Why Employment Record Retention Matters
Employment record-keeping isn’t an administrative nicety — it’s a statutory obligation in Ontario. The Employment Standards Act (ESA), Occupational Health and Safety Act (OHSA), Pay Equity Act, and Pay Transparency Act 2026 all impose distinct record-keeping obligations. When a Ministry of Labour officer arrives for an inspection, or when an employee files an ESA or HRTO complaint, your records are your evidence. Without them, the law often presumes in the employee’s favour.
Ontario employers are frequently surprised to learn that the obligation isn’t just to keep records — it’s to keep them in a form that is readily available for inspection. Records buried in an offsite warehouse, locked in a former employee’s personal drive, or simply never created are all treated the same way: non-compliance.
ESA Record-Keeping Requirements
Part XI of the Employment Standards Act (sections 15–15.3) sets out the core record-keeping obligations. These apply to all Ontario employers regardless of size — there is no small-employer exemption for most record categories.
Who must keep records: employers, temporary help agencies, clients of temporary help agencies, and recruiters each have distinct obligations. Job posting platform operators are also covered by provisions added by the Working for Workers Acts.
Core Employee Information
Every employer must keep records of each employee’s name, address, and employment start date for three years after the employee stops working. For students under 18, the date of birth must also be recorded and retained until three years after they turn 18 or leave employment — whichever comes first.
Hours of Work and Pay Records
| Record Type | What Must Be Recorded | Retention Period | Notes |
|---|---|---|---|
| Hours worked — hourly and variable employees | Dates, times, and hours worked in each day and each week | 3 years after the day or week of work | Daily and weekly obligation — not just payroll period-end |
| Hours worked — salaried employees (no overtime variation) | Only hours exceeding 44/week or 8/day need be recorded | 3 years | Exception applies only to genuinely fixed-schedule employees with no overtime variation |
| Pay records | Gross and net wages, pay rate, deductions (reason and amount), pay period dates | 3 years after the pay period | Deductions must be itemized — “payroll taxes” alone is insufficient |
| Overtime averaging agreements | Copy of each written agreement | 3 years after last day worked under the agreement | Verbal averaging agreements are not valid under the ESA |
| Excess hours agreements | Copy of each written agreement (for weeks 48–60) | 3 years after last day worked under the agreement | Employees can revoke with 2 weeks’ written notice |
| Multiple pay rate records | For employees working at two or more pay rates: dates, times, and regular rate for each overtime hour | 3 years | Common failure: sales roles with different hourly rates for different duties |
Pay statement obligation: Every pay period, employers must provide employees with a written pay statement showing pay period dates, regular and overtime hours, pay rate, gross and net wages, and an itemized list of deductions. The data underlying these statements must be retained for 3 years.
Vacation Records — 5-Year Retention
Vacation records have a 5-year retention requirement — longer than most other ESA records. Employers must record and retain:
- Vacation time earned by the employee in each vacation entitlement year
- Vacation time taken in each year
- Vacation time outstanding (banked) at the end of each entitlement year
- Vacation pay earned in each entitlement year
- Vacation pay paid to the employee in each entitlement year
These records must be created within seven days of the start of the next vacation year, or within seven days of the next pay day, whichever is later. The most common vacation record failure: employers who track vacation days but not the underlying vacation pay calculation. Employers must demonstrate the mathematical basis for vacation pay amounts, not just the days taken.
Leave Records
Ontario’s ESA includes 19 job-protected leaves, and employers must retain records for each. All notices, certificates, agreements, and related correspondence for each leave type must be kept for three years after the day on which the leave expired.
| Leave Type | Records to Retain | Retention Period |
|---|---|---|
| Pregnancy Leave / Parental Leave | Employee notice, medical certificate (if requested), return-to-work documentation | 3 years after leave expires |
| Family Medical Leave / Caregiver Leave | Employee notice, Compassionate Care Benefits eligibility documentation | 3 years after leave expires |
| Sick Leave (3 days unpaid) | Employee notice or request; note — employers cannot require a doctor’s note since October 2024 for these days | 3 years after leave expires |
| Long-Term Illness Leave (27 weeks — effective June 2025) | Employee notice, medical documentation confirming the condition | 3 years after leave expires |
| Domestic or Sexual Violence Leave | Employee notice; supporting documentation voluntarily provided (employer cannot require specific document types) | 3 years after leave expires |
| Bereavement Leave | Employee notice; any supporting information provided | 3 years after leave expires |
| All other ESA leaves | Notice, certificates, agreements, and correspondence | 3 years after leave expires |
Sick note ban (October 2024): Employers can no longer require medical notes from employees taking the 3 days of unpaid sick leave under the ESA. Do not build a record-keeping system that conditions leave on a note you are not entitled to require.
Job Posting and Interview Records (New — Pay Transparency Act 2026)
Effective January 1, 2026, employers with 25 or more employees have new record-keeping obligations under the Pay Transparency Act 2026 that run alongside ESA requirements.
| Record Type | What Must Be Retained | Retention Period | Who Must Keep It |
|---|---|---|---|
| Job postings | Copy of every publicly advertised job posting and any associated application form | 3 years after the posting is removed from public access | Employers with 25+ employees |
| Post-interview notifications | Records showing candidates were informed about the hiring decision within 45 days of their interview | 3 years after notification provided | Employers with 25+ employees |
| Compensation range disclosures | Evidence of the compensation range disclosed in each posting | 3 years after posting removed | Employers with 25+ employees |
Practical approach: archive all job postings as PDFs or screenshots at time of posting, with date stamps. Maintain date-stamped candidate notification emails. Store both in a dedicated recruitment records folder by posting date.
Required Policy Records
| Policy | Records Required | Retention Period |
|---|---|---|
| Disconnecting from Work Policy | Copy of each version of the policy | 3 years after the policy is no longer in effect |
| Electronic Monitoring Policy | Copy of each version of the policy | 3 years after the policy is no longer in effect |
| Tip Sharing Policy | Copy of each version and any distribution records | 3 years after the policy is no longer in effect |
| Public holiday substitution agreements | Written statement: holiday being substituted, substitute date, date provided to employee | 3 years |
| Extended temporary layoff agreements (Nov 2025) | Copy of each written agreement and Director approval if applicable | 3 years after agreement expires |
OHSA Record-Keeping Requirements
The OHSA imposes record-keeping obligations that run parallel to ESA requirements and are enforced by separate Ministry of Labour health and safety inspectors.
| Record Type | Authority | What Must Be Kept | Retention Period |
|---|---|---|---|
| JHSC meeting minutes | OHSA s.9(30) | Minutes of every JHSC meeting: attendance, agenda, issues raised, action items | No statutory period specified — best practice: minimum 5 years |
| JHSC inspection records | OHSA s.9(26) | Records of monthly workplace inspections | Best practice: minimum 5 years |
| Injury and illness records (Form 7 copies) | WSIA / OHSA | Employer copy of every WSIB Form 7 filed | 5 years from date of injury |
| Critical injury records | OHSA s.51 | Ministry notice, investigation report | Indefinite — prosecutions can arise years later |
| Workplace harassment investigation records | OHSA s.32.0.7 | Investigation records and outcome communications to both parties | Best practice: minimum 5 years given HRTO timelines |
| WHMIS training records | O.Reg. 860 | Worker name, training date, trainer, topics covered, competency confirmation | 3 years or duration of exposure — whichever is longer |
| Working at Heights training records | O.Reg. 297/13 s.26.2 | Worker name, MLTSD-approved provider, date, expiry | Duration of employment plus 3 years |
| Washroom cleaning records | ESA s.21.4 (Bill 190, July 2025) | Date and time of the two most recent washroom cleanings | Accessible to workers on request; best practice: 1 year rolling |
Pay Equity Records
The Pay Equity Act imposes ongoing record-keeping obligations on Ontario employers with 10 or more employees, administered by the Pay Equity Commission.
- Pay equity plan: Employers with 10+ employees must create and maintain a pay equity plan, post it in the workplace, and keep it current as job classes change. There is no expiry date — this is an ongoing, proactive obligation since the 2018 amendments.
- Wage records: Employers must be able to demonstrate the job rate for every job class used in the pay equity calculation. These records must remain accessible for as long as the plan is active.
- Best practice: Retain archived versions of the pay equity plan for a minimum of 7 years to demonstrate compliance history in a Pay Equity Commission audit.
Privacy Obligations for Personnel Files
The federal Personal Information Protection and Electronic Documents Act (PIPEDA) governs how Ontario private-sector employers handle employee personal information, in the absence of a substantially similar Ontario private-sector privacy statute.
| Privacy Obligation | What It Means in Practice |
|---|---|
| Data minimization | Collect only what you actually need. A SIN for payroll — yes. A photocopy of the SIN card — no. A functional abilities form — yes. A diagnosis — no. |
| Employee access to own records | Employees have the right to request access to their personal information. Respond within 30 days. References and management opinion files may be withheld; most personnel file information is accessible. |
| Third-party disclosure | Personal information should not be disclosed without the employee’s consent, except where required by law (CRA, Ministry of Labour, WSIB, court order). Reference checks require employee authorization. |
| Retention after employment ends | PIPEDA requires retention only as long as reasonably necessary. ESA and limitation period requirements typically determine the minimum retention floor. |
| Data security | Personnel files must be secured — locked physical files or password-protected digital records with access limited to those who need it. |
| Data residency | U.S.-based HRIS platforms may expose employee data to U.S. legislation (Patriot Act). Employees must be informed; for sensitive records (health, leave), Ontario data residency is strongly recommended. |
Employment Contracts and Termination Records
Termination-related records warrant longer retention because of Ontario’s civil limitation periods.
| Record Type | Recommended Retention | Reason |
|---|---|---|
| Original signed employment contract | Duration of employment plus 6 years | Ontario’s general limitation period for civil claims is 2 years from discovery; wrongful dismissal claims can arise years after termination |
| Termination letter and notice | 6 years after termination | Wrongful dismissal claims; Ministry ESA complaints |
| Termination pay calculation worksheet | 6 years after termination | ESA complaint defence; CRA payroll audit |
| Severance pay calculation | 6 years after termination | ESA s.64 triggers must be demonstrable |
| Signed release or settlement agreement | 6 years after signing | Release is the primary defence in a wrongful dismissal claim |
| Record of Employment (ROE) | 6 years after issued | Service Canada audit requirement |
| Progressive discipline records | Duration of employment plus 3 years | Relevant to ESA complaints and wrongful dismissal claims |
| Performance reviews | Duration of employment plus 3 years | Evidence in wrongful dismissal and HRTO proceedings |

Digital vs Physical Records
The ESA does not prescribe a physical format. Records can be stored digitally, provided they meet the “readily available” standard — meaning they can be produced promptly in a readable format when a Ministry officer requests them.
- Readily available means accessible on request. Records must be producible without delay — not “in the system somewhere” or “at our offsite facility.” HRIS-based records that can be exported and printed on demand satisfy this standard well.
- Backups are required. Digital records require backup procedures. Records lost in a system failure are still records you were legally required to keep — the system failure is not a defence.
- Migration obligations. When changing HRIS or payroll systems, historical records must migrate or be retained separately. Decommissioning the old system does not terminate the retention obligation.
- Employee access to digital records. PIPEDA access requests mean you need a process to produce employee personal information in a readable format within 30 days. HRIS platforms with employee self-serve portals handle this effectively.
Penalties for Non-Compliance
| Violation | Legislation | Potential Consequence |
|---|---|---|
| Failure to keep ESA records | ESA Part XI | Order to Pay (employee’s claimed amount presumed correct); administrative penalty $250–$1,000; personal director liability |
| Failure to produce records on inspection | ESA s.88 | Order to produce; refusal = contempt; prosecution up to $100,000 (corporation) |
| Failure to keep Pay Transparency job posting records | Pay Transparency Act 2026 | Director liability up to $100,000 per violation |
| Failure to keep OHSA records | OHSA | Up to $1.5 million (corporation) / $100,000 (individual director) per offence |
| Failure to maintain pay equity records | Pay Equity Act | Pay Equity Commission order; retroactive pay adjustments with no cap |
The “presumed correct” rule: When an employer fails to keep records the ESA requires, and an employee makes a wage claim for the period when no records exist, the Ministry Officer may presume the employee’s account of hours and wages is correct. This shifts the burden entirely to the employer — and without records, there is typically nothing to rebut the claim.
8 Common Record-Keeping Mistakes
| # | Mistake | Consequence | Risk Level |
|---|---|---|---|
| 1 | Keeping vacation records for 3 years instead of the required 5 | Incomplete records for ESA vacation pay claims and Ministry inspections in years 4–5 | Medium — ESA violation |
| 2 | Not retaining job posting records (25+ employers, Pay Transparency Act 2026) | Director liability up to $100,000 per violation; inability to defend a Pay Transparency complaint | High — $100K director liability |
| 3 | Not recording hours for salaried employees with overtime variation | The salaried exception applies only to genuinely fixed-schedule employees; without records, Ministry presumes employee version correct | Medium-High |
| 4 | Not retaining JHSC minutes or keeping them for too short a period | Cannot demonstrate OHSA compliance in an inspection or prosecution | Medium — OHSA violation |
| 5 | Discarding employment contracts when an employee leaves | No record of the termination clause you’re relying on in a wrongful dismissal claim | High — direct wrongful dismissal exposure |
| 6 | Storing all employee records in a single unencrypted location | Data breach affects all personnel files simultaneously; PIPEDA breach notification obligation | High — reputational and legal exposure |
| 7 | Not archiving old policy versions when updates are made | Cannot demonstrate the policy was in effect at the time of a relevant event (e.g., harassment complaint, monitoring disclosure) | Medium |
| 8 | Assuming the limitation period starts on the termination date | Ontario’s 2-year civil limitation period runs from discovery of the claim — which can be years after termination; records discarded too early leave you without a defence | High — common law claim exposure |
Frequently Asked Questions
How long must Ontario employers keep payroll records?
Under the ESA, payroll records — including pay rates, gross and net wages, deductions, and pay period dates — must be kept for three years after the pay period to which they relate. This is a minimum. CRA payroll audits can cover the past six years, so most employers retain payroll records for six years to align with CRA’s audit period. For any record connected to a potential wrongful dismissal claim, six years is the practical minimum retention.
Why do vacation records have a 5-year retention requirement when most ESA records are 3 years?
The ESA explicitly sets a 5-year retention period for vacation records — time earned, time taken, outstanding balance, and vacation pay calculations. The longer retention reflects the complex accrual nature of vacation entitlements and the frequency with which vacation pay calculation disputes arise. An employee can raise a vacation pay complaint for a period that would fall outside the 3-year window for most other records, so the extended retention period protects both employers and employees.
Are Ontario employers required to keep records of every job posting as of 2026?
Yes, if they have 25 or more employees. Effective January 1, 2026, the Pay Transparency Act 2026 requires employers with 25 or more employees to retain a copy of every publicly advertised job posting and any associated application form for three years after the posting is removed from public access. This obligation applies to external postings — not internal-only postings — and to employers at or above the 25-employee threshold on the date the posting was made.
Can Ontario employment records be kept in digital format?
Yes. The ESA does not require physical records. Digital records are fully compliant provided they meet the “readily available” standard — meaning they can be produced promptly in a readable format when a Ministry officer requests them. Records must be backed up, secured against unauthorized access, and preserved if you change HRIS or payroll systems. Losing records in a system failure does not satisfy the retention obligation.
How long should an employer keep a terminated employee’s personnel file?
The ESA minimum is three years after employment ends for most records (five years for vacation records). However, wrongful dismissal claims rely on the employment contract and can be discovered years after termination. Ontario’s civil limitation period runs from the date the claim is discovered, not the termination date. Best practice is to retain the complete personnel file — signed employment contract, termination documentation, and performance or discipline records — for six years after employment ends.
Does an employee have the right to see their own personnel file in Ontario?
Under PIPEDA, employees of Ontario private-sector employers have the right to request access to their personal information, which includes most of what is in a personnel file. The employer must respond within 30 days. Certain categories may be withheld — references from third parties, solicitor-client privileged material, or management opinion documents that would reveal information about other individuals. The ESA itself does not create an express right of access to employment records, but PIPEDA effectively does for most employees in private-sector workplaces.
