The Waterloo Region District School Board (WRDSB) has revealed further details about a hack that saw information stolen from its system earlier this summer.

On Tuesday, the board issued a statement warning parents that some students won’t be able to catch the bus on their first day of school.

“Unfortunately, the cyber incident that occurred last month has impacted Student Transportation Services of Waterloo Region (STSWR). We apologize for the inconvenience this will cause students and families,” the school board said.

The biggest impact will be for students who have moved in the past three months who will have their school bus service start on or after Sept. 19, according to the school board.

The first day of school is Sept. 6. The school board said most students will be able to ride the bus on the first day. Students assigned to taxis will also have a Sept. 6 start date.

Students enrolled in special education programs and students whose routes use small or adapted vehicles will have transportation service begin on Sept. 12.

The school board said this includes the following routes:

  • All bus routes from 700 to 723
  • All bus routes from 800 to 862
  • All bus routes from V01 to V39
  • All bus routes from W01 to W45

Families can visit the STSWR website after Aug. 29 to find information about what bus route their child is on.

CTV News reached out to the teacher’s unions about the issues facing the school board. The elementary teachers were unavailable, but the local union representing secondary teachers said in an email it is hopeful for a smooth return to school.

According to the board, a new registration system is up and running and they don't expect any issues.

A spokesperson for WRDSB said the "online registration system was unavailable from July 15 until Aug. 16 as we moved to a new student information system. But registration is up and running as usual and families shouldn't have any issues"

Starting next week is when most schools will have time-tables and course schedules should be ready.

When asked for an interview, WRDSB said no one was available.
