Cosburn Middle School's Mission Statement

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 650 students in Grades 6, 7, and 8 and offer a variety of opportunities for our students to get involved in our school.


Providing a balanced literacy program that engages all learners is our goal here at Cosburn.  We have established a unified literacy plan that focusses on the explicit teaching of critical thinking skills which will enable our students to make well rounded choices as they progress through life.

Our planning is data driven and focussed on meeting the needs of our students. Our teachers are constantly engaged in professional learning to meet the ever evolving needs of our students.

Student Life - Where You Belong


Cosburn Middle School provides various programs to engage our students.  We offer many co-curricular programs which allow them to display leadership, and master their social skills.  Our Me to We and School Council continue to foster student leadership by allowing their voices to be heard, and their actions to be respected.  They have engaged in many charitable endeavours that are a testament to the wonderful students we have here.
Our ECO club has led our school through many environmental awareness initiatives and have educated our students and staff on the importance of eco-awareness and energy efficient practices.  This leadership has spawned a Gold level Eco School status and this year we are going for Platinum!
Other Student leadership opportunities include:
Girls Mentorship, Student Announcers, Library Helpers, GSA, Athletic Council, and House League.


Our dynamic staff and student body set us apart from other schools.  Being a quadruple track school with a multitude of extra-curicular activities allows us to be a vibrant school community that is always on the go!  Our focus on providing opportunities for our students in and out of school is something we are extremely proud of here at Cosburn!
We want our students to take ownership, rather than membership in their education!  To do this, we need to provide them with opportunities to make well-rounded decisions that will positively affect our community.


Cosburn School Council is very active at Cosburn.  Regular meetings provide opportunities for parents to learn and speak about current school and educational issues. All parents are welcome.
Parents are encouraged to become involved with both parent groups. Contact information is available on our website:
