All CBE schools are required to practice lockdowns in the same way that we practice fire drills. The procedures for lockdowns are developed with the Calgary Police Service and are part of each school’s Emergency Response Plan. If you have questions about lockdown drills or lockdown procedures, please contact your principal.

Evacuation Procedures

In the event that the school needs to be evacuated for any reason, all staff have been trained according to CBE standards. All schools have a primary and a secondary evacuation site. In the event of an evacuation, you will receive an email, phone or SMS notification from the school.
