Elmira District Secondary School is expected to reopen Tuesday after being closed Monday due to an anonymous message sent to a school administrator.

The message was sent Sunday morning. Its contents have not been made public, other than that police say it did not “explicitly” mention weapons.

Officials say that the message was concerning enough to prompt a call to police and the decision to close the school.

“The concern is not only for that student, but the safety and well-being of everyone in the school community,” Waterloo Region District School Board superintendent Peter Rubenschuh said Monday.

As of Monday afternoon, neither police nor the school board had been able to identify the person who sent the message.

“We would really like to speak to the individual, identify them (and) offer them support,” said Rubenschuh.

Exams scheduled to be written on Monday will instead take place on Tuesday, with the exams planned for that day bumped instead to Thursday.

Anyone with information that might aid police is asked to call them at 519-653-7700 ext. 6399.
