Educational Support Professionals


The Educational Support Professionals (ESP) bargaining unit represents more than 800 casual, full and part-time members. Our dedicated members work in central departments and in elementary, secondary and alternate schools. They are ably supported by a pool of trained casuals.

 We are everywhere!

In elementary and secondary schools, the School Office Administrators, School Office Assistants and Library Technicians are all ESP members. In addition, Guidance Assistants and Instructional Support Services Technicians support us in secondary schools. Central departments (Admissions, Business and Learning Technologies, Finance, Human Resources) and the Ottawa School Transportation Authority (OSTA) are staffed by ESP members with a wide range of qualifications and expertise.



Melodie Gondek (President) and Leif Walther (Protective Services Officer) work out of the ESP-OSSTF office located at 9 Corvus Court in Ottawa.  MAP


If you are able to volunteer some time to become more involved in ESP activities, your participation would be most welcome.

Join a dynamic group!
