Toronto District School Board

The Toronto District School Board and Toronto Catholic District School Board are experiencing school bus delays. In particular, parents of students who use Attridge Transportation, Wheelchair Accessible Transit or Sharp Bus Lines should expect significant delays and the possibility that some buses may not be running due to an unanticipated bus driver shortage. We are working to fix this issue as soon as possible.
