In most Ontario workplaces, there is no law that prohibits employees from dating each other. Unless your employer has a specific policy restricting workplace relationships, two colleagues entering a relationship are generally free to do so.
However, freedom to date does not mean freedom from consequences — particularly when the relationship involves a power imbalance.
The Power Imbalance Problem
The most legally sensitive workplace relationships are those between a manager and a direct report — or between any two people where one holds authority over the other’s career.
These relationships raise serious concerns because:
- The person in the less powerful position may feel pressured — even if no pressure is intended
- Consensual relationships can later be reframed as harassment if they end badly
- Other employees may perceive favoritism, which affects morale and team trust
- The employer may face liability if the relationship affects workplace decisions
A relationship that feels entirely mutual can look very different from the outside — and from a legal perspective, the power difference matters enormously.
When a Relationship Becomes a Legal Issue
A workplace relationship crosses into legal territory when:
It affects employment decisions — if a manager promotes, favors, or gives preferential treatment to a partner, that is a problem for the employer and potentially for other employees who were passed over.
It creates a poisoned work environment — if other employees feel uncomfortable, excluded, or disadvantaged because of a colleagues’ relationship, that may constitute workplace harassment under the Occupational Health and Safety Act.
It turns into harassment — if a relationship ends and one party continues unwanted contact, pursues the other person at work, or uses their position to punish the other party, that is sexual harassment — a serious violation of both the OHSA and the Ontario Human Rights Code.
It involves a significant power gap — courts and tribunals look very carefully at relationships where one person controls the other’s salary, schedule, performance reviews, or job security. True consent is harder to establish in these circumstances.
Disclosure Policies — What Some Employers Require
Many larger employers — particularly in financial services, healthcare, education, and law — have written policies requiring employees to disclose a workplace relationship, especially when one party supervises the other.
If your employer has such a policy and you are in a workplace relationship, disclose it. Failing to do so when required can result in disciplinary action — not because the relationship itself is prohibited, but because you violated a workplace policy.
What Happens When the Relationship Ends
This is where workplace relationships most commonly become legal issues. When a relationship ends badly:
- One party may allege harassment if the other continues unwanted contact
- A manager may consciously or unconsciously treat a former partner differently — in scheduling, performance reviews, or opportunities
- Either party may feel the workplace has become hostile or uncomfortable
If you are in this situation — on either side — document your interactions, keep communication professional, and seek HR support if needed. If the situation escalates, speak to an employment lawyer.
For Employers — What You Should Have in Place
A written workplace relationship policy — Consider requiring disclosure of relationships involving a power imbalance. The policy should be clear, consistently applied, and non-punitive for disclosure.
A conflict of interest protocol — Where a relationship involves a supervisor and a direct report, consider reassigning reporting lines to remove the conflict. This protects both employees and the business.
A strong harassment policy — Every Ontario employer with five or more employees must have a workplace harassment policy. It should specifically address sexual harassment and unwanted conduct following the end of a relationship.
Training for managers — Managers need to understand that their position creates risk in any personal relationship with a direct report — regardless of how mutual it feels.
The bottom line: Workplace relationships are a reality — and Ontario law does not ban them. But they come with responsibilities. A relationship that starts well can create significant legal problems if it involves a power imbalance, affects workplace decisions, or ends in a way that makes the workplace uncomfortable or hostile for either party.
If you are an employee navigating a workplace relationship — or an employer trying to manage one — knowing where the legal lines are is the first step to staying on the right side of them.
