OSSTF/FEESO Limestone District 27 serves teachers and educational workers in the Limestone District School Board. It covers a geographical area from Kingston to Napanee in the south up to Sharbot Lake and Cloyne in the north. The District represents over 700 members including Secondary Teachers and Occasional Teachers (TBU), Professional Student Services Personnel (PSSP), and Instructors of adult, non-credit programming (IBU).


With over 4,000 members, District 25 is the second biggest and one of the most diverse OSSTF/FEESO districts in Ontario. We represent all unionized employees, with the exception of elementary teachers, at the Ottawa-Carleton District School Board.


OSSTF/FEESO District 28 represents Office Managers, Early Childhood Educators, Teachers and Occasional Teachers working in the Renfrew County District School Board (RCDSB).  A very rural Board set in the beautiful Ottawa Valley and bordered by Algonquin Park, we have schools stretching from Deep River to Arnprior and Palmer Rapids!


OSSTF/FEESO District 26 was created in 1998 as a result of the amalgamation of four local predecessor school boards.  District 26 is one of the largest geographical districts in OSSTF/FEESO, serving members from Hawkesbury, to Cornwall, to Gananoque, to Almonte.   District 26 represents approximately 1000 members across three bargaining units:  Secondary Teachers, Secondary Occasional Teachers, and Professional Student Service Personnel.
