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.

Cosburn Middle School (GR. 06-08)

A Great Place To Be!
Cosburn Middle School, located two blocks west of Coxwell Avenue on Cosburn Avenue, opened in 1949 as a Kindergarten to Grade 8 school. In 1950 it became a junior high school and in 1983, it was reorganized as a middle school.
We are very fortunate to have an outstanding facility, maintained at very high standards by an exemplary Caretaking Staff. Our teachers, support staff, students and community members all contribute to make Cosburn a safe and nurturing environment in which to work and play.
We serve approximately 600 students in Grades 6, 7, and 8 and offer a variety of opportunities for our students to get involved in our school!
