Education Minister Clyde Jackman said in a statement Monday that a number of privately contracted school bus operators have indicated plans to withdraw their services.
The statement did not offer details on why the bus operators wouldn't honour their contracts, and a spokeswoman for the Education Department could not be reached for comment.
Parents are being asked to make alternate arrangements to get their children to school when classes resume Wednesday as a precaution.
Jackman says school districts will advise which routes will be affected as information becomes available.
Meanwhile, Jackman says the government is prepared to talk to representatives from the Newfoundland and Labrador School Bus Owners Association and private operators about any concerns they may have.
No one from the Newfoundland and Labrador School Bus Owners Association could be reached for comment.
School boards in the province use both board-operated and privately contracted bus services for their nearly 48,000 students.
