Ontario Human Rights Code: Rights and Prohibited Discrimination in Employment

Ontario’s Human Rights Code (R.S.O. 1990, c. H.19) gives every person the right to equal treatment in employment and every employee the right to a workplace free of harassment, with no discrimination based on a defined list of protected grounds. This page explains what the Code protects and the forms discrimination can take, in plain language, and links each rule to the official source.

One idea frames everything below. The Code’s protections are a floor, not a ceiling in the sense that they reach far beyond what the law would otherwise require: the common law has no standalone duty to treat employees equally, so these are enforceable rights against discrimination — in hiring, in working conditions, and in termination — that the implied terms of an employment contract simply do not provide. The companion page covers the exceptions, special programs, and enforcement that complete the picture.

What rights does the Ontario Human Rights Code give employees?

The Code says two things plainly. First, every person has the right to be treated equally in employment, without discrimination on any of the protected grounds. Second, every employee has the right to work free from harassment tied to those grounds — whether the harassment comes from the employer, someone acting for the employer, or a co-worker.

The protected grounds for equal treatment span sixteen categories: race and ancestry; place of origin, colour, and ethnic origin; citizenship and creed; sex, sexual orientation, gender identity, and gender expression; age and record of offences; and marital status, family status, and disability.

The harassment protection covers nearly the same grounds, with one notable gap: sex does not appear in the harassment subsection (it is addressed elsewhere in the Code — see workplace harassment and sexual solicitation). The other fifteen grounds carry through intact.

“Equal treatment in employment” is broad. It reaches the whole working relationship — how a job is advertised and how people are hired, the pay and conditions set, the way people are treated day to day, and how a job ends.

Where employers trip up: thinking this is only about hiring, or only about overt bias. It also covers conduct that is not meant to discriminate but lands harder on a protected group, and it makes an employer responsible for harassment by its own staff, not just by management. In practice, a manager who lets a poisoned atmosphere fester is a Code problem, not just a culture problem.

The statute is the floor, not the ceiling. Common law has no standalone duty to treat employees equally; the Code creates enforceable rights against discrimination in hiring, working conditions, and termination that reach well beyond anything the common law’s implied employment terms provide.

What are the protected grounds under the Ontario Human Rights Code?

The protected grounds for equal treatment in employment span sixteen categories: race and ancestry; place of origin, colour, and ethnic origin; citizenship and creed; sex, sexual orientation, gender identity, and gender expression; age and record of offences; and marital status, family status, and disability. The Code also defines those terms, and several definitions are wider than common sense suggests — the definitions section is where most of the real fights happen.

A few definitions that catch employers out:

• “Age” here means 18 or older. The protection has no upper cap, so there is no age at which it is safe to treat someone differently because they are “too old.”
• “Disability” is read very broadly. It covers any degree of physical disability, mental impairment, developmental or learning disability, mental disorders, and conditions tied to a workplace-injury (WSIB) claim. Importantly, it also covers a disability someone had in the past or is merely believed to have. “Minor” or invisible conditions still count.
• Sex discrimination expressly includes being treated differently because a woman is pregnant or may become pregnant.
• “Family status” means being in a parent-and-child relationship; “marital status” covers married, single, widowed, divorced, separated, and living common-law in a conjugal relationship.
• “Harassment” is a course of vexatious comment or conduct that the harasser knew, or ought reasonably to have known, was unwelcome. Vexatious means the conduct is distressing or annoying in character — and whether the harasser meant it that way is beside the point.
• A “record of offences” ground protects pardoned criminal convictions and provincial-offence convictions, not every charge.

The Code also defines “person” broadly, reaching employment agencies, unions, associations, partnerships, and the like, so liability is not limited to the incorporated employer.

In practice, when something feels borderline, the defined term should be checked before acting; close calls are worth a quick professional read.

What is constructive discrimination?

Constructive discrimination is when a rule, requirement, or qualification that looks perfectly neutral still excludes, restricts, or gives a preference to a group identified by a prohibited ground. What matters is the effect of the rule, not the intent behind it.

No one needs to be singled out for a workplace to run afoul of the Code. A neutral-looking rule can still be discrimination if, in practice, it excludes, restricts, or gives a preference to a group identified by a prohibited ground (race, sex, creed, disability, age, and the rest). The Code calls this “constructive discrimination.”

There are limited ways out. The rule is allowed if it is reasonable and bona fide in the circumstances — a genuine operational necessity, not just convenient or traditional. It is also allowed where the Code itself says discriminating on that ground is not an infringement (with the workplace-related provision in section 17 carved out of that exception).

Here is the catch that trips employers up: a rule is not “reasonable and bona fide” just because the employer says so. A tribunal or court will not accept it unless it is satisfied the affected group cannot be accommodated without undue hardship on whoever is responsible for accommodating them. And undue hardship is measured against set factors only — cost, any outside funding available, and health and safety — plus any standards set by regulation. Inconvenience, grumbling, or a thin worry about morale does not clear that bar.

In practice, this means the duty to accommodate rides along with almost every neutral standard an employer sets, from uniform rules to scheduling to physical fitness tests. If a standard burdens a protected group, the employer must be ready to show it looked hard for an accommodation and that the only honest answer was undue hardship.

Source: Human Rights Code, s. 11.

The statute is the floor, not the ceiling. The common law won’t make an employer justify or change a neutral workplace rule just because it falls harder on a protected group. Section 11 of the Code does — it treats that disproportionate effect as discrimination and pulls in the duty to accommodate up to the point of undue hardship.

Discrimination by association and announced intention to discriminate

The Code protects people from discrimination based on their connection to someone covered by a prohibited ground, and it bars public notices or signs that signal an intent to discriminate. Most people picture discrimination as something aimed directly at the person who shares a protected trait; the Code reaches further than that.

Discrimination by association. Protection under the Code’s main rights does not only kick in when a person is themselves targeted because of a protected ground. It also kicks in when a person is treated badly because of their relationship, association, or dealings with someone else who is identified by a prohibited ground. So an employee can have a valid complaint even though the trait belongs to a family member, partner, friend, or business contact rather than to the employee.

Announced intention to discriminate. It is also a breach to publish or display to the public — or to cause such a display — any notice, sign, symbol, emblem, or similar message that signals an intention to break someone’s rights under the Code, or that is meant to stir others up to do so. The Code carves out one limit here: this rule is not meant to interfere with the freedom to express an opinion.

Where employers trip up: a job ad, posting, or workplace signage that hints at a preference tied to a protected ground can land an employer in trouble before anyone is even hired — the public message is enough. And firing or sidelining a worker because of who they are connected to is just as much a violation as targeting the worker’s own characteristics.

Workplace harassment and sexual solicitation by employers

Every employee has a right to be free from workplace harassment because of sex, sexual orientation, gender identity, or gender expression, and from sexual advances or reprisals by anyone who controls a benefit or advancement. That harassment protection covers harassment from the employer, from anyone acting as the employer’s agent, and from a co-worker.

The Code also targets something narrower and more serious: pressure from a person who holds power over someone’s job. Two things are off-limits.

• A sexual solicitation or advance made by someone in a position to bestow, grant, or deny a benefit or advancement — where that person knows, or reasonably should know, the advance is not welcome.
• A reprisal, or a threat of one, for turning down such an advance, again where the person making the threat controls a benefit or advancement.

That “knows or ought reasonably to know” standard matters: a manager cannot hide behind “I didn’t realize she minded.” If a reasonable person would have known the attention was unwelcome, that is enough.

Where employers get burned is treating this as someone else’s problem. The harassment protection reaches conduct between co-workers, not just conduct by the boss — and the employer is the one expected to keep the workplace clean. In practice, that means having a real complaint route, taking reports seriously, and never letting a supervisor’s say over raises, shifts, or promotions become leverage for unwanted advances.

Can an employer punish an employee for raising a human rights complaint?

No. The Code gives every person the right to claim and enforce their own Code rights, to start or take part in a Code proceeding, and to refuse to infringe someone else’s Code rights — all without facing a reprisal or even a threat of one. The threat alone is enough to violate the rule; no follow-through is required.

The Code gives every person three distinct protections. First, a person can claim and enforce their own rights under the Code. Second, a person can start a complaint or participate in a proceeding under the Code — that includes filing as well as being a witness or party. Third, a person can refuse to infringe someone else’s Code rights. Do any of those, and the Code says no one can respond with a reprisal, or even threaten one.

“Reprisal” just means payback — punishing someone because they spoke up. In an employment setting that might look like a demotion, sudden discipline, lost shifts, or termination. And the threat alone is enough to violate the rule — no follow-through required.

A caution about what tribunals and courts have read into this section: adjudicators have consistently held that the underlying assertion does not need to succeed for the reprisal protection to kick in. Someone who raises a Code concern and then faces adverse treatment can pursue a reprisal finding alongside — or even independently of — the merits of the original complaint. That interpretation comes from case law building on s. 8, not from the text of the section itself.

In practice, the risk area is the gap between someone raising a concern and the next disciplinary action. If the timing looks like retaliation, the employer will need to explain it. The safer practice is to document an independent business reason for any action taken close in time to a complaint, and where possible to keep the decision-maker separate from whoever received or handled the Code concern. Each Ontario statute keeps its own reprisal protection, so the same conduct can engage more than one regime.

Hiring: job ads, application forms, and interview questions

The Code’s right to equal treatment in employment does not start on someone’s first day — it bars job ads, application forms, and interview questions from classifying or filtering people, directly or indirectly, by a protected ground. It governs how a job is advertised, how an application form is built, and what is asked before a hire is made.

Three rules to keep straight:

• Job postings and invitations to apply. An ad or invitation cannot sort people, or signal the qualifications wanted, by a protected ground. This covers indirect signals too, not just blunt ones like “young, energetic team.”
• Application forms and pre-hire questions. The same rule applies to forms and to any written or spoken question put to an applicant. If it directly or indirectly classifies people by a protected ground, it is offside.
• Employment agencies. A recruiter or agency cannot discriminate on a protected ground when it takes in, sorts, screens, or refers candidates on the employer’s behalf.

The one real exception is at the interview: an employer may ask about a protected ground only where the Code itself already allows discriminating on that ground (for example, a genuine job requirement). That is a narrow door, not a green light.

Where employers trip up: well-meaning questions about availability that really probe family status or religion, “culture fit” language in ads that reads as an age filter, and assuming a third-party recruiter’s screening choices are someone else’s problem. They are not.

Equal treatment in unions and professional associations

Everyone has the right to equal treatment in joining a trade union, a trade or occupational association, or a self-governing profession, free of discrimination on the Code’s protected grounds. The Code reaches past the hiring desk; it also protects how people are treated when they try to belong to the organizations that come with a working life: trade unions, trade or occupational associations, and self-governing professions (such as a regulated profession’s governing college).

The rule is simple to state. Everyone has a right to equal treatment when it comes to membership in those bodies, and that membership cannot be denied or shaped by who a person is on one of the Code’s protected grounds. Those grounds span race-based characteristics (race, ancestry, place of origin, colour, ethnic origin, citizenship), religion (creed), sex and gender (sex, sexual orientation, gender identity, gender expression), and personal circumstances (age, marital status, family status, disability).

A few things worth knowing in practice:

• This sits alongside the Code’s other protections, like the one covering employment itself. So a person can be protected as an employee and as a union or association member.
• “Equal treatment in membership” is not just the yes-or-no of getting in. It covers how members are dealt with once they are in.
• It binds the organization, not only the employer. Unions, associations, and professional governing bodies answer to this rule directly.

Where people get tripped up: assuming the Code is only about the employer–employee relationship. If a workplace involves a union or a regulated profession, that body carries its own equal-treatment obligation.

How far does the duty to accommodate a disability go?

Before an employer can treat someone as truly unable to do the job because of a disability, it must show their needs cannot be accommodated without undue hardship. The Code spells out exactly three things that count when measuring undue hardship: the cost of accommodating, any outside sources of funding that could help cover that cost, and health and safety requirements, if any. That list is closed.

If an employee cannot do the essential parts of a job because of a disability, the Code says the employer has not broken their rights for that reason alone. But there is a big catch, and it is where most employers get burned: the employer must first show the person’s needs cannot be accommodated without undue hardship. That is a high bar, and the Code names exactly three factors:

• the cost of accommodating;
• any outside sources of funding that could help cover that cost; and
• health and safety requirements, if any.

That list is closed. Things people often reach for — grumbling co-workers, customer preferences, or general inconvenience — are not on it. A court or tribunal also has to weigh any standards set out in the regulations when deciding whether the line has been crossed.

In practice, the trap is jumping straight to “they can’t do the job” without doing the work first. The duty is active: the employer looks at what the person actually needs, explores real options, and only lands on undue hardship once it can point to genuine cost or safety reasons it cannot get around. Skipping that conversation, or assuming an accommodation is too expensive without checking funding, is how employers end up on the wrong side of a complaint. This substantive duty under the Code runs alongside the documented accommodation-plan process required by the IASR Employment Standard; the two operate together. Because the Code’s broad definition of “disability” includes mental disorders, mental-health conditions and burnout are squarely within this duty — see workplace mental health and burnout.
