Eligibility for yellow school bus transportation

Yellow school bus transportation is provided to students depending on their grade level and the distance from their home or caregiver to their designated school. Specified high school students with access to public transit (OC Transpo) will be provided with bus passes or tickets for the months of September to June.

Transportation is provided for students who reside (or caregiver resides) within the following distances from their school. Transportation will not be provided if the residential or caregiver address is less than the designated distance detailed below. Students attending schools outside of their regular attendance boundary will be responsible for their own transportation.

  • Junior & Senior Kindergarten - 0.8 km or more from their home school
  • Grades 1 through 8 - 1.6 km or more from their home school
  • Grades 9 through 12 - 3.2 km or more from their home school

Variable transportation for students with two homes

The Ottawa Student Transportation Authority (OSTA) will provide transportation services to students in a joint custody arrangement that have two homes – if both homes are within the attendance boundary and they are eligible for transportation. A formal application is required. Both parents and/or guardians must sign the application and provide a schedule. Read more about variable transportation

Applying for an empty seat on a bus

If there are empty seats available students may be provided transportation even though they reside in the designated walk zone. All empty seat applications and approvals go through OSTA. Please see the Empty Seat (Seat Availability) Provision page on their website.
