Pay Equity in Ontario: The Gap Between Law and Practice

What Pay Equity Means

Pay equity is not the same as equal pay for equal work. Equal pay for equal work — the principle that men and women performing substantially the same job should receive the same pay — has been part of Ontario employment law since the 1950s. The Employment Standards Act, 2000 (ESA) prohibits paying an employee of one sex less than an employee of the other sex for substantially the same kind of work performed in the same establishment under the same or similar working conditions (section 42).

Pay equity goes further. It is the principle of equal pay for work of equal value — the recognition that jobs predominantly performed by women may be of equal or greater value to the employer as jobs predominantly performed by men, but are systematically underpaid because the work is historically associated with women. The comparison is not between a male nurse and a female nurse doing the same job — that is equal pay for equal work. The comparison is between a predominantly female job class (nurse) and a predominantly male job class (electrician) that the employer values equally in terms of skill, effort, responsibility, and working conditions.

The distinction is critical because occupational segregation means that men and women often do not perform the same jobs. Comparing salaries within the same job class captures individual-level discrimination but misses the structural undervaluation of entire categories of work. Pay equity legislation addresses the structural problem.

Ontario's Pay Equity Act

Ontario's Pay Equity Act, RSO 1990, c. P.7, came into force on January 1, 1988. It was one of the first proactive pay equity statutes in the world — meaning it imposed affirmative obligations on employers to achieve pay equity, rather than merely prohibiting discrimination.

Coverage

The Act applies to all employers in Ontario's public sector (regardless of size) and all private sector employers with ten or more employees. This coverage is broad: the vast majority of Ontario workers are employed by organizations subject to the Act.

The Obligation

Employers subject to the Act are required to establish and maintain compensation practices that provide for pay equity in every establishment. "Pay equity" means that the job rate for female job classes is at least equal to the job rate for male job classes of comparable value.

The obligation is proactive. The employer must identify female-dominated and male-dominated job classes within the establishment, evaluate the value of those job classes using a gender-neutral job evaluation system, compare the compensation of female-dominated job classes with male-dominated job classes of comparable value, and adjust compensation to eliminate any gap where a female-dominated job class is paid less than a male-dominated job class of comparable value.

Job Evaluation

The heart of the pay equity process is the job evaluation — the systematic assessment of the value of each job class based on the skill, effort, responsibility, and working conditions required.

Skill includes intellectual and physical qualifications acquired by education, training, or experience. Effort includes the intellectual and physical effort normally required in the performance of the job. Responsibility includes the responsibility normally required in the performance of the job, including responsibility for technical, financial, and human resources. Working conditions includes the noise, heat, cold, isolation, physical danger, health hazards, and other conditions of work.

The evaluation must be gender-neutral — the criteria and the weightings must not systematically undervalue characteristics associated with female-dominated work. Historically, job evaluation systems overvalued physical effort and hazardous working conditions (associated with male-dominated jobs) and undervalued interpersonal skills, emotional labour, and fine motor skills (associated with female-dominated jobs). The Pay Equity Act requires that the evaluation system be free of gender bias.

Comparison Methods

The Act provides two comparison methods:

Job-to-job comparison. The primary method is a direct comparison between a female-dominated job class and a male-dominated job class that has the same or comparable value. If the female-dominated job class is paid less, the employer must increase compensation to achieve pay equity.

Proportional value comparison. Where there is no male-dominated job class of comparable value — which can occur in workplaces with very few male-dominated job classes — the employer uses the proportional value method. This method establishes the relationship between the value of work and compensation in male-dominated job classes and applies that relationship to female-dominated job classes.

Implementation

The Act required employers to achieve pay equity by January 1, 1990 (public sector, with phased-in adjustments for the private sector). Once pay equity is achieved, the employer must maintain it — which means adjusting compensation when job classes change, when new job classes are created, or when compensation changes would otherwise create or widen a gap.

The Enforcement Gap

On paper, Ontario's Pay Equity Act is a powerful statute with clear obligations and enforcement mechanisms. In practice, compliance is uneven, enforcement is under-resourced, and many employers — particularly in the private sector — have not fully achieved pay equity.

The Pay Equity Commission

The Pay Equity Office (now part of the Pay Equity Commission) is responsible for administering and enforcing the Act. The Commission can receive complaints, conduct investigations, issue orders, and mediate disputes. Review Officers can enter workplaces, examine records, and require employers to produce pay equity plans.

The Commission's resources have been a persistent concern. Historically, the Commission has been understaffed relative to the volume of complaints and the number of employers subject to the Act. The result is a backlog of unresolved complaints and limited capacity for proactive enforcement.

Private Sector Compliance

Compliance in the private sector is particularly weak. Many small and medium-sized employers subject to the Act (those with ten or more employees) have never prepared a pay equity plan, have never conducted a job evaluation, and are not aware of their obligations. The Act's requirements are complex — job evaluation is a technical process that typically requires expertise in compensation analysis — and small employers may not have the resources or knowledge to comply.

The penalty for non-compliance is modest. The Act provides for prosecution of employers who fail to comply, but prosecutions are rare. The primary enforcement mechanism is the complaint process, which requires an individual employee or union to identify a pay equity violation and file a complaint with the Commission. Many employees do not know the Act exists, do not know they have the right to complain, or fear retaliation if they do.

Public Sector Compliance

Compliance in the public sector is generally better than in the private sector, in part because public sector employers are larger, have dedicated HR departments, and are more likely to have the resources to conduct pay equity analyses. Public sector unions have also been active in monitoring pay equity compliance and filing complaints when gaps are identified.

However, even in the public sector, pay equity maintenance has been a challenge. The obligation to maintain pay equity is ongoing, and changes in compensation, job classifications, and organizational structure can create or widen gaps that must be addressed. Maintaining pay equity requires continuous monitoring and adjustment, which some public sector employers have not adequately resourced.

The Gender Pay Gap: What the Numbers Show

Statistics Canada data consistently shows a gender pay gap in Ontario. As of 2023, women in Ontario working full-time, full-year earned approximately 87 cents for every dollar earned by men in the same category. For part-time workers, the gap is different (and sometimes reversed), but the full-time comparison is the most commonly cited measure.

The 13-cent gap reflects multiple factors:

Occupational segregation. Women are overrepresented in lower-paying occupations (healthcare, education, social services, retail) and underrepresented in higher-paying occupations (technology, finance, engineering, trades). This segregation is itself partly a result of the systemic undervaluation that pay equity legislation is designed to address — the jobs are lower-paying in part because they are performed predominantly by women.

Hours worked. Women are more likely to work part-time and to take career interruptions for caregiving responsibilities. This reduces average annual earnings but does not necessarily indicate a per-hour pay gap for the same work.

Experience and seniority. Career interruptions for caregiving can result in lower seniority and fewer years of experience, which reduces compensation under experience-based pay systems.

Discrimination. A portion of the gap reflects ongoing discrimination — both individual-level discrimination (paying a woman less than a man for the same or comparable work) and structural discrimination (undervaluing work performed predominantly by women).

The Pay Equity Act addresses the structural discrimination component. It cannot, by itself, solve occupational segregation, caregiving-driven career interruptions, or individual-level discrimination (which falls under the Human Rights Code and the ESA). But the component it addresses is significant, and full compliance with the Act would narrow the gap.

Intersectional Pay Gaps

The gender pay gap is wider for racialized women, Indigenous women, and women with disabilities. Statistics Canada data shows that racialized women in Ontario earn less than non-racialized women, who in turn earn less than men. Indigenous women face particularly acute pay disparities. Women with disabilities earn less than women without disabilities.

Ontario's Pay Equity Act addresses gender-based pay disparities but does not explicitly address intersectional disparities. The Act compares female-dominated and male-dominated job classes — it does not compare the compensation of racialized women to that of non-racialized women within the same job class, or the compensation of women with disabilities to that of women without disabilities.

This limitation means that the Act addresses one axis of pay discrimination (gender) but not the intersecting axes that compound the disadvantage for women who face multiple forms of marginalization. Addressing intersectional pay disparities requires a broader set of legal tools — including the Human Rights Code, employment equity programs, and targeted policy interventions — that go beyond the scope of the Pay Equity Act.

What Employees Can Do

If you believe your employer is not complying with the Pay Equity Act, you have several options:

Request your pay equity plan. Under the Act, employers are required to prepare and post a pay equity plan. You have the right to review the plan and to see how female-dominated and male-dominated job classes in your establishment were evaluated and compared.

Talk to your union. If you are unionized, your union has an important role in the pay equity process. The union participates in the development of the pay equity plan, monitors compliance, and can file complaints with the Pay Equity Commission. Raise your concerns with your union representative.

File a complaint. You can file a complaint with the Pay Equity Commission if you believe your employer has not achieved or maintained pay equity. The Commission will investigate the complaint, and if a violation is found, can order the employer to adjust compensation. There is no filing fee.

Understand the timeline. Pay equity adjustments, when ordered, are prospective — they correct the compensation going forward. The Act does not generally provide for retroactive adjustments or back pay (unlike the Human Rights Code, which can provide remedies for past discrimination). This means that delays in filing complaints result in lost compensation that may not be recoverable.

The Path Forward

Ontario's Pay Equity Act was groundbreaking when it was enacted in 1988. Its fundamental structure remains sound — proactive obligations, systematic comparison, gender-neutral evaluation. But more than three decades later, the Act's promise has not been fully realized.

Full realization requires three things: stronger enforcement by the Pay Equity Commission, with adequate resources and a willingness to pursue proactive compliance rather than relying solely on complaints; greater employer accountability, including mandatory pay equity reporting that would make compliance (or non-compliance) visible to employees, unions, and the public; and extension of the pay equity framework to address intersectional disparities, recognizing that gender-based pay inequity cannot be fully addressed without also addressing race-based, disability-based, and other forms of pay discrimination.

The Pay Equity Act gives Ontario employees a legal right to equal pay for work of equal value. That right exists today, and it is enforceable. The challenge is ensuring that more employees know about it and that the enforcement mechanisms are strong enough to make it real.
