How Simcoe County bus cancellations work
- School board: Simcoe County District School Board (SCDSB)
- School board: Simcoe Muskoka Catholic District School Board (SMCDSB)
- School buses: Simcoe County Student Transportation Consortium (SCSTC)
- SCSTC and the bus operators make bus-cancellation decisions, usually before 6:00 AM, and aim to post them between 6:00 and 7:00 AM on the SCSTC website, its X account and local radio.
- A morning cancellation applies to the whole day, and it can cover one weather zone, several zones, or all of Simcoe County. SCSTC lists the zone for each school.
- SCDSB says its schools remain open when buses are cancelled; students who stay home can use the learning platform their teacher assigns.
- SCSTC weighs road conditions, current and forecast weather, visibility, snow or freezing rain, and whether plows have been out.

Simcoe County snow day questions
Are Simcoe County schools closed when buses are cancelled?
Not usually. SCDSB says its schools stay open for learning when SCSTC cancels buses, unless a separate closure is announced. Catholic-board families should check SMCDSB notices.
Is the weather disruption signal a bus-cancellation prediction?
It is a guide, not a separate model. It adds the closure and delay chances from the same weather model used everywhere on this site. Because Simcoe County usually cancels buses rather than closing schools, a higher signal mainly means a higher chance that buses will not run in at least some zones.
