All buses in Kenora, Dryden and Vermilion Bay have been cancelled for today.
The Northwestern Ontario Student Services Consortium states this is due to road and weather conditions.
Much of the region has a chance of light wet snow and risk of freezing drizzle with the mercury expected to lower down to minus four, with wind which could further complicate matters.
Additionally, bus SL52 has been cancelled as a result of a driver shortage.
