On July 3, 2026, a school‑board email meant for internal distribution was sent in error and included personal details of parents of students at Rosemère High School in Rosemère, Quebec. The mishap exposed sensitive information to a broader audience than intended, prompting immediate concern among families and education officials.

The email, described by the school board as a mass communication, contained data that is typically considered private, such as names and contact information of the parents. Because the message was inadvertently shared beyond its intended recipients, the personal details of a large number of families became accessible to unintended parties.

In response, the school board issued a statement acknowledging the mistake and confirming that an internal review has been launched to determine how the information was stored and why the email was distributed incorrectly. The board said it is working with its IT department to assess the breach and to reinforce safeguards around the handling of personal data.

The incident has raised broader questions about the security practices of school administrations in Quebec. Privacy advocates note that educational institutions hold extensive records on students and families, and that robust protocols are essential to prevent similar exposures. The board’s review is expected to examine existing data‑management policies, access controls, and staff training procedures.

Parents who received the email have been advised to monitor their personal information and to contact the school if they notice any unusual activity. The board has pledged to keep families informed as the investigation proceeds and to implement any recommended changes to protect confidential information in the future.
