Ottawa gets a real winter: sustained cold, significant snow, and occasional freezing rain when a warm nose overruns the valley. The saved profile uses typical snow tolerance and high cold sensitivity, so a very low wind chill moves the score even on a dry morning. The urban setting slightly eases the bus score inside the city.
The Ottawa-Carleton District School Board serves the city's public English schools. The Ottawa Student Transportation Authority's site addresses families in the OCDSB and the Ottawa Catholic School Board. School buses and OC Transpo are different systems. A school-bus cancellation is not an OC Transpo shutdown.

Questions parents ask
Does this score include Gatineau?
No. Gatineau is in Quebec and uses a different school system. Search Gatineau or a J postal code if that is the morning you care about.
Where do OCDSB families look for buses?
The Ottawa Student Transportation Authority site, ottawaschoolbus.ca, which the OCDSB points to for transportation. The board site is still the place to confirm whether schools themselves are open.
