methodically. Most payroll discrepancies have straightforward explanations, and many are resolved quickly once payroll is informed.
This guide walks through the practical steps in order. Each step gives you useful information for the next one, and keeping a written record throughout protects you if the matter takes longer to resolve.
What this page helps you check
- Whether the discrepancy is in gross pay, a specific deduction, vacation pay, or net pay
- Whether a recent event (raise, job change, benefit election) could explain the difference
- Whether the issue appears on one stub or across multiple pay periods
- Whether year-to-date totals are also affected
- Whether you have saved or printed the stub showing the discrepancy
- Whether you have a record of what you expected to be paid (offer letter, contract, or prior stub)
- Whether you have already raised the issue verbally and if so what response you received
Step 1 – Review your pay stub in detail
Before contacting anyone, compare your stub line by line against what you expected. Check gross pay, each deduction, and net pay separately. If you have previous stubs or an offer letter, compare against those.
Write down the specific amount that looks wrong, the pay period it relates to, and what amount you believe is correct. A clear written note will make every subsequent conversation faster and easier.
Step 2 – Contact payroll in writing
Your first step is to contact your employer's payroll team. Do this in writing, even if that just means sending an email after a verbal conversation. Briefly describe the discrepancy, the pay period, and the amount involved.
Ask payroll to confirm how the amount was calculated and to explain any items you do not recognise. Most errors at this stage are administrative and are corrected on the next pay run. Keep a copy of every message you send and receive.
Step 3 – Escalate to HR or management if needed
If payroll confirms the calculation is correct but you still believe there is an error, or if payroll does not respond within a reasonable time, bring the matter to your HR representative or direct manager.
Present the same written summary you prepared in Step 1. Ask for a written response explaining the employer's position. At this point you are building a record that will be useful if the dispute escalates further.
Step 4 – Contact your provincial employment standards office for wage issues
If the dispute involves unpaid or underpaid wages, vacation pay, or a deduction your employer made without legal authority, and your employer has not resolved it, your provincial or territorial employment standards office is the appropriate next step.
Each province has its own employment standards legislation and a government body that administers it. You can file a complaint without needing a lawyer. There are time limits for filing, which vary by province, so it is worth acting promptly. The office can investigate your complaint and order an employer to pay outstanding amounts in some circumstances. This does not guarantee a specific outcome; the office assesses each case on its facts.
Step 5 – Contact the CRA or Revenu Quebec for deduction errors
If the dispute relates specifically to how income tax, CPP, or EI was calculated or remitted, rather than to your gross pay or vacation, the CRA (or Revenu Quebec in Quebec) may be the appropriate contact.
The CRA has a process for workers who believe their employer has not properly remitted deductions or has deducted amounts incorrectly. You can also review your employer-filed slips through My Account on the CRA website to see whether what was filed matches what appeared on your stub.
Step 6 – Consider professional advice for material disputes
For disputes involving significant amounts, wrongful deductions, or situations where your employer is unresponsive or hostile, getting advice from a qualified professional is worth considering. An employment lawyer or a qualified payroll advisor can assess your specific situation, explain your options, and help you decide how to proceed.
This guide is a general information resource, not legal or payroll advice. Provincial rules differ, and the facts of your situation matter. A qualified professional can give you guidance tailored to your circumstances.
Province & territory note
Quebec works differently
Common red flags worth checking
These do not automatically mean there is an error. They are simply lines worth a closer look, or worth asking payroll to explain.
The same error appears on multiple consecutive stubs
A recurring discrepancy suggests a systemic coding issue rather than a one-time mistake. Document each affected stub and raise the cumulative impact when you contact payroll.
Deductions were taken with no line-item explanation
Employers generally cannot make deductions from your pay without legal authority or your written consent. An unexplained deduction is worth asking about specifically.
Payroll is unresponsive after two or more written requests
If you have raised the issue clearly in writing and have not received a substantive response, escalation to HR and then to the employment standards office becomes more appropriate.
You were paid in cash with no stub provided
Employers in most provinces are required to provide a written pay statement. If you are not receiving stubs, you may have difficulty reconstructing your pay history. Keep your own records of hours worked and amounts received.
Your gross pay does not match an agreed raise or contract rate
If a pay increase was agreed in writing and has not appeared after the effective date, that is a wage shortfall. Raise it with payroll in writing and reference the agreement or correspondence confirming the increase.
Overpaid amounts are being recovered too quickly
If your employer overpaid you and is recovering the amount, they must generally have your agreement on the recovery schedule. A recovery that causes hardship or was not discussed may be worth raising with HR.

What to ask payroll or HR
Calm, specific questions get clearer answers. You can copy any of these, or build a full message with the Payroll Message Generator.
- “Can you explain how the gross pay for the [date] pay period was calculated? I was expecting [amount] based on [reason].”
- “This deduction appears on my stub but I do not recognise it. Can you confirm what it is, the amount, and under what authority it was taken?”
- “I have raised this issue in previous pay periods and it has not been corrected. Can you confirm the expected correction date?”
- “Can you provide a written explanation of your position so I have a record for my files?”
- “If I file a complaint with the employment standards office, will this affect the employer's willingness to resolve the matter directly?”
- “Is there an internal dispute or grievance process I should follow before contacting an external body?”
Frequently asked questions
Do I have to wait for my employer to fix an error before I can file a complaint?
Most employment standards offices expect you to have raised the matter with your employer first, but you do not need to wait indefinitely. If you have made reasonable attempts to resolve the issue without success, you can file a complaint. There are time limits, so do not wait too long.
What records should I keep when disputing a payroll error?
Keep copies of all pay stubs related to the dispute, any written communications with payroll or HR, any agreement about your pay rate (offer letter, contract, or written confirmation of a raise), and notes of any verbal conversations with dates and who you spoke to.
Can my employer fire me for raising a payroll error?
Employment standards legislation in most provinces prohibits retaliation against employees who exercise their rights, including raising pay complaints. If you believe you experienced retaliation, note the timeline carefully and consider getting advice from an employment lawyer or the employment standards office.
What if my employer admits the error but says it will be corrected next pay period and never is?
Document the admission in writing if possible, and follow up in writing after the next pay period if the correction does not appear. A pattern of unfulfilled commitments strengthens your case if you eventually need to involve the employment standards office.
Is there a cost to filing an employment standards complaint?
Filing a complaint with your provincial employment standards office is generally free. Employment lawyers charge fees, which vary widely. Some offer initial consultations at reduced cost or free of charge, and some take wage claims on a contingency basis.
The error is very small. Is it still worth disputing?
That is your decision. Small errors are worth raising briefly with payroll because they can signal a larger coding issue. However, the effort involved in escalation should be proportionate to the amount and your broader situation.
My employer owes me money from several years ago. Can I still claim it?
Limitation periods for employment standards complaints are set by provincial legislation and are typically one to two years, though this varies. Older claims may fall outside the recoverable window. An employment lawyer or the employment standards office can advise on the specific limit in your province.
Can the employment standards office recover my money directly from my employer?
Provincial employment standards offices can investigate complaints and, in some circumstances, order employers to pay outstanding wages. However, outcomes depend on the facts of each case, the jurisdiction, and the employer's circumstances. Filing a complaint does not guarantee recovery.
