A water main break means Georgian Bay Secondary School in Meaford will be closed Friday.
Trivia night and GBSS Orchestra have been postponed to a later date.
A semi formal event scheduled for Friday night has also been postponed.
Students involved in this week's music clinic should stay tuned to the GBSS Principal Facebook page or school website for updates.
Municipal staff are working on repairs to the water main, but there is no timeline as to when the work will be completed.
