Pay Equity vs. Equal Pay: What's the Difference?
Director of Customer Experience, AugmentHR
Understanding compensation legislation can be challenging for business leaders and HR professionals across Ontario. Two terms often used interchangeably, Equal Pay and Pay Equity, actually refer to distinct legal concepts, governed by different statutes and enforced through separate regulatory frameworks.
Confusing the two can leave an organization vulnerable to non-compliance risks, retroactive pay penalties, and employee dissatisfaction. The following breakdown explains the differences, regulatory requirements, and how to maintain compliance under Ontario law.
What is Equal Pay?
In Ontario, Equal Pay refers to the legal standard of "Equal Pay for Equal Work."
This principle is primarily governed under Part XII (Section 42) of the Ontario Employment Standards Act, 2000 (ESA). It mandates that an employer cannot pay an employee of one sex less than an employee of another sex when both are performing substantially the same work.
Key takeaway: Equal Pay evaluates direct job-to-job equality (e.g., comparing one Financial Analyst to another Financial Analyst within the same company).
Core Criteria for Equal Pay Under the ESA
According to the Ontario Ministry of Labour, Immigration, Training and Skills Development, equal pay applies when:
Substantially the Same Kind of Work: The actual tasks performed share core duties and responsibilities, regardless of minor title variations.
Equal Skill, Effort, and Responsibility: The roles require comparable technical knowledge, education, physical/mental effort, and operational accountability.
Similar Working Conditions: The work is performed in similar operational and physical environments within the same establishment.
Allowable Exceptions Under the ESA
The ESA recognizes that legitimate pay differentials can exist between individuals performing the same job. Pay differences are permitted if they are based on:
- A formal seniority system.
- A documented merit system based on measured performance.
- A system that measures earnings by quantity or quality of production (e.g., piecework).
- Any factor other than sex (such as specific shifts or technical certifications).

What is Pay Equity?
Pay Equity refers to "Equal Pay for Work of Equal Value."
This concept is governed by Ontario’s Pay Equity Act, R.S.O. 1990, and enforced by the Ontario Pay Equity Commission (PEC) and the Pay Equity Hearings Tribunal.
Pay equity addresses systemic, historical undervaluation of female-dominated job classes compared to male-dominated job classes of comparable value within the same organization.
Key takeaway: Pay Equity compares fundamentally different jobs of equal organizational value (e.g., comparing a female-dominated HR Coordinator role to a male-dominated Warehouse Supervisor role).
Core Components of Ontario's Pay Equity Act
Applicability: The Act applies to all public sector employers and all private sector employers with 10 or more employees.
Job Class Identification: Jobs are categorized into classes based on duties, qualifications, and recruiting rates. A job class is considered female-dominated if 60% or more of incumbents are female (or historically female-dominated) and male-dominated if 70% or more are male.
Gender-Neutral Comparison Systems (GNCS): Employers must evaluate and score roles using a standardized, non-biased system assessing four mandatory factors:
- Skill: Formal qualifications, technical training, and experience.
- Effort: Physical and mental demands.
- Responsibility: Decision-making authority, supervision, and fiscal accountability.
- Working Conditions: Physical hazards, stress levels, and operational environment.
Wage Adjustments & Maintenance: If a female job class is scored equally to a male job class but paid less, the employer must increase the female wage rate to match the comparator. Pay equity is not a one-time exercise; employers have an ongoing legal obligation to maintain pay equity as organizational structures evolve.

Pay Equity vs. Equal Pay: What’s the Difference?
To clearly illustrate how these two compensation frameworks differ in Ontario, below highlights their statutory and functional distinctions:
To see how these two standards separate in practice, consider these key operational and legal differences:
Governing Legislation: Equal Pay is governed by the Employment Standards Act, 2000 (ESA), while Pay Equity is governed by the Pay Equity Act, R.S.O. 1990.
Enforcing Agencies: Equal Pay complaints are handled by the Ministry of Labour, Immigration, Training and Skills Development. Pay Equity is overseen by the Pay Equity Commission (PEC) and the Pay Equity Hearings Tribunal.
Core Principle: Equal Pay ensures equal pay for the same work. Pay Equity ensures equal pay for different work of equal value.
Comparison Basis: Equal Pay uses a direct, person-to-person comparison in matching roles. Pay Equity uses a system-wide job class evaluation to compare female-dominated and male-dominated roles.
Employer Thresholds: Equal Pay applies to every Ontario employer with 1 or more employees. Pay Equity applies to private employers with 10 or more employees and all public sector employers.
Compliance Actions: Equal Pay requires addressing individual pay gaps as they arise. Pay Equity requires proactive job evaluations, formal point scoring, and establishing a Pay Equity Plan (mandatory for employers with 100+ staff).

Strategic Steps for Ontario Employers
Navigating compensation compliance requires structured evaluation, clear documentation, and consistent compensation benchmarking. Recommended practices for HR leaders include:
Audit Existing Job Descriptions: Ensure job descriptions reflect actual current duties, required credentials, and core accountabilities rather than outdated specifications.
Establish Clear Compensation Bands: Implement market-competitive, objective salary ranges that tie compensation to documented merit, experience, and responsibility.
Conduct a Pay Equity Review: If your organization employs 10 or more people in Ontario, determine your female and male job classes and evaluate them using a compliant, gender-neutral system.
Maintain Ongoing Compliance Records: Document the rationale behind compensation adjustments, hiring offers, and yearly merit increases to support pay decisions during audits.
Whether building an initial compensation structure or conducting a comprehensive pay equity audit, leveraging specialized HR consulting ensures full regulatory alignment while maintaining competitive market positioning.
