Employers sometimes monitor employees through cameras, computer systems, private investigators, or other forms of surveillance. In some situations, that monitoring may be lawful. In others, it may go too far.
Workplace surveillance in Ontario can raise serious privacy, employment law, and human rights concerns. Understanding where the line is drawn is not always straightforward, particularly where an employer claims it is investigating misconduct or protecting business interests.
This page explains when workplace surveillance may be permitted, where the limits are, and what employees can do if they believe they are being monitored improperly.
Insurance companies may also monitor employees who are off work and receiving benefits. Learn more here: Long-Term Disability Surveillance in Ontario

Can Employers Use Surveillance in the Workplace?
In some circumstances, employers may use surveillance in the workplace. Common reasons include investigating suspected misconduct, protecting property or confidential information, monitoring safety, or reviewing possible abuse of leave or benefits.
However, surveillance is not unlimited. Even where an employer has a legitimate concern, the monitoring must still be reasonable in the circumstances. Courts and decision-makers will often look at the purpose of the surveillance, how it was carried out, and whether less intrusive options were available.
Can Your Employer Secretly Watch What You’re Doing?
Sometimes, but not always. Whether an employer can secretly monitor you depends on several factors, including where the monitoring takes place, what the employer is trying to investigate, and whether you had a reasonable expectation of privacy.
For example, surveillance in public areas or common workplace spaces may be treated differently from monitoring in private offices, washrooms, or inside your home. Secret surveillance without a clear and reasonable justification may raise serious legal concerns.
Common Types of Workplace Surveillance
Workplace surveillance can take many different forms. These may include:
- video cameras in the workplace,
- covert or hidden video surveillance,
- monitoring of work computers or email,
- GPS or location tracking,
- private investigators following an employee,
- monitoring of social media activity.
The legality of these methods often depends on the context. Where the surveillance occurs, what the employer is trying to prove, and whether the employee had a reasonable expectation of privacy all play an important role.
Can an Employer Hire a Private Investigator?
In some situations, yes. Employers and insurers may hire private investigators where they believe there is misconduct, dishonesty, or abuse of benefits.
However, hiring an investigator does not give an employer unlimited rights. The surveillance must still be reasonable and carried out lawfully. Intrusive or excessive monitoring may create legal risk for the employer.
Surveillance While an Employee Is Off Work
One of the most common uses of surveillance occurs when an employee is off work due to illness or injury and receiving benefits. In those cases, an employer or insurer may suspect the employee is exaggerating or misrepresenting their condition.
This can also happen in disability claims. If your concern involves insurance monitoring while you are on leave, see: Long-Term Disability Surveillance in Ontario: Can Insurance Companies Spy on You?
What Are the Limits on Surveillance?
There are important legal limits on workplace surveillance. Generally, surveillance is more likely to be permitted in public places where a person has a reduced expectation of privacy. For example, filming someone in a parking lot or on a public street may be treated differently than recording them inside a private office or attempting to observe them in their home.
Secret cameras in highly private areas, or surveillance carried out without a reasonable basis, may be considered excessive or unlawful. Privacy principles are also discussed by the Office of the Privacy Commissioner of Canada.
Are Cameras in the Workplace Legal in Ontario?
In some circumstances, workplace cameras may be permitted. Employers may rely on cameras for security, safety, or investigative purposes.
However, the use of cameras must still be justified. The location of the cameras, the purpose of the monitoring, and how the footage is used will all be considered. Hidden or overly intrusive surveillance may create legal issues.
Video Surveillance in the Workplace
Video surveillance is often used where an employer claims it is necessary to protect property, investigate theft, or respond to safety concerns. However, not every use of cameras will be considered reasonable.
In E. v. Canadian Pacific Railway, the Federal Court examined workplace video surveillance and privacy principles under Canadian law. The decision highlights that the purpose, scope, and intrusiveness of surveillance are key factors in determining whether it is appropriate.
Computer, Email, and Digital Monitoring
Surveillance is not limited to cameras. In many workplaces, employers monitor emails, internet use, and activity on work-issued devices. While workplace policies may reduce an employee’s expectation of privacy, they do not necessarily eliminate it. The legal analysis can be complex and fact-specific. A leading Supreme Court of Canada decision is R. v. Cole, which addressed privacy expectations in a work-issued computer.
When Secret Surveillance May Cross the Line
In some situations, covert surveillance may support a legal claim by the employee. For example, in Colwell v. Cornerstone Properties Inc., a hidden camera was placed in a manager’s office without a credible explanation. The court found that this conduct contributed to a constructive dismissal.
If surveillance becomes overly intrusive or damages the trust in the employment relationship, it may raise serious legal issues. You may also wish to review: Constructive Dismissal in Ontario
What Should You Do If You Suspect Workplace Surveillance?
If you believe your employer is monitoring you improperly, it is important to proceed carefully. Helpful steps may include preserving relevant emails or policies, documenting what has occurred, and seeking legal advice before confronting the employer.
The legal answer will depend on the method of surveillance, where it occurred, and the justification provided by the employer.
