Workplace Video Surveillance in Ontario: What the Law Allows

Cameras in the workplace are common in Ontario — for security, loss prevention, or general oversight of a physical worksite. But workplace video surveillance sits at the intersection of several different legal frameworks, and getting it wrong can undermine an otherwise legitimate security measure or, worse, taint the very evidence you were hoping to rely on in a discipline case.

This article explains where the legal limits on workplace surveillance actually come from, and what a defensible surveillance practice looks like in Ontario.

Is Workplace Video Surveillance Legal in Ontario?

In general, yes. Ontario does not have a law that bans workplace video surveillance outright. But "legal in general" is not the same as "legal in every location and used in every way." Several separate bodies of law shape what is reasonable, and courts, arbitrators, and privacy regulators tend to ask a similar underlying question: was the surveillance necessary, proportionate, and disclosed — or was it a surprise, excessive, and used in a way employees could not reasonably have expected?

Where the Legal Limits Come From

• PIPEDA. Where footage captures identifiable individuals in the course of commercial activity, PIPEDA's principles around purpose, consent, and proportionate collection can apply — particularly for footage capturing customers or the public alongside employees.
• The Employment Standards Act, 2000. Ontario employers above a certain size must have a written policy describing how they electronically monitor employees, and must provide it to staff. Whether this specific requirement currently applies to your business depends on your employee count — confirm the applicable threshold directly, since size-based rules like this can change.
• General legal principles around a reasonable expectation of privacy. Ontario courts have recognized limited legal protection against intrusions into a person's private affairs in narrow circumstances, which is part of why surveillance in genuinely private spaces — washrooms, change rooms — is especially risky.
• Labour arbitration standards, for unionized workplaces. Arbitrators have developed their own body of standards for when surveillance evidence is admissible and how monitoring must be introduced, generally asking whether it was reasonable, disclosed, and proportionate to a real workplace problem.

Where Surveillance Is Especially Risky

• Areas with a strong expectation of privacy — washrooms and change rooms among them — should never be under camera coverage.
• Continuous, undisclosed monitoring aimed at general performance oversight, rather than a specific and articulable concern, is more likely to be challenged than surveillance installed for security and used only incidentally in a discipline case.
• Covert surveillance targeted at a specific employee, without a documented reason, is the highest-risk scenario — even where it may ultimately be justified, the lack of a paper trail makes it far harder to defend after the fact.

What a Defensible Surveillance Policy Looks Like

• [ ] A written policy describing what is monitored, where, and why.
• [ ] The policy actually distributed to employees, not just filed away.
• [ ] Cameras placed and framed to avoid areas with a strong expectation of privacy.
• [ ] A documented, legitimate business reason for the surveillance — security, safety, or loss prevention.
• [ ] A retention and access practice for footage, so it is not kept indefinitely or reviewed by people who do not need it.
• [ ] A clear internal process for when footage may be used in a discipline or termination decision.

Using Footage in Discipline or Termination

Surveillance footage collected without proper disclosure or a legitimate purpose can be challenged, and in some cases given less weight, precisely when an employer most needs it — in a termination or grievance dispute. Building the record properly before you ever need to rely on it is far cheaper than trying to defend a shortcut after the fact.
