HR Audit Checklist: How to Review Your HR Function and Find What’s Costing You

TLDR: An HR audit is a structured review of your employment policies, records, compliance, and HR processes to find gaps before they become problems. For most small and mid-size businesses, the highest-risk areas are employee files, payroll accuracy, employment contracts, and the employee handbook. You don’t need to hire a law firm to run a useful audit — but you do need to be systematic. This guide walks through exactly what to look at and why.

Most businesses don’t think about HR compliance until something goes wrong. A wrongful dismissal claim. A Ministry of Labour audit. A departing employee who points out that their offer letter never matched how they were actually paid. By then, the cost of fixing the problem is usually higher than the cost of preventing it would have been.

An HR audit changes that dynamic. Instead of waiting for a complaint or an investigation to surface your gaps, you go looking for them yourself — on your own schedule, with time to fix things properly.

This guide covers what an HR audit actually involves, which areas matter most for Ontario businesses, and a practical checklist you can work through whether you’re doing this internally or bringing in outside help.

What Is an HR Audit?

An HR audit is a systematic review of your organization’s HR policies, practices, documentation, and employment relationships to assess legal compliance and operational effectiveness. It’s not a pass/fail test. It’s a diagnostic — a way of understanding where your HR function is strong, where it’s weak, and where you’re carrying legal or operational risk you might not be aware of.

HR audits can be broad (covering everything from hiring to offboarding) or targeted (focusing on a specific area like payroll compliance or termination practices). Most businesses benefit most from starting broad — running a general audit to identify where the biggest gaps are — and then going deep on the highest-risk areas.

The goal isn’t perfection. It’s risk reduction. And in Ontario, where employment law obligations are more extensive than most business owners realize, the gaps tend to be significant.

When Should You Run an HR Audit?

For most small and mid-size businesses, running a comprehensive HR audit once a year is a reasonable baseline. But there are specific events that make an audit especially timely:

• You’ve grown quickly. Businesses that go from 10 to 30+ employees often do so faster than their HR infrastructure can keep up. Policies that were informal at 10 people become compliance liabilities at 30.
• You’ve never done one. If you’ve been operating for two or more years without reviewing your HR documentation and practices, there are almost certainly issues.
• You’re bringing in outside HR support. If you’re onboarding a fractional HR partner or an HR consultant, an audit is usually their first step — and having one already done saves time and money.
• You’ve had a termination or complaint. Employment disputes have a way of surfacing systemic problems. An audit after a contentious departure can prevent the next one.
• Employment law has changed. Ontario’s Employment Standards Act has been amended multiple times in recent years. If your handbook and contracts haven’t kept up, you may have provisions that are now unenforceable or non-compliant.

The HR Audit Checklist: 8 Core Areas

1. Employment Contracts and Offer Letters

This is the highest-risk area for most Ontario employers and the one that generates the most expensive claims when it goes wrong.

• Does every employee have a signed offer letter or employment agreement?
• Do contracts correctly limit termination entitlements, or do they leave you exposed to common law reasonable notice (which can be months or years of salary)?
• Are the termination clauses up to date with current case law? Several previously standard clauses have been struck down by Ontario courts in recent years.
• Do contracts correctly classify employees vs. independent contractors? Misclassification is a significant ESA and tax risk.
• Are any fixed-term contracts at risk of implied indefinite status?

Employment contracts are one area where you want a legal review, not just an internal one. The cost of a lawyer reviewing your template agreements is minimal compared to a wrongful dismissal claim based on a defective termination clause.

2. Employee Files and Record-Keeping

• Does every employee have a personnel file? Is it stored securely and separately from medical information?
• Do files contain signed offer letters, signed policy acknowledgments, completed SIN documentation, and tax forms?
• Are performance issues documented? Informal conversations that were never written down often become problems during termination disputes.
• Are compensation changes and title changes documented with dates?
• Are records retained for the required period? Ontario generally requires retention of employment records for three years after employment ends.

3. Employee Handbook and Policies

• Is there a current employee handbook, and is it dated?
• Does the handbook reflect how you actually operate — remote work, hybrid policies, PTO, disciplinary procedures?
• Are the following policies included: harassment and workplace violence (required under OHSA), accommodation and AODA, privacy, social media, and discipline/termination?
• Do employees acknowledge the handbook in writing? Without signed acknowledgments, the handbook is difficult to rely on in disputes.
• When was the handbook last updated? If it predates the pandemic or recent ESA amendments, it likely needs a review.

The employee handbook creation process is one of the most common fractional HR engagements — because most businesses have a handbook that hasn’t been touched in years.

4. Payroll and Compensation Compliance

• Are all employees classified correctly (full-time, part-time, casual, contractor)?
• Are overtime calculations correct? Ontario’s ESA has specific rules about overtime thresholds and averaging agreements that are frequently misapplied.
• Are all statutory deductions (CPP, EI, income tax) being made and remitted correctly?
• Are employees receiving all mandatory ESA entitlements: vacation pay (minimum 4% or 6%), public holiday pay, and statutory leaves of absence?
• Are wages meeting Ontario’s current minimum wage requirements?
• Are there any employees being paid commission, tips, or bonuses? Are those arrangements documented in writing?

5. Hiring and Onboarding Practices

• Are job postings compliant with the Ontario Human Rights Code? Job ads cannot specify age, gender, national origin, or other protected grounds.
• Are interview questions screened for prohibited grounds of discrimination?
• Are reference and background check procedures documented and consistent?
• Is there a formal onboarding checklist? Inconsistent onboarding is one of the most common early retention problems.
• Do new hires receive required notices under the ESA?

6. Health and Safety

• Does the workplace have a Joint Health and Safety Committee (JHSC) if required? In Ontario, workplaces with 20+ employees must have a JHSC.
• Are workplace violence and harassment policies posted and distributed as required under the OHSA?
• Are incident reports being completed and retained?
• Are employees trained on workplace safety procedures?
• Is the WSIB account registered and up to date?

7. Leaves of Absence

Ontario’s ESA provides for an extensive range of statutory leaves — and many employers aren’t administering them correctly, particularly the ones added or expanded in recent years.

• Are employees being granted their full entitlement to pregnancy and parental leave?
• Are employees aware of — and being granted — sick leave, family responsibility leave, bereavement leave, domestic violence leave, and infectious disease emergency leave?
• Are leaves being tracked and documented?
• Is the company meeting obligations related to benefits continuation during leaves?

8. Termination and Offboarding

• Are termination decisions documented with business reasons?
• Are proper notice or pay in lieu of notice calculations being made under the ESA?
• Are separation agreements being used for higher-risk terminations? Are they being reviewed by a lawyer before being presented to employees?
• Is the offboarding process consistent — access revocation, equipment return, final pay timing?
• Are Record of Employment (ROE) forms being filed correctly and on time with Service Canada?

What Happens After the Audit?

The audit itself is only useful if it leads to action. Once you’ve worked through the checklist, the next step is prioritizing what you found. Not everything needs to be fixed immediately. A practical framework:

1. Legal exposure first. Defective employment contracts, missing harassment policies, ESA underpayments — these go to the top of the list because they carry the highest financial and regulatory risk.
2. Operational consistency second. Inconsistent processes (onboarding, performance management, documentation) create problems over time but aren’t usually emergencies.
3. Infrastructure and systems third. HR technology, record-keeping systems, and reporting capabilities improve how you operate, but they’re rarely the highest-priority fix.

If the audit surfaces significant legal gaps, get employment counsel involved before making changes. Fixing a contract template the wrong way can create new problems while trying to close old ones.

Should You Run the Audit Internally or Bring in Help?

You can run a basic HR audit internally using a checklist like this one. For many small businesses, an internal review by the owner, operations manager, or HR lead is enough to surface the most obvious gaps.

The limits of internal audits are: you don’t know what you don’t know, and it’s easy to rationalize away things that are inconvenient to fix. An external HR audit — done by an HR consultant or fractional HR partner — brings objectivity, benchmarks against actual compliance requirements, and usually surfaces things an internal team would miss.

For businesses without a dedicated HR function, a fractional HR partner who conducts an initial audit is often the most cost-effective starting point. It gives you an accurate picture of where you stand and a prioritized list of what to fix — without committing to a full-time hire.

The Cost of Not Auditing

The Ministry of Labour conducts employer audits — and when they find violations, penalties include back pay, fines, and orders to comply. A single wrongful dismissal claim from an employee whose contract had a defective termination clause can cost tens of thousands of dollars. An OHSA complaint related to a missing harassment policy can result in orders, fines, and public regulatory history.

The cost of a proactive HR audit — whether internal or external — is almost always a fraction of the cost of addressing the same issues after they’ve been raised as complaints or claims.
