Two teachers used a private cloud document to record frustrations about workplace matters. They shared access to the document, protected it with a password and did not intend it for school administration. The principal learned of its existence. On an occasion when a teacher was away, he encountered an open school laptop, moved the mouse, read what appeared and photographed portions of the document. The messages were then used to reprimand the teachers.
Their union grieved the reprimands. An arbitrator rejected the privacy complaint, but the dispute eventually reached the Supreme Court in York Region District School Board v. Elementary Teachers' Federation of Ontario, 2024 SCC 22. The school board argued that the arbitrator's workplace privacy assessment should stand. The Supreme Court disagreed.
The Court held that Ontario public school boards are government actors for purposes of the Canadian Charter of Rights and Freedoms. Teachers therefore have protection against unreasonable search or seizure under section 8, including in their workplace. The arbitrator erred by assessing the principal's actions without applying that constitutional protection as a legal constraint. The Court dismissed the board's appeal and left the arbitrator's decision set aside.
The decision doesn't mean that every document on an employer supplied laptop is private, or that management can never investigate workplace misconduct. Reasonable expectations of privacy depend on the circumstances and the nature of the search. But a public employer cannot bypass the Charter by characterizing its actions as routine supervision.
This is particularly important when employees work across shared devices, personal cloud accounts and workplace systems. Technical access isn't identical to legal permission. A manager who can open a document still has to consider whether doing so is a justifiable search. Organizations should distinguish legitimate workplace oversight from reading private material simply because an opportunity presents itself.
The Charter holding turns on the school board's public character. Private employers may still face statutory, contractual and arbitral privacy duties, but the constitutional route isn't automatically the same.
