The Ontario Secondary School Teachers' Federation is more than 60,000 members strong and was founded in 1919. OSSTF is more than teachers; they are educational assistants, continuing education teachers and instructors, psychologists, secretaries, speech-language pathologists, social workers, plant support personnel, attendance counselors, and many other education professionals. They only represent people in the field of education. No other representative organization has as much history and diversity in the field of public education in Ontario.
