Late Policy - Students who receive three or more late slips in the term will face a lunch detention the following day for each late. Skipped classes will also result in a lunchtime detention the following day.

Lunch - The cafeteria will be serving. Students need to know their account numbers in order to purchase food. Students may leave the building to buy lunch in the immediate area (St. Clair and Yonge).

Cell Phone Policy Update - Students are not permitted to use their cell phones or mobile devices during the school day. If students are found using their cell phones without permission from a teacher, the device will be confiscated to either the front reception or the Middle Senior School office and returned at the end of the day. If parents need to reach their child, please call the school to relay a message.

Uniform - Students are expected to wear their school uniform. Please review the uniform components here, as we have made a few changes this year. Students will be given a two-week grace period to be in Uniform with the expectation that all students have the appropriate pieces to the uniform by September 22, 2025.
