Police say the situation was resolved quickly and the school returned to normal operations
Police presence briefly prompted a lockdown at Gravenhurst High School earlier today, but the situation was quickly resolved. Initial reports indicate the lockdown lasted only a short time before being lifted by local officers, and there is no indication of any ongoing threat to students or staff.
Details remain limited, and authorities have not released further information about what led to the precautionary measure.
Officials say the school returned to normal operations shortly after the lockdown ended. Updates are expected if more information becomes available.
