    Reporting Student Absence, Late Arrivals or Early Departures

    Archbishop O'Sullivan Catholic School has a new  Safe Arrivals Program as of December 7, 2020, which allows parents/guardians to report their child’s absence in a new, more convenient way.

    Using the Safe Arrivals Program, parents/guardians are able to report daily absences (such as an illness, medical appointment, etc.) and even schedule absences in one of three ways:
    Download the School Messenger App from the Apple App or Google Play store
    Use the website go.schoolmessenger.ca
    Call toll-free to 1-844-445-4383
    These options are available 24 hours per day, 7 days a week, all year.
