On July 2, 2026, the Sir Wilfrid Laurier School Board distributed a mass email to the parents of students at Rosemère High School. The message included an attachment that listed personal information belonging to those parents, exposing details that were not intended for public distribution.

The email was sent from the board’s official communication system and was addressed to the entire parent body of the high school. The attachment, which was part of the original correspondence, contained names and other identifying data of the recipients. The inclusion of this information in a single file made the personal details accessible to all individuals who received the message.

The Sir Wilfrid Laurier School Board oversees a network of schools throughout the Montreal area, including Rosemère High School. As the governing body responsible for educational administration, the board manages communications, enrollment records, and other student‑related services for families across the region.

The inadvertent release of parents’ personal data triggered immediate concern among the affected families. Recipients reported anxiety over the privacy breach and questioned how the information had been compiled and shared. The incident highlighted the sensitivity of personal data handled by educational institutions and the importance of secure communication practices.

Following the discovery of the error, the board acknowledged that an attachment containing parents’ personal information had been mistakenly included in the email. While specific remedial actions were not detailed, the event underscored the need for careful review of electronic correspondence before distribution to large groups.

The episode serves as a reminder of the potential risks associated with digital communications in school settings, especially when handling sensitive personal information of parents and guardians.
